Packaging
Description:
They are composites of tungsten and copper. By adjusting the
content of tungsten, we can have its coefficient of thermal
expansion (CTE) designed to match those of materials such as
ceramics (Al2O3, BeO), semiconductors (Si), and metals (Kovar),
etc.
Advantages:
1. High thermal conductivity
2. Excellent hermeticity
3. Excellent flatness, surface finish, and size control
4. Semi-finished or finished (Ni/Au plated) products available
5. Low void
