WebThe development of the temperature dependence of the reaction rate constant, as it affects reliability, is briefly reviewed. Building on this work, a form for the dependence of the rate constant on nonthermal stresses has been obtained. This form has been used to obtain a thermodynamically consistent form for an acceleration factor that explicitly includes … WebThe Arrhenius-Weibull, Generalised Eyring-Weibull and Inverse Power-Weibull models were obtained and were compared for their effectiveness in to predicting the reliability of LED arrays. AB - This work presents our effort to predict the long term reliability of LED arrays using the application of accelerated life testing principles.
WebHowever, there is significant difference in reliability prediction based on different process. This paper proposes a unified distribution model combined with a stochastic process model in multiple accelerated stress degradation test.
