Approach to the assessment of the storage ability period of electronic components in airborne equipment as applied to the specified model of external impact factors

Annotation: The article deals with challenges arising from the application of electronic components in airborne electronic hardware, which are in the standby / storage mode and de-energized most of the time when not in use, as well they are regularly checked for the proper functioning. The article also discusses some possible solutions to these problems. A technique for assessing storage ability indicators is proposed based on the electronic component properties characterization for the standby / storage mode. The technique is implemented on mathematical models using the activation energy values of the physical-chemical degradation process parameters of the electronic components in airborne equipment. The application of mathematical models addressed to solve the denoted problems can allow author to predict the dependability of electronic products. Some calculations and a comparative analysis of values of all parameters characterized the shortest storage ability period at higher temperature are pre-sented for several groups of electronic components in airborne equipment.
