    Ceramic Substrate

    Alumina ceramic is a kind of structural ceramics,with insulation resistance, voltage resistance, high strength, good thermal conductivity, dielectric loss, stable electrical performance characteristics. Suitable for electronic ceramic substrates, ceramic electrical insulation, vacuum devices, ceramic devices, spark plugs and other products. It can be produced by hot pressing, dry pressing, isostatic pressing, extrusion and other production processes. 96% Alumina Ceramic is commonly used in the electronics industry like thick film circuits, large-scale integrated circuits, hybrid ICS, semiconductor packages, chip resistors, network resistors, focus potentiometers, etc., it is most frequently used ceramic substrates because of its excellent advantages. We can make the part by hot injection pressing, dry pressing, 200T isostatic pressing and extrusion productive technology etc.
