How to choose the ideal thermal conductive silicone pad according to different application fields

Thermal conductivity silica gel sheet, as an effective heat conduction material, has been widely used in many fields because of its excellent thermal conductivity, electrical insulation and soft compressibility. However, different application fields have different requirements for thermal conductivity silica gel sheets. Therefore, when selecting thermal conductivity silica gel sheets, the characteristics and needs of their application fields should be fully considered.

1. Consumer electronics

In smart phones, tablets, laptops and other electronic consumer goods, thermal conductive silica gel sheets are mainly used for heat conduction between CPU, GPU, battery and other heating components and heat sinks. These products have high requirements on the thickness, thermal conductivity and temperature range of thermal conductivity silica gel sheet. Generally, the thermal conductivity silicone sheet with moderate thickness (such as 0.5mm-2mm), high thermal conductivity (such as ≥2.0W/mK) and wide temperature resistance (-40℃ to +200℃) is selected to ensure the stable operation of the equipment and extend the service life.

2. LED lighting field

LED lamps will produce a lot of heat when working. If the heat is not dissipated in time, it will seriously affect the life and light efficiency of LED. Therefore, in the field of LED lighting, thermal conductive silica gel sheet is mainly used for heat conduction between LED lamp beads and heat sinks. In this field, the thermal conductivity and softness of the thermal conductivity silica gel sheet are highly required. Generally, the thermal conductivity coefficient ≥2.5W/mK and the soft and compressible thermal conductivity silica gel sheet are selected to ensure the effective heat dissipation and prolong the service life of LED lamps.

3. Automotive electronics

Automotive electronic systems are sensitive to temperature and the working environment is complex and changeable. Therefore, in the field of automotive electronics, thermal conductive silica gel sheets are mainly used for heat conduction of key components such as engine control units and battery management systems. These components have high requirements on the temperature resistance range, flame retardant and anti-aging performance of thermal conductivity silica gel sheet. Generally choose a wide range of temperature resistance (-40℃ to +200℃), high flame retardant grade (such as UL94V-0), good anti-aging performance of thermal conductivity silica gel sheet, to ensure the safe and stable operation of automotive electronic system.

4. Communication equipment field

Communication equipment will generate a lot of heat during operation. If the heat is not dissipated in time, the performance of the equipment will decline or even fail. Therefore, in the field of communication equipment, thermal conductive silica gel sheets are mainly used for heat conduction of base stations, switches and other equipment. These devices have high requirements on the thermal conductivity, temperature range and electrical insulation performance of thermal conductive silica gel sheets. Generally, thermal conductivity ≥3.0W/mK, wide temperature resistance range (-40℃ to +200℃), good electrical insulation performance of thermal conductivity silica gel sheet is selected to ensure the stable and effective operation of communication equipment.

To sum up, the selection of the ideal thermal conductivity silicone sheet must fully consider the characteristics and needs of its application field. By understanding the performance requirements of thermal conductivity silicone sheets in different fields, we can more accurately select suitable thermal conductivity silicone sheets, so as to ensure the stable operation of the equipment and extend the service life.
