Why Does The Semiconductor Industry Use Silicone Gel?

Silicone gel is increasingly used in the semiconductor industry, mainly due to its unique physical and chemical properties.

Main advantages of silicone gel

1. Excellent electrical insulation

It has excellent electrical insulation properties, making it an ideal insulating material in the semiconductor industry. This excellent insulation can prevent current leakage, protect circuits from interference, and ensure the normal operation of semiconductor devices.

2. High temperature resistance

Silicone gel has outstanding high temperature resistance and can withstand temperatures up to 250°C (about 482°F) without losing performance.

3. Excellent flexibility

During the operation of semiconductor devices, changes in heat may cause the material to expand or contract. The flexibility of silicone gel enables it to effectively relieve these physical stresses, thereby extending the service life of the device.

4. Excellent waterproofness

It can effectively prevent the penetration of water and moisture, thereby protecting sensitive semiconductor components from environmental influences.

5. Thermal conductivity

Silicone gel can improve its thermal conductivity by adding thermally conductive fillers, effectively helping to dissipate heat.

Application of silicone gel in the semiconductor industry

1. Packaging materials

Silicone gel not only provides excellent electrical insulation protection, but also effectively absorbs mechanical shock and prolongs the service life of the chip. It is widely used in integrated circuits (ICs), LEDs and other electronic components.

2. Heat dissipation management

Heat pads and heat sinks are widely used in these devices to improve heat conduction efficiency and help keep the equipment at a safe operating temperature.

3. Waterproofing and sealing

It is used to seal electronic devices to prevent the intrusion of dust and moisture and protect the internal circuits from the external environment. This application is particularly common in smartphones, home appliances and industrial equipment.

4. Electrical insulation

Silicone gel is used for insulating coatings on cables, connectors and circuit boards to prevent electrical short circuits and failures. Its excellent electrical insulation properties can ensure the safe operation of electrical components and reduce the risk of electrical failures.
