PTM7950 Thermal Pad,Laptop Phase Change Silicone Grease Pad Sheet,CPU GPU Thermal Conductive Gasket Patch Features: PTM7950 is a super highly thermally conductive Phase Change Material (PCM) in both pad and formats. It is designed to minimize thermal resistance at interfaces, maintain excellent performance through reliability testing, and provide scalable application at a competitive cost. PTM7950, based on a novel polymer PCM system, exhibits excellent interface wetability during typical operating temperature ranges, resulting in extremely low surface contact resistance. Since PTM7950 comes only in 0.25mm (thicker versions are under development) you need to be sure that this thickness is compatible and suitable for the flatness of your package. PTM7950 is a proprietary material that provides superior reliability (pass 150˚C baking 1000 hours, T/C-B 1000 cycles) and maintains low thermal impedance (<0.04˚Ccm2/W @ no shim), making the PTM7950 series desirable for high performance integrated circuit devices. Product Use：Clamping pressure and temperature are suggested to achieve a minimum bond line thickness of the thermal interface material, typically less than 1.5 mil (0.038mm) for best performance. The material must go through the phase change temperature to exhibit entitlement performance.
