Abstract. Spatial modeling of unsteady temperature fields is conducted in a microelectronic printed circuit board (PCB) with an account of convective and radiation heat transfer with the environment. The data for numerical modeling of temperature fields serve as a basis for determining the aging characteristics of the polymer material as a structural component of electronic engineering products. The obtained results allow concluding on the necessity to consider spatial nonuniform temperature fields when estimating the degree of polymeric materials degradation at the continuous service of products, as well as on the impact of polymer aging on reliability features of microelectronic devices.
Abstract.A new forecast approach for the reliability of power semiconductor devices in cyclic operation on the basis of numerical analysis of nonuniform temperature fields is offered. We compared the failure rates of semiconductor power devices in real thermal regime with the thermal conductivity of the statistical data.
