Inside a Huge PCB Factory - in China

Show Video

Circuit, boards are in just about every piece of electronics, in our lives but. How are they made and, why the heck is it so yellow in here today, we're. Gonna find out. Printed. Circuit boards or PCBs, may look really complicated but they're actually pretty simple they're, a bunch of tiny copper wires sandwiched. In between multiple. Layers of fiberglass. Now the wires are, there to connect all of the various integrated, circuits and other electronic, components, in an organized, repeatable, way to make up an electronic circuit today. We're. Gonna see how they're manufactured, I'm, here at the JL CPCB Factory, in play Joe China which, is outside of Schengen and I'm, here with Lilly who's. A technical. Support representative, that talks to engineers, all day long who, sends you design files for, PCB is to have you manufacture, them and so you know everything, about this process and you can answer any question I might ask right. Not. Every question so, you brought someone with you. Great. To have you mr. leo and you can answer any question that Lilly doesn't know the answers yeah. Great. I'm. Really excited to see this process step by step but. First we, need to rewind, a couple hours and go back to your main headquarters in, Shenzhen to see the very first step. So. We're here at your headquarters yeah. And, this is where the first stage in the process happens, right where. The very first thing, when, a when a customer, sends in their file to have a board designs it, happens here this is our, engineering. Department. This. Is where they review the design files to make sure there are no problems yeah. Yeah he's checking where, this fire, is okay for example Reza Sayah is some layer list. Whether. There has a, folder, for the fire weather, yeah whether the shooting fire is there yeah so he's just making sure that the engineer who designed this the customer didn't. Design it in a way that you can't actually manufacture, yeah, so he makes the production file and then he sends that over the Internet to the factory yeah and then the next step happens at the factory yeah right yeah, okay let's go back to the factory and see the exit okay let's go so, this. They're, printing, the design on, to, clear. Film here, Wow. So. These, now we're, gonna go see where they take this film and they, use this they use light to project this image onto, a. Board that, has some photoresist, on it that, will then expose similar, to how you would expose. A photograph, now we've got the design we need to transfer, it onto a copper, circuit board blank but. First we've got to prepare that blank so let's go see where you guys do that oh. I. Have no idea it comes this big so, we have to cut it of course, okay. So this. Is. Your, fr4. Fiberglass, yeah you. Have two coppers, on the top, and the bottom vaminos, yeah. When we remove the copper, then say yellow, yellow, pause that's the so called epithelium. Right what is your fiberglass, so that's your fiberglass, in between and, then the copper. Is our knee sandwich already glued on the outside yeah yep got it and so this, is the. Circuit board before. Anything's, been printed on it this, is the raw raw. Material, yeah that's, really cool so the next step is you cut this down you take these big sheets and you cut it right yeah oh wow. Okay. This, is crazy, this is the original size for this material and. So you're picking this up here and then this is a cutter machine here. So. It starts out as one piece here and it's getting cut down the middle by a song so, what's going on here it looks like it's. Cutting. The edges. So. Maybe man is very smooth got it so. Next what are we gonna see review see how the in in a year it's made of pressed yeah cut it and so these are the wires that run in, the middle of the board where you can't see them yeah okay so we got to put on outfits. This. Is like a proper clean room so we really don't want to damage the the, boards that are being made by right now by like bringing in too much dirt and dust yeah.

Tell. Your boss thank you for, letting us come and see the inside I've never gotten to see this, area. Are. You ready yeah, so we'll go through here. So. These are the boards that we saw yeah, been cut in the other room yeah so they have to load. Back. The joy-filled. On, homicide, and. Sigh okay so when they expose, this material, to light it gets hard and it sticks to the board and, in places where there's no life in where there's black. In the image. This. Disk, will wash off and that. Will protect the copper from. Being, dissolved. By, the alkaline, bath we're gonna see later in the process so now, that the film is on the. Blanks. We. Need to actually apply, the design right, so. She's got books like two films, there sandwich. Together. At. The same time. Oh I, see, and it's doing it behind behind there or, gets it oh I, see there's a light in the corner oh and, you could you can see the design already. So. Why. Are all, the lights of yellow in there. Because. The view, is ligh sensitive. Yeah. So we don't need allies so strong if, it if the lie is strong, then maybe the field will, be exposed, right because, the light is sensitive to blue light or that the film is sensitive to blue light and that, will make it hard and so, the yellow light doesn't affect it I understand. That. This stack of boards is ready to be developed, and they're, gonna feed it through the wall and, so. Then, that will go into the rest of the developing process yeah. Okay, so but I bet we have to take off the bunny suits and go outside to go see that okay. All right let's go all, right here we go this is like an activated, charcoal mask. This, is where we just were and. And, now, the boards are coming through that have been exposed to the light and now, they're going through the developing, process, everywhere. That there's copper, the. Copper is going to get removed so developing, over here where we wash off the excess. Photoresist. And then here is the actual etching process, and this, is like an alkaline, solution that. Removes. The copper chemically, a whole bunch of chemicals, going on here we totally can't see inside, but. When. We come out to this side. Have. A look now, where, there was copper back there there's. The yellow which. Is the fr4, right, that's. The fiberglass and. It's in that in the middle, got. It and so. Underneath this blue is, still the copper that we want to keep so, then it comes around over here then, it's yeah it says here film stripping, so that's removing, the blue now on top of the copper okay so it's a bunch of washing, and removing, oh there. We go the, blue has been removed and it just leaves the copper underneath that it was protecting, and now, we have our designing copper, so that this, is starting to look like a circuit board and.

Then. Drying, it looks like and. Then it's putting a protective, layer in between so they don't scratch each other each one of these now is a finished, inner layer is that right it's. Done, so. Next. You. Need to inspect, the, etching on the inner layer and make sure that everything is okay right this, is, very cool this is an automatic, robotic, inspection. Right you. Guys call this Aoi. Optical. Inspection, and. Then it's scanning it with like a light and a camera. It's. So, fast and so this is comparing, what the board looks like with. What, the design file is supposed to look like and so then when this is done then. This goes to be sandwiched with the with the copper on either side of it let's. Go see that this, is the clip, back we, we, call it CP we. Can see the light here, is its domain the surface may laugh we. Call it round, Tobin that put the PV to it to. Increase. The. Fighting. Boys. Binding, force let me see if I can really explain that a little bit. This. Machine, Witzel. Takes. The smooth surface, and makes, it a little bit more rough yeah so that when you put the prepreg, on there which is sort of like an epoxy glue, that. It can get, into the surface and find more and more strong. So, this is like a like, a sheet of fiberglass but, it's really thin it's flexible, and it, has an epoxy already, already. Impregnated into, it already soaked into the fabric I see and then you're gonna put this here and then we're gonna put another piece of copper and and. The sandwich oh. Wow. This. Is a huge, machine so. This copper, foil is the outside. There's. Only one worker for this whole area, could. Be one person so. That's the bottom topper now the. Prepreg, and the middle and the top. Yep and then, peepee and then another layer of copper and, then one of these metal sheets, one. Big sandwich. This. Is the room we were just in right okay. Oh and, he's about to bring some out right now oh. Oh. These. Are the board's that we just saw being stacked together I'm glad. He told me I would have gotten to run over well, let's go chase that robot cuz that's got the other stack right so, there goes the stack that that, the first stack that we made in, here is the press this is where they come next definitely, no safety rails here you just have to be standing out of the way oh. This. Is where he controls, they, do increase, the temperature. Sometime. Later. And then increase it to 200, I see, so this is the steps it goes through the basic deal is you load this in the furnace. Pressure, and heat up to 200 degrees and. You. Know 27, kgs, of pressure. That. Will melt, the epoxy, in the prepreg and stick. It to both sides and then, and then it comes out here and we can see the finish the finish yeah. Lamination, okay let's go take a look so this is what, it looks like when it's fully laminated, this is the copper wow, that is super thin, this. Is like yeah paper thickness maybe even thinner so inside, that is the inside layer that we etched and now, it's got two pieces of copper foil on the outside now. Now. It's four layer now we need to drill some holes all. The holes yeah, this, is the drill room oh my. God you guys have so many drilling machines underneath. All of this all. Of this stuff is the, circuit boards that we just saw right. And. They're in a standard why they're stacks are like three and, these are all the drill bits here yeah these machines can automatically, change what drill bit they're using yeah they they can drill all different size holes depending, on the design and, they. Just come out here and they they put. The one that they've been using and they pick up a new one and they go back in the kitchen oh it's here it's doing it it's switching heads okay switching bits so, these boards are fully drilled and Louch these.

These Are little, tiny deals there are two kinds of bowls three. Kinds of poles in, a circuit board there RVs, there's. Through-hole, and then, there's just a mechanical, hole right. Yeah, like for putting screws so. So. Those are obvious those are promoting screws and bolts and things through those are these big holes around the outside then, through holes are for putting the, legs of components, through like resistors, capacitors. Right, yeah, and then vias these, vias, are the magic that makes circuit boards work makes multi-layer. Boards work when you've got wires on the top of your board and wires on the bottom of the board the, vias are what connect those two sets of wires together so, you drill a really tiny hole and then, you have to send two late. Copper, in, that hole so that it connects the two yeah, I can't, believe how big this drill operation, is so how many heads is this this is one, two three four five six, heads yeah, so they're all doing the same thing the whole time and. They're all working on their own stacks, of boards which, all have to be perfectly, aligned to each other so next, we'll go see plating, where. Where we actually put copper back in the holes okay. So, this is a copper, plating, process. Where. Every pole, has copper plated, on the inside this. Is a chemical process that I don't fully, understand, if you're a chemist and you, understand this process better than I do leave a comment in the comments and I'll make, sure it gets visible, I'm not sure I fully understand, what all is going on here, but. The. Important takeaway is. That we're putting copper in the holes. So, we talked to mr. Vieau and. It turns out we only saw half the process. This. Is the other half before we it was doing copper plating, but it was just putting a really thin layer. Right. Not thick enough for soldering and for oh you know electricity to flow through. Right. So this is an electroplating, line, but but in. Order to electroplate, you actually need to be able to run electrical current through it and the, first step gave us enough copper to be able to do this and then this will grow. The thickness of the copper in those holes. So. Now we're back in, the dark room. And this time we're putting the traces, on the outside of the board right. Okay so this process is exactly, the same as what we saw for the inside layers so. Let's go ahead and just skip ahead to the next step. So. This is a why again we saw Aoi for. The inner layer. Are. These, machines on any different than the ones downstairs. Same. Exact thing so, this. Is where. You apply the solder mask which, gives circuit boards that unique, green color yeah right so far they've been yellow turning.

Them Green you can do other colors too but green is what, everybody thinks of when they think of soluble. Yeah. It's. Liquid solder mask and. Your, squeegee aiming it on with these sweeties it. Goes back and forth so we're putting it everywhere here, and then in the next step we're gonna remove some of it yeah on, this machine, we're, only soldering, or or only putting solder mask on one side of the board right yeah but we want it on both sides okay. Right. Okay, so. Let's go down here oh I, see so you've got two machines that are exactly the same oh and, you've got you've, got a robot arm that, flips it over in the middle that is, super cool and then, next where do we go we. Have to make. Giant. So, you've got these big industrial dryers. Here, oh I, see, okay so all the board's are vertically, stacked up here yeah, it is, a jointer. That just makes the solder mask kind. Of tacky dry, so that it doesn't run off so. Next, we. Need to go see how we remove, the solder mask off the pads where we don't want it they, cover the, field, on. This, PCB the fil have the openings. For, the. That, means with. Me to remove, these. Films that printed out the same way to put the film as we saw for the traces yeah and, anywhere, there's black. Yes solder mask is gonna be ruined they put black where there are pads or, other things where we don't want Tata mask to, stick yeah, so he's taking boards that have, solder mask everywhere and he's putting the films on, both sides yeah so. I think this. Solder mask is UV. Curable, UV. Light and, so. When you expose this solder mask to UV light it. Makes it hard and. So. What that's what this bright, purple light is over here is a. UV light we're, just hearing the. Solder mask everywhere. That the the film, is clear and, anywhere it's black it's, it's staying uncured, and then. We can wash it off. That's. The washing line in there. This. Is the other side of the clean room where the boards were going into the wall. Come. Out in here and this looks just like the developing, line that, we saw on the in the etching process, right. So it's basically, just water, sprayers, that are moving back and forth and and spraying, off all the excess solder mask right that the solder mask that didn't get hardened by the light so we can see here, the, boards, are, have.

The Solder mask removed, from the pad so we can see the copper pads. That's. Awesome, now it's. Time to put some markings, on these boards this. Is. Your. Silkscreen, process and this, is just. What you would expect this, looks exactly like a t-shirt silkscreen. Yeah, it's a big frame and it's, got a piece of silk stretched in the middle and then. On there. Is the design, from. The design files of where, the. Engineer, has, drawn silkscreen, why do engineers, put a silkscreen on the board. Their. Logos. Maybe. Or. Special. Yeah. So they'll put text that says like what each component is. Alignment. Lines for, where where components, are should be on the board it's, purely for humans, right it has no electrical, purpose but, it's usually for humans to know what goes where how should it be aligned, logos. Part. Numbers things like that and in your life now, this is not the only way you do this you. Have a different machine so. This looks like a giant, inkjet. Printer like. What you would have at home, but. Maybe. With a UV, cured, looks. Like a UV cured. Inkjet. Printer why, do you use, the, old method at all why not do it all with this machine it's, only. The, quantity. It's twice more ah they, think that bitch won it's much. Lower, event, fashi time I understand. So, if they only have a few they, use the slower machine that. Doesn't require making silk screens but, if they're gonna make a lot then. It's worth making a silk screen and they can do it much faster so now we've got all the labels and the outlines, printed, on our board let's. Go see the next step the boards are coming out of the. Ovens that that, finishes the globe strand makes it hard and now. They're coming into surface treatment a service treatment on the copper that makes it easier to solder right. So it makes it perfectly flat and, and. Makes the solder stick better so, there's, a couple different options here, but this one is called hassle, hot. Air service, leveling right. Wow. So. The board is tipping down into the liquid solder. And. Then they pull it out and there's there's hot air blades, that blow. Off all the all the excess you, can tell it. Goes in copper, and it comes out silver. Okay. So. This, looks like the drill machines we saw before we're not drilling holes anymore right. On. One big panel. So. We have to cut out each PCB. According. To the shape the designer. Specified. Drew, these are basically cutting bits that are cutting around the, edges of each circuit board, so. What is this room. Okay. So this is related to what we just saw cutting. Out the profiles but it's a little different. Before. We, go. Our. Tennessee so each of these is a separate board right. But they receive it like this they'll, place all their components, on there in, their pick and place machine or, whatever and. Then, snap, it apart okay. So the V score here this machine makes. That makes that scoring cut so that it's easy to break it he's, getting a stack ready to go into the machine here oh. Wow. That's so fast. We. Have our finished boards we're done right no we have to test whether the. PCB. Is all okay. And. That's. The most important part right we, have to make sure that the things that should connect do connect and the things that shouldn't connect don't, connect so this is your, a testing room if. We, use flying, poke passing, this is one of my favorite machines in a PCB Factory they've, got little tiny. Needles. On the end of these arms, right and those, touch each of the pads on the, circuit board where, a component, is going to be soldered down. So. They're testing the, electrical. Connection, between, two, arbitrary pads, right. And the computer, knows. Where all of the pads should be because, it has the design and, it knows what should connect together and what shouldn't connect together and it, tests all of the combinations, of that one by one yeah, that's, amazing. Finally. Though. We. Have finished, circuit boards here, fully. Tested, wholly, manufactured. And ready to go to the customer yeah. So what's the last step. Packaging. And shipping so. This is a an, example ready, to ship it's got a label on it yeah ready, to go out to the customers once it's all packed up and ready to go it, gets shipped out to the customer so gets packing labels and and, on. Its way and. So how long we've, seen this whole process this is the very last step of shipping out to a customer how, long from, when the customer, submits their design until. It gets shipped out. When. It's, put into production. Is. It maybe four, hours four. Hours not, so, fast. Yeah so, in the u.s. sometimes. Weeks, is typical, or to, wait from the time that you submit your order to the time that it's ready to ship I know you have. Customers. In the US and Europe how long does it typically take for, shipping on top of that. DHL. Shipping three days so you're looking at you, know four days from the time you submit your file to the time you have your boards yeah four days that's pretty darn fast well.

I Think that about does it for this time I really. Enjoyed that I enjoyed seeing the full process I think, I had a couple interesting takeaways, from that I think. The biggest one was just how complex, this process is there, are so many steps and you have so many different boards, so many different designs flowing, through your Factory it's. Amazing, that you guys keep all of this straight that you keep track of whose orders or what and there. Are so many details you have to get right there's there's keeping things aligned, and keeping things clean I'm so, impressed I, hope. You guys enjoyed, this. To her as much as I did I wanted, to thank jlc PCD for sponsoring, this video and making it possible but more importantly I wanted to thank you guys for, giving me such deep. Access to your factory such complete access you, in particular mr. leo have been very accommodating and letting us go into all of the clean rooms and, see all of the different areas it, makes a big difference and Lily, and mr. Leo thank you so much for taking the time to show me around and the rest of your team I really. Appreciate it if, you guys want to learn more about jlc PCB and their capabilities, and, eventually. Order a board. Design and have them manufacture, it you can find a link to their website in the description below, I hope you guys enjoyed this factory tour I want to do a lot more of them this year so, leave, a comment below with what factories, you'd like me to go see and I'll see what I can do but. For now i'm scottie from strange parts if, you enjoyed this video hit that subscribe button down below and hit. That Bell icon next to it if you want to be notified about every video I upload but. For now stay, tuned for more adventures I'll see you next time.

This video is because of you! I went through all of the comments from the previous factory videos, and seeing inside a PCB factory was one of your top requests. So keep the suggestions coming! I'll try and make as many of them happen as I can.

i want to inside a battery factory

Strange Parts how about inside a factory where they make cases or enclosures for different electronic products. Since PCB has been covered already, it would make sense to look at the enclosure factory too, don't you think?

Very interesting. Great production process details. Thanks a lot for this upload.

You guys are dorks, just make love already!

Please visit a drone factory, thanks!

most insightful video since the iphone one :D

wonderful video again. pls keep going...

Communism ...

You're as happy as a kid in a toy shop!

What about ASML.. machines to make chips.

Asrock/Asus boards? Ancillary: How a circuit board designer does what they do. How, where, what, why.

I love myster Lyou

It seems that many electronics innovations were made in China since the 80s? Modern techniques and manufacturing machines that underlie any PCB nowadays. China doesn't get any credit on the innovation front so I guess it would be cool if you can talk about how electronics have come along and where the different innovations came from.

this is AWESOME!

Your video quality has skyrocketed, nice job, only thing i would criticize is that you should have informed yourself in detail about the manufacture steps, since lillys limited english wasnt able to explain it to us very well, other than that Hats off to jlc pcb

Last time it took 2 days to receive the package from them (EU). It's so cool.

It's cool to see things being made in China, how about finding a factory in the US that makes electrical components here so we can see the differences between how things are done in different parts of the world. I bet we are slower lol.

Absolutely love these videos, I designed some boards back in the 90s and getting one was a long wait and with no design checking, of course I messed up and the only solution was to hack with wire. You’ve really got to respect the whole manufacturing process these guys have..

thanks for making my request come true

I would love to see one of these medium or smaller electronics factories, from proto and setup to product - maybe like a production run of a smalltime smartphone or tablet - kinda like a clone factory, but something easier to facilitate.. (?)

So good, thank you!

Strange Parts i see u changed ur video style. Hope next u can use gimble camera rig for the moving shot. Nice

Intel's prosessor factory

His enthusiasm is what makes me click the videos!

Chetan A basically it's a QA machine

Ashish Rrr Yeah if I'm not mistaken jlcp does do complete PCB with components

TVs and Displays factories like TCL or Samsung or something. I'd be interested in watching that!

I’d love for you to show the process to reverse engineer a part to cad file for 3D printing. I’m currently looking into it for a discontinued car part and I’d love some sort of video of the process. If your interested Scotty, let me know!

Car assembling factory is pretty intresting. I got the chance to visit one in Hungary. But I am not sure how open they are for the camera.

Was this filmed on the 11th June by any chance? I had an order in production with JLCPCB at the time and I *think* I saw my board design for a couple of frames, but it's too quick to be sure... great video and awesome to see how they do it though.

Strange Parts Passive income online

did you sex her tho?

It was mostly me re-explaining things she said less concisely in segments we cut for time/clarity. Definitely something I need to work more on in the future for this type of video. I'm still learning how to make this part work well on camera...

Strange Parts How Lazer and other printers are made?

Can you saw us how TV's are made????

Yea

it's like.... all the info that the female rep could be giving us, he already took and is just repeating back to her.. yeah yeah yes yeah if you already know the all the info, why ask for the reps to tag along ?

Strange Parts And then towards the end the girl was like.... are you done seeing and talking everything? .. Now are you going to do the favor of asking me out already?? :|

I couldn't tell if you were explaining the concepts/steps to the lady, or if you were asking her questions in the form of a statement, or if you were verifying information that she told you in a segment that was cut. That was super weird. Cool video though.

Noah Leigh It's China. The first thing they try to do with waste is sell it. If they can get money off of it, they will. If no one wants it, they just throw it out. China "doesn't have" all the EPA laws that the rest of the civilized world does.

He's just a polite person, she was just agreeing to anything he was seeing, but that's why people are willing to open the doors of their factories to him, because he knows what the word "respect" means.

Really true.

I loved this! I had an idea of how circuit boards were made, but this style, this format, is both entertaining and informative. Moooooar!

An LCD factory would be cool to see.

Just amazing...

Strange Parts just amazing!! this is a really greatt huge video man! thanks for it!!

Come on try to into Qualcomm headquarters.

If you don't understand the process then ask her instead of asking your viewers. She is standing right next to you to answer your questions.

Strange parts i don't know you need that woman to explain but you were explaining to her as if you were working there.

A vacuum tube factory would be really cool.

Great job man!!! Now I'd like really would like to see a factory that makes DRAM chips (like the one you changed on your iPhone). We hear all days there is DRAM shortage, now let's also see how it's made! :D I know maybe this would be super hard since not many companies make it, but you have already made us dream with your videos showing what nobody else shows, so... Maybe hard, but definitely not impossible for you!

Strange Parts how about after the PCB'S on the motherboard what happens After the customer gets his products shipped.

Next time let her explain in Chinese language.. I kinda feel bad to her, for not able to explain properly about all of the process..

"I'm not sure how this process works, but I'm standing next to a couple of people who do... Anyways if you know how it works, please tell me in the comments below. Moving on..."

I posted this idea in your "Inside a Chinese 3D Printing Factory - in Shenzhen, China" video so I might have some credit in making this video come true too LOL. Next stop, try JD's or Ali's automated delivery sites please!

Big Thanks to you to make my wish come true. I have been using JLC's board for some time and it's quite amazing to see how they were actually born. JLC's staffs are quite cooperative and helpful throughout the production process. Recommended!

Let her speak jesus christ!

español :(

YAY!

Please GO TO a Pick and Place FACTORY!!

PCB Assembly video! I've been ordering PCBs from JLCPCB for awhile now, they're great! Shout out to Sophie Liang!

Yaqub Ilham oneplus 6 is made by Foxconn ;)

I just had a techno-orgasm! FANTASTIC VIDEO!

Whats the production rate of a factory like this?

Strange Parts I didn't see any such comments in your previous video,of course this is a sponsored video .

Great Video!

Now that we've had PCB's it would be interesting to see how actual components are made, from THT resistors to SMD IC's and everything between :)

Apple doesnt have a factory. it's completely outsourced to foxconn and company's alike. they won't let you into their factory thats for sure.

Scottie you need to pitch some content to TV stations. I coukid totally see you doing your own strange parts TV show.

anyone counted how often he said: got it ? - man i love your videos please do twitch live streams so i can support more

You should change to "This video is strange because of you!" :-)

Hi Scotty , thanks for d tour of the PCB factory, I didn't knew it had to go through that process

Modeltrain factory :)

Thanks mate, your enthusiasm seeps through - more of this style of vid pls!

Apple factory next plssss

dude i loved the continuity checking machine just epic manual is just so stone age compared to it

You videos are incredible! i found you through your Mumbai thief's market video and have been hooked since. Much love from Denmark!

please visit some solar panel factories bro

this video so large i forgot if talked about how they never confuse with different pcb designs in any stage of drilling naming etc

after watching it happen by hand so many times this automation scale is really interesting to see

i'm full thanks for the lunch

+Strange Parts Awesome channel with an even more awesome Logo design. Come far with no sponsors as far as I can tell. I think it would be great to show how various components, circuits, transistors gets put on boards of different types of electronics (Mobile Phones, Laptop, Monitors, Desktops, ect.). It would be cool to tour factories and how they build various electronics like Apple because you are so familiar their products but also other electronics (Mobile Phones, Laptop, Monitors, Desktops, ect.) and how they are designed and built. As well, I think it would be great If you could tour places like Xiaomi (Mi for short internationally) to see how they make electronics Xiaomi (Laptops, Charging Banks, CPU's), or ZTE (ZhongXing) in ShenZhen and see how they make Smartphones, or Huawei as well.

that was a great video, but here is a suggestion. even you sometimes have troubles understanding chinese people talking english right away, plus there is a lot of noise. so it would be great to see subs in your future videos

Its wonderfull to see you evolve from someone enthousiastic about a specific subject to becoming a true ambassador and fluent presenter of very complicated subjects.

i really enjoyed the video..please show us a factory tour video on flexible displays.. :-)

Thanks

I really enjoy your videos, not only are they incredibly entertaining, you're also a brilliant creator and you're so positive and genuinely kind. I look forward to your future videos! Thanks!!

thanks

Kg's of pressure?

I would be very interested to learn how these factories deal with the waste products that come from so many steps in the process! The alkaline baths, the solder mask, the fiberglass particles that get drilled off... What happens to all that material?

I appreciate your hardwork...& i am an electronics engineering student...i have seen all of your videos..all the videos that you have made are awsome..keep it up..with lots and lots of love and respect for you from india keep doing more and more nice videos brother

Awesome content as always. Love your vids. Congrats on 777k subs lol.

Hi, make a video of how various components are fitted on pcb.

smartphone factory would be great

Goddanm that was impressive.. The sheer scale of their operation is insane. Amazing video.

Or a mikrocontroller factory

I would love to see how Displays are made :) awesome videos btw

Untold amounts of passion coming from Scotty. Love it. Potential Youtuber of the year right here!

I am amased. This is another level documentary. Good job.Leveling up.

I love the smell of photoresist in the morning!

This is awesome! Thank you for sharing your experience with us! :)

Thanks you for this great videos. I didn't imagine that the process was so complex !

Its totally using I.Cs they will still use capacitors, resistors and diodes. This factory is fully automated.

I've ordered many pcbs for JLCPCB. Thank you for this video...

Nice business model you've worked out. Get factories to sponsor your trips. Good one.

i like how she just say yep yeah yep yep and his just explaning everything like his he knows everything then the girl is like why tf do you need me when you almost knows everything

No big brand makes the product themselves anymore.That includes the Laptop brands like toshiba, sony etc.All are contract manufactured.All that the brands do is marketing advertising and warehousing. Thats it.

A PCB, which is the heart of any electronic gadget is dirt cheap to produce. Maybe a couple of dollars at most.The most expensive part is the screen and battery. A mobile phone costs $ 10 to make. Really, its that cheap.

Electronic PCB making is a lot like Screen Printing. Im surprised they are using film for every blank pcb.I would've thought the laser is is doing the exposing part...but no, its still the positive film which is doing it.

Hi, I'm not a chemist but since I've worked in a PCB factory a while ago I know that they use a solution that has copper in it and it has positive electric charge and also they connect the pcb fiber glass part to negative electrodes so the tiny cooper particles in the soulution will bind to the pcb

As a retired PCB Engineer you got everything correct. I don't see any changes since I retired in 1985. Just more automation

Amazing piece of content.

Could you do the next step of the process? A factory that adds the components to the boards? Or maybe the step before, where you see an engineer design the boards?

Can you make a psp ?

Got my first PCB from JLCPCB yesterday, awesome quality und super fast delivery! Got a 4 Layer PCB within 6 days to germany :) This makes prototyping sooo much faster and cheaper for my company!

This is LETGIT

keep them coming

Ohh my god I love JLC PCB recently I received circuit boards and spare parts from JLC PCB..I am wondering about their service and product quality. 1000% of excellency in their works..Thank you so much dear for making such a video about JLC PCB.

excellent video, impressive factory.

Electric bike factoru :D ,

Wow this is amazing- thank you for getting a tour of this facility!! I'm blown away by the level of automation achieved by these factories, there are clearly some talented/hard working equipment engineers who are developing these processes. Such a cool a video :D

So we went there with our technologies, we built factories, taught them how to do it, turned our factories into warehouses, which we are now closing, as it becomes cheaper to ship directly.. and now they are teaching us technologies we.. forgot? Oh, no.. we didn't, she just pretends that she knows, he pretends that he's asking.. while he's explaining.. Man, I'm lost with it.

Your videos are so good....and the editing is getting better and better..

Lily is like: how do this guy know so much?

A well made video and a very interesting factory!

He is doing all the explanations. She just says yeah.

I used to work for an electronics manufacturing company a few years back. At the time all of our pcbs were purchased from companies in the US, however our purchasing department started outsourcing pcbs to companies in China. I can tell you from experience that there was no end of problems with quality of the stuff coming from China. - Starting with their lack of understanding of design standards. There seemed to be a lot of misinterpretation of basic manufacturing standards. I'm not referring to the actual engineering design that we would send them, but rather the manufacturing specs. - They always seemed to be on the low side of tolerances. Now that didn't always cause a problem but every once in a while it did create problems with designs that might have been borderline or with stack up. - They had very poor quality control standards. It seems their level of quality control depended upon what we insisted on. And when there was a problem, it was a hassle trying to deal with the factory do to the time difference. Hopefully things are different now.

That girl is so cute.

I get my hobby boards manufactured by this company. 4-6 days from submitting my files to delivery at my front door. And at US$0.20 cents per board. Fantastic service.

So does the factory use a licensed CAM 350 software? I am a Chinese, but infringing US's intellectual property isn't a proper business conduct.

another hole is for isolating high voltage.

Wait, I'm so confused who the host and who the guest is...

Felt like you were giving her the tour lmao

I am not sure how JLCPCB plates copper on their boards, but we've done this in our laboratory. Please research the process thoroughly if you attempt it, it uses toxic chemicals, especially formaldehyde. There are two steps: first electroless plating, then electroplating afterwards. I can explain how we electroless plate our 3-D printed parts. First they must be cleaned thoroughly, which for example can be done by using sodium hydroxide. Then the surface must be made hydrophilic by oxidation. We use hydrogen peroxide or sodium percarbonate for this, others use ammonium persulfate. Then we have to put a catalytic layer so that copper deposits on the surface. We use colloidal silver as our catalyst, which is deposited by alternately dipping in silver nitrate and tin (II) chloride. Then electroless plating is performed, with a mixture of EDTA as a chelator, triethanolamine as chelator and buffer, sodium hydroxide, copper sulfate, and formaldehyde as the reducing agent with the solution maintained at pH of 11 and at 50-60 C. Then the part is electroplated, which uses dissolved copper in an acidic solution, with copper sulfate, acetic acid, citric acid, and a few other chemicals that act to make the electroless deposition smoother, more even, and shinier. Then it is dipped in a protective solution like benzotriazole to prevent corrosion on the surface. The process we used is for an academic laboratory, so its likely JLCPCB's is more suited for mass production and not like the one I've described.

JLCPCB is doing a fantastic job. Delivering a quality product at a low cost. In emerging countries like mine, the lack of suppliers means that we are left without many options. Not long ago I made my printed circuit boards with pen and iron perchloride. Horrible results. After the easyEDA/jlcpcb I can even commercialize the boards that I designed. That's awesome.

You were on a tour with the person who worked there. Why would you ask us for something you didn't understand in the comment section at first rather than ask her? It's becoming more like you gave her a tour about the fabrication haha

She didn't know either, and Mr. Liu had left us to our own devices at that point.

Put copper in her hole xD

Nailed it. I went on a Shenzhen pcb factory tour last November. Strangely, they took us through in reverse and began with packaging, working backwards to file inspections. I have designed more than 400 different pcbs over the years and have seen tooling costs fall to about 15% of what they were in the early 80's. Mostly we now allow 5 days for manufacture and 5 days for freight, otherwise the price creeps up unnecessarily. Well done video. Great production values.

You know what I want to see... Solar Panels, or Batteries, to show how nasty that stuff is on the manufacturing side of things. Just so people realize it's not all sun and flowers powering their ride to Starbucks...

the best vias technique is still a big secret

youre like a louder, more intellectual Conan O'Brien

Thanks Again! I would also like to see some personal interviews as well. She did a great job of giving you a tour, but I'd like to hear stuff about where she learned English, what kind of business owners she deals with (good, or bad). Like the guy in Dubai with the antique cameras sharing his family history :)

When india have this?

I worked for 10 years at Burroughs/Unisys Corp. making PCBs in a plant in Carlsbad, CA (it is no longer there). Except for the enclosed high-tech aspects, it was basically the same exact steps back in 1979! We were more industrial in nature so only the Imaging Room (where the masks were created) were "clean-ish...had to wear smock & hair nets. A lot of the steps required hand-transporting rather than conveyor lines. We had a huge line to plate the Copper, Nickel, and Tin on the boards...the 700 line (The Baker Line)...huge gantries and computer controlled! Such great memories...thanks for the video! -) TQQdles™

*yeah*

This guy is a little hard to watch

Great video. Just Subscribed!

jlcpcb is the next squarespace. every tech youtuber is sponsored by them

the girl only know how to say "yaa" "hmmm" Is her ability to speak broken or something?

Right, but Americans, in general, speak no other languages. I'd be happy speaking broken Chinese!

you can see her getting less and less interested in doing this as he keeps yammering. started out laughing, ended up with ya, ya, and polite nods LOL he is annoying

pipi

Pretty much very awesome to see this, you are a lucky guy seeing this kind of manufacturing.

Solar Panels factory would be nice ! there a bunch near your location i think.

Amazing! just mind blowing Scotty ! i'm seeing how you work with your videos and edits, and pal, you are doing great work! loved the PCB factory

Yaaah!

Supert cool

Amazing - thanks a lot for this tour

*IN CHINA* "Why is it so yellow in here?"

It's UV light used to shine on the boards. So nothing at the blue end of the spectrum.

"Wow, wow, amazing, wow". Not for "dummies", for really dumbs.

Oh hell yes! PCB plants are amazing! Kind of like getting your drivers licence and a car, and suddenly having the ability to go literally anywhere, but for creatives, and the doors to potentially create anything have just been opened. It's that big a deal. Short turnaround PCB manufacturing is what is putting the makerscene on the forefront, and competing with turnkey. It's 2018 and there is literally no eason not to have anything in your life not custom, handbuilt, utilising your own hard earned knowledge.

He's like the Steve Irwin of How it's Made

Great video. I ordered 40 small PCBs (inc two designs) from them a month ago and took the cheapest delivery option. They took less than two weeks to get to me (UK) and cost less than £10 total delivered!

It's funny, I started designing simple PCB's to create a SLA printer from spare 3D printer parts, and projectors, so his last few vids (which I've watched in the last few hours!) have hit home. Lots of youtube 4 layer PCB vids digested :)

This video was quite the eye opener. I lost my job because it went to China.Because of my technical background, I can tell you do not understand electronic development nor the process of manufacture. Nor do you understandthe impact of sending thousands of jobs oversea to increase corporate profit.. The ultimate goal of any company or individual is profit. Some would say,yes, so what. That's the way the world works and always has. But, put yourself in my shoes. An exemplary employee, loosing my job, family, homeand belongings.    Let me educate you. The design files are not designed/conceived in China.Other countries oversea them. They do not ( yet ) have the design skills tocreate. Very insulting to see your joy in thousands of skilled job loss. HMMMMMaybe a huge tariff is justified, if you haven't earned your way.   I only read a few comments, but it was sickening to me. Everyone so happy,everyone who didn't earn their place in the conception or development process.Without the West handing you everything on a silver plater, you'd be sweepingstreets.   I know this because I was a victim of cooperate greed. Beware, companies will move their production anywhere it's cheaper. I was overly confident too.Rated #1 several times, but if the same thing can be done cheaper, elsewhere,they'll move it. From a business perspective, it's the right thing to do.    My suggestion to China or any other country is, save your money. They'll leaveyou in an instant if they can get it done cheaper elsewhere. But don't be sador disheartened, you did a good job. It's about money and those at the top.Governments aren't necessarily to blame either.    I was so sad to see many misplaced joy in the comments glorifying corporations who are abusing the Chinese workers. They already work for less than anybody else. Maybe worldwide unions are needed.

When and why did he start to speak so freaking loud? Generic Youtube behavior

No, loud factory. He'll learn to trust the mic levels. Like... Nascar announcers ;)

Dude talks too much and too loud and doesn't let cute Lilly get out more than a "yeah" before cutting her off. Man, slow down!

Can you get at Foxconn?

I always wonder how someone got the idea of how to make something (like this factory are making PCB), and also how they found a way to construct the machines and software that drives the factory. It's really cool

That poor girl didnt had a chance to say anything. Have some respect for Asian people. You are a quest, not the director ceo. You only watch , and keep your mouth shut.

Incredibly detailed and informative factory tour, this was so damn interesting! This was so professionally edited and produced i really start to love this channel :) big thanks for this again, amazing journey through the factory!

You are my best channel.

omg this dude it's so rude!

Wow! =O

It's looks like so unreal....these people are amazing...wonderful video

What's the point of having Lily just saying "yeah" all the time in the video?

looks like you all ready knew every tying and you were teaching the lady

If this company would make circuit boards for nad 3020 amplifiers,they will make a killing

Great video

Oh man, I used to work at a PCB factory in Shenzhen.

Go to a CPU manufacturing plant.

She totally had no idea what he was saying most of the time.

Edward: I think, she understand.

super vidéo !! next time a battery factory

Plss make your own mother board from scratch

Does your component fit Lilly's PCB?

You should have gone to a PCP factory. Would have gotten wild.

Please don't put your PP into weird machines.

I think it would be cool if he did a iPhone USB C conversation kit, kinda like the headphone jack mod. Don’t know how possible this is.

so awesome and thorough.

167 time Yia , but i am not sure i am right , Is there somebody can help me correct it ?

Love There

Is she giving you a tour or are you giving her a tour? Haha :D fascinating factory, great video, documentary level!

I imagine that the factory representative explains each step to the visitor, and then he repeats a more succinct version to camera, and that's the one we see.

cool vídeo thank you

The girl dont know wat they doing .... yah yah yaaaaah yah yaaah hmm damn

Why you know more info than her?

Lily needed an orgasm. I hope you obliged.

FoxConn

I have a suggestion for the next vid. Why dont you step back and let the company you visit explain how things work.

I love to know the names of the machines and where to buy them.

Nice open toe heels in a factory!

Do you speak english ? Yeah

This was amazing. I do agree with the rest of the comments! Keep up the good work! I love your channel!!!

Wow that's amazing!

thank you it's step by step, not 100% clear but it's more than usual!

Incredible video! Many thanks! Keep on doing these videos

This is why China is the next world power.

No big deal. I have worked with a CNC machine that can make a circuit board without this process. The machine was German made.

Only an idiot would say wow to that!

It doesn't make sense. Leo or in Chinese, the correct spelling would be lio. Leo is Lion in Latin and I don't know what Lion is in Chinese.

Let me guess, Foxcon?

nice video

YAH

Wow, really great video, it was really nice of then to allow you to visit the factory, I have always been curious as to how all these process worked... Now, about Lilly and some comments I've seen here, she is a really cute and kind girl, very caring, I bet she was there, more to tell him where to go or not go, than to do all the explanations, it's obvious that she understands the process, and she gets what he is talking about when she sometimes intervene to correct or complement him, or to just answer some question, so for all of you who thinks it's funny all the times she said "yeah", or when she tried to explain things and got a little stuck, try learning all this technical terms in mandarim, and then try your luck explaining all of it in a fast pace, while speaking in a language other then your own. Once again, really cool video dude.

Some things help me learn somethings because my knowledge is .......... or other are smarter than me

Great tour you gave the Chinese lady!

I always wished to work there

I only watched this to learn how to fill the vias...... and this idiot couldn't figure it out ???? :-)

Scotty: Motoring throughout the video.. Lily: Yeah...!!

While I was watching this video,there was a PCB manufatoring ad

Yeah.

would be interested to see an electric motor winding machine, a wave solderer, lcd screen production, anything about electronics production really, but especially the industrial machines which make the world (sorry people, you're cool too

Could you see about a tour of the DJI drone manufacturing facility in Szenchen?

GUY>BLAH BLAH BLAH. GIRL>YEAH YEAH YEAH.

Aw man we need to start learning chinese

I was surprised how many phases there was to make a PCB board!

I want more Lily for future videos

Man, let her talk!! Haha

Ela tá tão na sua! :3

You were so excited in this video! Great to see your enthusiasm!

"flying probe" not "flying poke" but very nice, thank you Scott

yea

Could you do a video on the tools and setup you have?

Take a shot evrytime she says yeah

Television is doomed it cant do this quality of content. Amazing.

Dude i love your videos, and the quality of the content/editing is rising up in every video that you upload. You should be fulltime youtuber. Keet up the good work!!! cheers from Chile!.

A really informative video, but it seemed as though you were giving her a tour instead of the other way round! Even though you know how the process works, you should have asked about each step and got a thorough and open-ended response.

Yeah! Yeah! é claro que ela ia responder isso ele ja falou tudo, chato... Deixa o funcionario explicar. Good video

awesome

Thank you so much for such a detailed factory tour. It was awesome !

Holy crap! This was amazing! Thank you for giving us a peak inside this other world!

They still use Windows XP for those machines

PROCESSOR MANUFACTURER FACTORY!!!!!

If I got dollar for every "yeah" they said in this video, I would be a millionaire.

Great tour and narrative. The budget for an infomercial is usually > $50k, these guys owe you big time! I've been to many electronics companies in China, have emails daily and conference calls several times a week. This video would be unwatchable and the narration unintelligible without Scotty. To all, not only did Scotty do a great job of narration, but organizing and editing. It's not that the Chinese do not have great English skills, but even in Chinese, the descriptions and explanations are very poor. While there are translators and narrators readily available, their usefulness in technical fields is equally poor. Scotty already knows how PCBs are made, which allowed him to make this great video. There are many schools in China, to teach English. They all insist on "native speakers", i.e. foreigners, for teachers. Chinese companies relying on exports should hire native speakers, very knowledgeable in the subject, to make their videos and manuals. It took the Japanese over 10 - 20 years to learn this and become the huge success "Japan Inc" became.

nicely done!

Sic video ....need a factory in England lol

This was just..... AMAZING!! Best video on youtube all year by far.

*SO WHATS GOING ON HERE??*

Any question Answer : yeah

I'm not a chemist but I've studied this process, Its known as electroless plating of copper wherein you use copper solution and a reducing agent, initially you drill holes in the PCB base and then carry out surface activation within the holes so that Cu2+ ions when reduced (reducing of Cu+2 is like giving electrons to the ions so that they convert to metallic form ) get deposited on the suface within the holes, surface activation is done by using Stannous chloride and palladium chloride or other agents, the base is dried and electroless plated, here the Cu+2 ions in the solution get reduced by the reducing agent and then the Copper atoms get deposited on the surface within the holes and form a thin layer thereby forming a connection between the two sides of the PCB.

Fantastic! Thanks to you and Jlpcb for giving us a peek into the technology used to make our PCBs.

Short conspect of the girl's speech: "Yeah :) Yeah! Yeah... Yeah >_< Yeah :C ....... Yeah. And here it ching chong ching chong ching chong. Yeah."

So interesting! Great stuff man. More like this!

I had used their service few dozens time. Cheap and good enough for me.

Syncing with the girl: yeah , yeah, yeah, yeah, yeah , yeah , yeah lets go ... yeah , yeah , yeah ,yeah , yeah , yeah , this is the room we have to cut it , yeah , yeah , yeah ,yeah hehehehehe yeah yeah yeah yeah uhhum when we go this machine this cut in pieces beacuae the edge is shapre we smooth it , we are going to see yeah, yeah , ueah , yeah ,yeah . Scooty : yeah

you lost me at the holes

amazing ... i will try order ...

Con los nuevos aranceles de Trump a China dificilmente veremos a un chino en una ensambladora estadounidense haciendo lo mismo que en el video.

Made in China! Great video.

Compliments to you Scotty! In a sort time such an awesome & growing channel! You are very polite and respectfull!! I think it was an good choice to travel in Asia, it looks like they are so much more in modern progression than the West. I would like to go there too in the (nearby) future! Maybe we'll ever meet up ;-) Enjoy your day!

... yer jobs, kiddies! - better hurry on up - those fries and 'hand-crafted' hamburgers are gettin' cold... ... ... Y'all can thank the 'hippies' and the 'hip' capitalist pigs in Das D'Strict Von Columbia for the big, American 'dream' give-away!

Why is this a-hole shouting

such a Bambi.. ya ya yah

Nice video, yah

I wonder who design / manufacture those machines in that factory , shown in the videos .

Oh i see

Thank you got making this video. I get my boards from them and I love them fast service and shipping.

what was up witht hte image quality at about 14 minutes? is it the lighting that made it look like vhs quality?

Fascinating! Enjoyed this very much. One little critique, I think maybe you talk a little to fast for them to understand you completely. :-)

looks like he knew more than her

72 times yeah yeah

Wow its so cheap to get stuff made here too, insane!

انهم بعملون بكل دقة وامانة وقناتك قناة رائعة استمر وفققك الله - احببت ان اكتب بالعربية للحفاظ على تنوع الثقافات

Rather than a factory, I'd love to see how the distribution and shipping asect of sending these phones overseas works. There's this russian guy that does tours of all the most important internet sellers of Chinese goods - Gearbest, DX, Pandawill - bur again his stuff is entirely in Russian. Also cool would be a look at what happens to your package while it's still in China, always wondered how that worked and sadly just the tracking just didn't do it for me.

Great video!

Scotty:Trump is the best president. Lily:Yeah ,Yeah.

yeah!

You brought that girl just to say YEAH? wtf...

Space x

I couldn’t believe my eyes, what a factory that is..

Yah

Drink every time she says YEAH...

Yeah!! Is the national word of china.

Lily: ya ya ya .. ya ya

I don´t want to be a hater, but I really don´t like the fact that you explain almost everything and the professional only says ¨Yeah¨. It should be the other way around, the one who knows about the subject should talk about it and you should say ¨yes¨ when you understand. It seems more like a forced prescripted conversation with interesting video footage from time to time instead of a fun to watch video with educational purpose.

Irritating presenter making a 'hey wow' video about printed circuit board manufacture. The camera operator does a good job.

The guide

Wow. Amazing. Great video too :)

Shot every time she says 'yeah'

Wow, great video, mind-blowing process in such a short time. Thank you!

where do India stand?

Yeah....

Did you two go on a date afterwards? Yes Chinese Girls are HOT! 14 years experience of a wonderful one!!! David and Lily and Katie.

Awesome, Amazing China, Fabulous, Hard workers of China, Thanks China for delivering Global demand & needs

And Donald thinks he can bring these jobs back home. Rising labor has turn 80% of their jobs to robotic automation. Think USA company can jump in and build these machines? These mechines are the result of million of hour of manual labor fine tunes experience. These are the machine that make the machine, musk wants.but to get there wasn’t stolen but 10+ generations of learning. Beside this is back bone of electronic that by product o in waste water would drive the epa nuts. .

Seriously good content. This company deserves more business for being so open about their process. Good on them!

they're fast and good for their price. can't complain anything at all!

Yeah

Yeah, yiah

she's super cute, love Lilly!

Wow this is fucking legit, I don't know where you learned to be a host but you're damn fine at it.

Hahaha... I feel you are the employee of the the company not the girl. She only know "yeah".

See how the US steals Chinese technology.

This was a freaking awesome episode!

I pray that we have a "shut off switch" for these plants in the event that we go to war with them.

Great video as always. This is some very interesting stuff! I'm currently in Shenzhen at the moment and I am pretty lost on where to go and where everything is. I was wondering if you could point me in the direction of specific places?

Come on man let her talk lol

Do you ever plan on releasing any more merch, or putting anything else up in the store? Would totally buy some

So this is where my job is gonna end up soon....lol

You have single handedly changed my entire perception of China and its people. Thank you. I would love to visit someday!

i felt like post modern ' how its work' video. its so great to see videos keep developing. Thank you sharing!

I came across this,while looking solution for my IPad. Its a universal charging board made specific for Iphone/iPad, I wonder how it'sgonna works. Maybe, Strange Parts can do some review on it. I got a few question for it; 1. Will it work? 2.If its Yes, does the charging symbol will shown up? 3. What was the actual price for 1pcs? ( it was 8.8$ -15$ on Alibaba website ). Thinking to get one for my iPad. Thanks in Advance.

clean. nice edit

Incredible videos, I'm so glad you took the time in your life to truly explore your interests. I'm even more glad that you shared it with us, this has been a great experience. I traveled to asia as a kid, and I traveled a lot of other places too, this really takes me back. Feel free to send me a message sometime fam :D

That was interesting, yeah!

Awesome

I used to work for infineon and this cleanroom looks horrible haha

The question is how do they handle toxic waste.

so.... could I make my own sticks of ram or ssd?

what about TSMC lol

I love you Lilly, but, oh my god. If I hear another "yeah" I'm gonna blow my brains out

yeah

Hey Scotty. First, congrats on the video, it is really interesting. It is amazing to see the scale those factories operate and their attention to details, it helps removing that image of "oh, it is made on china...". Please, go to a factory that produces screens, or any type, that would be really cool, or even better, to a factory that produces ASICs from FPGA designs! Your videos are amazing and really informative, keep up with the great work! Hope you are still over there when I come to visit Shenzhen again, it would be really amazing to talk with you in person. Cheers.

Did you get her Wechat then or no? She seems interested ;)

Lol you should've slowed down your English, clearly she can't fully keep up at all

I am impressed beyond my own comprehension. I used to be in the consumer electronics industry in the early 1970s and got invited by Sony to visit one of their factories. How much things have progressed in 40 odd years. When I used to make my own PCB boards with first an etch resist pen and then stencils I never thought things would become so advanced. Many thanks to JLCPCB

Outstanding video ! Great effort , thank you guys :)

I literally just ordered some pcbs from these guys lol

I understand that you would want to speak when she doesn't have the English required, but it was kinda awkward with you explaining everything as if you owned the factory.

"There are two kinds of holes...three kinds of holes...in a circuit board" looking awkwardly at her. Also its very nice that you explained to the people working there what they are actually making.

WTF! Couldn't you just talk to the camera instead of talking to her????!!! Yeah! Yeah! Next time talk to the camera and forget about asking her questions! Yeah? Yeah.

Is Lilly visiting the factory? Seems like the guy already knows everything, Lilly just confirms with "yeah" lul

This is one of the best video I ever seen! Amazing!

Тупая китаянка))) Чувак больше знает о технологии чем она))) Yeah!

Most stressful video I have ever watch. Yeah!

Truly amazing talent, skills, organization, innovation! Thanks for sharing!

This is just like that TV show "How its made" but way way better because it goes into more details and it has "Strange Parts" associated with it as well so of course its way better. WOW what a great video. I loved it and wanted to say thank you for sharing this with us.

"Why the heck is it so yellow in here?" Because you're surrounded by Asians HEE HEE HEEEEE

i think the guy who ask questions, knows more than "enginier girl".

go to a Ceramic resistor factory, I want to know more about the issues companies such as AVX, Murata or Kemet are facing!

This is where your Iphones come from, designed in California, manufactured to perfection by skilled Chinese engineers, and interviewed by a random American. Full circle :)

I can listen to her saying "PP" all day!!

I prefer your old method with a bit more casual feel to them, I don't mind this at all mind you, just a bit of personal preference Also do more of the wholesale or factory machines market in Yiwu, I'm trying to convince my parents to let me start my own business

Scotty: This is the zone of the fabric where they dismember people, right? Lilly: Yeah.

Great video but I wish you let your host speak more.

How many times did you "got it"?

ja That chinese starts sounding like german after a while... He actually knows a lot more than she does.

her level of english "ya" :D I'm pretty sure that she don't understand everything what is he talking

I like how they were so open to you as a visitor.I thought factories like this are strictly restricted for outside visitors ...anyway amazing video.Loved it scott

You did a very good job. It's like you were showing them. :P

Windows XP at 25:18

wow amazing tour

This video deserves suscription! Well done!

This is like willy wanka factory

seems like u gave her the tour dude.. u did much of the talking

Poor girl had to try and keep up with English being spoken at breakneck speed!!

Dude that's an awesome video thanks !

*YEAH*

This is the video I wanted to see. Thanks.

this is epic, thanks for showing us that :D

Having played around with NI Multisim and having made some PCBs by hand many years ago I'm no longer impressed by the fundamentals of PCB making but rather by the industrial machines that actually make them!

Wow, well done!. It's good to see where my PCBs come from. JLCPCB is such impressive factory.

voice was annoying

Dude took his geek pills this morning!

can't say other words... only wow...

I wish he didn't talk so loudly and just let her explain the processes

That Lilly is cute. Worth the watch.

That throw at 24:49 :D

Her Yeah hurts my ears!!!!!!

I see a Windows XP desktop background there. Makes sense, was a great OS and updating to the latest Win OS would cost way too much. Still use XP myself for programming EPROMs and debugging old tech. Great video, cool to see the process from start to finish.

This is actually where the death star is build. :D

why are Asian girls so bad lmaooo

have a look at the factory kids.. 1 employee for the entire drill room. manufacturing is not coming back to the US and the sooner you realize trump is full of shit, the better

No you are going to find out now! They are made without bare hands and that is good because the average bear isn't as smart as yogi the bear. The average is only slightly smarter than Winnie the poo. Now to why the a clean, which is what our star is in is yellow. Answer: It is not because the machine is color blind, it is because the photo sensitive coating wafers are color blind. OK, I am playing with your heads. You've got to understand British humor. Only John Clease and Her Majesty Queen Elisabeth, the queen of England. There are too many more Brits that would I get so tired listing them all by name it would take the rest of my life and then some.

I would love to see those PCBs get mounted with components in a factory. Like the machines that solder CPUs and other complex components as well as simple capacitors and are able to align them, that's gotta look awesome !!!

Would like to see something from a Graphics Card Factory

That YEAH YEAH breast less girls blown up my nerves

I would love to see more on DJI drone factory

I love it! You serve perfectly the subject!

Scotty, I am a Brit (design engineer) based in an FMCG factory in Shenzhen. We specialise in plastics, IM, Blow molding, and Brushes, as well as final assembly. If you would like to come for a tour (assuming my boss will sign off!) I would love to show you around.

Yeah yeah yeah yeah yeah............

That smarmy grin is on my screen AGAIN hell no

Impressive. I realize that you were probably translating or rephrasing the processes that she described, but it almost looked like you were giving her the tour in some parts.

The guy has more clue about the factory than Lily, but she's cute :>

Is it still a clean room if there is a giant hole in the wall to let the PCB sheets through it?

Her Engrish is awesome ...

Make a Nintendo switch

Yellow I see Green God Am Color Blind

Great video! Seeing the whole process from raw material right to the packaging is very informative.

I want to know what that hot Chinese Engineer is doing for dinner........

I see an american explaining to a chinese woman how the PCB's are made in her own factory XD

EPIC

Dude just keeps getting more and more excited. Lol

Looks like you were the boss showing her the ropes on her first day xD

Weird video. Why interact with anyone else at all if you are just going to explain everything yourself?

now I'm convince you're walter white lol

Wow. China is well ahead of the West now.

The 1st process, in order to get the copper to stick to fiber glass, it's all done chemically, with no electricity. You have to dip it in a series of chemicals, and the reaction is chemical electricity. it later goes to a different line where electricity is used to put copper through the holes. This is after the lamination, the routing of the board, and the holes are drilled. it was called the automated line, and we hooked computer board to a giant rack, and it was dipped into large tanks of fluid. One of the fluids was sulfuric acid. In the giant takes of sulfuric acid were copper anodes, or chunks of copper. Electricity was run through the tanks and the boards would rock back and forth, and after a few hours or so, it would have a shinny plate of copper on it. We also did nickel a lot. I probably left off some steps because I'm not an engineer, I only labored there. It was a very shitty, stinky job, and your Levi pants would have holes in them in no time flat, just from all the chemicals that were used.

I worked for a Plate shop in Utah back in the early 80's (Sperry Univac then Unisys) and worked in every single one of these stages. We had to change the drills by hand, and feed the computer a big paper ticker tape into an old fashioned computer that read the hole layout. We had one board that was 16 layers thick. Brings back a lot of memories.

Why did they let you do this video? They have little to gain but a lot more to lose in terms of IP and proprietary processes? I am guessing you gave them the raw video so they could make their own promotional video?

Mind blow , great factory

You can thank open-source software for the reduction in price and the increase in scale. But maybe next time you can take a look outside a factory at their waste water facility.... what...oh ... it's not there or not actually activated....

Really nice video. I order my PCBs here. Thanks for your great service.

Great Video!. Thank You :)

this was done in the US back in the 70 -80s i was part of it then, thanks to china it is there now thanks for putting people out of work

* ASKS QUESTION - YEAH

Cool BUT less ads please. Im a subscriber and believe you should earn money but calm down on the adverts.

You did a really good job presenting this video given the language barrier between yourself and the "co hosts".

I like how he starts by asking her questions about what's going on, then geeks out so much that he starts telling her what's going on. I wouldn't be able to contain myself, either.

Hello Scotty. If it's possible, could you visit a Photovoltaic Panel factory? Thanks and keep up the good work.

"Why the heck it is so yellow here" *Because it's China, duh*

Do they make PCB for machines that make PCB?

Annoying dude lectures the lady who's giving the tour the entire time and then gives extra thanks to the guy who wasn't really even in the video.

Next steps would definitely be SMT, DIP, and assembly. However, it's really difficult to close to these processes since you can almost see the finished goods, which is sometimes highly classified.

Electrical Engineer here. What a great video. Currently working for a start-up and we are doing a lot of prototype pcbs. We've ordered a LOT of JLCPCB pcbs over the last couple months. Great to see how this process is actually done. Really is amazing. I don't know how they can be so cheap and so fast. Amazing stuff.

What is the environmental impact of this all ? It must be kinda terrible

Let Lilly speak!

This actually was amazing.

very interesting video i never saw before even i'm technician

that girl is like she does not know anything and had been hired just a day before to say "yeah", "yeah" "oh yeah", " yeah"!!

Although PCB has been around for many many years, it is still part of China’s intellectual properties and trade secrets. Think China is a bit too generous; doubt US will show other people how it makes computer chips

How many yeah! is she goin to say??

Kapton tape all over the ceiling lights!

ya ya ya ya ya

the legend says she is still saying "yeah"

I just want you to know that your videos make my day! And no joke they inspire me when i feel like its just out of reach or too hard, i think of your videos! They give the energy to at least try. I hope your having a wonderful day!!

Scotty: a big THANK YOU!!! That was AWESOME! I am sure Lilly gave you behind the scenes schooling but thank you for 'translating' it in quick english; you really enhanced the amount of info about the whole system. Thanks to JLCPCB, Lilly and Mr. Liu!!!

the real question tho, did they bang?

Wonderful video, go for li-po batteries!

Drinking game, every time she says " yeah" you take a sip of beer.

Lily: Yeah

they probably just use electrolysis to copper plate the holes.

Got to make sure the copper gets in the holes.

Fantastic tour!

Easily one of the most under rated channels out there.. Appreciate all the hard work you're putting into these videos.

yyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyy 148 "yea"

21 videos, almost 800k subscribers. Nothing but pure quality content.

Can anyone see their projects being printed :D

she's cute!

There are a few parts that you might have wanted to re-shoot while on site, so your guide didn't look like you were teaching her ;) (you can tell the audience thing like we're idiots)

This video is truly brilliant. I enjoy, I learn, so I'm happy. Thanks

I love how shes not explaining anything, hes just figuring it out himself on the go

I have a idea dont know if its possible . But here it is could you add the ability on a Wi-Fi only iPad to get carrier connectivity or add a sd card or both. Or sd card compatibility on iphone or ipod ect

what a cute girl

Do you have any info about why so many large Chinese manufacturers are selling products on eBay? Many of them are from Shenzhen. They don't like to admit they are manufacturers, but after doing business with them several times, I can get them to admit they are the manufacturer. I have my own theory, but I'd sure like to discuss it with you.

Very cool!

It would be cool to see how ICs are made and the process of designing them

Always providing great content for me to show to my professor and show to the class. I appreciate everything you do, thank you for being so informative and I would love to see more videos of this educational nature. Watch every video

Hearing protection isn't invented yet, lol. Poor working

Amazing!! thank´s for this vid

Seems like a "very easy" industry to create a start-up ... LULz... so friggin complex...

so mesmerizing!

Обалдеть можно. Не думал что JLCPCB на столько разогнался

Electroplating is pretty simple really... You'll have an ionic solution, a copper electrode and the piece being plated. Apply a positive charge to the copper electrode, which strips electrons from the copper atoms and sends them into solution. A negative charge is applied to the part being plated, the copper ions move through the solution, attracted to the negative part, where they pick up the lost electrons and turn back to solid, elemental copper.

How many times she said "Yeah" in this video?

Et le journaleux, il ne pourrait pas laisser parler un peu la dame ?

GREAT

I assume Strange Parts got cancer and now he is trying to learn PCB manufacturing for easy money. I am cool with that as long as he keeps uploading.

video made by nobs for nobs, lots of errors and wrong informations

suddenly i thought i saw my pcb being manifactured, but it wasn't :(

I would love to see a mobile phone factory like Xiaomi or one of the brands that make cheap Android phones.

Wow he know everythink! Lilly is just there for say Yeah!

Please visit BYD factory!!!

Awesome video. This is what I wish Discovery channel was today! :-) Great job Scotty.

Hey Scotty, Please go to led light factory !!! BTW, this video was awesome and cleared a lot of doubts I had in my mind. Next time please mention the production size of the factory. For instance whether the factory is one of the biggest among all other factories producing the same product or is it medium or small. This factory seemed to be very big. Also please try to give an approximate amount of capital required to set up whatever factory you show and the amount of people working in the factory.

Its so cheap, for 10x10cm, 10 pcs, 2 layers, only cost RMB$50

In China women work in the tech fields and don't need help from any feminist dumb movement.

I just subscribed may I ask why are you in China?

He is a spy.

HOW IT'S MADE Channel. haha

Why are you keep asking her questions when you already know everything Lol

Sooo annoying to listen to, especially when the guy is telling the local tech how the stuff works, not the other way around. Better rename the vid to: "Factory visit for dummies by dummy"

штамповка ,

Worked doing this for a long time, funny that they have full cover suits but not face mask, or gloves to keep oils off print films :)

YEAH !!|

who is giving the tour here? what a nightmare for this women

As requested here is a suggestion for a place for a place to visit. The WowWee Robotics Factory.

Lady Yeah.

OMG that was such a good video.... All of your videos are amazing to be honest. You're one of the reasons why I subscribe to YouTube Red. I don't want commercials interrupting this eye candy of videos. Very good job of taking us inside that factory. It was awesome. Quality of the video and video editing is top notch. Excellent job my brother!

I've followed your channel for a while and really amazed by the quality of these videos. As a Chinese myself and I was hugely into hardware stuff, I ordered some sample PCBs from them years before. I never realized how fast and convenient they were before I went abroad. China is really a great place for any hardware enthusiasts. Like what I told to my friends, you can buy every electronic components you need in one building, which is not possible for any other countries, at least those I have been to.

The CN girl is cute.

Me in my broad Mancunian accent :- "Lily..... back to my hotel for a night of hardcore action and tons of bugle?" Lily :- "Yeah" Such a sweet girl....

awesome!

i dont understand do you live in china but from the us?

That woman was useless, the host just explained everything and she kept saying yeah

*YAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA*

You would expect a video as informative and of this production quality to be a TV documentary or something.

Conor McGregor Lol!

You deserve my like bruh

Gawd! I had to stop half way through - I can't stand the presenter pretending to know more than he does and the female company rep going, "yeah, yeah, yeah" to everything he says. Arrrggghhhh

My head explode

That's awesome. IC factory next? :)

I subscribed your channel because of this video. Thank you for your effort. More like this please. This is TV production quality stuff.

Go to the memory making factory next time

pretty sure I've had PCB's from this factory!! Really Great Episode!!! I've always wanted to know about multi layer PCB's. I make PCB's in house on a mill and seeing this makes me feel great as its so similar i just take way longer doing the steps...

Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah

We need a "Yeah" counter for Lilly

Китайці молодці, просто неймовірно за 24години, скільки технологічних машин, в нашій країні до такого років 20...відчуваю щоб бути в тренді і все розуміти, крім англійської вчити вже потрібно і китайську. Дякую!

you missed to show the shlami that shows up to rub and spit on it

i think you should be the guide because you already explain all lol \

Not his first rodeo "this is my favorite room in a ocb factory"

She's learning a lot on this tour. She'll be a much better tour guide her next time.

This was my dream .. To watch this happening Thanks man

I just love Scotty’s enthousiasm in this video

I like how you take the worker of the factory through a tour of their own factory, explaining the process to them.

1000 process

Like right out of a post modern futuristic industrial age revolution from 1895. This is amazing.

I REEALLY needed this video i wanted to see these made for EVER Thanks for the upoad!

I know it's on its death bed pretty much, but an optical media factory would be interesting. Or transistors, inductors, FET, any kind of similar component really.

YA YA YA YA YA

the only word that the chinese girl said is : YEAH!

If you get testimonials from places you've previously visited, (Example: a video gets over 100,000 views and the company says thanks because they got so many orders because of your visit), then it could be nice to mention that at the beginning of a new video before introducing the new topic. So, you could start off your video by saying such and such place said thanks and what not, then begin.

JLC? I did a bunch of prototyping with them 10 years ago LOL.

Awesome video, please keep making more!

TIL: raw PCBs are yellow

i wonder if lily single? how many times she said yeah? i'm thinking she saids YEAH OVER 100 TIMES IN THIS VIDEO?OR MORE.. scooty should work there

Those copper panels were lying outside in the sun, exposed under UV. This don’t make sense. What I miss?

incredible video!

Lilly says "yeah" 133 times xD

It takes weeks because they combine your design with other customers. 24h is just manufactuting time. Its actually quite slow. You can make single or double sided boards at home much quicker.

Who explains the production to whom?

24 hrs from order to product completion? No wonder companies from all over the world does its manufacturing in China.

I thought the Chinese lady was gonna do the tour and explain all the process to you

Camera lens

Strange parts she is replying only. Yes ya yes ya yes ya.

Really nice work! Thank you for taking the time to make videos like this; and they're very professionally done, as well. I've used JLCPCB for my last few projects and have been amazed by the quality and turn-around time. Great stuff!

How to do your job. *Yeah*

With the recent Trump tariffs and trade war with China, it's hard to imagine if US can really compete against Chinese manufacturing at scale. These guys are probably get paid at a fraction of the minimum wage in any state. Plus the efficiency from time of order to delivery. It normally takes a week or more to get such a quality product produced and delivered.

sir make more tour videos about mobile or tv parts industries so that we can gain more knowledge

The adventures of the-guy-who-comes-to-your-house-and-shows-how-your-oven-works and his yeah-companion

Why do u need safety rails, if u a moron then nobody needs u.

I would fill Lilly's holes

China rocks when it comes to technoligy love from pakistan

Go to battery and solar panels factory ..coz china produces most cheapest solar panels in the world which has revolutionized solar power

China is the most amazing country

pretty intresting to watch

We need a new hands on experiment

Robots with circuit boards testing other circuit boards.

Absolutely excellent video! As a CAM engineer in a PCB trading company it is amazing to see an enlightening documentary on the processes involved in making an ordinary PCB. Most hobbyist or even professional designers do not get the chance.

mauorrizze yeah

Not true, though Scotty talked most of the time. BUT: how long could you talk in Chinese?

Great video! Now we know how a PCB is made! Regards from Monterrey, Mexico!

"ya....mmmmm. yeah,..... yes!" :D anyway.... it's a very cool and interesting video! greetings from Nanjing

Conversation gone romantic at the end.

This is my favourite video on YouTube!

Scotty you are awesome. Its incredible to see all the infrastructure and complexity. Your explanation makes so much sense and cuts out all the crap. Keep it up. I truly enjoy seeing your effort and the kind of commitment you have to letting us see really exclusive stuff in our lifetime which we could only wish but be never able to actually see it. Truly inspiring. I let engineer friends and kids see this to really get a size of what the world is currently doing and what we are actually studying in engineering colleges in our home country.

Cool, it's my hometwon

You are giving her a tour, lol

"Let me just re-explain that more clearly"

翻译老是呀呀呀 能不能出个中文给我们不懂英文的人看看

thanks you engineer Liu for your input !

dude you nearly make that poor Chinese girl nearly nose bleed on consecutive English and from what i notice she froze kind a like in her mind ............. processing ......... translating to mandarin..... return...... translating back to english.....reply........aaa! error 404 abort ..... reply yhea ..... LOL ..... lol.... other hand nice video it give a for view of that is what's happening in the back end on how those pcb are made and most of us taking it for granted.

I ordered some boards once, the product itself is really great quality for sure. if needed something else on the future i will put my trust on they. The only downside was the shipping (Regular, not DHL). it took like a month to arrive (Spain). For an amateur is not worth taking costly shippings. But considering how cheap it was cant ask for more.

That girl looked uncomfortable. I don't know why, though.

I am jealous of you

The whole video I was wondering if the factory took North American orders.. thanks for the tour, and for making that connection available to the rest of us!

wowww wow wow thank you You are fantastic

I had no idea multi layer circut boards were a thing. So many step processes! Amazing

"There are two... three kinds of holes."

SP: Wanna go out? Lily: Yeah SP: Any idea where to eat? Lily: Yeah SP: Great! where do you suggest? Lily: Yeah

You seem really knowledgeable, but it would also be interesting to hear directly from the professionals. I wouldn't want to miss out on any cool facts they might have to share. ;)

Awesome vid, can you make a vid for an IC manufacturing, photolithography process

不用戴口罩跟安全眼镜吗

someone make a "Yah" remix

best, more videos like this one please!

Like a kid in a candystore :-D

I wonder why China claims that they are a developed country and still have people speaking very poor English in a company like this.

Led factory would be really cool to see how the tiny components are built.

I originally read the title as saying PCP instead of PCB

Amazing video! It would be great for a next video that you show a graphic o the whole process. Visual stuff. Great Job!!! Really enjoyed this video!

did any one count how many holes in the videos.the hole count.

Thanks for making interesting videos in interesting different places.

All those good-paying AMERICAN jobs lost to china. SAD!!!

What about touring a vinyl art toy factory?

its more like you show her around than the other way

Great video and thanks a lot of the knowledge you have provided about JLC PCB company but do you mind to go to Beijing for RIGOL HQ and show us their departments and management ?

nobody there that was a English speaker?Clearly doesnt understand 10 words in English

all these videos are amazing. Great you managed to get access to places like this

Amazed for who people creating that machine PCB, Just automatic

Wow, nice to see the chinese worker making PCBs having a face. 10/10 Now I'm sad that those same people are the targets of censoreship and prosecution.

Friend of my had a board printing factory in Sweden. Yeah he printed pirated pay-TV cards and went to jail, so the business kind of went bankrupt lol :D

Awesome video, was cool to see all the steps. Thanks for sharing :D

The company which is ran by country is much more advanced

I cloud activation lock bypass please . I have an Iphone 7 . please

I hope this doesn't sound weird.. but I LOVE PCBs!

I always wondered how plumbuses are made

Nice. Just show the PCB designs. No problem for the designer

Drink every time she says, "yeah".

Свяжите ему руки и заткните рот

Does Lilly do porn?

I have ordered there many times and it is really good quallity and service !! and within 5 days here in the nederlands :-)

Yeah. Yeah. Yeah. Yeah. Yeah. Yeah. Yeah.

This is one of your best videos yet, learned so much out of it ! Would love to get more behind the scene factory content :D

Great movie! Exactly today I've received my PCBs from JLCPCB :) Great company!

Nice walk through .I always wondered how those PCBs are made

Freaking great video!!!

ya

Nice video man. Thumbs up for JLCPCB ! You have a very clear voice, but it is like you are yelling all the time when presenting ?

Ya

Yeah! X100500))

Don’t let them take videos inside factor they going to steal your I p

You sounds like a master

i got confused to who is the guide?

_“Yeah...”_

yah

No. of "Yeah" in this video: 105

why do these chines guys look so confused?

Lily knows the process. She would have to in order to work there. The host is just better at explaining things in English. He generally got things right so she had to agree with him by saying "yeah."

thumbs up for the if you spotted that they are still using windows xp as the operating system for their machines

Battery manufacturing would be fun to watch Scotty

that's what 'PCB' stands for? ...i feel kinda dumb now.

*GREAT video BUT we don't need LOUD music coming on all the time*

Just let her speak. You interrupting her is so annoying... Besides that, nice video.

Omg stop touching all the things!!!

Tom Nowell yeah

I would like to see a baby oil factory. I'm curious to see how many babies it takes to make a bottle of baby oil?

Did somebody count how many times they've had to put on & off the "surgeon"-gear? :D great video !!

It was 4 times. 3 different rooms, but we shot in the first clean room two different days.

Just A Zombie69 yeah

gh all of the comments from the previous factory videos, and seeing inside a PCB factory was one of your top requests. So keep the suggestions

Awesome! Thanks!!!

wow 嘉立创

I counted 164 "Yar"(Yeah)! You're welcome! :-)

Ya...

*Yea*

%90 yeah %10 Q,A

And the made nuclear too.

Everytime he said wow I'm going to slap my face

This was a really good video thanks man

Inspiring and Educative

How do they connect vias in multilayer boards, between layers???

The video is very interesting, but... While looking at the video I asked me a few times, who guides whoom and who is the expert? You, or her? She seems to be a trainee?

You sound like you already know everything

Had no idea that HASL was done by dipping the board. That is harsh to the PCB.

Thank you for the video!!! Awesome!!!

WOW - this is crazy - you are cutting big sheets into smaller pieces. This is TOO fantastic for me ( I am only 5 years old)

This idiot is amazed by nothing more than glorified silk screening. Notice that most of the machines are robots, its menial labor. On top of this its nothing more than a company trying to drum up business.

Hey man, I dont mean to be a party pooper to everyone's comments but I suggest you delve deeper into chinese because I don't know if you notice but your guide doesn't really understand most of what you are talking about in english (reason? this is due to the fact that their listening skills aren't on par with us english speakers nor is their vocab) So she ends up saying "yeah yeah" Especially on the electronics side of things in china, you won't get much people understanding the technical terms unless they actually do went/studied abroad. This is common amongst ppl in china, they don't get much foreigners coming in to do youtube videos on em. You're doing good though. P.S. There are other companies in china , A LOT actually, where the PCB boards arrive in 1-2 days depending on where you live for just $10 USD and you receive 5 PCB boards. Source: Engineer student in China, just a foreigner doing his thing. I just really don't want you to be tricked/scammed in China, common thing for foreigners especially to the ones who aren't really proficient in chinese.

hes so excited the whole time, its great

he is very existed I would be too if I was there

Since you are in China. How about a tour of a fireworks factory

MOAR!!!

simply the level of sophistication of the factory is fantastic. I never imagined that my $ 2 PCB would work so hard. Excellent channel congratulations.

Awesome!!

Wao now you guy stilling technology from the chinese? GOOD SPY DOCUMENTARY GOOD LUCK WITH THAT JAJJAJAJAJA

Poor woman can't get a word in edge ways

Loved the video, Makes me think about the hard work people do to make tec and how we all take it sadly for granted. And what nice people.

How much dues he move his hands when he talks

in china I heard the YOUNG people EAT all the OLD people for better productivity ?

PCB is still promising.. I have contact PCB manufactures from JiangSu province of China. The salary of these PCB factory workers and engineers have doubled or tripled in 5-8 recent years to $1500 to $2500 monthly, in hot seasons, the salary could reach $3000 monthly. But the work strength is very tough, which needs highly concentrated in the tiny things and sacrifice lots of your personal time to do the work...

This is why Trump will fail bringing back production to the US. Nothing can beat Chinese.

She only answered Yah

Automated CNC factory

This video was great!

While I liked this, I don't understand why the tour guide was even there.

SO COO, BUT 85 % OF ELECTRONIC USERS COULD CARE LESS WHEE & HOW IT WAS BUILT.

You keep adding American style hype to your presentation. Chill out. Let her do most of the talking, after all, you are the guest.

Absolutely awesome doc. Very well put together. The equipment in that plant blows me away.

22.44 dude is playing with fire

This is like important moments of dating movie

Jialichuang is the best PCB demo board factory in the world.

The chinese girl learnt alot about PCB manufacturing that day

I am a bit surprised that these factories just let a dude with a camera (especially an american) come in and film their manufacturing process.

After looking at how much work goes into making pcb's, I'm surprised that they are so cheap.

I think GreatScott needs to see the factory

Tour guide's English is excellent but she keeps saying yeah. I was like, um this girl speaks english like my friend, he always keeps saying yes like every 20 seconds. I'm like, dude I know you're not deaf, you don't need to acknowledge me so much. Maybe it's because they were in a relatively noisy environment?

This was a genuinely amazing video. Such an interesting process

Жаль мне не удалось попасть на завод... Первая серия "Невидимый Мир Электроники" была бы еще интереснее...

it's look like you talk to fast :D

Yeah yeah yeah yeah WTF....

Thanks Scotty for the great video! I always appreciate your enthusiasm! Keep up the good work!

Yeah. Yeah. Yeah. Um, yeah. Yeah. Yeah, aha. Yah.

新近粉丝,哈哈

please add chimese language

I wish the guy didn't act so amazed and excited. Just do the tour, and explain.

Christ this guy is annoying

i have barely heard of lcpcb and they have big production now i know why it's so cheap

Scotty, dude, can you wave your hands a little bit more? I'm not quite sure what you mean with only one gesture per syllable. LOL. Fun tour. Yeah, massively complex manufacturing floor with intermingled boards. Crazy cool. Thanks.

Thanks for your video. One small detail: the Alkaline bath does not remove the copper (which has already been etched out in an acid bath) but removes the etch-resist film (you no longer need it) and to boot neutralizes remaining acid which was absorbed by the PCB base material and may later cause corrosion.

All women

A great video. You could be a tour guide anywhere.

It's propaganda you know,they need more customers.

国内中低端制造业感觉在走下坡路了,人才都跑去搞金融和IT,实业救国,呵呵

Strange Parts I made circuit boards on a small scale at my school when I was 13. The process was exactly the same but the "Chemical bath" we used could only do 4 boards at the same time, which wasn't bad for a class of 20. Education can be great in the uk

Yo, Scotty. There's a a bunch of cheap mechanical keyboards on the market that come from China. A lot of them seem to come from the same place. I'd like to see you find the big hub of Chinese mechanical keyboard producers.

This was an amazing tour video! It's like a super How It's Made video! I know you kinda took initiative in describing each step to make it easier to follow along since Lilly may not have been fast enough. You could see how at some points it felt as though she was getting tired of the tour, but she's professional, and kept her cool. What a fantastic factory. Top notch equipment, clean, organized. I hope you treated Lilly to dinner some time after this! I think she earned it!!

It's nice to see just how electronics are manufactured in China without any propaganda.

wow ! thanks for the video, this is incredible !

I feel like he was teaching her more about the process than she did

Omg i learned a lot!! Thanks so much for creating this video, i love it!!!!

PP? PPAP?

*yea*

Be careful about the timing, she's saying it takes 24hrs AFTER the PCB project gets to the production line... You on the other hand, are talking about the weeks it takes for all the process, since the submission of the project to the manufacturer offices, BEFORE it gets to the PCB manufacture line.

All this manual alignment explains why all my Chinese PCBs have poor alignment, between the solder mask and the copper on small vias... @StangeParts, you should go to an American factory to compare the quality, they usually have a much better alignment and quality, try to contact Laen on OshPark

I like how their standard suits are made for chinese sizes, and he looks like big daddy in a kids suit

omg let her talk lol

YAAAAAAAAH

嘉立创深度用户到此一游!

Wonder if Lilly gave a private tour of her place afterwards.

This would be a good video if it wasn't for that loud mouth yankie fuckwit. He makes me want to stab myself.

wow what an amazing process, one of my new favourite channels

very, very, veeeery good video my friend. I love it!

Ah.. great that you finally decided to show your girlfriend! You guys seem like a great couple.

very interesting! Please do more of this

Who was supposed to be saying “yeah” and who ended up saying it? The guy was just trying to be dominant and a big show off. Because she was a lady?

Wow!

Lol he’s giving her the tour

-Dude, even if she speaks bad inglish, - Let her do some talk !!! (then maybe we'd understand why you don't let her) (just some advice for your next factory tours, which would be more likeable then) (is this what fenimists mean with 'mansplaining' ?)

All this for £2 for 10 boards plus postage - I have ordered a couple of times using their software.

y a h y a h l e t s g o

The new how its made? honestly your an inspiration, i love you.

YEAH!

Good morning, the fucking guy talks.

你觉得在大陆还能做多久?工业转型升级是经济发展的必然过程,但是现在好像周边没有出现能真正接盘的的国家,越南太小,人才储备不够,印度修十年基建把发电量弄上去应该可以。

Gregory Crewdson 我是台灣人 之前在崑山做過PCB 不過說實話 PCB是重污染行業 利潤最近幾年還可以 但環保成本很高 晶圓製造和封測也是重污染 但因為毛利率是PCB五倍之多 所以環保成本幾乎可以忽略不計 投入一筆淨水設備 再污染的水排出來都幾乎可以飲用 但PCB不行 一套淨水設備下去 利潤就砍下大半 還不如做面板

How's it made 2.0

her english is painful to hear.

ha Fun,...i recommended to you this factory last week

PCP?

really amazing to think how involved this is!

I wish I had a penny for everytime she said Yeah.

I work in asembly Factory ;p

Lilly so cute

Awesome video, Scotty. Your enthusiasm is infectious.

Hey, we're gonna take a tour of this company.. she's our tour guide --- proceeds to talk for her through the entire thing. ..

Can you add a IR senser in Iphone?

I can't even begin to comprehend the amount of genius that went into producing these.

This video is epic !! Thank you !

I bet that,s the best BJ he ever had .

This is what happens when the guy does all the talk, the lady can only nodding along!

can anybody count how many "yeah" she said?

that guy is total 'useless' literally

It's awesome!

Video is great, but please don't scream. There are ways to make a voice over.

I doubt you'll get to read this, but please visit Shenzhen Zhaowei small electric geared motor factory. I'm not related, they just offered me a tour recently and I haven't been able to go. It would be nice to see how they make the small gears and wind the motors.

Yeah! Yeah! Yeah! Yeah! Yeah! Yeah! Yeah! Yeah! Yeah! Yeah! Yeah! Yeah! Yeah!

My pcb is in video :D

Wow, really? What are the chances? What timestamp does it appear at?

24 hour turn around!!!!!!!!!! WTF! Man.... We suck lol

did you smoke something ? you talking like you are on 200% speed.

Strange Parts enb

I've actually ordered PCBs from this company before. So cool to see where they were made! Thanks!

3 Holes? ( ͡° ͜ʖ ͡°)

Thank you for your shooting, I’m PCB sales people work close to 30 years, this factory machine look very new and high end for small lot quick turn sample shop. Your plant tour and process flow are very details presentation. Hope to see more others factory from you.

You appear extremely silly among those workers while speaking too much .. The video feels like you are begging them to interact with you..

Lily is so cute!

I have ordered pcbs from them, with great satisfaction.. awesome to see a tour through their factory.

Very very good

The Chinese used to make paper, PCB's seem like the modern version of that.

The "expert" knows only one English word - "Yeah".

So fucking weird :p It's like he's giving her the tour of her own factory o_O

lol

So much goes into making my phone... And this is just it's pcb!

YA

the lady spoke very little...should hav given more floor to talk...

so cringy watching u tell her how this place works. One time u had a question about the chemistry and even that was not directed to the guide but rather to the viewers...

iPhone manufacturing

Samsung display factory

A injection molding machine manufacturer

who is more enthusiastic: linus tech tips or strange parts?

thank you for sharing!

So this all used to happen in USA. Before it got outsourced

amazing..

When Lily met DJ Khaled. DJ Khaled : another one Lily : yeah DJ Khaled : another one Lily : yeah DJ Khaled : another one Lily : yeah DJ Khaled : another one Lily : yeah DJ Khaled : gime another one Lily : yeah DJ Khaled : another one Lily : yeah

i dont like you

That's laughable he narrated everything instead of her

I enjoyed this tour. Good job!

I hope wahyu will answer this.

please make video about cheap CNC milling service in chinese

great video, i did love it :)

American tec gone to China

JLC is pretty famous for those who want DIY some small things especially in China. They also sold chips such as micro controllers or sensors. All the process can be done via internet. Customers just need to submit the circuit design file and the list of chips. Wait for several days as the product will be delivered through express. Pretty awesome company, and give chances for students in university to start their own project as the price is always reasonable. They helped me a lot when I was in university.

Ya, ya, ya ya, ya ya ya ya

Thank you JLCPCB for allowing us an insight into your awesome factory!

let the lady talk geez..

Wahyu Eko Romadhon gan maksudnya desain pcb kamu ada di video atau gimana?

dextersumsaltube nope, I know his nationality by his name, and this is how we say in Indonesian (literally translated to english). But let’s see.

Sorry, its not IMO, "my pcb" term used is quite exaggerated and senseless for pcb brand and for entire video.Its a very literal statement that he has his own pcb prototype in the video.:)

He means that he uses this pcb brand and he loves it, so he says “my pcb”

Dude she was totally into you. Hope you took her home ;)

That was WAY too interesting. Like candy for techies. I've always liked watching tech documentaries and seeing the process of how stuff is made. It's just amazing just seeing all the specialized equipment on such a large scale. I did wish you asked where/how the equipment is made and maintained though. Next time tour a factory that makes factory/assembly belt equipment, lol.

Killer video! It's too bad you had to mansplain most of the process to the company rep, but it's understandable as her English was not as good as yours.

Ya ya , yaaa

Ya! XD

Lmao. Are we sure the Chinese arent robots?

Well hats off to her.... she doing a very good job in those long heels!!!

I'd like to know how they keep track of the orders, i dont see any markings on the big sheets

I love this guy!!! Like an average dude that asks questions and searches for what I think about doing everyday

scotty:blablablablabla lilly: yeah scotty:blablablablabla lilly: yeah

i think you need to do another build

ohhhh yeahhhh....yeahhh....yeahhhh..

wow what a sexy woman you found for a guide .. but also .. such an interesting video ..

我竟然通过这个老外的视频见到了复杂PCB的制造过程

It's annoying. Looks like He was givia tour to those chinese.

she's not giving you tour, but it's you LOL :v

I think this guy knows more than her. All she says is Yeah. We actually don't need her.

Wow......what a complex facilities there!!!!! what a thorough process and hi-tech machine and system. Mind blowing...........very educated. tnx.

thanks scotty

Wow, this 26 minutes is worth for a electronics bobbyist. Really enjoyed it. Nice documentary.

Sooo interestting

So awesome, I can speak Chinese too, any chance to capture some of those engineers would say in their native tongue and have it subtitled in the next factory tour, this is some great down to earth documentary style video, this channel is going to blow up bigger than it already is it's not funny, thank you for your work Strange Parts.

Whats your name? "Yeah"

she is so cute :v

I'm only here because I read PCP

Mansplaining to it's extreme.

Great vid

Mei Ling good Talk english and shaking head all time. Make Love sucky sucky Long only 5 dollar

XIAOMI FACTORY IF YOU CAN OR WHERE THEY MANUFACTURE BULK PHONES

an impressive charming guy

I went through the process of touching the volume slider every time that crappy tune started playing.

Interesting tour but the looks on the two Chinese guides faces said it all at the end - "go home now please overexcitable loud American man"

This video is really great.

Awesome video, really interesting! Especially since I work at an electronics production company where they purchase the PCBs and perform all the followup steps like placing the components etc. :)

I order a lot of PCBs from these guys, great to see how they do it :)

I would like to see different colors on PCBs. Black looks very cool.

I will be excited as well but PCB's factory is making a huge impact on him. hahaha. Lucky to be there and well educated. It looks like he is working over there.

It was always my dream to see all these PCB and machines in ACTION. Thanks a million buddy!!

I've been using JLC PCB prototyping for a couple of years for my personal electronic prototypes. And I just watching them from a tiny start to nowadays, they advertised on forums and gathered their first group of internet users (including me) and then they kept on going to make the prototyping cheaper but also improved quality. They also developed their own software systems to make the process easy for customers. Now, all that you do, is to export your design and upload to their online system, and then waiting for 3 or 5 days to receive your boards. It's them that make a personal electronics activities possible!

take a shot everytime she says 'yeah'

I love this video so much thank you ♥ can you make a video on Arduino factory ?

the weird process explained simple: on the laminate (the prepreg with the copper layer on it) it is applied a layer of substance that is UV reacting but also acid resisting and after that the photo tool (the transparent layer with the circuit printed on it) is applied near the surface of the laminate and the laminate is exposed to UV light. The UV is basically chemically changing the substance layer except the areas shadowed by the photo-tool. The areas exposed to UV light are not anymore acid resistant and these areas will be washed away together with the copper under it when the boards are immersed/bathed in acid. What remains are the circuits. Because that substance is so darn sensitive to the UV light is the reason why you will see entire areas in a PCB factory with yellow light. The process it is repeated for each layer of circuits - hence also the name of the PCB: 2 layers, 3 layers, .. 24 layers. Basically saying how many layers of circuits are in the PCB. Bonus: Now you know how to choose a cheap but effective pair of sunglasses. If it has YELLOW or ORANGE tinted lenses for sure it is UV proof. If the lenses are blue or gray without a real certificate of the sunglasses I would not wear them even if they are an Oakley pair.

I think the hype is to see what really happen in a PCB factory. Almost every electronic assy designer know how the PCB it is made but not too many of them have seen also the factories where are made. Also the PCB factories are really impressive in size. In 5 years of audits I have never seen anything in Europe close to a half in size to the Chinese ones.

Where is all the machinery they have designed? A Chinese company or ?

amazing factory and can't wait to receive my PCBs i've ordered. Just to think they're running through the factory as I type :D

I want to fill Lilly's holes too.

I live in Switzerland, last month I ordered some pcbs from jlc on a thursday and I had them on the wednesday after. That is 6 days including shipping! Just insane.

I know a factory is kinda loud, but if anyone was to enjoy a video of someone constantly yelling, you should have hired Gilbert Gottfried. :P

excelente!!!

Ok go id หลาย

นี้แหนะกำลังส่นใจการเขียนพิมม์เขียว pcb พึ่งว่างจ้ะ เอาจริงสนมากๆเลย หึๆเร็วแน่หื่น เยี๊ยะ เร็ดโกเถาะ อ่า เยี๊ยะ

Nói gì thế??

Where was the soldering part?

YEAH...YES...

Please visit a battery factory, headphones/earphones factory, speaker factory, or softgoods factory (backpacks, bags, etc). Thanks!

now we know where all the excess "PP" goes into. The room with the yellow lights :D

I love how efficient china is and all their machines and ideas. They are great people.

Tnx it was wonderful

You should visit good ol midwestern state iowa. We have Emerson and fishers control where they make valves for nuclear plants all the way to just water valves and pipes etc. maybe take a look?

It was really cool!

someone is gonna have your beard hairs in their PCBs!

Yaaaah

24h is for manufacturing not including preparation that is before that after you submit. Don't dream about having 24h PCBs with silk screens and all :D She meant manufacturing only.

The chinese girl so cute i want her

You let foreign spy into factory. Now all secret go to USA.

I worked at a PCB factory here Just outside Richmond Virginia, It was the Largest PCB manufacturing plant in the world at one time, built owned and operated BY AT&T Western Electric. NAFTA resulted in it being sold and every machine and UNIX software being shipped to China. I operated and or repaired many of the same machines pictured here. Went to work for them in 1974 factory was closed in 2001. Many people lost their jobs to China.

Amazing! Great Video man! Awesome!

that testing machine....

waving your hands too close to peoples faces...

This is really amazing. Thx for taking your time at each production phase.

after 5 min I couldn't listen to him anymore

Completely skipped the step of etching after bonding the middle layer/s to the copper outer. I would assume it is identical process as the etching of the middle layers.

Now can you tour Tesla? Maybe you can tell them how they build their cars! I'll bet she was so glad to see you leave! lol

rad video! those machines are incredible

Drink Every Time when she says yheaaaaaaa

Lily's got a nice smile and cute laugh.

Funny it use to be eastern's going to west to learn about tech, and now the table has turned and westerns are going to east to learn... By the way, this guys is a arrogant thing that ignores all messages and emails and comments...

She is a factory itself of """YEAH""". ,

I died everytime you touched the boards without gloves and going inside cleaning rooms and not having beard cover.

GET THIS MAN A SHOW ON DISCOVERY CHANNEL!!!!

OR NETFLIX

David Kalbo I don’t want to die of alcohol poisoning lmao

poor workers wondering what is he saying? while looking agreeably nonchalant.

I built circuit boards for 20 years before it all went to China. This was a good presentation. However, you skipped over the plating of tin to protect the outer layer circuits and through holes during the final copper etching process. This entire procedure is exactly the same as we used thirty years ago. We built many thousands of boards for the likes of companies such a Ford, GM, Chrysler, Kodak, Zenith, RCA, USA Army and Navy and many others. Was a great business.

We pioneered many of the processes such as hot air solder leveling, UV resists, tin plating for secondary etching and other.

Mansplaining explained

Seems like a lot of work for $2.

Not sure why she was in this video.

so many processes, so much investment. Is 3D printing going to replace all this soon?

Lilly "Yeah" counter : 169

Excellent, short and simplified. Do Foxconn, I doubt they'll let you in, but at least I wanted to suggest it

Cool i should have to work in Chine cuze im quality controller work love that tech Weldone Chine people

-are you stupid? -yeahh yeahh

Nice video! Impressive factory

Hi This video is incredible. I would like to see a video abut those engineers who design those machines or robots and how they building it that make all this possible. thanks a lot.

How the hell do they line up everything?

They let you in but i don't think west manufacturers would let you into this kind of factory

oooo dude it is veeeeeerrrrrryyyy amazinge keep it up.......................

wow

So in plating, the Plated through holes go through a chemical process that deposits thin layers of palladium in the holes and over the board. Then they go through a copper plate cycle called a "flash" to deposit a thin layer of copper through the holes before putting an image to deposit thicker layers of copper per requirements

does this women know this process or not....

*this video is sponsored by JLC PCB*

"Yeah..."

Strange Parts, Thanks for the time and video. Just received and started soldering to one of the 10 boards I got from them. As luck would have it, I watched this video, then a week later I needed boards made..... give you one guess who the first manufacture was. Good pricing, fair shipping and less than a week from click to delivery. Please do keep videos on good vendors coming!!

One suggestion, come to think of it.... a good, low cost alternative to mouser of Digi-key would be great. Boards were reasonable, items to make up 2 were upwards of $100USD.

Great vid right up to the point of forcing a fucking AD down our throats! Fail. Thumbs down.

I have used them before and the PCBs were excellent quality and shipping was really fast. I am working on another design that I plan on sending to them.

great knowledge ..thx man..keep it up.

boring information video

Wow what a great video

Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah Yeah

Absolutely fascinating! :)

Western worlds have outsourced all the technique of making circuit boards to, how would I put it, cheap labour countries and in a way have also moved the knowhow on making these things to their craftsmen. :)

wow, you should really not touch the Pre-preg without proper protection. its infused with epoxy resin. Which is about as toxic as it gets. there is no telling if you get epoxy eczema from touching it once or touching it 100 times.

Great vid, I love the enthusiasm. Dude, so did you seal the deal with that technician chick or what? She liked you man, hope you got'er done.

You were kinda freaking them out with the constant sudden hand movements.

I guess that was the deal, he can make video under condition: you take this "yeah" girl with you :)

Her handler there is creepy...

She's smart and cute and beautiful. And the factory is amazing, I already bookmarked their website. Thanks to both of you for the awesome video!

china is an extremely censored society, free peech is not allowed the people are forced to be robots

it seemed like u knew more then her lol and she works there :P

oh that is you lily? actualy i talnk to you when i make PCB hahaha

americans are so insecure.....blablabla..i know this and also that..i know i know...

Oh, really a superb video, thanks!!!

Way to be rude to the expert and talk over her the entire time.

yeah yeah yeah yeah yeah yeahyeah yeah yeah yeah yeah yeahyeah yeah yeah yeah yeah yeahyeah yeah yeah yeah yeah yeahyeah yeah yeah yeah yeah yeah

the peepee increases binding force.... dirty asians....

Next factory should be a screen factory

Judging by their facial expressions, they think you are an idiot....................I dont think they are far wrong.

Y E A H x 100000000000000000 = stuff

you talk a lot lol.

PCB ?

..its the other way around.. he was touring HER in HER OWN factory.. x/

cool

man making too much noise

My dream job is to work in PCB factory as design engineer !!

The only important thing we're doing here is that we're putting copper in the holes... Lily: hehe;)

Just YEAH

yeah.

Love JLC PCB. Never been disappointed with the boards they make. Seeed would be a cool place to see.

Yea--"OH! I see."

Love your videos, though I feel like this one is a little too.... forced? Other videos feel more natural while this feels very scripted and had to do each take 10 times to get the right one rather than a few or just 1. Still loved it though.

The $2 seems just a propaganda, as to high quantity of PCB production, pcbway is more cheaper.

Wt ya ya ya

Because of your video, I just had a try to their service and wanted to compare with my original PCB manufacturer (pcbway), which I have been using for more than 3 years. I have tried many other manufacturers on the way. Some of them are cheaper than pcbway, but pcbway's comprehensive service really makes me feel relieved. I have already placed an pcb and stencil order on jlcpcb. the pcb is good,but the stencil seems too thin, and their service rep's English communication needs to be improved, lack of professional customer service. I hope that you can also list what are the pro's and cons of pcbway and jlcpcb. Thanks.

Jeez Dude, what is wrong with you in this video ?? You're chattering madly like a Meth addict :-(

Any guys know about PCBWay?

Yah yah yah

Lasse dort Platinen fertigen und bin sehr zufrieden! Absolut top Qualität, schnelle Produktion und Lieferung!

Ya... Ya.. .. Ya Ya.. .....?... Ya..

10/10

chinees are laborious

Why do so many Americans sound like Muppets?

Wow, I have never seen one of your videos and haven't learned 15 different things. You take your time, you bring enough experience, and a lot of curiosity. Well done and please keep doing what you are doing so well!

I'm mind boggled that he asks the viewers to explain the chemical processing when the person who can explain it is right next to him. Ok let's say she can't explain it, surely the company will have someone there who could... Also it is not copper wires, it's copper tracks. Great and informative video otherwise.

Holy crap

The process looks like screen printing! Nice work.

Ухх и клево же )) половину правда пришлось додумывать, ибо не понял.. Но супер!!

Lol

Nice video.....DHL ended up getting some publicity too

Take a shot everytime she says yeah

Are there plans to make the machines smaller. Why are the hardware machines so big ? The circuit boards look very big. Why so big, why not micro sized or nano sized ? Since ai can now assemble it all ? Could that factory be turned in a tiny room ? Why is drill machine so big ? The holes in circuit board are too big. Circuit boards should be micro sized. What a waste of copper. That circuit board should be way smaller. What is the board for ?

Fascinating, thank you

Very curious, why did you turn your nose up at a charcoal mask?

I love your videos man and you are really cool, but just my opinion that girl was really nice. I think she might have gotten a little bit annoyed with you talking and telling her stuff that she is trying to express (which seems to be a little hard not fully fluent in english). I know you are basically telling the audience and the camera and not her but she seemed to feel a little akward at times when she kinnnndaaa was interrupted or talked over. Not trying to make it sound like this is a huge deal or that its really bad or anything but wanted to bring it up since I really love your videos and the topics you chose.

the girl on 8:30 is really a robot

Great

Wow. I just stick a bunch of resistors into a cardboard sheet and solder it into a bloody mess.

CNN should give this guy his own show, similar to Anthony bourdains (rip) Parts unknown but about Technology

I thought the thumb nail was Conor McGregor. Was thinking WTF is he doing with CBs, like how are they ever going to help him beat Khabib.

everytime you fast foward you will notice lily saying "yeah"

Monologue et frustration !!!

He reminds me of Conan O'Brien Did you See Lily roll her eyes at one stage heh Good video though

This guy gave himself a great tour! They should hire him and fire Lilly. He knows much more about their process.

Where were the machine that make the PCBs designed and manufactured?

wow, that is crazy... so complex,

This is awesome!!. Congratulations!! and show us more great videos like this one. Regards from Bolivia.

yeah..............! yeah............! yeah...........!

1:21 your girl?

2:57 quien no sería feliz con un almacén de baquelita :)

god damn that girls cute

Thank you for posting this. I was always curious how mass production is done compared to small batches. Many years ago, I made PCBs on a small scale (mostly prototypes so companies could test before mass production in china) and besides the original CAM files, drilling and routing, everything else done manually - making copies of the film so instead of black it would be transparent, manually lining up the exposures, etching, etc. so it was quite time consuming and easy to mess up. Still, every step seems to be exactly the same with more automation.

That wall pass at 7:06 sure looks safe....

Damn....

In the thumbnail you looked like walter white from breaking bad in his meth lab.

Many thanks to Strange Parts and JLCPCB for this very interesting visit.

i wish you put the steps names, description and part names on every single stage... that was going to be really helpful and informative instead of just talking because i missed i cannot follow like this but thank you did great job overall

what a great video, respect to the company for giving you permission to have a look at the process

This factory is amazing. I don't think manufacturing is coming back to America :-(

Thank you ever so much for this video I am a techmaker from DRC, i have enought problems with pcb prototyping so i need your help give the contact of the pcb factory so i can contact them for service

The gal looked so nervous cause she was not confident with her English…Yeah

24:53 The guy on the right is contain your excitement Lv99.

Now she knows how PCB are made... If you need to yell, you need hearing protection.

Lilly hot

this is why chaina is called "WORLDS FACTORY"...!!!

you are really doing nice job....Keep it up..share more vedios like this....

Yeah.It looks he's giving her a tour with her being the guest :))

He looks like Peter mekennon in tumbnail

She's thinking, "Whew! What a long day. Are all Westerners this intense?"

If you like guys who shout everything, and are interested in PCB fabrication, this video doesn't disappoint.

very nice video thanks! :) The girl just say yeah! :) You do everything by yourself ;)

you overdose bass

"Ja, ja, ja, ja"

why motherboard have different color green, red, blue and etc?.. it is same material or have spacial each color?

min 8:48 that chair lol

Here we manufacture yeah’s

I ordered my PCB on this factory and i have got in less than a week,awesome, pretty good quality and so cheaper.they are the best.

Thank you for this video China is amazing....

blablabla bla bla blablabla?? ... yeea

I think I saw my PCB order on the conveyor , so I'm glad I got a glimpse of it being made. Just kidding.

china is on the path to destroy america on all fronts of manufacturing and this guy is helping them.

Nice Tour

In some room we can imagine the amount of toxic chemicals used, we don't taste the smell of epoxy and other toxic vapors, and what's happen to waste waters coming out this kind of factory ? And now we understand why PCB are so hard to recycle at the end.

Spam advertising

Hi it was an awesome video, next time visit any cement Plant.

Yeah.....yeah...yeah

You should let the girl explain instead of you yelling like a moron.

SJW would say "he is man explaining to her"

This was awesome

祝祖国繁荣昌盛

Seems to me you were giving her the tour, LOL!

PP

You should have gave her a separate microphone

Yaa

11:46 , The look on her face when he said "Now we need to drill some holes" . She may not have understood but her reaction is priceless :D

You kinda look like Walter white in the thumbnail

i thought it's pakistan cricket board

Loved almost all your videos :)

I feel like she learnt more from you... LOL!

the lady has waaaay to much patience. and the guy is like some nazi xeophobic piece of s**t on speed

I like seeing how excited he is about the manufacturing process that is going on. I just happened across this video as I was looking at JLCPCB to do some prototype hobby boards and it's nice to see the factory where I'm sending my design.

Scotty: *says literally anything* Lilly: "Yeah"

Very rude to basically not let her say anything else than "Yeah".

What a flirt lol

i was so impressed with this tour.Also how they manufactured pcb boards

I need a whole year without the word "yeah".

Holy .F. AMAZING .THANKS

YAH.

YEAH, YEAH, YEAH , YEAH, .... LOLL

Now I know why my boards are late...

It seems there are more female workers than male. I am kind of curious about the situation in other countries.

Muchas gracias por mostramos la fábrica, yo envió a esa empresa a fabricar mis PCBs. y los hacen muy bien. Un cordial saludo Eduardo Caporale, desde Mar del Plata, Argentina. ………………………… Thank you very much for showing the factory, I sent that company to manufacture my PCBs. and they do them very well. A warm greeting Eduardo Caporale, from Mar del Plata, Argentina.

Very interesting ,great vid

Great job, keep it up

The lighting is similar to the "safelight" we used to use in photo dark rooms. Either red or yellow in color.

A lot of people now using digital photography may not know that photos of yester years undergo a similar process.

Please show us a manufacturer populating the boards with components.

As I watch this I cant't help but think how much USA manufacturers and labor unions missed the boat.

Wow, 24 hours! That factory is amazing.

All this video is about "yaah yaa yaah ya yaaaah yes yaah yaaa yeaah"

Great video man.

Hey Scott, If you really need to explain everything yourself, then better keep your face to the camera not to the lady.. This way she won't feel like "Dude you already knows better then me" and can equally add up her comments in between if required and the viewers too will have a feeling that she has already explained you everything and now you are conveying it to us in your own words. WIN WIN for everybody right....!! looks like she is feeling LESS already...

Madam engineer doesn't seems like she knows her stuff...

pff is best MSI headquarter and factory tour

amazing, i can not imagine how many steps, and the complexity of the factory, to make PCBs, thank you for these video.

JLCPCB has a new CEO

Lilly = yeah machine

Thay did all this within 24 Hours ! That the Power of China ! Hats off to China !

Amazing tour - enjoyed it and well done Scotty !

Nice

You can't compete with this. I'm very impressed by the amount of automatisation.

If the tour was conducted in Chinese he be the one who is going yea yea yea, mm mm. lol

Just opened the Magix Video Deluxe new Release and seen your smily face on the start screen - lol - seems like you are everywhere now ^^

Thanks for the Great Educational tour.

wow that's wonderful.

ya ya ya ☺️

Where's the room where the copy the intellectual property?

Reminds me of Pink Flyod's Another Brick In The Wall

_got it_

He's more like the tour guide than the tour guide..haha great video

Greate video. We also did that using a masking tape to form a pattern.

Change the title : Inside a YEAH Factory in China

Ya, Ja, Ya, Yah, Ja. Humble sweet employee, with her *only* drawback being: Not being trained in illustrative arm gesticulations and presenter-speed broadcast English. Can we turn this around where she speaks Chinese and he has to comment in Chinese?&Plz... On another node: The workers seem dedicated, submissive, focused, efficient every minute of their work day. No wonder they will (and already have) surpass the glorious USA. For the presentation: That format is awkward, because you have chosen a single female to - not to guide you - but to be dragged by you - through the factory. Get a person who is on the same eye-level as you (literally) to accompany you who 100% dominates English, and it would feel much less humiliating. Cheers,

This is brought to you by .. Inception ... A tour within a tour...

shes just saying yes the hole time

yah yah yah yah yah yah yah yah yah yah yah yah yah yah yah yah yah..................

you're explaining all things to em.

I'm glad you're the host because without your energy, it would be like watching one of these machines doing the same damn thing your entire life. AKA, boring.

He could have just done this on his own

Yaaah yaah yaah ........ yah .... yah yahhhh yaaah

Wonder why Foxconn wasn't sponsoring a PCB video.. jk this company sucks about how they treat their workers. And again a great informative video thanks a lot sir!

next episode: "inside a nazi u-boat base"

lilly is a cutie pie

May you go to AliExpress ?

Normal people: Wow what an amazing video, I sure learned a lot! Me: haha at 9:00 she says peepee

Ya ya ya ya ya yaya¥¥¥

The narrator unfortunately have this very common problem of a speed issue i.e. although he talks to somebody and kind of ask a question he comes up with the answer . . himself . . very stessing

This video is better than Discovery channel..thx man

She spent more time with him than she would with her boyfriend.

Very funny, it looks like the Chinese lady have visited this guy somewhere in America and this guy is giving her a factory tour. Ya Ya Ya Ya Ya YA

I would not listen more than a minute to this guy. But the factory tour was impressive.

I'm stunned they still us lithography. I just assumed they would expose with laser. I guess its still faster?

hah, he is getting a wee pot belly :) .. happens to the best of us pal..

22:40 things that shouldn't connect do connect

Yaaa yaaa yaaa yaaa yaaa yaaa..

It seems like she don't want to share much about her factory with you but , you are forcefully doing it. and seems you have exposed most of the secretes of the factory,which she didn't wanted. Best of all good tour of the factory's manufacturing process

that engineer showed up only start and end of the video. Most probably he isn't an engineer. :O

Thank

Would love to see an assembly line.. maybe SeeedStudio?

this is amazing those days machines still using windows xp video on 25:25 second machine start up :D holy gral of windows :D

Lol, looks like Walter White on the thumbnail

He gave her a good tour of her manufacturing plant.

Turn up your mic and yell less.

Brilliant - just ordered some PCBs from JLC and it's amazing to see the process actually working. On the website you can even track which part of the process your PCB is going through in real time. Great video!

Copper plating is the process to get copper in the holes. There are a few different ways to do this. One is called the black-ink process. When the board is drilled , deburred and cleaned the barrel left behind by the drill bit ( the actual hole ) is basically FR4 material. first we are going to 'roughen' that up using a chemical process. This etches the FR4 material and makes it porous. This is happening on a microscopic level. After washing this chemical off we will immerse the board in a new chemical. this chemical soaks into the FF4 where it has been made porous. The board is now moved to a tank colding 'black ink'. this is essentially carbon powder dissolved in a chemical. The chemical soaked in the board and the new chemical react with each other and the carbon powder is 'sucked' into the Fr4 material while the chemical comes out of the Fr4. Technically this is called an ion swap. So now you end up with the walls of the hole being impregnated with carbon. we don't just want to 'coat' as that would peel off to easily. we really want the carbon to stick in the walls as opposed to simply being on top of the walls. The carbon is conductive and that is the key to the next step. After drying , the board is wired up to a current source and submerged in a fluid that contains dissolved copper. somewhere else in the bath there is a 'donor' plate which is a pure copper plate. An electric current now dissolves this donor plate copper and deposits on the circuit board. Anything that is conductive on the circuit board will grow copper. So the existing copper grows up , but also the carbon grows up. They typically grow the same amount of copper as there is already on the board. A run of the mill board has 17 microns of copper to begin with so the final copper thickness is 35 microns wile the copper in the holes is also 17 to 18 microns. After this electroplating the board is washed and they do the whole process of applying photomask , exposing to a film and UV light , developing , etching again. There are slightly different processes. The black ink process is being phased out for so called electroless (no current needed) plating. This is a chemical bath that deposits nanoparticles of copper in the fr4. Then they do the electroplating process. Most big production companies have switched away from carbon over a decade ago. some small outfits still use it. In the video : the reason for the yellow light is that the photomask is only sensitive to specific frequencies of light, most notably the dark blue to UV spectrum. Yellow is about as far away as possible from blue in the color spectrum. So the yellow light does no affect the photomask. The reason the boards disappear in the machine and you don't see the exposure is that they use very strong ultraviolet light. You do not want to be exposed to that as a human... it is so strong you'd get sunburn within a few seconds and it will ruin your eyes in a few tens of seconds. ( it's the 'bad' kind of UV ,like welding light )

Its amazing now america and europe let all this technological manufacturing go to asia let alone a freaking communist country.

She shy

Excellent video. Who just love that classic green color!

Is he here for factory tour or to Flirt with her and do OA?

Thats amazing.

Very, very nice!

Raspberry Pi factory in China

麻烦增加中文字幕,谢谢作者!

Hehehhehe she said pipi

the scale of Chinese production always amazes me. How much would our everyday electrical items cost if all this work had to be done in the west and wasnt outsourced to asia powerhouses? Amazing. I am dort of grateful but at the same time realise that the west has had its manufacturing base severely reduced which is not good. What would this world look like if China hadnt undergone its change i wonder?

Painful to watch this guy being just about as stereotypical annoying American as he could be.

lol you can see how done she is with this guy. who the hell conducts themselves like this?

I think we offered them the HASL equipment

supper

Sorry second comment, I went to a factory in liuzhou, they made earth moving equipment, so way out of your field however, the had robots doing all the welding, the entire factory has about 10 people and the rest was robots, beyond amazing, I wonder if you could do a video about the robotic automation of these heavy industries, it blew my mind

very cool factory tour, your excitement comes thru, not sure the tour guide knew how to deal with the crazy white guy

Consider **subtitles** if it will allow the people in the company to talk more. You are probably missing out on nuances they would point out (often the most interesting bits of info) when you generalize for them

yeah ... yeah .... yeah

Why so many Chinese companies dont hire a proper PR person or some sort of manager who speaks English and maybe some other language fluently and is open to speak and not like this guys...yeah yeah ok yes aham Btw great video ☺️ my next PCB order goes to them

This is like the teacher-apprentice going on the final factory round, any ways, that is a good demo too! xixi!!

amazing video. Subscribed!!!

Hey, I've been to that factory on a tour back in 2014. They sure have expanded a lot since then. Now they operate at Shenzhe, Huizhou, and Zhuhai, etc. I actually thought you were gonna move onto the SMT process. They also make those stencils and assemble PCBAs too. There's a web store integrated in their web system and you may order components or just have your PCBAs assembled with components available at their web store. Anyway, you may have made such videos before. Just a thought.

STOLEN WESTERN TECHNOLOGY.

Why am i watching this for the 3rd time. LOL. Love seeing the process and the enthusiasm. Yeh, my friends call me weird getting excited with raw electronics.

yeahhh , yeahhh , yeaahhhh , ho yeah ,,,,,,hooooo yeah

12:26 yeah dude, 3 kind of holes

Absolutely incredible

Classic.............

i wanna see TSMC and Global Foundries - Silicon chip Producttion's from x86-CPUs and GPUs; from AMD and NVIDIA..

i wanna see pc motherboards built this way from the same steps??

amazing! thank you!

wow I would like to refer customers to jlcpcb

Cool beans....advise more decaf I agree with others you should've let her talk more,but you do a great job!!!

nice one,

Maybe you could do, without so much waving with your hands,its irritating a little....

I think I would have enjoyed it more if we got rid of the overly loud and hyper guy and go someone who could modulate and calm down a little. Why the two Chinese were there is anyone's guess. The head technician was seen twice and said almost nothing and all we heard from the poor girl was Yea. Please use someone better next time and I may just subscribe. I recall having Japanese gentleman fly to Australia simply to show a CB radio club a movie (no video) of how a CB was made. He ran that video at least 10 times and I watched it each time. Absolutely fascinating.

Best quality man! :-D

it's not blue light that hardens the stuff, it's free radicals from ultraviolet light

It seems all of the machines are bought from somewhere else, say, USA.

Now I see why They say that Americans are so loud. I think you should exercise to make your voice deeper. But Nice video Thank you Bro

you move your hands too much

they're called traces and solder pads in a pcb, not wires. and it's not really that simple especially with multi-layer pcb

amazing

We all know who's getting some....

This guy has the most annoying voice I've ever heard. Had to click off.

I wonder if lily got her wet willy filled with Scotty’s silly willy?

I used to work for one in the U.S. 2001, it moves to China...overnight over 300 jobs lost!! I see it now... Johson matthey is one of those company...

not really. i wouldn't say it's stolen. and even if it was, it's just a matter of time until they would've discovered it anyway. just like the french tried to keep smokeless gun powder a secret, but it didn't matter

mmhmm yea

China sex toy factory next ?

Strange Parts, dont listen to the dingle balls who dont understand. How could viewers not see Lily struggling from the start. It would have been a very uncomfortable interview without your help.

Is she programmed to just say "ya, ya, ya"?

Who is the visitor actually? The male or the female? And whose factory is being visited? Again the male or the female? If the answer is the male then he don't need to come he's already knowledgeable.

Why tell you so much? She give the tour. She must must tell you.

1:17 - Combined, they contain the sum total of knowledge in the universe.

Yeah ☺☻☺

These guys are making my boards right now! So cheap it's incredible. Little boards (less than ~3" per side) are $2 for 10.... You can't make this up!

I hope after this tour she learned something.

I've always been wondering how actually they are made.. Thank you for this amazing video :)

Scotty talk to much

americans always say pwb printed wiring board. but we call it pcb printed circuit board.

Amazing China.

I love this video, I used to work for SCI in PCB assembly and ICT testing. I always wondered how they made the multi layered PC boards. We had Fugi machines that could place the parts on a Apple server board back in 1992 in under 2 minutes top side and 30 seconds on the bottom with glue before the top melt and solder wave. It's no fun when a mistake is made on a part reel, imagine hundreds of boards with 0 ohm resisters where 100 ohm resisters are called for. The HP ICT test machine see's a short and pops that board off the vacuum tester fixture FAILED for crossbar shorts. It's pretty sad that all this manufacturing has moved to Indochina, really good jobs that ran away from US shores like the HD voice coil and IC chip fab technology. If you ever get the chance to go into a silicon wafer fab, you will be amassed at the technology. I had the chance at Cypress semiconductor (CMOS chips), the total monkey suit is required so video would be very difficult.

You stress me !! Blablabla speed speed speed ...but good video

I am chinese,this video very nice。

1:15 2:12 and Soo she only siad yaa yaa !!! I thought the man was explaining her rather she was just listening and like yaa

It looks like he is taking her on a tour in her own factory :).

you are in a clean room without a clean suit on .. :-)

"Why is it so yellow"

enjoyed, Thanks

When goods are not delivered by JLCPCB they claim customer has to proof goods were not shipped and its customs or others fault!! Ordered 2*10 PCB's with 1 stencil, received only the stencil, no resolution on the PCB's. JLCPCB have no process controls (e.g. 8D), just claim they are not at fault until proven otherwise

Shenzhen RC Hobbies Mfg Videos !

while (!video_end) { women->says("Yeah"); }

Make the post subscription comment without the people that guide you through the factory. You created an unnecessary weird moment.

anyone else notice the windows xp @25:17

This tour lady, Lily has massive English proficiency problem, or other word a common problem in China. The Chinese must start to learn beyond their border. To make great advancement open minds are needed. Too conservative will spell out self defeated.

This is easy stuff. The Chinese people must start to invest into producing “CPU” ( Central Processing Unit ). It is (cpu) the brain of the computer which is on the world there are only 2 company in the US able to manufacture it, they are INTEL and AMD. It is extremely sophisticated, a chip within a chip, a circuit within a circuit, all are miniature. If China can manufacture this CPU, the market share would be trillion of dollars. Can the spirit of the Great Wall and the Long March achieve this?

wow amazing to see such a complex factory going so smooth for multiple projects at the same time. intresting video thanks for sharing :)

Is it illegal to bury 1970s capacitors in earth ?

Lol 25:20 loading windows XP

looks more like he is explaining to her!!

Dude, who is giving who a tour? Let the girl talk.

nice girl :)

It takes me a laser printer and an iron to make a PCB LOL :)

How nice is chinese is and how fast western is.

Lily's so cute!

Just 1 more ya i swear I'm gonna kill you ...

I think its odd how so many professionals in China take on "western" aliases rather then their actual names. I would actually prefer to talk to a real person and call them by their actual name. Most of the time I don't have to worry about pronunciation since communications are usually digital.

Oh yeah.

Makerfabs have similar manufacturing service.

This is why china rules the electronic market. Thanks uploader amazing video.

Quite possibly the most interesting video I have seen on youtube. Many thumbs up!

Girl, is yo name UV? Cuz you makin' me hard.

whatta cretin

It's all rubbish man. So much efforts

Can a US factory produce them as fast and cheap as China’s? No

这个女孩很可爱!

1:10 That... that was close. He saved it.

If it weren't for the fact that he explains this stuff more efficiently than the lady, I'd argue that she basically got manxplained on the trade she is probably an expert of. Yeah!

As Mems engineer the fact that you don't have gloves to touch stuffs kills me inside

Dude û gave her a tour of her factory

Thanks for a great video.

Lilly ....i love you .

By the way who was the tour guide..?

Thank you for spreading knowladge and curiosity :)

After seeing this man... I realised.. China is a heaven for people like this YouTuber

Wow! This was a super-informative video. I teach A+ computer maintenance so I can't wait to share it with my students.

If I were a teen now, I think I would study Chinese. This country has come a long way from making a lot of junk to making some very nice items. Especially, electronics. Move over Japan. Some of the test equipment coming from China is approaching HP and Tektronix quality but at a price that is a game changer. Rigol and Siglent are two that come to mind.

I am surprised how labour intensive it is. I know the labor is cheap. But still too many given the size of the company which can add more automation. My guess is this factory don’t make really high end pcb, like 16 layers+. It is just too many human involvement for fine machinery

They did up to 4 layer at this factory. There are pcb houses in Shenzhen that will do 16+ layer though

it looked more like he was telling her how everything worked, instead of vice versa. Everytime he would say something, she would just say, "ya"......lol

Typical for China that they dont care about quality thats why people still order in germany. We need a couple of days more to produce but then the product is perfect.
