An important material for automotive electronic components - the application of dimethyl silicone oil
It is estimated that 85% of all innovations in automotive applications today are electrical or electronic related. As electromechanical is rapidly replacing traditional mechanical and hydraulic functions, and consumers demand new value-added electronic functions, some experts believe that the value content of electronic technology in each vehicle will soon reach an average of 40%, compared with a decade ago. thought it was impossible. Unfortunately, failure rates due to electrical/electronic failures are also on the rise, prompting OEMs and Tier 1 suppliers to adopt demanding reliability standards, leading many manufacturers to seek out new materials and designs to change this trend.
Heat, especially when high humidity and other adverse environmental conditions are also present, often causes components to fail. When temperature fluctuates widely (the most common situation in automotive applications), joints and components experience fatigue caused by thermal expansion and contraction, which can lead to mechanical failure. Metal dendrites can grow in the tight spaces between circuit board traces, eventually leading to short circuits and component failure. It has also been found that the reliability and lifetime of semiconductor devices depend on the junction temperature, and a reduction in temperature of 10-15°C can double the component lifetime.
