One of the most important factors defining reliability of radio engineering devices, the temperature is, thus, is the most frequent for calculations of thermal modes mathematical models with the concentrated parameters, possessing low accuracy are used. Now multivariate mathematical models, with a greater degree of ade¬quacy describing processes теплопереноса in radio engineering devices are known. The purpose of the given work is the analysis of reliability of elements of radio engineering devices with application of the modern device of the theory of reliability and methods of multi¬variate mathematical modelling of temperature fields. In the given work comparison of parameters of reliability of the typical electroradioproducts received on the basis of spatial temperature fields and averages on volume of temperatures of electroradioproducts is made.
