Hybrid Accelerated Stress Testing and Life Prediction Techniques

Using individual accelerated failure mode tests (such as HALT and FMVT^®) has provided useful information to practitioners in the past. However, the combining of two or more techniques has shown significant improvement at providing fast failure mode information combined with life expectancy and field failure rate information. This paper will give examples of combining accelerated failure mode tests with two or more life prediction techniques to leverage the information gained from the testing. A rationale for how to choose and combine tests will also be discussed.
