Abstract:
A device for mounting components of electronic circuitry that provides superior thermal conductivity and can survive thermal cycles required for high power or high temperature applications, the device comprising:a ceramic member having first and second major opposed surfaces; a first metal laminate member; and a second metal laminate member, the first and second metal laminate members respectively coupled to the first and second major surfaces of the ceramic member by brazing with a filler material; and wherein each of the first and second metal laminate members comprises a CMC laminate comprising a layer of molybdenum disposed between a first and second layer of copper, the laminates being formed prior to being coupled to the first and second surfaces of the ceramic member and the laminates having a coefficient of thermal expansion approximately equal to coefficient of thermal expansion of the ceramic member.
