Reliability assessment of electronic units included in complex electronic systems

The aim of this article is to explore the reliability of electronic units, which are parts of complex electronic systems. A failure rates estimation of such units is performed, following a technique based on data for their technical characteristics, such as circuit diagrams, operational regimes and component specifications. A comparison is made of the values obtained with analogous data, valid for electronic units for similar purpose. It is examined the influence of the type of data applied for reliability estimation on the obtained values of units reliability indices estimations, analyzing such kind of units.
