With the development of microelectronic packaging and integrated circuit develops toward miniaturization and micromation, components power improvement, diversification, electrical components to the complicated working environment, put forward higher request to the electrical stability. Silicone is a kind of new high-quality potting material, for its excellent work temperature, weather resistance, heat resistance, insulation performance has become the preferred sealant. In this experiment, through the adjustment of addition-cured silicone composition proportion, effect on the gel properties of components, to find the optimal component ratio. By adding different filler modified silica gel, and study its performance changes, that in aluminum nitride, silicon nitride, boron nitride and titanium dioxide 4 fillers, addition amount in a certain range, can improve the tensile properties of silica gel; adding aluminum nitride, boron nitride can improve the thermal conductivity of silica gel; insulation resistance has little effect on the amount of silica to aluminum nitride, can improve the hardness of silicone. The optimal curing study that the experimental gel for degree is 90 ℃ |
