Dynamic Reliability Testing about Temperature Characteristic of Components

Lacking of knowing the performance parameters of electrical products can lead to misunderstand the stability of the system. So, it is necessary that use dynamic reliability test to obtain the temperature characteristic of components of new products. Then, two important problems of this testing are selecting sensors and designing testing circuits, and dynamic testing circuit based on temperature sensor AD590 is designed in this paper, and feasibility of the schemes are tested and verified by experiment, which dynamic testing experiment is carried out to U_be of 9014AJ, receive the characteristic curve of temperature through data processing.
