Using samples for reflow testing is already a mature method to determine whether laser reflow is suitable for the product and the process parameters that must be controlled in order to achieve the desired solder joint quality. It is one thing to study how the laser works in theory, but it is another thing to apply in practice. If the reflow of solder paste on a p...

Since the first GaAs semiconductor laser in the world came out in 1962, it has a history of more than 50 years. Now semiconductor lasers have been widely used in laser communications, optical disk storage, laser detection and other fields. 　　 With the continuous improvement of the continuous output power of semiconductor lasers, its application range is also expanding. ...

The IGBT module is a new generation of power semiconductor electronic component modules. It was born in the 1980s and carried out a new round of reforms and upgrades in the 1990s. Through the development of new technologies, the current IGBT modules have become integrated Fast speed, high voltage, low loss, high current thermal stability, and many other features are comb...
