Detection of Multiple Failure-Modes in Electronics using Self-Organized MappingUltra-high reliability field applications including avionics, automobile,
military and defense require prolonged operation under extreme environments without any extended downtime.
Damage may be accrued in electronic systems because of thermo-mechanical environments, shock and vibration.
Structural health monitoring systems are needed to maintain high level of product uptime, while ensuring reliable
operation under extreme environments. Methods for fault mode classification can enable the non-destructive assessment
of the underlying failure modes prior to occurrence of system failure. Common damage detection procedures
currently used in electronic packages include detection of resistive opens, built in self test and use of auxiliary
devices such as fuses and canaries. Diagnostic detection of resistive opens provides little insight into the
pre-failure space of the device. The built in self test provides little or no insight into underlying reliability,
existing failure mechanisms and remaining useful life of the device. Fuses and canaries are methods for providing
advance warning mechanisms by requiring failure of the sacrificial device prior to failure of the system.
Fuses and canaries provide no insight into the failure progression prior to failure of the fuse or canary.
