Many people who are just beginning to contact the electronics industry are often confused by PCBA, SMT, and PCB. It is difficult to distinguish the difference and connection between them. Next, I will talk about it in plain language. Talk about the differences and connections between PCBA, SMT, and PCB, and help everyone better enter this industry.
1. What are PCBA, SMT, and PCB?
1.1 The Chinese name of PCB has several names such as circuit board, printed circuit board, etc. PCB is used to support electronic components and provide circuits, so that a complete circuit can be formed between electronic components.
1.2 SMT is a popular process technology. Electronic components are mounted on the PCB empty board through a process, also known as surface mount technology.
1.3 PCBA refers to the processing process of one-stop services such as SMT patch, DIP plug-in, testing and finished product assembly after purchasing raw materials.
2. The difference between PCBA, SMT, PCB
2.1 PCB, also known as circuit board, is a necessary raw material for SMT processing, and it is only a semi-finished product.
2.2 SMT is a circuit board assembly technology. It is the most popular process technology at present by buying back the PCB substrate and placing the components on the PCB through technology. This is the most popular process technology at present.
2.3 PCBA is a perfect processing service on the basis of SMT, which increases the procurement of components, and the subsequent testing and assembly of finished products. It is a service model that provides customers with one-stop service and is the future development direction.
After the processing of an electronic product is completed, their order should be PCB→SMT→PCBA. The production of PCB is very complicated, while SMT is relatively simple. PCBA is about one-stop service.
