Thermally conductive materials electronics

Learn about all Mascherpa’s solutions of thermally conductive materials for the thermal interface of an electronic circuits.

Why do I need a thermal interface material.

Electronic devices create heat, this heat slows down the speed of the device and over time will degrade the component, thus affecting its performance.

With greater miniaturization of systems and higher circuit density, current electronics generate large amounts of heat. This trend, will continue to require the removal of this excess energy, which will be even more critical for future applications. If the heat is not absorbed and dissipated, the life and reliability of the electronics will be reduced.

Heat is transferred from a component to its surroundings. The rate of heat loss will increase with the surface area of the component; a small device producing 10 watts will reach a higher temperature than a device of similar power with a larger surface area.

Heatsinks

Heat sinks can be designed to offer greatly increased surface area to maximize heat dissipation, but nevertheless in order to ensure full contact between the heat sink and the component, only through thermal interface materials will the maximum degree of thermal dissipation be achieved.

Purpose of thermally conductive materials

Metal surfaces, even when thoroughly polished, always show some roughness. Therefore, it can be inferred that when two metal surfaces, such as those between the heat sink and the component are placed together, there will always be small air spaces between the two surfaces.
Thermal interface materials are used in such gaps to fill the air spaces and ensure complete contact between the two surfaces, improving the efficiency of heat transfer.
