GBT ViaTHERM TFP series 3.5 to 5.1W/m.K thermal pads have higher thermal conductivity. With special formulation, pads have excellent thermal performance and are easy to handle. The natural tackiness of the material makes it good contact to the application area, thereby reducing the thermal resistance.
For the special convenience of use and rework, a non-sticky "dry surface" can be formed on one side through a unique process. The thermal pads' non-tacky side can be easily removed from IC chips, PCB or other components without any damage. The other tacky side is usually applied to heat sink/cold plate/housing for heat dissipation.
