CPS Corp. (Chartley, Mass.) has developed a new version of its AlSiC (Aluminum Silicon Carbide) metal matrix composite material, designed for insulated gate bipolar transistor (IGBT) baseplates for high-power traction, power control and fly-by-wire applications. AlSiC's CTE can be adjusted for specific applications by modifying the Al-metal/SiC-particulate ratio to match the CTE of the die or substrate. The ability to make such adjustments reportedly eliminates the need for thermal interface stacking and ensures IGBT baseplate compatibility with ceramic substrate attachments for high-power applications. AlSiC baseplates are said to survive thousands of cycles without delamination of the substrate from the baseplate. alsic.gocomp.biz/1
