Reliability is an issue that we often cannot avoid in the process of electronic product design. For example, customers need us to provide relevant reliability prediction reports, customers need our products to provide corresponding reliability test reports, or the company needs to control the quality of products, and formulates a series of reliability work requirements. It is necessary to carry out various reliability design and analysis work in accordance with the formulated reliability work requirements. In fact, the ultimate goal of implementing these reliability design and analysis work is to solve product reliability engineering problems and strictly control and reduce product quality risks. Since there are many reliability design and analysis tasks, and for designers, these tasks will increase the corresponding workload, how to effectively combine product design with reliability design and analysis work is a problem that designers are very concerned about. Recently, I saw a reliability design and analysis system PosVim. After trying it, I felt that it was quite smooth. Basically, all the reliability design and analysis functions we usually use are included. You can download it for free. This system is divided into four subsystems: design analysis, simulation, testing, and data application. Its functions include reliability prediction (prediction), reliability modeling, FMEA, FTA (fault tree analysis), tolerance analysis (including worst-case simulation analysis, SPICE model), derating design analysis (compatible with ECSS standard and GJB35), reliability allocation, fatigue life analysis (with stress life analysis, tensile life analysis, welded structure fatigue analysis, crack growth life analysis, corrosion fatigue life analysis), failure physics simulation analysis (failure analysis and life analysis of boards and components under thermal, mechanical, and electrical stress), fault diagnosis and life prediction analysis, accelerated life test design and data analysis, accelerated degradation test design analysis, Weibull analysis, and more than 30 other functional modules. There is a download link on the homepage of their official website, which is relatively easy to find.
