Thermal pad is a very commonly used thermal interface filler material. There are various materials in thermal conductivity, but thermal pad has its excellent performance and plays a pivotal role in thermal management. When someone uses it, they will ask, can the thermal pad be used repeatedly? The answer is yes, because the thermal pad has the advantages of high and low temperature resistance, aging resistance, corona resistance, etc., so that the thermal pad can be used repeatedly and has very good results.
In fact, there are still many people who do not know why the thermal pads can be used repeatedly. Today, Nuofeng Electronics will answer the reasons why the thermal pads can be used repeatedly and how to use the thermal pads correctly to achieve the effect of repeated use. !
Analyze the reasons for the repeated use of thermal pads
Why can the thermal silicone pads be used repeatedly? First of all, the thermal silicone pad is a stable solid state, and the thermal silicone pad is not easily destroyed when in use, and such a solid-state film can be easily disassembled when it is installed; that is to say, after you use it once , it can be easily disassembled when you want to use it for the second time. Then the possibility of repeated use is increased. Compared with other thermal double-sided tape or adhesive tapes, thermal silicone pads have great advantages in this regard.
Other thermally conductive materials may not be disassembled after being installed, or may damage the chip or other components during disassembly, and some glues cannot be disassembled, so they must be wiped clean. , so if you want to use it repeatedly, it is better to choose a thermal silicone pads
In addition, the silicone thermal pads has strong compressibility, which makes it elastic recovery, that is, even if the pressure is very high when in use, the silicone thermal pads can also return to its shape. It is worth mentioning that the silicone thermal pads has the advantages of high and low temperature resistance, aging resistance, corona resistance, etc., and has a long service life, so its shape and the material inside will not be destroyed, and it still has stable thermal conductivity. In the next time, the silicone thermal pad is still effective. Therefore, the silicone thermal pad is also very advantageous at this point. For example, some glues are not elastic and cannot be used after one use.
How to use the thermal pads correctly to achieve the effect of repeated use?
But if we want to use the thermal pads repeatedly, we must learn how to use the thermal pads correctly, because the correct method can keep it in its original shape and function. Only if the overall shape of the thermal pads and the material function inside the thermal pads are not damaged, it can be used repeatedly, otherwise it will be ineffective the next time you use it.
First of all, when using the thermal pads, we must keep the contact surface clean, because only cleanness can be easily removed later, and it can also be used repeatedly after the contact surface is removed, so this point one Be sure to pay attention.
In addition, if you use a thermal pad with a relatively large area, you should grab it from the center to ensure that it can be used safely and no other problems will occur. If we want to use the thermal pads repeatedly, we must reduce the number and area of direct contact with the thermal pads, so as to ensure that its viscosity and thermal conductivity will not be damaged. Therefore, we cannot tear off the protective film on both sides at the same time, so as to ensure that the next time it is used, it will be effective.
