SMT is the abbreviation of Surface Mount Technology. It is a circuit assembly technology that installs surface mount components without pins or with short leads (abbreviated as SMC/SMD, also known as chip components in Chinese) on the surface of a printed circuit board (PCB) or other substrates, and solders and assembles them through methods such as reflow soldering or dip soldering.
The Functions of SMT
Improve production efficiency: SMT uses automated production equipment, which can achieve high-speed and high-precision component mounting, greatly improving production efficiency and shortening the product production cycle.
Reduce the size of electronic products: Surface mount components are small in size and light in weight, enabling more components to be installed on the circuit board of the same area, thus effectively reducing the volume and weight of electronic products and promoting the development of electronic products towards miniaturization and lightness.
Enhance product reliability: Through directly mounting components on the surface of the circuit board, SMT technology reduces the connection points between the pins of traditional through-hole components and the circuit board, reducing the failure rate caused by poor soldering of pins and other reasons, and improving the reliability and stability of products.
Lower production costs: Although the initial investment in SMT equipment is relatively large, in the long run, due to the improvement of production efficiency, the reduction of material costs, and the enhancement of product reliability, the overall production costs can be effectively controlled.
