PCB & EMS Manufacturing Services

What We Offer

PCB & EMS Manufacturing Services

Full-spectrum EMS solutions — from bare board fabrication to turnkey assembly and testing.

BELI Technologies runs five services under one roof in Shenzhen: PCB fabrication from 1 to 42 layers, SMT and through-hole assembly at around 52 million placements per month, component sourcing through authorized distributors, wire harness assembly, and functional testing. There is no MOQ for prototypes — quick-turn prototype assembly takes 48 hours once boards and parts are ready, while turnkey orders including sourcing typically run 2 to 3 weeks.
