Solder paste printing --> parts placement --> reflow soldering --> AOI optical inspection --> maintenance --> sub-board.
Electronic products are pursuing miniaturization, and the previously used perforated plug-in components can no longer be reduced. Electronic products have more complete functions, and the integrated circuits (ICs) used have no perforated components, especially large-scale, highly integrated ICs, which have to use surface mount components. With mass production of products and automation of production, the factory must produce high-quality products with low cost and high output to meet customer needs and strengthen market competitiveness. The development of electronic components, the development of integrated circuits (IC), and the diversified application of semiconductor materials. The revolution of electronic technology is imperative and chasing the international trend. It is conceivable that when the production processes of international cpu and image processing device manufacturers such as intel and amd have advanced to more than 20 nanometers, the development of smt, such as surface assembly technology and process, is not a case.
The advantages of smt chip processing: high assembly density, small size and light weight of electronic products. The volume and weight of chip components are only about 1/10 of that of traditional plug-in components. Generally, after SMT is adopted, the volume of electronic products is reduced by 40%~60 %, the weight is reduced by 60%~80%. High reliability and strong anti-vibration ability. The defect rate of solder joints is low. Good high frequency characteristics. Reduce electromagnetic and radio frequency interference. It is easy to realize automation and improve production efficiency. Reduce costs by 30%~50%. Save materials, energy, equipment, manpower, time, etc.
It is precisely because of the complexity of the process flow of smt patch processing that there have been many smt patch processing factories that specialize in smt patch processing. In Shenzhen, thanks to the vigorous development of the electronics industry, smt patch processing achievements The prosperity of an industry.
