After entering the PCB industry, we often encounter very similar concepts of PCB and PCBA.
1. About PCB
The abbreviation of PCB printed circuit board is an important electronic component in the electronics industry, support for electronic components, and a carrier for electrical connection of electronic components. PCB is widely used in the manufacture of electronic products, and its characteristics are as follows:
1. The wiring density is high, the volume is small, and the weight is light, which is conducive to the miniaturization of electronic equipment.
2. Reduce wiring and assembly errors, save equipment maintenance, debugging, and inspection time.
3. It is conducive to mechanized and automated production, improves productivity, and reduces the cost of electronic equipment.
4. The design can be standardized to facilitate interchange.
2. About PCBA processing
PCBA is through the entire process of PCB blank board SMT loading and then DIP plug-in.
SMT placement mainly uses placement machines to mount some tiny parts on the PCB board.
DIP stands for "plug-in", that is, inserting parts on the PCB board. This is the integration of parts in the form of plug-ins when some parts are larger in size and are not suitable for placement technology.
Note: SMT and DIP are both ways to integrate parts on the PCB. The main difference is that SMT does not need to drill holes on the PCB. In DIP, the PIN pins of the parts need to be inserted into the holes that have been drilled.
Summary: PCBA generally refers to a processing process, which can also be understood as a finished circuit board, that is, PCBA can be counted after all the processes on the PCB board are completed. The PCB refers to an empty printed circuit board with no parts on it. Generally speaking, PCBA is a finished board; PCB is a bare board.
