AI Technology Intros Conformal Thermal Pad
Thermal pad conforms to space between components.
 
Princeton Junction, NJ — AI Technology, Inc. (AIT) has introduced COOL-PAD CPR7154, a new class of thermal interface material that dispenses like a thermal pad, but performs with characteristics like that of a grease or gel when device temperatures increase to above +45°C. The new interface material is optimized to accommodate large areas with different heights and gaps of less than 3-mil along its interfacing area.

The material is filled with a modified oxide mixture and is electrically insulating at normal voltage. It is designed to have high compressibility as applied in comparison to traditional thermal pads.

Once the device temperature reaches +45°C, COOL-PAD CPR7154 will "melt-flow" to fill even the smallest of trapped air along the interface between the device and heat-sink or heat-spreader. The pad is semi-tacky on both sides for optimum thermal transfer performance. It has high thermal conductivity and low Tg characteristics that impose minimum thermal stress on bonded parts during thermal cycling or shock testing. While the pad has some intrinsic tack strength, it is not designed for bonding. A mechanical fastener must be used to provide assembly integrity. A mechanical fastener of 5 psi or more is recommended to provide intimate contact between the COOL-PAD and the interfacing surface. Because the material is compressible, it will fill in uneven height differentials and warps between the mating surfaces. Its ultimate performance is achieved after the first cycle of melt-flow phase-change at +45°C or automatically when the device heats up during operation or with externally applied heat if the device is not anticipated to reach 45°C.

The pad is designed for thermal interface applications to withstand the worst of temperature and moisture exposure in outdoor LED luminaire applications with modules from Philips, Cree, Bridgelux, etc. The same phase-change pad works quite well for CPU and GPU in Xbox360, Play Station, and other game consoles. It is also excellent for CPU modules and graphic card interfaces in laptops and desktop computers.
