Abstract
With the rapid development of electronic technology, the reliability of electronic devices in complex environments has become increasingly prominent, becoming a critical factor that constrains their performance and lifespan. This study aims to thoroughly investigate the design and analysis methods for the reliability of electronic circuits to enhance the stability and adaptability of electronic systems under extreme conditions. Based on modern reliability theory and combined with practical engineering requirements, an integrated reliability design fr amework is proposed, which incorporates Failure Mode and Effects Analysis (FMEA), Accelerated Life Testing (ALT), and multiphysics simulation techniques. This fr amework can effectively evaluate and optimize circuit performance under complex operating conditions such as high temperature, high humidity, and electromagnetic interference. By introducing machine learning algorithms for data mining and prediction of historical records, the accuracy and efficiency of reliability assessment are further improved. Experimental results indicate that the proposed comprehensive design approach significantly reduces the probability of circuit failure and extends its service life. Additionally, this research develops a reliability testing platform tailored for miniaturized and integrated electronic devices, providing strong support for engineering practices in related fields. The primary innovation lies in the integration of intelligent methodologies with traditional reliability analysis, achieving a transition from single-metric evaluation to multidimensional assessment. This not only offers new insights and technical references for the optimization of future electronic circuit designs but also contributes to enhancing the overall reliability of electronic products. The research findings lay a solid foundation for advancing technological progress in relevant industries.
