  • Basic SMT Processing: screen printing (or dispensing), mounting (curing), reflow soldering, cleaning, testing, and repair.



The advantages of SMT surface mount processing include high assembly density, small size and light weight of electronic products, the volume and weight of surface mount components are only about 1/10 of traditional plug-in components, high reliability, strong vibration resistance, and low solder joint defect rate. After using SMT, the volume of electronic products can be reduced by 40% to 60%, and the weight can be reduced by 60% to 80%. PCB SMT has good high-frequency characteristics, reduces electromagnetic and radio frequency interference, is easy to achieve automation, improves production efficiency, and can reduce costs by up to 30% to 50%. Save materials, energy, equipment, manpower, time, etc.
