PCB or PCBA, What Is the difference?

12

I heard so many times that our customer said I need  pcb with 18W.  They knew what they want, but they did not know how to say as always misunderstood the PCB and PCBA.  Today I would like to explain the differences.

A PCB (Printed Circuit Board) is a board that electrically connects electronic components using conductive traces, pads, and other features etched from copper foil laminated onto a non-conductive substrate. PCB’s can be single sided(one copper layer),double sided (two copper layers), ormulti-layer (outer and inner layers). Conductors on different layers are connected with vias (plated-thru. holes). Multi-layer PCB’s allow for much higher component density and design complexity.

A PCBA (Printed Circuit Board Assembly) is the board after all the components and parts have been soldered and installed on the PCB and now can accomplish the electronic function it was designed for. A PCBA usually undergoes reflow furnace heating to establish a mechanical connection between the PCB and the components.
