PCB Technical - How to save materials in Wuxi SMD processing

Wuxi SMD processing is a more popular processing technology in the current electronic assembly industry. With the continuous development of electronic technology, the importance of SMD processing is also emerging. Its patch processing mainly refers to the placement of components on the PCB board printed with solder paste through the placement equipment, and then soldering and other operations. As a result, electronic products are small in size and stable in performance, so they are widely loved. In addition, the stable work efficiency and performance of the placement machine also bring greater advantages to production. Here are some basic introductions about placement processing.

SMT patch refers to the abbreviation of a series of technological processes that are processed on the basis of PCB. PCB is a printed circuit board. SMT is a surface mount technology (surface mount technology), which is a popular technology and process in the electronics assembly industry. Electronic circuit surface assembly technology is called surface mount or surface mount technology. It is a kind of surface assembly components with no leads or short leads (SMC/SMD for short, chip components in Chinese) mounted on the surface of a printed circuit board or other substrates, through reflow soldering or dip soldering, etc. Method to weld and assemble the circuit assembly technology. Under normal circumstances, the electronic products we use are designed by PCB plus various capacitors, resistors and other electronic components according to the designed circuit diagram, so all kinds of electrical appliances need a variety of different SMT chip processing techniques to process.

Wuxi SMD processing

High assembly density, small size and light weight of electronic products. The volume and weight of SMD components are only about 1/10 of traditional plug-in components. Generally, after SMT is adopted, the volume of electronic products is reduced by 40%~60%, and 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. 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, and surface mount components have to be used. 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 multiple applications of semiconductor materials. The revolution of electronic technology is imperative and chasing the international trend.

In practice, the environmental requirements of the production workshop are relatively high when the Wuxi SMD processing is carried out, because temperature, humidity, cleanliness, etc. will have a certain impact on the product. After the chip is processed, the volume of the component can be effectively reduced by 40% to 60%, and its weight can be reduced by 60% to 80%, which greatly saves materials and energy. With the development of social science and technology, the degree of automation has become higher and higher, and patch processing can automate products and production, adding luster to the PCB industry.
