SMT (Surface Mounted Technology) is the abbreviation for surface assembly technology, referring to a series of processing procedures carried out on the basis of PCB (Printed Circuit Board). The SMT technology originated in the 1960s and has entered a relatively mature stage after several decades of development. The various electronic products we use in our daily lives are obtained by processing on the basis of PCB.

The SMT surface assembly technology installs surface-mounted or short-lead surface-mounted components (referred to as SMC/SMD, also known as chip components) on the surface of the printed circuit board (PCB) or other substrates through reflow soldering for assembly.

Due to the wide variety of electronic components, different SMT soldering and (DIP) insertion processing techniques are required for assembly.

Characteristics of SMT

High assembly density, small size of electronic products: The volume and weight of surface-mounted components are 1/10 of those of traditional plug-in (DIP) components, so compared with traditional plug-in components, the assembly precision of surface-mounted components is higher; the overall weight of electronic products assembled by SMT soldering technology is reduced by 40% to 60%.

High solder joint reliability, low defect rate: The solder joint reliability of SMT processing plants is one of the key factors to ensure the quality of electronic products, and it can effectively reduce the defect rate of solder joints.

Good high-frequency characteristics: It effectively reduces radio frequency and electromagnetic interference.

Easy to achieve automation and improve production efficiency: The SMT soldering technology simplifies the production process of electronic complete products, is easy to achieve automated production, and greatly improves production efficiency, thereby reducing 30%-50% of labor, time, energy and other costs.

In summary, in the face of the rapidly developing electronic industry, adopting SMT technology not only enables enterprises to better adapt to current market demands and improve product market competitiveness, but also helps enterprises reduce costs and increase efficiency.
