Abstract :
Leakage current through a printed circuit board epoxy has a strong Arrhenius dependence on temperature. Fire and smoke occurrences can be prevented by monitoring the leakage current between a ground plane and an adjacent test plane and shutting off power if the leakage current rises above a predetermined critical value.
