Thermal Interface Material

Thermal interfacial materials (TIMs) are thermally conductive materials, which are applied to increase Thermal contact conductance across jointed solid surfaces, such as between microprocessors and heatsinks, in order to increase thermal transfer efficiency. These gaps are normally filled with air which is a very poor conductor.

They take many forms. The most common is the white-colored paste or thermal grease, typically silicone oil filled with aluminum oxide, zinc oxide, or boron nitride. Some brands of thermal interfaces use micronized or pulverized silver.

Another type of TIM are the phase-change materials. These are solid at room temperature but liquefy and behave like grease at operating temperatures. They are easy to handle and are not messy.

Famous quotes containing the word material:

    We have not the slightest idea that women are made of such light material that the breath of any fool or knave may blow them on the rocks of ruin.
    Jane Grey Swisshelm (1815–1884)
