The difference between heat conduction pad and heat dissipation graphite sheet

Thermal conductivity pad is basically made of silica gel as the base material and metal oxide as the auxiliary material. The heat conducting material is synthesized by special method. The graphite sheet is generally made of graphite powder. Graphite composite film, made of graphite sheet by coating, coating and other processes heat dissipation.

Heat conduction pads generally use gaps to transfer heat, so the heat conduction between the heat dissipating part and the heat heating part can be completed by filling gaps. The heat dissipation graphite sheet is mainly diffused through the heat source temperature with high thermal conductivity of graphite level, and then conducts heat in the vertical direction.

Thermal conductive pads can generally be made of different thicknesses, which can be adjusted according to the actual application of the product, so there will be a certain degree of compression. It is often used for heat conduction and heat dissipation of electronic components such as electronic IC parts which need to be caulked. The graphite sheet itself is generally ultra-thin. It is often used in high-power and high-heat electronic products such as smartphones, tablets and liquid crystal displays.
