How Thin Is The Thermal Conductive Silicone Pad
Generally speaking, the thinner the thermal conductive silicone pad, the better, so that it can be more useful for conducting heat. However, there is also a limit, it is not possible to reach the thickness of thermal insulating materials or thermal conductive silicone screen printing. SHEEN has received a lot of customer consultations, when asked about the thickness requirements of thermal conductive silicone pad, always said that the thinner the better, there is no specific concept. The following is a real case of the customer choosing the thickness of a thermal conductive silicone pad.
How to choose the thickness of thermal conductive silicone film? Customers need video game handle equipment to use a thermal conductive silicone pad. Ask Sheen how thin a thermal conductive silicone pad can be. Because of the large calorific value of the product, the demand for the heat in the shortest time. The thinner the thermal conductive silica gel pad, the faster the heat transfer, and the minimal impact on the function of the product. The thinnest thermal conductive silicone pad can be 0.3mm, but whether it is easy to use, customers should take into account when planning. The thickness of the thermal conductive silica gel pad is suitable. The puncture resistance of 0.3mm thermal conductive silica gel pad is still very weak. If you take it off from the protective film of PET carelessly, it will tear the thermal conductive silica gel pad briefly. Excessive tension will also constitute product deformation, affecting the equipment after all.
When the customer is withstanding 0.3mm thickness, SHEEN suggests that the customer add 0.03mm glass fiber reinforcement, which can reduce the impact on the product in use, such as tear deformation, and damage. But its disadvantage is the increase of glass fiber cloth, resulting in the increase of thermal resistance of products, thermal conductivity will be relatively poor. Customers are reluctant to hear that adding fiberglass cloth will increase thermal resistance. They say that they should adhere to the product's response sensitivity and generate heat in the shortest time. As a result of customer insistence, we supply a 0.3mm thermal conductive silicone pad.
After a few days of customer feedback, the 0.3mm thermal conductive silicone pad is not very good equipment, the bad rate is too high, easy to deform, and damage, how to deal with it? SHEEN still put forward the previous plan, adding 0.03mm glass fiber cloth to the center of the thermal conductive silica gel pad to reinforce and enhance the tear resistance. Its tensile strength can exceed 100psi. Although increasing glass fiber cloth will increase the thermal resistance a little, from the general function, the overall function of adding glass fiber cloth can still satisfy the use of equipment. We can not simply pursue one of its functions, the best results. It achieves a perfect balance of functionality and operability, which satisfies both thermal conductivity and facilitates construction.
How to choose the thickness of the thermal conductive silicone film? Placing the glass fiber cloth in the center of the thermal conductive silicone film can adhere to the double-sided self-stickiness of the thermal conductive pad. The displacement may be reduced during construction, and the accuracy of the advanced equipment can be improved. The planning of thermal conductive silica gel cushion not only considers the thermal conductivity function but also the balance of thermal and physical functions, insisting on the high reliability and stability of the product.
