IGBT
Base Plates with engineered dome profiles. AlSiC-9 is
chosen for these applications since it supports the bonding of
DBC dielectric ceramic substrates. The product can be
designed with a dome profile for an improved thermal interface
contact with cold plates and coolers.
The
controlled CTE AlSiC value makes it compatible with ceramic substrate
attachment for high power IGBT applications that require high
reliability. AlSiC provides superior reliability performance
surviving multiple thousands of cycles without delamination of the
substrate from the baseplate, as compared to Copper and Aluminum
baseplates[1].
AlSiC baseplates are one third to one fifth the weight of
CuMo or CuW materials (controlled thermal
expansion) baseplates. The compatible controlled thermal
expansion behavior of AlSiC combined with the material being
light-weight make it an ideal material choice for high reliability IGBT
applications such as traction, power control, and fly-by-wire systems.
