Product Series

CMC/CMCC electronic packaging materials

Product Introduction


Copper-molybdenum-copper (CMC) and copper-molybdenum-copper-copper (CMCC) are forms of three-layer materials. The core material is molybdenum or molybdenum copper, with both sides covered with copper. By adjusting the composition of the Cu-Mo core material and the Cu lamination ratio, the thermal conductivity and thermal expansion coefficient of the material can be adjusted. Since the surface consists of copper, it offers an excellent initial heat dissipation performance.

 

Product Application


1. Multi-material electronic packaging materials provide a better alternative for high-power electronic components due to their lower thermal expansion coefficient and thermal conductivity, far superior to WCu and MoCu. They are used to help cool a variety of high-power components such as IGBT modules. Heat sinks, lead frames, expansion layers and heat transfer channels for multi-layer printed circuit boards (PCBs).

2. IGBT modules for electric vehicle engines.

3. High-power RF, microwave and semiconductor devices.
