Why use thermal silica gel sheet as heat conduction medium

It is well known that electronic products are currently developing towards a smaller and smaller trend, any electronic product is a heating body, which requires a complete set of heat dissipation solutions, and the most important material for these electronic products in the thermal conductivity medium - thermal silicone sheet performance has been constantly improving to meet the increasing requirements of products for heat dissipation.

At present, the thermal conductivity of thermal conductive silicone sheet on the market can be 0.8W-5.0W, compared with the previous years, it is more than 3W thermal conductive silicone sheet to improve a great step, and the thermal thermal resistance of thermal conductive silicone sheet can reach 0.05-k.㎡/W. Hardness can also be adjusted according to the actual situation of the customer's product, generally 10 degrees -50 degrees of this range, the thickness of the thickest can be 15mm, of course, in this case, the thermal conductivity is generally relatively low, generally ultra-high thermal conductivity of the thermal silicone sheet thickness is not more than 5mm.

Thermal conductive silicone sheet mainly has the following advantages:

1 Thermal conductivity of thermal conductive silicone sheet is very selective, and very stable, customers can choose the appropriate thermal conductive silicone sheet according to their actual needs of the product, that is, meet the needs of the product, and will not cause unnecessary waste, relative to the thermal conductivity of double-sided thermal conductive tape to ideal much, the thermal conductivity of double-sided thermal conductive tape on the market is not more than 1W, Applicability is relatively not so strong.

2. The thickness and hardness of the thermal silicone sheet can be adjusted according to the actual needs of the product, so the thermal conductivity channel can bridge the heat dissipation structure, chip and other sizes of the work difference, reduce the structural design of the heat dissipation device contact surface of the work difference requirements, thermal silicone sheet can fully increase the contact area of the heating body and the heat dissipation device, which can greatly reduce the production cost.

3. In addition to thermal conductivity, thermal silicone sheet also has insulation performance, has a good protective effect on EMC, because the material is silicone sheet and is not easy to be pierced and torn or damaged under pressure, EMC reliable performance is better.

4. Thermal conductive silica gel sheet has good elasticity and compressibility, has a good shock absorption effect, and then adjust the density and hardness can produce a good absorption of low-frequency electromagnetic noise.
