Thermally conductive silicone sheet, with its unique material properties, offers significant advantages in shock absorption and cushioning, effectively protecting delicate components from damage. Precision electronic components are often extremely sensitive to vibration and shock. Even the slightest external force can cause poor contact, structural deformation, or even functional failure. Thermally conductive silicone sheet, through its inherent elastic deformation and energy absorption capabilities, provides a reliable protective barrier for these components.
Thermal conductive silicone sheet's soft and elastic texture is fundamental to its shock absorption and cushioning properties. Using a special silicone base material with excellent flexibility and resilience, thermally conductive silicone sheet elastically deforms when subjected to external shock or vibration, distributing the external force over a larger area and preventing stress concentration that could damage delicate components. This deformability acts like a soft cushion, effectively absorbing and mitigating external vibration energy, reducing impact on delicate internal structures.
In installation applications, thermally conductive silicone sheet can tightly fill gaps between components, minimizing relative movement caused by gaps. There are often tiny gaps between precision components and heat sinks or housings. Vibration during equipment operation can cause friction or collisions between components, which can easily lead to wear or loosening over time. Thermally conductive silicone sheet, under pressure, conforms to the surface contours of different components, eliminating gaps and generating appropriate preload. This creates a stable connection between components, reduces relative motion during vibration, and thus mitigates the risk of damage from friction and collision.
For vibrations of varying frequencies and intensities, thermally conductive silicone sheet can provide shock absorption through its inherent damping properties. Silicone material exhibits a certain degree of internal friction. During vibration, molecular friction within the material converts some of the vibration energy into heat and dissipates it, effectively damping the vibration. This damping effect effectively reduces the transmission efficiency of vibration, significantly reducing the vibration intensity felt by precision components. It is particularly effective in filtering high-frequency vibrations, protecting the microstructures within the components from fatigue damage caused by continuous vibration.
The instantaneous cushioning capability of thermally conductive silicone sheet is particularly important when responding to sudden impacts. When a device is subjected to an unexpected impact, such as a collision or drop, the impact force is rapidly transmitted to internal components, potentially causing serious problems such as loose solder joints and broken circuits. Thermally conductive silicone sheet deforms rapidly upon impact, reducing the peak impact force by prolonging the duration of the force. It also evenly distributes the impact force over a larger contact surface, preventing localized excessive force from damaging delicate components and acting like an airbag.
Its stable physical properties ensure long-term, effective shock absorption and cushioning. Thermally conductive silicone sheet exhibits excellent aging and fatigue resistance. Over long-term use, it maintains its elasticity and cushioning capacity despite temperature fluctuations, humidity, or frequent vibration. Even in complex environments with alternating high and low temperatures, the material's structural stability is maintained, ensuring long-lasting shock absorption and providing long-term, stable protection for delicate components, extending the life of the device.
Furthermore, the sheet's installation method enhances its reliability. It eliminates the need for complex fixing structures and achieves stable installation through adhesive or pressure-bonding, eliminating the vibration transmission issues associated with rigid fastening methods such as screws. This flexible installation method can further isolate the vibration transmission paths between different components, placing precision components in a relatively independent vibration environment, reducing the impact of external vibration sources on them, and improving the overall shock absorption protection effect from the installation structure.
