CeramTec Alunit® Substrate Offers 10 Times the Thermal Conductivity of Aluminum Oxide



LAURENS, SC - November 30, 2004 - Alunit® aluminum nitride ceramic substrate from CeramTec continues to expand its market share among manufacturers who want dramatically better heat dissipation for their high-power electronic components.

Alunit® 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.

CeramTec produces Alunit® substrates in four surface finishes -- as fired, as fired superior, ground and polished - for both thin-film and thick-film applications. Available manufacturing technologies from CeramTec include tape casting, dry pressing, lasering and metallizing.

A subsidiary of CeramTec AG, CeramTec North America is a leading manufacturer and distributor of custom-engineered, technical ceramics with headquarters in Laurens, SC.
