content: Hello guys.I have to say I'mverynew to PCB Assembly topic. I'm currently quoting some Projects with Assembly service on several sites. All of the component's part numbers were sourced from Digikey, so I upload a BOM with their Part Numbers and all OK.But... I have the following question:- If I want the PCBs to come with adisplay, for example, this OLED 1.3" from Aliexpress:Quote- Do you think they can provide me the screen with the PCBs ?- Could be difficult to them to source a product fromAliexpress, Alibaba, Banggood, etc? I mean, they are in China...I would be eternally grateful if you could tell me your experiences.Best regards,Max

content: I seriously doubt anyone will source anything from Aliexpress, it is just too much risk. You would have to do that yourself and send the assembler a box of parts.Also, why not ask assemblers?

Try lcsc.com, they will source lots of stuff, if its not in their price book. They are part of the same bunch as JLCPCB. You are on a steep learning curve though.

Who is going to deal with the seller? The assembler? Of course, not.Also, I suspect this whole thing is just spam, which would further my point.

content: Quote from: alkonosst on May 01, 2019, 04:41:13 amYes many small electronics companies based in SZ which offer their services Internationally would be able to source the display for you as well (at least if you are ordering more than a few pieces assembled). The challenge is that there are many variants of these kinds of display module so you would need to specify a particular manufacturer and part number of the display (which may be a little tricky for you if you are used to ordering from Banggood etc). Anyway just talk to a few and see how they can help you.You may find it more productive to get quotes through companies advertising assembly services on aliexpress etc rather than going through an online ordering panel, because you are asking for more than just standard PCBA. Ideally you would try more than one company with a test order until you feel confident enough with one to trust for larger orders.

content: Quote from: ataradov on May 01, 2019, 05:18:47 amThat's the whole idea of my post, to ask you if anyone has been done the same, I mean, quote a PCB Assembly + some external part (dev. boards, displays, motors, etc) in trusted sites likePCBCart, PCBway, AllPcb, SeeedStudio, 7pcb, etc etc...A colleague of mine, has quoted in the sites mentioned above, and no problem at all, but his project didn't include a Display or extra thing. Mine does.Quote from: janekm on May 01, 2019, 08:46:15 amMmm... yes. I was thinking that. But... because I'm new, I don't know if I can trust in Aliexpress PCB Manufacturers to buy thousand of units from them.That's the thing. I'm hoping that someone can tell me their experiencies like mine.Maybe recommend me a Manufacturer that has done this method?Thanks

content: I have bought things from aliexpress, checked them out, then located the company, made contact, sometimes visited them, and then dealt with them directly. Often they will also have a presence on alibaba where you can buy directly.On aliexpress, i make the assumption that I shoud'tn buy something that i cnat' afford to go wrong. Its a very quick way to assess if somethign is good or not.

content: Agreed! I don't think any company would be willing to deal with a third party seller on Ali.
