Application advantages of silicone gel


Silicone gel is an indispensable part of the application of silicone materials. For example, the encapsulation protection of IGBT originals is the use of silicone gel. The mechanical structure of modern industrial electronic equipment is less and less, and the degree of electrification is greatly improved. Silicon gel can protect sensitive electronic components from moisture erosion and achieve moisture-proof and anticorrosive functions.


The advantage of silicon gel lies in its soft texture and no mechanical stress on electronic components. Even if the temperature is between 50 C below zero and the highest operating temperature of the equipment, its softness will remain unchanged. Specially modified silicon gel can even withstand extreme temperatures between 100 degrees C below zero and 250 degrees C, which is not comparable with other materials. In the extremely high and very low temperature range, hard packaging materials such as epoxy resin will shrink and expand, and ultimately the sensitive electronic components will be damaged by stress changes.


In addition, silicone gel has advantages in processing. Low viscosity silicone rubber can be poured on the surface of PCB. At this point, the silicone gel has the consistency of the gel and adheres firmly to the surface of the circuit board. (the boss of the industry has invented an effective method to compress silicone gel, and the high temperature expansion of silicon gel is now effectively controlled.


Generally speaking, organosilicon gel is widely used as moisture-proof, shock absorbing and insulating coating and potting materials for electronic components. It has dust-proof, moisture-proof, shockproof and insulation protection for electronic components and assemblies. Silicon gel is an ideal coating material for transistors and integrated circuits, which can improve the grid rate and reliability of semiconductor devices. Silicone gel can also be used as an elastic adhesive for optical instruments. The transparent silicone gel can be used to encapsulate electronic components. It can not only play the role of shockproof and waterproof protection, but also can see the components and can detect the malfunction of the components with the probe, and replace the damaged silicon gel.


In the future, the application of silicone gel still has broad prospects.
