Cheap PCB Assembly from China [Test & Tutorial]

[@linagee]

Use reverse LEDs that shine downward and put holes in the PCB. Then you can have a one side SMD load. :-D

[@jordanwaeles]

I checked but I didn't find any reverse-mount LED in their library of placeable parts. Let me know the LCSC reference if you find some in their JLCSMT parts library...

[@stephen_hawes]

I'm so excited that this is becoming such an inexpensive service. Thanks for showing us the process!

[@UnexpectedMaker]

I stayed until the end just for the music! Took me to my happy place!

Is there any longer version somewhere? :) I guess it's composed by bitluni so only he can release it.

Sounds a bit like Celeste music

[@marvinblue6825]

Custom Esp32 boards, here we come 😁 I hope they make connectors available.

[@bergamt]

I wish they allowed ESP32 modules rather than just the chip

[@p_mouse8676]

I personally do an hybrid between the two. So all less (simple) important components are already being assembled. Only a few high quality/special or big/heavy components I do myself. Depending on the size of the batch obviously. That way you don't have a better control over quality, but shipping is also a lot less (because of the weight)

[@maxhouseman3129]

Good idea! I will test this method for myself. In particular because I have a lot of very expensive and seldom chips that I want to use. Better I solder them on my own.

[@simsung321]

Try PCBway. Prices are similar usually for the most part and they do assembly on both sides and any color pcb!

[@Paul_VK3HN]

Just starting to do this, thanks for sharing your customer experience report.

[@MakerFabio]

Thanks for sharing

[@JeremyCook]

Thanks for the video. Very cool, hope to try this kind of service soon!

[@syspcb]

SysPCB is also a good choice for those who has higher requirement in assembly

[@Really2950]

Bitluni always has super great videos. But this one has his best news ever. I’ve been waiting so long for surface mount options

[@joey3291]

I've used their service in and out of china, the slow international price is almost as cheap as the domestic shipping, although it's much slower, but considering the price it's still unbeatable...

[@topfastpcbs1512]

sure,Every extra penny deserves its value

[@andymouse]

The future looks good !

[@donaldklopper]

Exciting times ahead!

[@TheEmbeddedHobbyist]

I don't know why but i find soldering very relaxing and can sit for hours a day soldering SMD's. properly less stress after doing the design is good for you. Or was it the room was quite a way from the boss's and you could have the radio on loud. i did manage to keep the room telephone free for 2 years :)

[@envt]

Great video. I hope they add connectors soon!

[@HandFromCoffin]

This stuff is simply mind blowing.. How can they do this for these kind of prices? Amazing.

[@gkelly]

Loved the video! Which UPDI programmer do you use?

[@ein57ein]

AWESOME! This could make getting some QuinLED-Dig-Uno boards MUCH easier

[@smtfabpcba9630]

great work!

[@fluiditynz]

The name "Charlieplexing" annoys me because I published before him on piclist and I wasn't even the first! I went a bit retro last week and should have 10 small round black PCBs on courier setting out from JLCPCB today, a CH32V0003 8 pin chip driving 20 leds in a heart shape with battery clip on back, test touch sense points going back to 4 pins and ISP clip points. My first one was a circle with 12 LEDs on 5 pins of a PIC12C508 and the reset pin configured to cycle between off and 3 display series. It will be interesting to see if I can do touch sense between LED driving without annoying flicker.

[@fluiditynz]

I'm curious as to your component on the other side from the reset switch BITLUNI? I got my boards last week and assembled a few of them, killed a few CH32V003 getting my code to not kill the SWDIO pin and now have some software doing patterns on my 20 LEDs off 5 pins, looks pretty eye catching, the battery clips arrived yesterday and that was even better to have them mobile from my ISP clip. I'm going to try touch as input to control the chip but need to look up the data sheet again, I need to find lowest standby current and pop the micro into sleep every time it's not busy which is most of the time.

[@DangerousPictures]

I tried it out a couple of weeks ago and now they support kicad and Connectors

[@avejst]

Great video and walk-through Thanks for sharing :-)

[@linagee]

Where is the checkbox to automatically lay out your board for you, automatically make a case for you, automatically do FCC testing, automatically make a product box, automatically list it on Amazon and ship it to their factory, and automatically count all the $$$ coming in, lol. (Soon I hope, although I'd guess that would put many people out of a job!)

[@Davedarko]

let them first do other colored PCBs and dualsided production, please :D

[@arduinomaker7210]

wow, nice work

[@ZaPpaul]

So the first thing you do is export the bom. How did you get the bom in the first place and set that up? I load the kicad pcb in and have no idea how to place the components from the library to the pcb.

[@BurkenProductions]

What's that cool 8-bit tune at the end of the video called??

[@gameofpj3286]

Damn, thats an amazing feature :O

[@alexloktionoff6833]

Using AVR, why not to switch to CH32V003 RICV?

[@HamzaHajeir]

Nice explaining video! How about KiCAD sketches ? Would there be problems in ordering from lcsc too ?

[@santopino2546]

I discovered you through a Keysight video. I was tempted to use the PCB assembly a few months ago, unfortunately nearly all my components where: not available, no substitute or not on the basic list. So for my needs it's totally useless.

[@lorenzoporciani]

I was thinking, what if you could replace the button by exposing some copper on the front side (maybe the dot?) so that when you touch it you ground it and it acts as a switch?

[@powil4ss]

what kind of ultrasonic cleanser are you using? and in what media? thanks!

[@Stabby666]

This is interesting! I have ben using PCBWay for small run SMA (50 units at a time) and they take much longer per run - around 4 weeks. They do hand-hold quite a bit though, sourcing parts they don't stock when I supply part numbers, and also fixing some issues in centroid files (pick and place files). I'll definitely be trying some smaller boards with JLC though, to see how the process goes. I use Eagle though, not EasyEDA, so just need to compare the centroid files I guess!

[@SeanChYT]

Which chemical or cleaning liquid do you use in your ultrasonic cleaner? I have not been able to find Branson EC in Europe.

[@umarsajan5454]

If i want make new baord pcb where should i contact

[@sharedinventions]

I don't get how to combine panelization with SMT assembly in my order.

[@catafest]

this is a little confuse to me because you come with many changes... can you provide a correct video tutorial about how can use this online tools from design to the last step product made by jlcpcb factory. thank you!

[@robb233]

What was that bath thing for, you used at the end of your assembly? Thanks.

[@MrVolt]

Rob B It's an ultrasonic cleaner with isopropyl alcohol

[@manibharathy1994]

The 8 bit sounds at the end

[@alissonneres5067]

Why do you cook the pcb at the end? It is for cleaning right? I want to know more about the process or what is that machine

[@Davedarko]

that's an ultra-sonic cleaner filled with alcohol, to get rid of the soldering residues :)

[@belaterjek2635]

How can you get such a low price for shipping? I live in Hungary, and DHL starts from $23 and up for our JLCPCB orders, depending on the weight. As most of the boards we order are just plain pcbs, this adds a considerable amount to the total cost. If you order a best $2 offer, the final price-tag is about $25, which is ridiculous

[@jvqn6581]

It's basically subsidized. I think this dates back to a time when China as a developing country got foreign aid from (Western) European countries, both directly and indirectly as in this case (many European postal services were state-owned back then). There are now huge rows internally because the European postal services that do the final mile get significantly less for something posted from China than they would for a similar item posted domestically. I guess at some point the relevant contracts will be re-negotiated and shipping costs from China will rise to normal levels.

[@witawat]

6:58 what use clean pcb , this normal water ? thankyou

[@83hjf]

usually isporpoyl alcohol

[@Epsicronics]

You technically can use water but as someone stated they use isopropyl alcohol

[@TBL_stevennelson]

我一看到标题就认为是JLC,结果果然是 JLC喵（X When I see the title of this video, I thought that may be JLCPCB did this...and, yep.

[@NonExistChannel]

Can someone tell me what kind of solution he is using with his ultrasonic cleaner?

[@vivekanandottalingam]

Probably isopropyl alcohol with a little swig of acetone. Acetone optional.

[@MetalheadAndNerd]

Unfortunately the portfolio of components is extremely limited. If you only need LEDs and resistors it works but as soon as you need not any diode but a specific diode the service isn't for you anymore.

[@josefaschwanden1502]

Also they dont do BGAs
