SMT surface mount processing requires precision equipment to ensure efficiency and quality. The solder paste printing machine, SMT machine, and reflow soldering furnace are the core equipment, and AOI testing equipment improves quality. Auxiliary equipment such as foot clippers, wave soldering machines, etc. are also indispensable.

1、 Solder paste printing machine
The solder paste printing machine is the starting point of the SMT production line, and its main function is to accurately print solder paste onto the solder pads of the PCB (printed circuit board). Modern solder paste printing machines are usually composed of mechanisms such as plate loading, solder paste addition, embossing, and circuit board feeding. Through precise mechanical and control systems, they ensure the uniform application and precise positioning of solder paste.

2、 SMT machine
Surface mounting machine, also known as surface mounting system, is the core equipment of SMT production line. Its main task is to accurately place surface mounted components onto PCB pads coated with solder paste. The accuracy and speed of the SMT machine directly determine production efficiency and product quality. According to the different installation accuracy and speed, the SMT machine can be divided into two types: high-speed and pan speed to meet different production needs.
3、 Reflow soldering furnace
Reflow soldering furnace plays a crucial role in firmly soldering assembled components and PCBs together in SMT production lines. By precisely controlling the temperature and heating time inside the furnace, the solder paste is melted and cooled to form a reliable electrical connection. The performance of reflow soldering furnaces directly affects the welding quality and product reliability.

4、 AOI detection equipment
With the development of SMT technology, the application of Automatic Optical Inspection (AOI) equipment on production lines is becoming increasingly widespread. AOI equipment can automatically detect welding defects on PCBs, such as misalignment, missing or excessive bonding, and provide timely feedback to operators, thereby effectively improving product quality and production efficiency.

5、 Other auxiliary equipment
In addition to the core equipment mentioned above, SMT surface mount processing also requires a series of auxiliary equipment, such as component trimming machines, wave soldering machines, tin furnaces, washing machines, etc. These devices play an indispensable role in the production process, such as component trimming machines used for processing pin components, wave soldering machines and tin furnaces used for soldering pin components and cables, etc.
