In the current era of rapid development of electronic technology, electronic devices are striding towards miniaturization, high - performance, and high - reliability. This development trend has put forward extremely stringent requirements for electronic packaging materials. Silicone rubber, with its excellent and unique properties, has emerged in the emerging field of electronic packaging and has become a key material to support the development of the industry.

The internal space of miniaturized electronic devices is extremely compact, and electronic components are densely arranged. This requires packaging materials to have excellent fluidity and filling properties. In the uncured state, silicone rubber has excellent fluidity and can easily flow into the narrow gaps and tiny holes between components, achieving full - range and 死角 - free filling. In the motherboard packaging of smartphones, silicone rubber can accurately wrap various components such as chips, resistors, and capacitors, effectively avoiding problems such as short - circuits and corrosion caused by the intrusion of air or moisture, and ensuring the stable operation of electronic devices in a limited space.
High - performance electronic devices generate a large amount of heat during operation. If the heat cannot be dissipated in a timely manner, it will seriously affect the performance and lifespan of the devices. Silicone rubber has good thermal conductivity. Some silicone rubbers modified by special filling can significantly increase their thermal conductivity and can efficiently conduct the heat generated by components. In the heat - dissipation module of a computer CPU, the silicone - rubber - based heat - dissipation gasket closely adheres to the CPU and the heat sink, accelerating heat transfer and ensuring that the CPU can maintain stable performance in a high - temperature working environment, avoiding situations such as frequency reduction and system crashes due to overheating.
High - reliability is the core demand of electronic devices. The excellent weather resistance of silicone rubber enables it to maintain stable performance in the face of complex environmental factors such as drastic temperature changes, humidity changes, and ultraviolet irradiation. In the packaging of outdoor electronic devices such as intelligent surveillance cameras and base station communication equipment, silicone rubber can withstand wind, sun, rain, and frost, prevent the internal circuit from being affected by moisture and oxidation, effectively extend the service life of the equipment, and ensure the continuous and stable operation of functions such as communication and monitoring.
In addition, silicone rubber also has excellent electrical insulation properties, which can effectively isolate the current between electronic components, prevent signal interference, and ensure the accuracy and stability of signal transmission in electronic devices. In the packaging of high - frequency electronic devices such as the radio - frequency modules of 5G communication base stations, the low dielectric constant and low dielectric loss characteristics of silicone rubber can greatly reduce the attenuation and distortion during signal transmission, ensuring the high - speed and stable transmission of 5G signals.
