Algorithm of Ensuring Accuracy Indicators of Radioelectronic Devices with Consideration of Thermal Modes

In this paper the authors describe an algorithm for ensuring the accuracy of radio electronic devices operating in conditions of extended ambient temperature ranges. A mathematical apparatus for taking into account the coefficients of heat loads on electronic components is presented when analyzing their technological deviations. The purpose of this work is to create an algorithm for calculating the limiting value of the coefficient of heat load, which will provide the specified value of the indicator of the accuracy of radio electronic device in the form of a deviation for the output characteristic. The peculiarity of solving the problem of accuracy in this work is to consider the problems of analyzing the technological deviations on the parameters of electronic components, taking into account the deviations not only on the output electrical characteristics, but also on the temperature of the cases of electronic components.
