China Electronic PCBA Assembly Service
♦ What is Electronic PCBA?
Electronic PCBA (Printed Circuit Board Assembly) is the process of mounting and soldering electronic components onto a fabricated PCB (Printed Circuit Board) to create a functional circuit. Unlike PCB fabrication (which produces the bare board), PCBA involves populating the board with components like resistors, capacitors, ICs, and connectors.
♦ Key Stages of PCBA
♦ Types of PCBA Services
Type | Description | Best For |
---|---|---|
Turnkey PCBA | Full service—supplier handles PCB fabrication, component sourcing, assembly, and testing. | Startups, companies wanting hassle-free production. |
Consigned PCBA | Customer provides components; assembler only does placement/soldering. | Cost-sensitive projects with existing parts inventory. |
Partial Turnkey | Hybrid approach—some parts supplied by customer, others by the assembler. | Customized builds with specialty components. |
