Alunit(R) aluminum nitride ceramic substrate from CeramTec offers a thermal expansion coefficient that is comparable to silicon. With its outstanding insulating properties and high thermal conductivity rating (~180 W/mK), the Alunit substrate delivers 10 times more insulating power and heat conductivity than conventional aluminum oxide. It is an ideal substrate for compact, high-density components and hybrids in such applications as power electronics, IGBT modules, telecom components, cooling devices, direct copper bonding and LEDs. The substrate is non-toxic and environmentally compatible, so disposal is never a problem.
