基于退化试验的电子产品失效分析技术研究
毕业论文关键词：可靠性； 退化；失效分析 Abstract This topic to grasp and understand the basic principles of electronic product failure analysis technology and related methods, through the design and simulation, improve the beginning ability, ability of problem analysis, judge products meet the requirements to provide corresponding basis, found that electronic products in the technology, design, and all aspects of the defect of raw material, to improve its reliability, improve the mission success rate to provide the corresponding information, is of great significance for the later work and life. Through the analysis of the reliability theory based on performance degradation data architecture, put forward the related concepts, and then according to the principle of different degradation products, the degradation process modeling is performed, based on the relevance of sudden failure rate to describe sudden failure, methods to analyze the failure of competition problems with parameters, thus analysis of the concept of degenerate equation, failure reliability model is established. . Through the electronic product failure analysis technology based on the degradation experiment research, we mastered the degradation rule of aluminum electrolytic capacitor as well as the prediction model is built, and the advantages and disadvantages of different algorithms and related analysis process.
