SMT production line is a new generation of electronic assembly technology developed from hybrid integrated circuit technology, characterized by the use of component surface mount technology and reflow soldering technology, becoming a new generation of assembly technology in electronic product manufacturing. The main components of an SMT production line include surface mount components, circuit substrates, assembly design, and assembly processes.

With the development of surface mount technology, the pin spacing of devices continues to decrease. Due to various reasons, some small components often have defects such as solder joints, bridging, offset, solder balls, poor soldering, and pin deformation. Using traditional microscopes, only static images of the plane can be seen, making it difficult to clearly determine whether the cracks at the solder joints are real or reflected by the light source.

It can observe the situation of PCB holes, the side of IC pins, and the climb of solder at the root of pins from the side, discover various welding defects, and make correct judgments easily.

Three dimensional viewfrequentMicroscopes can be used in many different departmentsBy inspecting and analyzing the internal and external quality of SMT welding in various situations, its selection can comprehensively control the quality of SMT welding and improve the product's straight through rate
