AMB Ceramic Substrate for Power Modules

Edgetech Industries, Advanced Ceramics Division supplies high-quality AMB Ceramic Substrate for Power Modules at competitive price.


Active Metal Brazing (AMB) Ceramic Substrate for Power Modules

The active metal brazing (AMB) process is a further development of DBC process technology. It utilizes a small amount of active elements contained in the filler metal to react with the ceramic to form a reaction layer that can be wetted by the liquid brazing material, thus realizing the bonding of ceramic and metal.
