Polished CMC Block Heat Sink , Heat Spreader / CuMoCu Base Plate For Microwave


Excellent CTE And High TC of Cu/Mo/Cu Heat Spreader For Hermetic Packages



Cu/Mo/Cu(CMC) heat sink, 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.

S-CMC is a multi-layered Copper and Molybdenum clad metal, which has an excellent property both low CTE and high thermal conductivity. Its higher thermal conductivity compared to other same kind of materials contributes to highly powered electronic packages.
