A car is a complex product consisting of thousands of parts. Its product reliability is very important. The harsh environment (transportation process, storage, work, climate, etc.) tests the automotive electronic system. For you to sort out the test conditions related to auto parts, as shown in the following table, I hope to give customers a reference. Environmental conditions Main impact Problem with failure high temperature Aging, gasification, cracking, softening, melting, expansion and evaporation Poor insulation, mechanical failure, mechanical stress increase Low temperature Embrittlement, icing, shrinkage and solidification, mechanical strength reduction Poor insulation, cracking mechanical failure, sealing failure High relative humidity Corrosion, electrolysis, insulation insulation effect is worse Poor insulation Low relative humidity Dehydration, embrittlement, reduction of mechanical strength Crack, mechanical failure Low pressure Expansion, air electrical insulation degradation produces corona and ozone, low cooling effect Mechanical failure, seal failure, overheating Corrosive air Corrosion, electrolysis, surface deterioration, increased conductivity, increased contact resistance Wear increases electrical and mechanical failure Rapid temperature change Temperature shock local overheating Crack deformation, mechanical failure Accelerate vibrational damage or impact Mechanical stress fatigue resonance Mechanical failure movable part wear increases structural damage
