But frequently predicted reliability and return rate values by using these methods differ from the field values. The primary reason for this is that products do not only fail due to the stress factors mentioned in the standards and/or used in accelerated life tests. There are additional failure factors such as ESD thermal shocks voltage dips interruptions and variations quality factors etc. These factors should also be considered in some way when predictions are made during the R&D phase. Therefore a method should be used which considers such factors thus increasing the accuracy of the reliability and return rate prediction. In this paper we developed a parameter which we call Robustness Level Factor to incorporate such factors and then we combined this parameter with traditional reliability prediction methods. Specifically the approach takes into account qualitative reliability tests performed during the R&D stage and combines them with life tests by using Artificial Neural Networks (ANN). As a result the approach gives more accurate predictions compared with traditional prediction methods. With this prediction model we believe that analysts can determine the reliability and return rate of their products more accurately.Englishinfo:eu-repo/semantics/closedAccessreliability and return rate estimation, artificial neural networks, defining different failure types, product maturity level, product robustness level, field failures, product level testing, board level testing, design qualityACCELERATED LIFE TESTS, RELIABILITY-PREDICTION, SYSTEM RELIABILITY, MODELSArtificial Neural NetworksProduct Robustness LevelDefining Different Failure TypesDesign QualityProduct Level TestingProduct Maturity LevelReliability and Return Rate EstimationField FailuresBoard Level TestingArticle
