Aluminum Nitride Ceramics

The thermal conductivity of AlN ceramic sheet is 180W / m.k, which is 7-10 times of that of alumina ceramic. Excellent mechanical properties, good machinability, high dimensional accuracy, smooth surface, no micro cracks, bending and so on. Low dielectric constant and dielectric loss, reliable electrical insulation performance. It is nontoxic, 1800 ℃ resistant, oil resistant, chemical resistant, and has the same coeffiffifficient of thermal expansion as silicon, no hygroscopicity, and stable performance under high temperature and high humidity conditions. With the wide development of microelectronic equipment, high thermal conductivity AlN ceramic chip as a matrix material or packaging material has been widely valued and applied.
