Abstract: An apparatus (10) and method for inspecting articles incorporating positive temperature coefficient resistors. The inspection apparatus includes a computing device (20), a power source (18), a housing (12), a support (14A), and a thermal imager (16), each mounted within an interior volume (24) of the housing (12). The inspection method includes receiving a first thermal image of the unpowered article mounted within the support (14A) and receiving a second thermal image of the powered article after an optimized time delay. The method further includes outputting a health indication of the positive temperature coefficient resistors based on a comparison of the first thermal image and the second thermal image.
