PAKCOOL® PC-7630 combines thermal conductivity and phase change adaptability in one innovative interface material. Upon reaching its phase change temperature (42–52°C), the pad softens, becomes more adhesive, and efficiently fills micro gaps between heat sources and heat sinks—improving heat transfer while preventing leakage or pump-out.

Its self-tacky surface allows for easy placement without additional adhesives, minimizing assembly steps and mechanical stress. Compared with conventional pads, PC-7630 delivers lower thermal resistance and superior heat dissipation at the same pressure.
