An integrated method for hardware FMEA of new electronic products

Abstract

Failure mode, effects analysis (FMEA) is widely recognized and applied in different fields, such as aviation, aerospace, automotive industries. And later FMEA has been extended to other industries, such as electronics, medical and so on. For key products, FMEA is an indispensable part in reliability analysis. However, many products are newly researched and developed, with high integrated level and complicated failure mode, reasons and effects. Historical data and similar products data are also scarce, which constrain the effectiveness of hardware FMEA. Besides, technicians are relatively young and inexperienced with incomplete understanding of failure and effects, which will result in incomplete analysis results. These problems affect implementation effect of hardware FMEA and will affect the subsequent reliability, maintainability, testability and supportability analysis work. Aiming at the above problems, this paper proposes an integrated method for hardware FMEA of new electronic products which integrates present advanced failure mode acquisition, failure mechanism analysis and failure effect analysis together. This method can effectively solve the above problems, meanwhile make supplement for the problem not taking redundant design into consideration in traditional FMEA method. It has been proved that this integrated method achieved good effect on a type of new research aviation electronic products.
