| Abstract: | A method for estimating the accelerating factors of burn-in tests of spacebrone electronic products is proposed. The proposed method characterizes the effect of temperature on product failure process through the temperature stress parameters in the parts＇ failure rate prediction models. The proposed method estimate the accelerating factors of burn-in tests through comparing the predicted product failure rate under the working temperature with the counterpart under the burn-in temperature. The proposed method is easy for implementation and has clear interpretation. The proposed method can enhance the comparability of the reliability evaluation results with the reliability prediction results. |
