Technology is an assembly technology of electronic components, which is suitable for surface mounting of circuit boards (PCB). Compared with the traditional plug-in technology, SMT technology directly installs electronic components on the surface of the circuit board without connecting them through sockets or holes.
The main components of SMT technology include electronic components, PCB and welding methods. In SMT process, electronic components are coated with solder paste.
Paste) is accurately installed at the target position on the PCB, and then heated by hot air or reflow oven to melt the solder paste and fix the electronic components on the PCB. Through this technology, miniaturization, portability and high-density electronic product manufacturing can be realized.
Compared with traditional plug-in technology, SMT technology has the following advantages:
1. Improve production efficiency: SMT technology adopts automatic equipment for assembly, which has fast production speed and is suitable for mass production.
2. Improve product quality: SMT technology avoids the problem of loose connection or poor contact of sockets and reduces the failure rate.
3. Improve the reliability of the circuit board: SMT welding makes the connection point stronger and can withstand greater mechanical stress and vibration.
4. Improve the performance of electronic equipment: SMT technology makes the pin spacing of electronic components closer, which can make smaller and lighter products and provide higher integration.
Generally speaking, SMT technology is an advanced electronic component assembly technology, which is widely used in the manufacturing process of various electronic components.
