A . About PCB
PCB is the abbreviation of printed circuit board. It is an important electronic component in the electronics industry, a support for electronic components, and a carrier for electrical connections of electronic components. The PCB of the circuit board factory is widely used in the production and manufacture of electronic products, and its characteristics are as follows:
1. High wiring density, small size and light weight, which is conducive to the miniaturization of electronic equipment.
2. Reduce wiring and assembly errors, and save equipment maintenance, debugging and inspection time.
3. Facilitate mechanized and automated production, increase productivity and reduce the cost of electronic equipment.
4. The design can be standardized to facilitate interchange.
B . About PCBA
PCBA is through the whole process of SMT on PCB empty board, and then through DIP plug-in.
SMT mounting, mainly using the mounting machine to mount some tiny parts on the PCB.
DIP is “plug-in”, which is to insert parts on the PCB board. This is the integration of parts in the form of plug-ins when some parts are large in size and not suitable for placement technology.
Note: Both SMT and DIP are ways to integrate parts on the PCB board. 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 drilled holes.
Summary: PCBA generally refers to a processing process, and can also be understood as a finished circuit board, that is, PCBA can only be counted after the processes on the PCB are completed. The PCB of the circuit board factory refers to an empty printed circuit board with no parts on it. In general, PCBA is a finished board; PCB is a bare board.
