| Abstract: | The environmental tests were applied to the embedded platinum thermistors Pt1000 according to the industry standard and the national military standard.The environmental reliability of the thermistors was evaluated using the classical method,confidence and Bayes.Based on the problems discovered during the environmental tests,it is shown that the environmental reliability of the thermistors is low and the product quality should be increased by improving the process.Based on the failure analysis of the product... |
