How to improve the temperature resistance and earthquake resistance of automotive electronic silicone conductive adhesive

With the increasingly complex structure and working environment of automotive electrical systems, the performance of related materials must also be correspondingly improved. Automotive sensor materials need to have stronger seismic and temperature resistance. Recently, a new silicone conductive adhesive (ECA) has been developed, which can cope with complex and harsh system environments.Research Platinum Series Conductive AdhesiveCapable of withstanding high temperatures of 200 ℃ and strong vibrations.

Conductive silver adhesiveIt is an adhesive with certain conductive properties after curing or drying. It is usually composed of a matrix resin and conductive fillers, namely conductive particles, as the main components. Through the adhesive effect of the matrix resin, the conductive particles are combined together to form a conductive path, achieving the conductive connection of the bonded material. Due to the fact that the base resin of conductive adhesive is a type of adhesive, an appropriate curing temperature can be selected for bonding. At the same time, with the rapid development of miniaturization and miniaturization of electronic components, as well as high-density and highly integrated printed circuit boards, conductive adhesive can be made into a paste to achieve high line resolution. Traditional conductive adhesives use epoxy resin materials for specific sensors. With the advancement of technology, there are more and more sources of heat and vibration in electrical systems, and traditional materials can no longer meet these requirements.

Research on Platinum Organic Silicon Conductive AdhesiveAfter 3000 hours of testing in a thermal shock environment with a temperature of 175 ℃, humidity of 85%, and 3000 cycles of -40 ℃ -175 ℃, the performance was good in both single cycle and long-term operation.

Various automotive electronics manufacturers have different production and application requirements, and the resistance, adhesion, thermal conductivity, and flexibility of ICP4000 conductive adhesive in high temperature and high vibration environments can meet normal working needs. The conductive filler of the conductive adhesive is filled with silver, and the matrix resin is made of thermosetting silicone resin. Compared to traditional epoxy resin materials, it has better flexibility and can automatically compensate for thermal expansion coefficient mismatch, so it can still work normally under extreme high vibration conditions. In addition, the release of irritating gases and residual colloids during the solidification process of platinum conductive adhesive is very minimal, which will not affect the normal operation of surrounding sensors.
