High temperature Aluminum nitride ceramic substrate

Aluminum nitride (AIN) is a ceramic material with the main crystal phase, and then etches the metal circuit on the aluminum nitride ceramic substrate, which is the aluminum nitride ceramic substrate. The thermal conductivity of aluminum nitride ceramic substrate is very high, and the heat dissipation and insulation performance are very outstanding. Some high-power devices, modules and other fields have obvious demand

High temperature Aluminum nitride ceramic substrate

It is a high temperature heat resistant material. Thermal expansion system number (4.0-6.0)X10(-6)℃. Polycrystalline AlIN has a thermal conductivity of 260W (m.k), which is 5-8 times higher than that of alumina, so it has good thermal shock resistance and can withstand extreme high temperatures of 2200°C
