ABSTRACT:
A process for testing circuit boards for serviceability is designed such that a flexible layer (2) that is initially impermeable to current is placed directly on at least one side of the circuit board (1), making contact, and it is dynamically connected to a current conductor (3), the layer (2) is then energized and then a current passage is partially created at the contact points that delimit the respective conductor path (5) that is to be tested, and then the flow of current in the conductor path (5) is measured using the current conductor (3).
