Sinoguide's EMI Thermal Pads

Sinoguide's EMI Thermal Pads are made of silicone rubber combined with fillers to enhance thermal performance and reduce high frequency noise. Thermal mounting pads provide a low thermal resistance path, good thermal performance, and excellent isolation between the electric devices and heatsink. They improve heat conduction by filling air gaps between electric devices and printed circuit boards, heat sinks, or chasses. No thermal greases are necessary.

Metal surfaces, even when polished to a fine degree, have a certain amount of roughness. It can therefore be deduced that when two metal surfaces are placed together contact is not 100% and there will always be an air gap between the two surfaces. The use of a thermal interface material between such gaps ensures complete contact between the two surfaces and in turn more efficient heat conductance.

The electromagnetic waves are absorbed by the pad and changed into heat. The generated heat is conducted through the thermal pad to the heat sink. They are available in single layer and composite layer types. These pads are capable of conforming to irregular or complex surfaces and fill the gaps between heat generating components and heat sinks. Our products are mainly applied in electronic appliances industry, home appliances industry, lighting industry, automobiles industry, photovoltaic industry, mobile phone industry.

They are soft and naturally tacky so they bind tightly to the heat generating device and heat sink for efficient cooling.

They are used in applications including flat cables, LSI and printed circuit boards.
