About this Gig

I provide PCB/PCBA production management services in China, from design review to manufacturing, testing, bring-up, and firmware support.

I have extensive experience with PCB manufacturing processes in Shenzhen and work closely with major PCB/SMT suppliers such as JLCPCB and HuaQiu PCB. As an Open Source Resource Review Member, I can also benefit from special production discounts.

For prototype, medium-volume, and mass production, I can help optimize the manufacturing process, reduce PCBA unit cost, manage schedules, and handle technical communication with factories.

My service can include PCB review, BOM review, production coordination, component sourcing support, power-on testing, board bring-up, debugging, and bring-up firmware development.

For suitable production orders, the total PCB/PCBA cost may be lower than ordering directly through standard online channels.

My goal is to save you time, reduce manufacturing risks, control production cost, and provide one technical contact for the complete PCB production process in China.

    He is very smart technically, but not so good with dealing with customers or addressing any concerns that you might have. You would have to really push him a lot to get what you are asking for.
