Since entering the field of thermal interface materials, I never thought the thickness of the thermal conductive silicone plate will be a problem. I often hear colleagues and clients to discuss the thickness of thermal conductive silicone plate. Most customers suggested that the price of thermal conductivity of silica gel plate should be accordance with normal thickness. We need to guide the customer to provide accurate thickness. For the importance of silicon sheet thickness of thermal conductivity, thermal conductivity small make up today and share with you the importance of silicon sheet.

1. The thermal conductivity of silicon sheet thickness is very important. The thickness of the thermal conductive silicone plate except with price and the influence of thermal resistance, also directly related to the entire product design tolerance and clearance. Clearance design should consider the size of the product structure, especially when a piece of PCB have N more different function of IC or chips, common is raised and bump, tolerance of each electronic originals or plate is also different. These comprehensive factors determine the thermal conductivity of silica gel plate thickness, this is completely determined by the overall structural design, can not cover any normal thickness.

2. As the interface material, silicon thin film thermal resistance of thermal conductivity is a very important indicator. Value of thermal conductivity of silicon sheet is directly decided the application effect of the thermal conductivity of thermal conductive silicone piece, and the thickness of the thermal conductive silicone piece also directly affects the thermal resistance of thermal conductive silicone piece. Thermal conductivity of silicon sheet thickness is thicker, the greater the thermal resistance of thermal conductive silicone piece, the corresponding thermal effect will surely fall. Therefore, the small make up gives professional advice. The importance of thermal conductive silicon sheet thickness determines the thermal resistance of thermal conductive silicone piece of completely, thus affecting the overall thermal conductivity of thermal conductive silicone. In general, it is suggested that the thickness of the thermal conductive silicone pieces as thin as possible.

3. The thickness of the thermal conductive silicone piece besides related to thermal effect, also is closely related to the thermal conductivity of silicon sheet prices. Thermal conductivity of silicon sheet thickness affect the heat resistance of thermal conductive silicon sheet, it is matter of concern to engineering. The thermal conductive silicone piece is the price of the concern of the buyers. Thermal conductive silicone slice thickness is thicker, the thermal conductivity of silicon sheet price is more expensive, so don't have to be in accordance with the normal thickness when inquiry offer. Even just want to make an inquiry reference, but the thermal conductivity of silicon sheet thickness is different, the price also does not have reference value.
