PCBA processing is the process of assembling printed circuit boards, components, etc. In this process, it is necessary to fix the components on the circuit board to the printed circuit board by soldering, forming a complete electronic circuit system. PCBA processing usually includes processes such as component procurement, SMT assembly, DIP plug-in, testing, and packaging.
SMT processing is the process of attaching ultra small, ultra-fine, and ultra light electronic components such as surface mount capacitors, surface mount resistors, etc. onto PCBs through a high-precision device.
The difference between PCBA processing and SMT processing
1. Different production processes
PCBA processing and SMT processing use different production processes. SMT processing usually uses unmanned equipment for production, with a high degree of automation and high production efficiency, while PCBA processing involves many manual operations and the production process is relatively complex. Therefore, SMT processing requires a production base built with high-end and precision machines and advanced technical support, while PCBA processing requires relatively simple integrated equipment.
2. Different types of components
In the PCBA processing, a wide range of components need to be processed, such as resistors and capacitors, semiconductor devices, power supplies, etc., while SMT processing only involves surface mount components.
3. Different production costs
Due to different production technologies, the production costs of PCBA processing and SMT processing are also different. Usually, the production capacity of SMT processing is higher than that of PCBA processing, so their production costs are relatively lower.
