    1、 Basic concepts of thermal interface materials

    Thermal interface material refers to a functional material used to connect two different materials and transfer heat. In electronic devices, thermal interface materials are mainly used to connect chips and heat sinks, or to connect chips and PCB boards to achieve effective heat conduction and dispersion. With the development of electronic devices, the requirements for thermal interface materials are also increasing. They are not only required to have excellent thermal conductivity, but also to have good mechanical properties and stability.

    2、 Classification of thermal interface materials

    Thermal interface materials mainly include thermal conductive silicone grease, thermal conductive gel, thermal conductive gasket, thermal conductive silicone sheet, etc. Among them, thermal conductive silicone grease is a common thermal interface material, which is composed of silicone oil, silicone gel, and fillers, etc. It has excellent thermal conductivity and stability, but is prone to drying and deterioration. Thermal conductive gel is a new type of thermal interface material, which is composed of gel particles and solvents. It has excellent thermal conductivity and mechanical properties, and is easy to use. The thermal conductive gasket and the thermal conductive silicone sheet have good thermal and mechanical properties respectively, but require some manual operation during use.

    3、 The application of thermal interface materials

    Thermal interface materials have a wide range of applications in electronic devices, such as mobile phones, computers, tablets, televisions, etc. In these devices, chips are one of the main sources of heat, and thermal interface materials can effectively transfer the heat generated by chips to heat sinks or PCB boards to maintain the stability and reliability of the equipment. In addition, thermal interface materials also play an important role in fields such as automotive and aerospace, such as connecting automotive engines and transmissions, and connecting aerospace engines and fuselage.

    Thermal interface materials, as functional materials, play an important role in electronic devices. With the continuous development and progress of technology, it is believed that more new thermal interface materials will emerge in the future, providing better support for the development of electronic devices.
