The TFP series thermal pads, with thermal conductivity ranging from 3.5 to 5.1 W/m.K, offer superior thermal performance. Crafted with a special formulation, these pads ensure excellent heat transfer while remaining easy to handle. The material’s natural tackiness ensures strong adhesion to the application area, significantly reducing thermal resistance.
For added convenience during installation and rework, a non-sticky “dry surface” can be created on one side through a unique process. This non-tacky side allows for easy removal from IC chips, PCBs, or other components without causing damage. The tacky side is typically applied to heat sinks, cold plates, or housings, ensuring secure placement and effective heat dissipation.
