PCBA is the abbreviation of Printed Circuit Board Assembly, that is, PCBA is Through the parts on the PCB blank board SMT, and then through the entire manufacturing process of the DIP plug-in.

PCB is the abbreviation of Printed Circuit Board, because it is manufactured by electronic printing technology, it is called "printed" circuit board. PCB is an important electronic component in the electronics industry and a support for electronic components. PCB has been widely used in the production and manufacture of electronic products, and its uses are very wide.

The difference between PCB and PCBA

1. The difference in function

The role of PCB is to make a program (including data) that cannot run independently in a multi-program environment into a basic unit that can run independently, a process that can be executed simultaneously with other processes; it is a process scheduler that can be executed on the CPU The program segment in the process.

In PCBA board, excellent circuit design can save production cost and obtain good circuit performance and heat dissipation.

2. Essential difference

The only sign of the existence of a process is the PCB, and the process control block is a static description of the process. The circuit board is the support body of the electronic component and provides the circuit connection of the electronic component.

The printed circuit board essentially belongs to the manufacturing process, and the blank PCB board completes the entire manufacturing process through the upper part of the SMT or the DIP plug-in.

As can be seen from the above introduction, PCBA generally refers to a processing process, and can also be understood as a finished circuit board, that is, all processes of the PCB board can be carried out after the PCBA is completed. And PCB refers to an empty printed circuit board without any components.
