Thermal Interface Materials |
Electronic devices and systems continue to be designed to run at increasingly higher clock speeds while at the same time being reduced in size. As a result Thermal Management becomes more important to the functionality of a product. To increase heat dissipation between a hot area and the cooling device such as a heat sink, THERMAWORX Thermal Interface Materials are used. These silicone based materials work by displacing the air in uneven areas with highly conductive material yielding increased cooling. Thermal Interface Materials offer excellent thermal transfer properties across a wide gap range, and are available in several formulations for use in a variety of thermal management scenarios.
