What Does PCB Assembly ?

Printed circuit board assembly, also known as PCBA, is the process of mounting various electronic components to a PCB. A circuit board prior to assembly of electronic components is known as PCB. Once electronic components are soldered, the board is called Printed Circuit Board Assembly (PCBA). The traces or conductive pathways engraved in the laminated copper sheets of PCB are used within a non-conductive substrate in order to form the assembly. Attaching the electronic components with the printed circuit boards is the concluding action before using the fully operational electronic device.
The PCB Assembly process is below:
