SMT (Surface Mount technology) is a technology widely used in the manufacturing industry to attach small circuit components such as resistors, capacitors, diodes and other components directly to printed circuit boards or other substrates. In some cases, incoming processing of SMT may be used in these locations.

1. Electronic manufacturing: In the production process of electronic equipment, the main use of SMT is to weld a variety of tiny parts to the PCB to form a complete electronic system or product parts. This process is very useful for mass production and automated production lines.

2. Product assembly: For some products that need to be brought to market quickly, efficiency can be greatly improved and costs reduced by using advanced SMT equipment and automated assembly processes. In addition, many consumer product shells also use SMT for connection and decorative processing.
