SMT surface mount processing is the process of processing PCB bare boards and mounting electronic components onto the PCB board. This is a popular electronic processing technology nowadays, as electronic components are becoming smaller and there is a trend towards gradually replacing DIP plug-in technology. The SMT surface mount processing process can be divided into pre process and in process.

Before starting SMT surface mount processing, various PCB file materials, circuit board information (Gerber), material list (BOM), and auxiliary materials need to be prepared. These are the foundation of SMT surface mount processing. After the preparation work is fully completed, SMT surface mount processing can be carried out.
