The application of fault tree analysis method in electrical component

摘要

Fault tree analysis is a method which is widely used in analysis and forecasting system security and reliability. This analysis method is also applicable for reliability analysis of components. It is first time in domestic to apply FTA techniques to electronic components in this paper. It also introduced the fault tree analysis method for electronic components in detail, including fault tree artificial construction method, qualitative analysis and quantitative analysis methods, which took the failure mode “short” for semiconductor device as an example. According to fault tree analysis for electronic components, it can identify possible failure causes, analyze the major failure causes and present corresponding measures to prevent component failure.
