Why choose thermal silicone pad as thermal medium for heat dissipation of electronic products?

As the volume of electronic products becomes smaller and smaller, the requirements for heat dissipation of electronic products are getting higher and higher, and among many thermal interface materials, thermally conductive silicone sheet is the most widely used thermal conductive medium, so why electronic products For heat dissipation, should a thermally conductive silicone sheet be selected as the thermal conductive medium?

The demand for thermal conductivity of electronic products is getting higher and higher, which also promotes the development of thermally conductive silicone sheets. At present, the thermal conductivity of thermally conductive silicone sheets on the market can reach 1.0~8.0W/m.k, and the thermal conductivity of thermally conductive silicone sheets can reach 0.05. -k.㎡/W, the hardness can also be adjusted according to the actual situation of the customer’s product. Generally, in the range of 25-50 degrees, the thickness can be 0.3mm-20mm. Various specifications and performance parameters greatly broaden the thermal conductivity of the silicone sheet. The scope of application makes it more widely used.

The benefits of choosing a thermal silicone pad as a thermally conductive medium:

  1. The thermal conductivity of the thermally conductive silicone sheet is very selective and very stable. Customers can choose the appropriate thermally conductive silicone sheet according to the actual needs of their products, which meets the needs of the product without causing unnecessary waste. Compared with thermal conductivity The thermal conductivity of the double-sided adhesive is much more ideal. At present, the thermal conductivity of the thermally conductive double-sided adhesive on the market does not exceed 1W, and the applicability is relatively not so strong.
  2. The thickness and hardness of the thermally conductive silicone sheet can be adjusted according to the actual needs of the product. Therefore, the thermal conduction channel can bridge the dimensional tolerances of the heat dissipation structure and the chip, and reduce the tolerance requirements for the contact surface of the heat dissipation component in the structural design. The thermally conductive silicone sheet The contact area between the heating element and the heat sink can be sufficiently increased, and the production cost can be greatly reduced.
  1. In addition to thermal conductivity, the thermally conductive silicone sheet also has insulating properties and has a good protective effect on EMC. Because the material is a silicone sheet, it is not easy to be pierced and torn or damaged under pressure. EMC reliability is better.
  2. The thermally conductive silicone sheet has good elasticity and compressibility, and has a good shock absorption effect. Adjusting the density and hardness can produce a good absorption effect on low-frequency electromagnetic noise.

A variety of superior properties and extremely wide applicability make thermally conductive silicone sheets an excellent solution for the thermal conductivity of many electronic products. Nuofeng NFION has been focusing on the R&D and production of thermal interface materials for many years. Currently, it can provide various performance parameters for various enterprises. The high-quality thermally conductive silicone sheet, thermally conductive double-sided adhesive, thermally conductive insulating sheet, thermally conductive silicone grease, thermally conductive adhesive, thermally conductive potting glue, thermally conductive gel and other products can meet the thermal conductivity needs of products in different fields!
