In the Aspect of Integrated Circuit Packaging
Protecting Chips from the Environment: In integrated circuits such as the central processing units (CPUs) of computers, packaging materials based on organic silicone resins are often used. Chip manufacturing companies like Intel utilize the excellent electrical insulation, high - temperature resistance, and low coefficient of thermal expansion of organic silicone resins to encapsulate chips, protecting them from external moisture, dust, and chemical substances, and ensuring the stable operation of chips in complex usage environments.
Improving Heat Dissipation Performance: Some high - end graphics card chips of NVIDIA also adopt organic silicone composite materials for packaging. Their low coefficient of thermal expansion can reduce thermal stress, and they have certain thermal conductivity, which can quickly conduct the heat generated by the chip, improving the thermal stability and reliability of the chip. This ensures that the graphics card will not experience performance degradation or malfunctions due to overheating during high - load operation.
In the Aspect of Electronic Component Packaging
Packaging of Resistors, Capacitors, etc.: On the circuit boards of various electronic devices, components such as resistors and capacitors are often packaged with organic silicone resins. For example, some high - precision capacitors produced by Murata Manufacturing Co., Ltd. use organic silicone resin packaging, which provides a stable electrical insulation environment for the capacitors, prevents electrical interference between components, and protects the components from mechanical shock and vibration, thus extending their service life.
Sensor Packaging: In the tire pressure sensors of automobiles, organic silicone resins are used to package the sensor chips. It can withstand the high and low temperature changes during the vehicle's driving, protect the sensors from external moisture, oil, etc., and ensure that the sensors accurately measure the tire pressure and transmit data.
In the Aspect of Flexible Circuit Board Packaging
Flexible Circuit Boards in Mobile Phones: In the flexible circuit boards of some high - end smartphones such as those of Apple, organic silicone resins are coated for packaging. Organic silicone resins provide good electrical insulation and mechanical protection, ensuring that the circuit board will not experience problems such as short - circuits or open - circuits during frequent bending and twisting in mobile phone use, and improving the flexibility and durability of the circuit board.
Flexible Circuits in Wearable Devices: In wearable devices such as smart watches and bracelets, flexible circuit boards encapsulated with organic silicone resins are widely used. For example, in some smart watches of Huawei, the internal flexible circuit boards use organic silicone resin packaging, enabling the circuit boards to adapt to the movement and bending of the wrist. At the same time, they have good temperature resistance and chemical corrosion resistance, ensuring the reliability of the device.
In the Aspect of Optoelectronic Device Packaging
LED Packaging: In the lighting field, high - brightness LED lamp beads produced by companies such as OSRAM often use organic silicone resins for packaging. Organic silicone resins have excellent optical transparency, which can ensure the light output efficiency of LEDs. At the same time, they protect the LED chips from the external environment, improving the stability and service life of LEDs.
Laser Device Packaging: Laser - emitting devices in optical fiber communication also use organic silicone resin packaging. For example, some optical communication laser devices of FiberHome use organic silicone resin packaging to provide good electrical insulation and heat dissipation performance for the laser devices, ensuring the stability and reliability of the laser devices during high - power operation.
Other Aspects
Memory Module Fixing Strap: Apacer's strong - fixing strap for DRAM modules in edge AI hardware uses polysiloxane (a type of organic silicone resin) material. This fixing strap has high elasticity and flexibility, can withstand low temperatures and high temperatures of 200°C, and is completely insulated, eliminating the risk of PCB short - circuits. It can effectively fix the DRAM module to the corresponding DIMM slot.
Adhesive Layer of Printed Circuit Boards: The patent of "Fine - line Printed Circuit Board and Preparation Method" by Beijing Xingfei Electronics Co., Ltd. introduces an organic silicone resin adhesive layer as an intermediate layer between the substrate and the base copper, effectively improving the bonding force between the glass - cloth resin - based substrate and the chemical copper, and optimizing the stability of the circuit board.
