Thermal Interface Pads Provide Low Thermal
MH&W International announced Keratherm 86/82, a high tensile strength, thermal interface material (TIM) that improves heat transfer from ICs and other components to their heat sinks, and provides durability for installation and long-term use. It is a thermally conductive, electrically isolating silicone film with a reinforcing fiberglass layer for tear and cut-through resistance. The silicone provides excellent wetting properties for filling interface surfaces. Thermal impedance is 0.05 W/mK, and thermal conductivity is 6.5 W/m-K. With its fiberglass layer, 86/22 has a tensile strength of 20 N/mm2. The material meets UL 94V-0 flameclass requirements, and its continuous use temperature range is -40°C to +200°C. It is available in kiss-cut shapes on continuous rolls for easy peel-and-place installation. The fiberglass layer allows safe, easy removal and reapplication of 86/22 pads, and adds durability for long-term performance. Pads of 86/82 are inherently tacky and will stick to heat sinks during assembly. An optional adhesive coating allows permanent attachment. They are available in a wide range of standard or custom configurations. Standard material thickness is 0.250 mm (9.8 mil), and pads are also available in 0.300 mm, 0.400 mm and 0.500 mm thicknesses (11.8, 15.7, and 19.6 mil). Volume pricing starts at $0.30 per square inch for standard 86/22 material.
