Abstract
Aspects of the present disclosure are directed toward detection of leakage from an enclosed component using an apparatus. The apparatus includes a printed circuit board (PCB) including a first conductive trace, a second conductive trace, and sets of terminals electrically connected to the first and second conductive traces configured and arranged to indicate changes in impedance caused by leaked liquid. The respective portions of the first and second conductive traces are interleaved, and configured and arranged to suspend flow of the leaked liquid from an enclosed component, thereby causing a change in impedance between at least one of the sets of terminals.
