AMB (Active Metal Brazing) is for joining ceramics that are not wetted by ‘conventional’ brazes.
Applying active metal like titanium is added to the braze alloy, to achieve a chemically reacts with the surface of the parent ceramic.
Due to the coefficient of thermal expansion of Al2O3 (7.1 ppm/K), Si3N4 (2.6 ppm/K), and AlN (4.7 ppm/K) is close to that of silicon (4 ppm/K), Direct Bond Copper (DBC) and AMB are suitable substrates for robust packaging of bare dice since such assemblies.
AMB is a promising thick film technology that can be applied to Power Electronics, Automotive Electronics, Home Appliances, Aerospace, and Others.
