W90 Tungsten Copper Heat Sink
What is tungsten copper heat sink
The heat sink is the composition of tungsten and copper, which owns the characteristics of both materials. By adjusting the content of tungsten, the coefficient of thermal expansion (CTE) can be designed to match those of materials such as ceramics (Al2O3, BeO), semiconductors (Si), and metals (Kovar), etc.
