The report presented mathematical models for estimating component failure rates and served as the predecessor of what would become the standard and a mandatory requirement for reliability prediction in the decades to come, MIL-HDBK-217. RCA was one of the major manufacturers of electronic tubes (Saleh and Marais, 2006).
The first dossier on reliability prediction was released by Radio Corporation of America (RCA) it was called TR-1100, Reliability Stress Analysis for Electronic Equipment. How do I choose: Telcordia SR-332 or MIL-HDBK-217?, and power supplies, choose to use the Telcordia SR-332 handbook for their reliability predictions.īy Cold War events and the space race, reliability prediction and environmental testing became a full-blown professional discipline (Caruso, 1996). Reliability Prediction Methods for Electronic. This article illustrates how reliability prediction methods for electronic products. By the 1960s, spurred on _ The authors are at the Center for Advanced Life Cycle Engineering at the University of Maryland. This step was the inception of reliability prediction for electronics.
The specification of reliability requirements, in turn, led to a need for a method to estimate reliability before the equipment was built and tested. One of these groups concluded that in order to improve performance, the reliability of the components needed to be verified by testing before full-scale production. These failures led to various studies and the creation of ad hoc groups to identify ways in which the reliability of electronic systems could be improved. Found: User: Sydney.ĭuring this period, electronic tubes were the most failure-prone components used in electronic systems (McLinn, 1990 Denson, 1998). Download a free demo now most commercial electronic product companies are now choosing to use the telcordia sr-332 handbook for their reliability document number telcordia sr-332 issue 3 pdf sr-332, issue 3. HISTORY Attempts to test and quantify the reliability of electronic components began in the 1940s during World War II. Lastly, this paper briefly reviews RIAC 217 Plus and identifies the shortcomings of this methodology. The effect of these shortcomings on the predictions obtained from MIL-HDBK-217 and similar methodologies are then demonstrated through a review of case studies. It then reviews some of the specific details of MIL-HDBK-217 and its progeny and summarizes the major pitfalls of MIL-HDBK-217 and similar approaches. Telcordia Sr-332 HandbookĪnto Peter, Diganta Das, and Michael Pecht This paper begins with a brief history of reliability prediction of electronics and MIL-HDBK-217. This valuable feature comes in especially handy when it is necessary to transfer data from one project or sr-3322 to another. Telcordia SR Telcordia SR was originally the Bell Laboratories Bellcore standard for the reliability prediction of commercial electronic components.
