Turnkey PCB Assembly with Component Sourcing Included, 100% Electrical Testing, and Multi-Stage Inspection

Turnkey PCB Assembly Manufacturer for Complete OEM Projects

Huayihai provides turnkey PCB assembly services for OEM customers, covering the complete process from Gerber files and BOM through component sourcing, PCB fabrication, assembly, testing, and delivery.

With turnkey service, a single manufacturing partner manages the entire build: components are sourced according to the approved BOM, boards are fabricated and assembled under the same quality process, and every assembly is verified before shipment. This reduces coordination between multiple suppliers and keeps responsibility for the final result in one place.

Custom Manufacturing Only

We provide turnkey PCB assembly according to customer Gerber files, BOM, and technical specifications. We do not supply ready-made replacement assemblies or standard products.
