Aluminum nitride substrate


Aluminum nitride ceramic thermal plate, high thermal conductivity, low coefficient of expansion, high Strength, high temperature resistance, chemical resistance, high resistivity , low dielectric loss, is the ideal LSI heat dissipation board and packaging materials.Aluminum nitride ceramic plate use heat resistant melt erosion and thermal shock resistance,Can produce GaAs crystal crucible, Al evaporation pan, MHD power generation equipment and highTemperature turbine corrosion resistant parts, using its optical properties can be used as an infrared Window.

Features of ALN substrate

1)High thermal conductivity of more than 170W/m. K,
2)High resistivity,
3)Low dielectric loss,
4)Good insulation,
5)Some other excellent properties
