With the continuous development of science and technology, there are many kinds of materials used in electronic products, and the application range is very wide. Among them, the thermally conductive silica gel sheet is a filler with strong thermal conductivity and good physical inertia, which will not short-circuit the circuit on the circuit board. Thermally conductive silica gel is a material synthesized from silicon and some metal oxides. There are a variety of thermally conductive silicones on the market. Generally speaking, thermally conductive silicone sheets are used in electronic products and medical equipment that require cooling heat. Now there is still a great demand for thermal silica sheets, so how do you use them? How long is the life of thermal silicon wafer?
When it comes to thermal silicon wafers, I believe everyone is familiar with them. At present, it is widely used in the field of heat dissipation of electronic products. Thermally conductive silicon wafers use silicon as the substrate and add various auxiliary materials such as metal oxides. , heat-conducting silicone gaskets, etc., use the design of the gap to transfer heat to complete the heat transfer between the heating part and the cooling part, and at the same time play the role of insulation, shock absorption, sealing, etc., to realize the miniaturization and ultra-thin design of the equipment.

How to use thermal silica gel sheet?
The two sides of the heat-conducting silicone sheet itself have a certain degree of natural adhesiveness, and it is also very convenient to use. At the beginning, make sure that the two bonding places are clean. This allows for a very strong bond between the thermal grease and the adhesive product. This is the same as any other bond. The protective film on the heat-conducting silicone sheet is torn off and then covered on the heat source, and then compacted and pasted.
The steps used by almost all thermal silicon chip products are the same, and this method meets the requirements of fast, simple and easier to use. In addition, according to the size of the place to be glued, the thermal conductive silicone sheet can be appropriately cut.


The life of thermal silica gel sheet:
Generally, it is more than 5 to 10 years, which is based on statistical big data and averaged in combination with the actual situation. In other words, if you can follow the above operating procedure specifications, you can. The thermally conductive silicone sheet also has a certain function of cushioning, vibration reduction and noise reduction, and other normal auxiliary functions. There will be no major problems in about 5 to 10 years.
The service life of the heat-conducting silicone sheet will also vary due to differences in producers, and there will be a certain loss in itself, so the number of years will also change. Affected by these factors, the service life will also be different. Of course, when using thermal silica sheets, there will inevitably be other uncontrollable reasons that affect the life of thermal silica sheets.
Therefore, it is necessary to use the thermally conductive silicon sheet for a long time, carry out reasonable protection, and operate according to the specifications, in order to use the product better, thereby greatly prolonging the use time of the thermally conductive silicon sheet, thereby reducing costs.
