The Chomerics Division of Parker Hannifin has launched a thermally conductive gap filler pad to boost the thermal performance of devices.
The THERM-A-GAP PAD 70TP offers the combination of both excellent thermal conductivity (7.0 W/m-K) and ultra-soft conformability, along with very low outgassing. The result is an effective thermal interface between heat sinks and electronic devices, even where uneven surfaces, air gaps or rough surface textures exist. Thermal Paste For Lithium Battery
The pad provides higher thermal performance and long-term stability than conventional thermal pads and is aimed at applications from telecommunications equipment and PC boards to chassis applications, thermally enhanced BGAs (ball grid arrays), memory packages and modules, GPU and CPU applications, and a host of industrial devices.
These applications and many more will benefit from the excellent thermal properties of THERM-A-GAP PAD 70TP, which include 0.27°C-in/w thermal impedance (at 10psi, 1mm thickness) and 0.72J/g-K heat capacity.
The product also has 1013 ohm-cm volume resistivity, in addition to low deflection force and low oil bleeding. The latter is particularly important as it minimises the generation of greasy substances on the surface of the heat sink or substrate during use. Oil bleed from comparable products in the market can lead to lower electrical performance in the shape of reduced surface resistance and breakdown voltage. In addition, surrounding impurities and particles may adsorb in or adhere to the oil, threatening product performance and lifespan.
Parker Chomerics manufactures THERM-A-GAP PAD 70TP to size, facilitating easy application on the desired component. A fabric carrier version is available for improved tear resistance and easy handling. Suitable for use in a wide operating temperature range from -55 to +200°C, the new RoHS-compliant gap filler pads are available in standard thicknesses from 0.76 to 5.0mm.
