Features: PTM7950 is a super high thermal conductivity phase change material (PCM) in both pad and paste formats. It is designed to minimize thermal resistance at the interface, maintain excellent performance through reliability testing, and provide scalable application at a competitive cost. Based on a dense polymer PCM system, PTM7950 exhibits excellent wettability at the interface over typical operating temperature ranges, resulting in extremely low surface contact resistance. PTM7950 is a proprietary material that provides superior reliability (suitable for 150˚C baking for 1000 hours, T/CB 1000 cycles) and maintains low thermal impedance (<0.04˚Ccm2/W without shim), making the PTM7950 series desirable for high-performance integrated circuits. Product Usage: Clamping pressure and temperature are recommended to achieve a minimum bond line thickness for the thermal interface material, typically less than 1.5 mil (0.038 mm) for best performance. The material must pass the phase change temperature to show justified performance.

During air transport, the cabin and local climate may cause a slight deformation of the product's edge, which does not affect normal use. If unacceptable, please do not purchase. Please allow 1-3 mm error due to manual measurement. Make sure you do not mind this before bidding.
