Cuw Base Tosa Package Hermetic Packages Electronics Butterfly Package Receivers Transmitters

W90cu10 W85cu15 Cuw Base Tosa Package Butterfly Package Receivers Transmitters Tunable Lasers


Description:

Tungsten copper heat sink is used for transferring heat generated in microelectronic components to prevent thermal damage.

Tungsten copper heat sink is a composite of tungsten and copper, so both the thermal advantages of copper and the very low expansion characteristics of tungsten can be adjusted to meet different requirements.

The combination of these two materials results in thermal expansion characteristics similar to those of silicone carbide, aluminum oxide, and beryllium oxide, used as chips and substrates.


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 porosity
