SMT
SMT is abbreviation for Surface Mounting Technology, known as Surface Mounting or Surface Mounting Technology, and is currently the most popular technology and process in the electronic assembly industry.
SMT placement machine mounts chips and components.
It is a surface mount component (SMC/SMD, Chinese called chip component) that is packaged in a matrix arrangement without pins or short leads or balls on the surface of a printed circuit board (Printed Circuit Board, PCB) or On the surface of other substrates, the circuit assembly technology is soldered and assembled by methods such as reflow soldering or dip soldering.
Features of SMT
SMT finished PCBA (Printed Circuit Board Assembly) has high assembly density, small size and light weight: the volume and weight of SMD components are only about 1/10 of those of traditional DIP through-hole components. After using SMT, the volume of electronic products is reduced. 40%~60%, the weight is reduced by 60%~80%;
The quality and performance of SMT welded PCBA are stable: the solder joints are firm and reliable, the anti-vibration ability is strong, and the defect rate of the solder joints is low;
The PCBA welded by SMT has stable electrical properties and low energy consumption: the parts feet and wiring are short, the transmission is fast and the energy consumption is low, electromagnetic and radio frequency interference is reduced, and the high-frequency characteristics are stable and reliable;
SMT is easy to realize automation, improve production efficiency, save materials, energy, equipment, manpower, time, and reduce costs by 30% to 50%.
