Phase change interface material
BC phase change interface material
The material is heat reinforced polymer, designed to meet the thermal conductivity and reliability demand for the
thermal conductivity of high application terminal. In addition, the heat sink’s performance benefits a lot from the
low heat resistance. And improve the microprocessor, DC -DC converter of memory module and the reliability
of power module.
The phase change characteristics: the material is solid in room temperature and installation is completely convenient,
used between heat sink and devices. The material can be softened and flowing when the products reach phase-change temperature to fill the devices’ tiny irregular contact surface. Thus, the material has the ability to fill the gap
between the devices and heat sink completely, make the phase change better than non-current elastomers or thermal
graphite pad and get the performance of thermal conductive silicon grease.
The material is nonconductive, however, as the material has endured the phase change at high temperature, may make
the metal get to the metal, so the phase change interface material can not be used as electrical insulating material.
Features & benefits:
-Low heat resistance und low stress -Flowing but not silicone oil -No radiator preheating
-Low volatility—less than 1% -Self-adhesive , easy to use
Typical applications:
-High frequency microprocessors -Bridge rectifiers -Graphics chips & Amplifiers chip
-Chipset -Cache memory chips
