What is the differrence between PCB and PCBA?

A Printed Circuit Board, or PCB, is an autonomous module of interconnected electronic components found in devices feeding from common pagers, and radios to sophisticated radar and computer systems. The circuits are formed by a thin layer of conducting material deposited, or "printed," on the surface of an insulating board known as the substrate. Individual electronic components are placed on the surface of the substrate and soldered to the interconnecting circuits. Contact fingers along one or more edges of the substrate act as connectors to other PCBs or to external electrical devices such as on-off switches. A Printed Circuit Board may have circuits that perform a single function, such as a signal amplifier, or multiple functions.

 

 

Also, A PCB (Printed Circuit Board) is a board used to electrically connect and mechanically support components using pads, conductive tracks and several other features etched from sheets of copper laminated onto non-conductive substrates. There are various types of PCBs like single sided, double sided or multilayer PCB.

 

And on the other hand PCBA or, Printed Circuit Board Assembly is the board obtained after all printing solder paste on the PCB and then mounting various components like resistors, Integrated Circuits, capacitors and any other components like transformers depending on the application and desired characteristics of the board. A Printed Circuit Board Assembly usually undergoes reflow furnace heating to establish a mechanical connection between the PCB and the components.
