Product Details

 

CuW75 Chip Carriers, Substrates, Flanges, and Frames For Power Semiconductor Devices
 
Description:
 
W-Cu heat sink material is a composite of tungsten and copper, with both tungsten low expansion characteristics, but also has copper of high thermal conductivity properties, and the tungsten and copper in the thermal expansion coefficient and thermal conductivity can be adjusted with the W-Cu composition, also the composite can be machined to various shape.
 
 
Advantages:
 

High thermal conductivity

Excellent hermeticity

Excellent flatness, surface finish, and size control

Semi-finished or finished (Ni/Au plated) products available
