  Thermal Interface Materials What are Thermal Interface Materials? Successful thermal management of high-power electronic components (single chips, multi-chip modules, integrated circuits, etc.) with high heat dissipation ratings requires careful design engineering. The most important goal in electronic cooling is to maintain junction temperature from rising above prescribed levels. Junction temperature is good predictor of the useful life of the component.  Thermal interface materials bridge the interface between hot components and a chassis or heat sink assembly. Heat transfer is increased, and components are kept cooler. An example is a gap filler pad transferring heat between two or more solid surfaces. How do they work? Materials formulated in the lab are manufactured and inserted between parts to enhance the thermal coupling. Most applications involve dissipating heat. When two surfaces are interfaced, rough surfaces create insulating air gaps between th...
