What is PCB, SMT, PCBA?

Many friends who just contact the electronics industry, will not understand what PCB, SMT, PCBA, do not know what is the difference between them, what is the correlation. Shenzhen kingford is a professional PCBA manufacturer with its own PCB board factory and SMT processing plant. Next, we will introduce the differences and connections between PCB, SMT and PCBA.

1, PCB Chinese name circuit board, circuit board, printed circuit board and other names, PCB is used to support electronic components, and provide lines, so that electronic components can form a complete circuit.

2. SMT, also known as surface mounting technology, is a popular technology in which electronic components are pasted on PCB empty board through successive processes.

3. PCBA refers to the one-stop processing process of SMT patch, DIP plug-in, test and finished product assembly after purchasing raw materials.

The difference between PCB, SMT and PCBA

1, PCB, also known as circuit board, is the necessary raw materials for SMT processing, only a semi-finished product.

2. SMT is a kind of circuit board assembly technology. It is the most popular technology at present to buy PCB substrate and mount components on PCB through technology.

3. PCBA is a kind of perfect processing service based on SMT, which adds procurement of components, and later testing and assembly of finished products. It is a service mode to provide one-stop service for customers and the direction of future development.

When the processing of an electronic product is completed, their sequence should be PCB→SMT→PCBA. The production of PCB is very complicated, while SMT is relatively simple. PCBA pays attention to one-stop service.
