High Thermal Conductivity DBC AlN Ceramic Substrate

The DBC substrate is a metalized substrate in which copper plating is bonded to alumina or aluminum nitride ceramic substrate directly under high temperature sintering to form a film. They are features of high thermal conductivity, high current capacity, and high voltage insulation. DBC ceramic substrate has been proven for ages as a proper solution for electrical insulation and thermal management of high power devices.

The prime advantages of DBC substrates

1. Exceptional hardness, flexural strength, compressive strength and fracture toughness;

2. Great metalization adhesion between copper and ceramic: initial and after thermal cycling;

3. Chemical stability, it won't react with almost acids and alkalis, free of rust forever;
4. High thermal conductivity, the value of AlN DBC ceramic substrate is up to 180W/k.m;
5. High current handling capacity with selection of base layer of cooper;

6. High heat dissipation, it can play a role of heat ceramic sink in the devices.
