SMT technology, namely Surface Mount Technology (Surface Mount
Technology), is an assembly technology for electronic components and is suitable for surface mounting of circuit boards (PCBs). Compared with traditional plug-in technology, SMT technology installs electronic components directly on the surface of the circuit board without the need for connections through sockets or holes.
The main components of SMT technology include electronic components, PCB boards and welding methods. In the SMT process, electronic components are accurately installed on the target position on the PCB board by applying solder paste (solder
paste), and then heated by hot air or a reflow oven to make the solder The paste melts and secures the electronic components to the PCB board. Through this technology, miniaturization, lightweight and high-density electronic product manufacturing can be achieved.
Compared with traditional plug-in technology, SMT technology has the following advantages:
1. Improve production efficiency: SMT technology uses automated equipment for assembly, has fast production speed, and is suitable for mass production .
2. Improve product quality: SMT technology avoids the problem of loose socket connections or poor contacts, reducing the failure rate.
3. Improve the reliability of the circuit board: SMT welding method makes the connection points stronger and can withstand greater mechanical stress and vibration.
4. Improve the performance of electronic equipment: SMT technology allows the pin spacing of electronic components to be closer, allowing the manufacture of smaller, lighter products and providing higher integration.
Generally speaking, SMT technology is an advanced electronic component assembly technology and is widely used in the manufacturing process of various electronic equipment.
