In recent years, with the rapid development and upgrading of electronic, electrical and digital products, more and more important parts of electronic products are produced towards the trend of miniaturization, and the demand for high-precision processing methods is increasing, as precision welding The new technology of process, laser soldering technology has ushered in rapid development.

Compared with the soldering iron process, the laser welding technology is more advanced, and the heating principle is also different from the former. It is not simply replacing the heating part of the soldering iron. The laser belongs to the "surface heat" and the heating speed is extremely fast.

In addition, in the field of traditional wire welding, the advancement of IC technology, on the other hand, has promoted the development of wire processing technology and technology. For example, in the traditional connector field, the further miniaturization of PCB and terminal size has caused the traditional Hot Bar soldering and electric iron soldering to have process bottlenecks.

In addition, due to the traditional HOT BAR welding and electric soldering iron welding and other contact welding processes, there are hidden dangers of damage to the wire and transmission performance. In the fields that require high wire transmission quality and speed, manufacturers try to avoid using these methods for welding.

At the same time, the emergence of some new MEMS devices, such as mobile phone camera modules, makes the soldering of electronic components get rid of the traditional concept of planar soldering, and is developing towards the direction of three-dimensional soldering. For such devices, contact processing methods such as electric soldering irons are prone to interference.

Non-contact and high-precision processing methods are required. Therefore, more and more people have conducted research on new welding. Among them, laser soldering technology, with its unique heat source properties, extremely fine spot size, and local heating characteristics, helps to solve such problems to a large extent. Therefore, it has also attracted more and more manufacturers' attention.
