When conducting business exchanges and return visits with customers recently, many customers and friends mentioned the use and life of thermal pads. How often do they need to be replaced?
The thermal silicone pad is an indispensable thermal conductive material in the design of the heat dissipation module of many electronic products, but the thermal conductivity of the thermal pads gradually decrease under the continuous use for a long time. So, does the thermal pad need to be replaced? How often does it need to be replaced?
The answer is that it needs to be replaced. So, how long does it take for the thermal pads to be replaced?
The thermal pad is excellent in both its performance and service life. Unlike the volatilization and aging of silicone grease, the service life of the thermal pads can generally be as long as ten years, so this is also the reason why the thermal pads can be widely used. important reason.
Each company’s products are different, the production process and technical standards are different, the quality of raw materials is different, and the level of technological development is different, which will affect the life of the thermal pads. Therefore, the frequency of replacement of the thermal pad is different. Generally speaking, the service life of the thermal pad is generally 5~8 years. After 5 years, some characteristics of the thermal pads material itself, such as thermal resistance, thermal conductivity, voltage resistance, etc., will be affected, plus the thermal conductivity of the thermal pads material itself. Aging accelerates the aging of the product.
Although thermal pads has a long service life, it is generally recommended to replace the thermal pads after five years. Because the thermal pad is used for a long time, its own thermal conductivity, thermal resistance and other properties will decline, and there will be phenomena such as material aging, which will make the thermal conductivity and performance not as good as before. Moreover, the difference in material selection and overall production process of thermal pads produced by different manufacturers results in different service life of the thermal pads. Therefore, it is generally recommended to replace the thermal pads in advance.
Moreover, the way the thermal pad is used will affect its service life. Unsuitable environment and installation will easily cause it to oxidize, dry and turn black after long-term use. Once the thermal pads has the above conditions, it will affect it. The thermal conductivity needs to be replaced in time.
Generally, it is no problem to use thermal pads with good quality for more than 5~8 years. Therefore, it is a reasonable cycle to replace them once every five years. In the process of purchasing thermal pads, try to choose big brand manufacturers. A large thermal interface material brand manufacturer, currently able to provide a variety of high-quality types of thermal pads!
With more than 10 years of experience in R&D, production and sales of thermally conductive materials, CoolThermo thermal pads has greatly improved the service life and reliability of the material, which has far exceeded the industry standard by 3-5 years. At present, the materials supplied in batches are delivered to customers in batches in strict accordance with the standards of the automotive industry. Moreover, the construction and disassembly are also very convenient. After removing the thermal pads, wipe the surface clean, directly attach a thermal pads of the same size, and fix it with screws or fasteners. Very simple, convenient and easy to operate and construct.
