Abstract
A method and device for determining the existence of a leak in a package includes generating an AC high voltage with a DC high voltage offset in a circuit. A package is placed between an inspection electrode and a detection electrode, which are located within the circuit. The inspection electrode applies the AC high voltage with the DC high voltage offset to the package. Current flow through the package is then detected by the detection electrode. A detection board then processes the current flow and sends the processed signal to a programmable logic controller which determines if a leak is present in the package. If a leak is present, a signal is sent to a display to notify a user.
