Aluminum nitride ceramics are high thermal conductivity ceramics,which have a coefficient of thermal expansion close to that of silicon, good insulation properties, moderate dielectric constant and dielectric loss, room temperature and high temperature mechanical properties and non-toxic and other excellent characteristics, as integrated circuits and high-power devices, substrate materials and electronic packaging materials have a broad application prospects.
Characteristics of ALN ceramics:
1. Excellent thermal conductivity, with theoretical thermal conductivity of 320W/m.K, 7~10 times that of aluminum oxide, and equivalent to metal copper and aluminum
2. Excellent mechanical properties, which are equivalent to Al2O3 ceramics
3. Excellent insulation performance, greater than 15KV/cm
4. Thermal expansion coefficient matched with silicon and SiC
5. Non-toxic
6. Good thermal shock resistance
7. Resistance to plasma intrusion
