85WCu Copper Tungsten Alloy , No Void Heat Spreader For Electronic
Packaging
Description:
Electronic packaging is to put a certain function of the integrated
circuit chips (including semiconductor integrated circuit chips,
thin film integrated circuit substrate, hybrid integrated circuit
chips) placed in a corresponding shell container, which can provide
a stable environment to protect chips work normally and keep stable
functions in integrated circuit. At the same time, encapsulation
also is connection method of outputting and inputting to make the
transition to outside, and it can form a completed entirety with
chips.
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:
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
