PCB, PCBA and PCB assembly are closely related, but they describe different stages of electronics manufacturing. Using the correct term helps suppliers understand whether you need a bare board, assembly only, or a coordinated sourcing-and-assembly scope.
What is a PCB?
A printed circuit board is the bare board that mechanically supports components and electrically connects them through copper traces. Layer count, material, thickness, copper weight and surface finish belong to the PCB manufacturing specification.
What is a PCBA?
A printed circuit board assembly is a PCB after electronic components have been mounted and soldered. Depending on the project, inspection and testing may also form part of the assembly scope.
What is PCB assembly?
PCB assembly is the manufacturing process that converts a bare PCB into a populated PCBA using SMT, THT or mixed assembly methods.
Define the scope clearly
If you need only bare boards, request PCB supply. If you already own the boards and components, request assembly. If you want the board, component sourcing and assembly coordinated together, state that explicitly and clarify whether testing or programming is also required.

Frequently Asked Questions
Are PCB and PCBA the same?+
No. A PCB is the bare printed circuit board, while a PCBA is a PCB populated with electronic components.
Is PCB assembly part of PCBA manufacturing?+
Yes. PCB assembly is the core process of placing and soldering components onto the bare board.
Can the customer supply the PCB?+
Yes, depending on the project model. The responsibility for PCB supply should be defined during quotation.
