AMB Ceramic Substrate is a method to realize the bonding of ceramic and metal by reacting a small amount of active elements Ti and Zr in filler metal with ceramics to form a reaction layer which can be wetted by liquid filler metal.
Advantage:
The combination is achieved by chemical reaction between ceramic and active metal solder paste at high temperature, so its bonding strength is higher and reliability is better.
Disadvantage:
The reliability of AMB process depends largely on the composition of active filler metal, brazing process, brazing layer structure and many other key factors。
