How to choose the performance parameters of thermal pad?

1. First, determine the thermal conductivity

According to the name of the thermal pad, we can know that in fact, the main function of this material is heat conduction, and the nature of heat conduction is naturally the aspect we focus on when selecting materials. Many people will also choose Don'tt worry about its parameters. In determining the thermal conductivity, the reference factor we generally use is the thermal conductivity. However, it is far from enough to know the existence of this coefficient. The most important thing is to understand what parameters are good Symbol, generally speaking, good parameters are within the range of 0.8w / km -... 3.0w / km. Of course, when choosing, the higher the parameter, the better, and the most important thing is the fit. Otherwise it will cause unnecessary waste.
                                                                                             
2, followed by thickness

Thickness is actually the most easily seen property of thermal conductive silicone pad. As long as the visual inspection generally has a more accurate experience, of course, if you want to obtain more accurate or look at specific data, naturally do not say more about the search for this data. It can be found that the key point is to determine what is appropriate. There are also many factors that affect the thickness. According to traditional ideas, we can judge that in fact, the higher the thickness, the lower the thermal conductivity, but another aspect The thicker the material is, the better the cushioning performance is. When we choose the thickness, we naturally have to make a choice based on these two factors. The focus is on which field is more focused on?

3.The last is the insulation performance

Some thermal pad are insulated, that is, they do not conduct electricity, and others are excellent conductors of electricity. The selection of this performance also requires understanding of specific application scenarios. We use them in the automotive industry. Silicone sheet is mainly thermally conductive, so insulating materials are perfectly acceptable, but if you use it in many electrical fields, the conductive property is very important. If you need to use the thermally conductive property, it also has a conductive material. Good choice.
