What is the thermal conductivity test standard for thermal gap pad? How to detect it?

1.What is the main role?

Before understanding the thermal conductivity test standard of thermal conductive silicone pad, let's take a look at its main functions. It is mainly designed to transfer heat through the gaps of electronic products. On the one hand, the gaps can be filled cleverly, so that the heat dissipation area and the heating area can be effectively thermally isolated. On the other hand, because of the special nature of the material, it can also It plays the role of insulation. For more elaborate products, it also meets the design and requirements of the device itself. It is a good choice in terms of technology and use. And the thickness of the product is moderate, the overall practicability is also high, and the range is wide.
                                                                                        
2.What is the thermal conductivity test standard for thermal silicone pad?

As a thermally conductive product, the thermal conductivity is naturally the key to testing. So what is the thermal conductivity test standard for thermally conductive silicone wafers? Thermally conductive pads have been widely used. It also requires reasonable testing before gradually determining whether the product itself Meet the needs of overall production and use. Generally speaking, in the range of the overall ambient temperature of 21-25, the standard for testing the materials and thermal resistance devices through the surface interface is ASTM D5470-2012. The samples are tested under extreme conditions. If the overall range of the coefficient is controlled at 0.8-3.8w / mk, the overall thermal conductivity can be obtained.

3.How to detect the coefficient?

Earlier, I briefly understood the basic standards, and how to detect is naturally one of the concerns of many friends. A more common detection method is to place the price product under thermal stability, so a stable thermal model is used for testing. However, this method requires a higher level of professionalism; if it is tested by yourself, choose the same thickness. Products, under the same environment, according to the same use time, and then check the overall temperature situation; nowadays, the demand for thermally conductive products is increasing, and there are professional testing institutions that can help manufacturers to test the overall product quality or coefficient In order to make suggestions, friends in need can also go to such testing institutions, which can also help in the production of later products.
