In recent years prognostics and health management has become the preferred approach to achieve advance warning of and respond to impending failure of systems. One approach for conducting prognosis is to use a canary device which fails by the same failure mechanism as would the actual product. The canary device is designed to fail before the actual product. This paper presents a novel method of using solder interconnection as a canary. The application of the approach for prognosis of Ball Grid Array packages is also presented herein.
