Aluminium brazing - Import export

High Hermeticity Metallized Ceramic Bushing /Innovacera Features: 1.Material: 96% Aluminia(AL2O3) 2.Coating Layer:Molybdenum-Mananese(Mo/Mn) 3.These metallized ceramics are ideal for high voltage, high vacuum and high pressure applicationos. So far the most widely-used and effective method for creating a leak-tight, robust joint between ceramic and metal is by brazing . A thin layer of metal deposited on a ceramic part enables brazing between ceramic and metal part that h as a different coefficient of thermal expansion. A layer of Molybdenum-Manganese is deposited with a typical thickness of 8 to 30 µm after sintering. The metallized surface receives a secondary coating of nickel to seal and improve wettability for later brazing.

AMB (Active Metal Brazing) is for joining ceramics that are not wetted by 'conventional' brazes.By applying active metal like titanium to be added to the braze alloy, to achieve 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 the promising thick film technology which can be applied to Power Electronics, Automotive Electronics, Home Appliances, Aerospace, Others. INNOVACERA provide DBC, DPC, and AMB technology for customized ceramic substrates, welcome to consult more.
