First, the number of Electronic Controller Units (ECUs) that are built into contemporary cars has already reached the amount of 100, thus reducing the mean time to failure (MTTF) by the pure quantity of components. Electronic component issues can stem from numerous causes, including product design, manufacturing process, contamination, packaging, storage, or improper handling. This data is then correlated with actual field failures. The portion with the constant failure rate is taken as the life span of the component. The random destructive physical analysis is applied with a view to evaluating the preservation of EC design and process parameters. The time-dependent functions of historical failure rates are typified by parameters of an analytic model that grabs the most important characteristics of these curves. This wrong analysis can be catastrophic in some cases, especially for safety critical systems. In system reliability analysis, one constructs a "System" model from these component models.
