Cu/Mo/Cu carrier Hermetic Packages Electronics Material CMC Flange
Description:
Cu/Mo/Cu(CMC) carrier, also known as CMC alloy, is a sandwich structured and flat-panel composite material. It uses pure molybdenum as the core material, and is covered with pure copper or dispersion strengthened copper on both sides. Besides, copper molybdenum copper heat sink has adjustable coefficient of thermal expansion, high thermal conductivity, and high thermal stability.
