The low volatility of thermally conductive silicone sheet first creates a clean internal environment for precision electronic equipment. Precision electronic equipment is full of tiny components and fine lines. If the heat dissipation material is easy to volatilize, the volatilized substances may form a thin film on the surface of these components. The low volatility of thermally conductive silicone sheet will hardly release excess substances, avoiding the occurrence of such pollution, keeping the electronic components in a clean working state, and reducing the performance degradation caused by surface pollution.
For optical components in equipment, the protective effect of low volatility is particularly critical. Many precision electronic devices contain optical components such as lenses and sensors. These components have extremely high requirements for surface cleanliness. Even a very small amount of volatiles attached may affect the transmission or sensing accuracy of light. The low volatility of thermally conductive silicone sheet ensures that no volatile substances will fall on the optical components, maintain the clarity and sensitivity of the optical system, and ensure the accuracy of the equipment in imaging, detection and other functions.
Its low volatility helps to maintain the insulation performance inside the equipment. The circuit spacing of precision electronic equipment is extremely small. If the volatiles of the heat dissipation material are conductive, a conductive path may be formed between the circuits, causing a short circuit fault. The low-volatility thermally conductive silicone sheet will not produce such conductive volatiles, avoiding the degradation of insulation performance between circuits, allowing the circuit system of the device to operate stably, and reducing equipment damage or data loss caused by accidental short circuits.
During long-term use, low volatility ensures the stability of device performance. Some electronic devices need to work continuously for thousands or even tens of thousands of hours. If the heat dissipation material gradually evaporates during long-term use, it may change its own thermal conductivity, and the volatiles may slowly corrode surrounding components. The low volatility of thermally conductive silicone sheet makes its performance change very small during long-term use, and will not cause chronic corrosion to surrounding components, allowing the device to maintain a stable working state throughout its service life.
For sealed precision electronic equipment, low volatility solves the problem of internal pressure changes. The internal space of the sealed device is closed. If the heat dissipation material evaporates, it will cause an increase in internal gas and an increase in pressure, which may affect the fixation of the components or cause the sealing cover to deform. The low volatility of thermally conductive silicone sheet hardly increases the internal gas, maintains the pressure stability of the sealed space, avoids the adverse effects of pressure changes on the equipment structure and components, and ensures the long-term reliable operation of the sealed equipment.
Its low volatility can also reduce the corrosion of metal parts inside the equipment. Some volatiles may be corrosive. Long-term contact with metal pins and contacts in the equipment will cause metal oxidation and rust, affecting the conductivity. The low volatility of thermally conductive silicone sheet avoids the generation of such corrosive substances, protects the surface state of metal parts, ensures good contact of circuit connections, and reduces equipment failures caused by poor contact.
In addition, low volatility significantly reduces the maintenance cost of precision electronic equipment. If the heat dissipation material has a lot of volatiles, the equipment may need to be disassembled to clean the attachments on the internal components after a period of use, which not only consumes manpower and material resources, but may also cause damage to the precision components during the disassembly process. The low volatility of thermally conductive silicone sheet greatly reduces the need for such cleaning, and the equipment can keep the interior clean for a long time, reducing the frequency and difficulty of maintenance, and indirectly extending the effective working time of the equipment.
