In addition to those related to circuits and materials, there are problems such as electronic packaging reliability, heat removal, vibration and noise reduction, stress-concentration avoidance, durability, components life test, etc. all fall in the research contents of mechanical engineering. However, most researchers tend to employ mechanics analyses and/or mechanical tests in their researches. Only a few researchers have combined mechanics analysis with those systematical methods introduced in a typical reliability engineering textbook in their analyses. The purpose of the proposed research is to incorporate reliability engineering into mechanical or mechanics analysis of electronic systems and/or components. To begin with the research, an electronic package subject to drop impulse and/or random excitation will be studied following the routine analytical procedures employed by most researchers. Reliability engineering techniques will be incorporated into the analysis to obtain a randomly distributed life which, in turn, is related to the quantitative reliability of the package. In the second phase of the study, electronic systems or components used or will be installed in vehicles will be studied from a similar point of view. The electronic systems and/or components to be studied can be identified through reliability techniques. After that, both mechanics analysis and reliability analysis will be performed. In the final phase of the study, those electronic systems and/or components used in satellites will be identified and analyzed following similar procedures as above. Special emphases will be put on whether the components satisfy their required test specifications under various environmental conditions. After all, it is the target destination whenever we address the term “electronics reliability.”電子可靠度耐久性環境測試品保壽命力學分析可靠度工程Electronics reliabilitydurabilityenvironmental testingquality assurancelifemechanics analysisreliability engineering
