Thermal pads and sheets are components specifically designed to manage heat within electronic devices. They act as a conductive medium between a heat source, such as a processor, and a heat sink, facilitating the transfer of thermal energy to help maintain an optimal operating temperature. These materials are soft and malleable, allowing them to conform to uneven surfaces and fill air gaps, ensuring efficient heat conduction. They are particularly useful in spaces where traditional thermal paste application is not feasible or where reusability is a factor, as they can be applied and removed without leaving residue.
The primary uses of thermal pads and sheets include their application in electronics cooling systems for computers, gaming consoles, and various industrial machines where electronic components generate significant heat. Their characteristics, such as thermal conductivity, electrical insulation, resistance to degradation, and various thicknesses, are pivotal in determining their suitability for different situations. High thermal conductivity pads are favored for high-performance components where excessive heat is a concern. Some notable manufacturers of thermal pads and sheets include 3M, T-Global Technology, Henkel, Fujipoly, and Bergquist.
