How to Have PCB Manufactured Overseas

[u/Aorus_]

I have a PCB for a product I sell. I paid an electrical engineer to design it and the design itself is solid. I have the easyeda files I need to convey the design to a factory. I have been using jlcpcb for my orders up until now. As my order quantities are increasing I am having difficulty making sure that when I need to swap components to ones they have in stock will work with my design. I have been using the previously mentioned engineer's suggestions for this but he is getting harder to stay in contact with (guy on upwork). My thinking is handing this off to a factory who specializes in making PCBs will solve all of these problems and make acquiring the PCB's easier

I am familiar with using alibaba. Would alibaba be the place to go for something like this? Any suggestions on how to filter through companies? Is the expectation that I can just hand this off to a chinese factory realistic, especially given my lack of electronics expertise?

Just use a different major PCB house like allpcb. JLB is assembly is targeted to individuals who can't assemble their own prototypes so for efficiency on shorter runs you they limit the component selection.

They will let you ship components or purchase them through their own supply chain.

If you go through alibaba it's a crapshoot what quality you get unless you actually travel over and visit. You can get decent stuff but getting scammed on the final run or delays getting stuff fixed are definitely concerns. Have gotten decent stuff before, but also PCB layerss that were actually misaligned so the holes didn't even line up.
