High-tech MoCu Electronic Packaging Materials With Silver Plating
Description:
The MoCu composite exhibits combinational properties such as high electrical and thermal conductivities, low CTE, nonmagnetic, good high-temperature performance and etc. Compared with traditional packaging materials, they have a high thermal conductivity and their CTEs can be tailored by adjusting the Mo/Cu ratio to closely match those of die materials.
Compared with WCu materials which also enjoy high thermal conductivity and are CTE changeable, MoCu materials have a lower density.
Advantages:
1. This molybdenum copper carrier/heat sink feature high thermal conductivity and excellent hermeticity.
2. Molybdenum copper carriers are 40% lighter than comparable tungsten copper composite.
