Sammanfattning:
Prediction of reliability is essentially required for
design for reliability, warranty periods, life cycle
costs and maintenance with prior to the installation
of components. Reliability prediction of electronics
advances from an era of military standard books,
Telcordia, PRISM, Bell Core etc. to the physics of
failure approach. Most of the limitations of
constant failure methods are being encounter by
the PoF approach due to its advanced methodology
of finding failure mechanisms by root cause of
failure analysis. But this approach has its own
challenges as it requires detailed information on
materials, process, technology and other
specifications and at most of the times this data is
confidential from the industries. On the other hand,
probability and statistics methods provide
quantitative data with reliability indices from
testing by experimentation and by simulations. In
this paper, qualitative data from PoF approach and
quantitative data from the statistical analysis is
combined to form a modified physics of failure
approach. This methodology overcomes some of
the challenges faced by PoF approach as it involves
detailed analysis of stress factors, data modeling
and prediction. A decision support system is added
to this approach to choose the best option from
different failure data models, failure mechanisms,
failure criteria and other factors.
