What is the PCB?
PCB =printedcircuit board ; Connected carrier.Since it is made by electronic printing, it is called "printed circuit board.
What is PCBA?
PCBA = assembly of PCBS. Box assembly forms a finished product. That is to say, the empty PCB board goes through SMT and then through the whole process of DP plug-in, which is referred to as PCBA
What is the difference between PCB and PCBA?
PCB refers to the Circuit Board, while PCBA refers to the Assembly of Circuit Board plug-ins. SMT manufacturing process refers to the finished Board and SMT manufacturing process refers to the Printed Circuit Board. If you see a Printed Circuit Board component such as a chip affixed to a PCB, PCBA may be interpreted as the finished Circuit Board.
That is on the PCB bare Board through SMT parts, repass DP the whole process of plug-in, referred to as "PCBA called printed circuit, and provides the electrical connection between components on the insulating substrate conductive graphics, known as the printed circuit, thus the printed circuit or printed circuit product called PCB (printed line (PrintedCircuie Board) short for printed circuit Board, usually put on the unique material, according to the scheduled design, printed circuit, components or a combination of the two conductive graphics printed road plate, also known as the printed circuit Board or printed circuit Board.
