Aluminum Nitride Substrate
Aluminum nitride (AlN) is a advanced technical ceramic material that features an extremely interesting combination of very high thermal conductivity(up to230 W/m.K) and excellent electrical insulation properties. This makes aluminum nitride (AlN) ceramic substrate widely use in power electronics and microelectronics. For example, it is used as a circuit carrier (substrate) in semiconductors or as a heat-sink in LED lighting technology or high-power electronics. Aluminum Nitride(AlN) Ceramic Substrate Advantages ·High thermal conductivity (170-230W/mK), up to 9.5 times than that of Aluminum Oxide ceramic substrate. ·Similar coefficient of thermal expansion to that of silicon (Si), GaN, and GaAs semiconductors. This helps to achieve high reliability of silicon (Si) chip and thermal heat-up cycling. ·High electrical insulation, and smaller dielectric constant. ·High mechanical strength (450MPa). ·Superior corrosion resistance against ...
