The tradeoff of thermal conductivity of thermal conductive pad: big good or small good?

As a thermal management material widely used in electronic equipment, the thermal conductivity of thermal conductive pad is directly related to the stability and life of equipment operation. Among them, thermal conductivity, as an important index to measure the thermal conductivity of materials, has always been a factor to be considered in the selection of materials. So, is the thermal conductivity of the thermal conductivity of the thermal conductive pad  good or small?

The greater the thermal conductivity of the thermal conductive pad, the faster the heat transfer speed, the better the thermal performance. This feature makes thermal conductive pad with high thermal conductivity have a significant advantage in situations where rapid heat dissipation is required. For example, in electronic devices, thermal conductive pad with high thermal conductivity can more efficiently conduct heat away from the heat source, thus protecting the device from overheating damage.

However, greater thermal conductivity is not always better. On the one hand, thermal conductive pad with high thermal conductivity are often accompanied by higher prices, which increase the cost burden. On the other hand, the thermal resistance of a thermally conductive material is inversely proportional to the thermal conductivity and area, and directly proportional to the thickness of the material. Therefore, in the case of a certain thickness and area, although the higher the thermal conductivity, the smaller the thermal resistance, but the difference in thermal thickness may also lead to high thermal conductivity products but also high thermal resistance. In the selection of thermal conductivity silicone sheet, should be based on the specific application scenarios and needs of the trade-off. If the pursuit of good heat dissipation effect and the cost allows, you can choose high thermal conductivity of thermal conductivity silicone sheet; If there are strict requirements on cost or application scenarios are not particularly high requirements on heat dissipation performance, you can choose products with moderate thermal conductivity and higher cost performance.

To sum up, the thermal conductivity of the thermal conductivity of the silicone sheet is not necessarily good or bad, but needs to be weighed and selected according to specific needs. In the selection, it is recommended to comprehensively consider the thermal conductivity, cost, mobility and application scenarios of the product to find their own thermal conductivity silicone sheet products.
