The Reliability Analysis Center (RAC) has developed a new methodology and associated engineering software tool, PRISM®, to assess the reliability of electronic systems. The methodology includes new component-level reliability prediction models (RACRates) as well as a process for assessing the reliability of systems due to non-component variables which are major contributors to electronic system reliability.

This paper examines two popular prediction methods and compares the results to field data collected on Plastic Encapsulated Microcircuits (PEMs) operating in military, airborne environments.

This evaluation compares the PRISM® predicted failure rate to the actual observed field failure rate for three military electronics units.
