Assembly and integration

PCBA and EMS services in China

Board types describe what is fabricated. These pages describe what is assembled and integrated around it. We keep the two dimensions apart so a factory is never credited with a service just because it builds the bare board.

SMT Assembly

Surface-mount technology places components onto solder paste printed on the board surface, then reflows them in a controlled oven.

Read the service definition

A service page is released from noindex only after at least eight factories have a verified, service-specific record. Until then the page describes the service and stays out of the index. This is deliberate: a list of names without ownership and subcontracting data is not a sourcing signal.
