[0002] PCB is an important electronic component, a support for electronic components, and a provider of circuit connections for electronic components. Because it is made using electronic printing technology, it is called a "printed" circuit board. Before the advent of printed circuit boards, the interconnection between electronic components was directly connected by wires to form a complete circuit. PCBA means that the PCB blank board goes through the entire process of SMT mounting and then DIP plug-in. In short, the PCBA board is a PCB board that has been soldered and assembled with electronic components.
