The difference between PCBs and PCBA

The first is PCB board, which is usually called printed circuit board because it is made by electronic printing. PCB board is a very important part of the electronic industry, is the pillar of electronic components, is the hub of electrical connection of electronic components. PCB has been widely used in the production and manufacture of electronic products. The reason why PCB board is widely used is that PCB board has its own unique characteristics: high wiring density, small size, light weight, which is conducive to the miniaturization of electronic equipment; Because the graphics have the characteristics of repetition and consistency, the difficulty of wiring and assembly is reduced, and the time of equipment maintenance, debugging and inspection is saved; At the same time, PCB board is more conducive to quantitative production and use, which is also a major feature.

PCBA board is the finished product of PCB board. Generally speaking, PCBA goes through the whole manufacturing process of empty PCB board SMT and dip plug-in. That is to say, some parts are assembled on the PCB board, and then plug-ins are inserted into the PCB board to form the final PCBA board. The process is more complex, and there are more requirements. It pays attention to the precision of the product, the manufacturing time is longer, and the cost performance of quantitative production is not as high as that of PCB board. This is also the reason why PCBA is not widely used in electronic industry. PCBA is a processing flow, which can also be understood as the finished circuit board, that is, PCBA can only be counted after all the processes on the PCB board are completed. A PCB is an empty printed circuit board.
