How to Choose Thermal Silicone Pad? Sheen Helps You Solve the Selection Problem
Knowledge point 1: thermal silicone pad is one of the structures of technology products (for enterprises, the enterprise itself does not regard thermal silica film as part of its own products, so the appearance, function and heat dissipation issues considered at the beginning of product design, etc. The thermal silica sheet is not included in the product itself, the design of the product determines the appearance, thickness, hardness and related parameters of the thermal silica sheet).
Knowledge point 2: Selection of performance and appearance of Thermal silicone pad (after the product design plan is determined, the choice of performance and appearance. Performance includes thermal conductivity, thermal resistance, hardness, deformation, etc., product gap determines the thickness of thermal silica gel sheet, selection At the same time thickness, hardness and deformation should be basically confirmed; the power and cooling range of the product determine the thermal conductivity and thermal resistance of the thermally conductive silicone sheet, and of course also depend on the company's cost requirements. According to the actual situation, just choose the company's own suitable specifications. Appearance Including thickness, shape, color, etc. the selection of specific key features depends on the design scheme).
Knowledge point 3: Other related issues - breakdown voltage, oil yield, fire performance (generally, the breakdown voltage and fire performance of Thermal silicone pad can be satisfied, what needs to be paid attention to is the oil yield High rate, the composition of the Thermal silicone pad contains silicone oil, which is easy to volatilize under high temperature or long working time, causing pollution or short circuit to the product, so the oil output rate is generally recommended to be within 200PPM, and non-silicon thermal conductive silicone can be selected if there are special requirements piece).
