SMT chip refers to the abbreviation of a series of technological processes processed on the basis of PCB. PCB (Printed Circuit Board) is a printed circuit board.

SMT is the surface mounted technology (SMT), which is the most popular technology and process in the electronic assembly industry. The surface mount technology (SMT) of electronic circuits is called surface mount technology or surface mount technology. It is a circuit assembly technology that installs surface mounted components without pins or short leads (SMC/SMD, referred to as chip element device in Chinese) on the surface of printed circuit board (PCB) or other substrates, and then assembles them by reflow soldering or dip soldering.

In general, the electronic products we use are designed by pcb plus various electronic components such as capacitors and resistors according to the designed circuit diagram, so all kinds of electrical appliances need different smt chip processing technologies to process.

Solder paste printing -->part mounting -->reflow soldering -->AOI optical detection -->maintenance -->board splitting.

The electronic products pursue miniaturization, and the previously used perforated plug-in components can no longer be reduced. The functions of electronic products are more complete, and the integrated circuits (ICs) used are no longer equipped with perforated components, especially large-scale and highly integrated ICs, so surface mount components have to be used. With the mass production and automation of production, the manufacturer should produce high-quality products with low cost and high output to meet customer needs and strengthen market competitiveness. The development of electronic components, integrated circuit (IC), and diversified applications of semiconductor materials should be carried out. The revolution of electronic science and technology is imperative and follows the international trend. It can be imagined that when the production process of international cpu and image processing device manufacturers such as intel and amd has improved to more than 20 nanometers, the development of surface assembly technology and process such as smt is also unavoidable.

The advantages of smt chip processing: high assembly density, small electronic product volume and light weight. The volume and weight of the chip components are only about 1/10 of those of traditional plug-in components. Generally, after using SMT, the volume of electronic products is reduced by 40%~60%, and the weight is reduced by 60%~80%. High reliability and strong anti vibration capability. The solder joint defect rate is low. High frequency characteristics are good. Reduce electromagnetic and radio frequency interference. It is easy to realize automation and improve production efficiency. Reduce the cost by 30%~50%. Save materials, energy, equipment, manpower, time, etc.

It is precisely because of the complexity of the process flow of smt chip processing that many smt chip processing factories have emerged, specializing in smt chip processing. In Shenzhen, thanks to the vigorous development of the electronic industry, smt chip processing has achieved the prosperity of an industry.
