JLC PCB Prototype Assembly - Incredibly Cheap

[tglev]

There is also demo available in this site https://jlcpcb.com/smt-assembly
someone can test if you modify

to

https://jlcpcb.com/quote#/?fromDemo=no

Maybe even order that way?

This does not work, sadly.
The next button in the demo does not work either.

It does feel like we're getting closer and closer to getting PCBA!

It is open for test customers.
They still have bugs to fix, but it is going on really cheap. As soon as my project is working through the little bugs I will keep you updated, as of yet I can tell you:

- Gerber Upload as you know
- then you may enable SMT below where Stencil is also
- there you can select whether top or bottom is to be placed
- then you have to upload BOM and CPL
- youll have to confirm each part, which is nicely made with direct access to the datasheets and basics via dropdown in a table
- then you get a render of your pcb with parts where you can check placement

As of now I have some probs with a bunch of resistors they are working on

Best regards
Julian

PS: As the Demo seems to be working now, there shall be no need for screenshots?

I'm uploading a video this weekend to show the order process

[juwi]

they fixed it, my resistors work now

ah yes, no more then 10 so called extended parts are allowed per order.

F**k

na na...

Well, my order is out. I paid less than 10 Dollars for 5 placed boards with some 70 parts each (excluding part/PCB cost of course)

Yes, it is limiting but if you see it as a helping hand preventing you from having to place hundreds of biird feedings like resistors and caps - I like it.
The costly parts I can solder myself after checking the rest. But I dont have to solder some 60 caps and chip resistors. Winner

The placement preview stopped working after I added all parts - how many parts has your board?

yours julian

[mskeete]

The placement preview is slow. A few times I thought it had stopped working. On my first attempt I saw nothing as I forgot to convert the placement data to mm

[ddavidebor]

Ok so a suggestion: add a parameter JCLSMT-rotation in your libraries, add it to the pick and place csv file, then use excel to rotate the chips automatically

Preview didn't work on mine when I had an error with the file. It got sorted in the audit though

Exactly my thought. Any helping hand to solder all the passives is a winner in my book. Shame its green PCBs only, but that's only due to the early stage. Hopefully if it proves popular more options will exist.

[bitseeker]

Agreed. That's a great time saver for $2/board. Looking forward to seeing the physical results.

Well, for now not enthusiastic about the component availability.
This is what i was able to populate.
 

Positioning issues are a huge time sucker.
For now i think i am sticking with PCBWAY for this kind of boards.

The risk of making errors not having a professional doing the positioning is a huge bummer for me. If I screw this two times, my customer is going to kick me where the sun doesn't shine.

Something odd ball going on with your 5 Pin SOT-23's     They all seem 180degrees out.

Yep the only thing straight are resistors and capacitors

Hello I am beta user too.

There's some issue, some of rotation value ( Pick and place ) is mismatch.

I fixed it manually open the csv file myself.

About this rotation issue, Mainland china sz-jlc explained it very well. but i think they didn't on international port.

BTW there's some issue price is strange.



price is different between lcsc and jlc-smt.

and even that's correct there's no price MOQ 100 or 1000.

hmm I hope they fix this issue.

On my order, I notice some are cheaper than LCSC and a few more expensive. Nothing dramatic like that opto-isolator though.

Hi

I feel like an idiot right now but the site is not giving me the option for SMT assembly. I've tried multiple GERBERS, loggin in and out, changing browsers and wiping my cookies. Has anyone else experienced this issue or is service in some closed beta?

I'm really keen to test this service as the reflow oven at my University is broken and I'm not keen on soldering 100+ passives by hand.

Get a simple toaster oven with a triac. Monitor the temperature and feast on succes!

If I was the one paying i'd have done that a long time ago

It's open only to a limited number of existing customers now
If you send an email to the customer service maybe they can enable it for you

For now i think i am sticking with PCBWAY for this kind of boards.

Well I am sticking with PCBWAY for now, i got this board manufactured in 3pcs, spent 307 USD, of which:
* 160 of components (i've got 4$ PGAs and 2.5$ rotary switches there...)
* 100 for the 4-layer pcb. This would have been cheaper on JLCPCB, although I do not trust the quality or competence of the technical staff yet
* 30 USD for assembly and purchasing of all components from a variety of suppliers (including LCSC, the same as JLCPCB)
* shipping

So yeah JLCPCB prices are crazy low but hard to compare with the more rounded assembly services and may not end up being the cheapest solution after all

[bitseeker]

Thanks for the comparison, Davide.

[pmnxis]

placed order and paid finally.
There's chinese thanks giving day soon and some legit vacation day. So I guess my order will be delay.
I hope they accept professional business production too even there's higher engineering fee.

I will review my thing is come to me.
