Abstract:
1. A shunt defect detection device, comprising: a. a device under test (DUT), wherein said DUT is fixedly held by a thermally isolating mount; b. a power source, wherein said power source is disposed to provide a directional bias condition to said DUT; c. a probe, wherein said probe is disposed to provide a localized power to said DUT from said power source; d. an emission detector, wherein said emission detector is disposed to measure a temporal emission from said DUT when in said directional bias condition, wherein said measured temporal emission is output as temporal data from said emission detector; and e. a suitably programmed computer, wherein said suitably programmed computer uses said temporal data from said emission detector to determine a heating rate of said DUT and disposed to estimate an overheat risk level of said DUT, wherein an output from said computer designates said DUT a pass status, an uncertain status, a fail status or a process to bin status according to said overheat risk level.
