Cu-W Heat Spreaders For Use In Cellular Base Stations And Optical Communications
Description:
Copper Tungsten is one of the most popular refractory metal based heat sink materials offered today. With the new off-the-shelf system, we are able to offer standard products with a short lead-time at extremely competitive rates.
Our heat sink 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:
High thermal conductivity
Excellent hermeticity
Excellent flatness, surface finish, and size control
Semi-finished or finished (Ni/Au plated) products available
