Active Metal Brazing (AMB) Ceramic Substrate for IGBT Modules

The active metal brazing (AMB) process is a further development of DBC process technology. It is a method that uses a small amount of active elements contained in the filler metal to react with ceramics to produce a reaction layer that can be wetted by the liquid solder to connect ceramics and metals. At present, with the rapid development of power electronics technology, high-power device control modules on high-speed rail have created a huge demand for ceramic copper-clad laminates, the key material for IGBT module packaging. In particular, AMB ceramic substrates have gradually become mainstream applications.
