This presentation intends to address an important gap between reliability test standards and real use conditions of automotive electronic components through a knowledge-based qualification (KBQ) process. With the growth of wide usage of board level electronics in electric and autonomous vehicles, electronic components are exposed to vibration all through their usage life. Relevant vibration-based test standards and field use condition data for this study were chosen and the observed component level failures are analyzed through a physics-based modeling approach. Results from studies show that industry qualification test standards do not adequately reflect the field failure risks.
