Basic Process Of Surface Mount Technology

Solder paste printing--> Parts mounting--> Reflow soldering--> AOI optical inspection--> Repair--> Board separation.
Electronic products pursue miniaturization, but the perforated plug-in components used in the past can no longer be reduced. Currently used integrated circuits (ICs) no longer have perforated components, especially large-scale, high-integration ICs, which have to use surface mount components. With mass production and automated production, manufacturers must produce high-quality products at low cost and high output to meet customer needs and enhance market competitiveness. The development of electronic components, the development of integrated circuits (ICs), and the diversified application of semiconductor materials, the electronic technology revolution is imperative. It can be imagined that when the production process of international CPU and image processing device manufacturers such as Intel and AMD has been refined to 20 nanometers, the development of SMT surface assembly technology and processes is also a situation that has to be done.
Advantages of SMT patch processing: high assembly density, small size and light weight of electronic products, the size and weight of patch components are only about 1/10 of traditional plug-in components, high reliability, strong vibration resistance, and low solder joint defect rate. Generally, after adopting SMT, the volume of electronic products can be reduced by 40%~60%, and the weight can be reduced by 60%~80%. SMT patches have good high-frequency characteristics, reduce electromagnetic and radio frequency interference, are easy to automate, improve production efficiency, and can reduce costs by 30%~50%. Save materials, energy, equipment, manpower, time, etc.
It is precisely because of the complexity of the SMT patch processing process that many SMT patch processing factories have emerged, specializing in SMT patch processing. In Shenzhen, thanks to the vigorous development of the electronics industry, SMT patch processing has achieved the prosperity of an industry.
