Aluminum nitride sheets are made of high thermally conductive aluminum nitride ceramic, the thermal conductivity is up to 170w/mk, is the highest among all our ceramic materials. Except this, aluminum nitride sheets have similar thermal expansion coefficient with silicon, which will matched perfectly with electronic modules when temperature changes. Adding with the good electrical insulation and dielectric properties, aluminum nitride sheets are ideal material for large scale integrated circuits or high power modules.
