Anomalous and intermittent behaviour is a leading concern for electronics manufacturers of electronic products. Yet it is often not possible to replicate such behaviour, let alone determine the root cause of faults. This paper presents an approach to identify anomalous behaviour using a simple Mahalanobis Distance approach. A case study of experiments conducted on a field returned electronic product is presented.
Index Terms: intermittent behaviour, field returned electronics, anomalous behaviour, Mahalanobis Distance
