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).

Procédé permettant de tester le fonctionnement de cartes de circuits imprimés, qui consiste à appliquer directement sur au moins une face d'une carte de circuits imprimés (1) une couche souple (2) ne laissant initialement pas passer le courant de manière à établir le contact, ladite couche étant connectée de manière fonctionnelle à un conducteur de courant (3), puis à mettre ladite couche (2) sous tension. Un passage de courant est alors partiellement créé vers les sites de contact qui délimitent une piste conductrice (5) à tester. Le flux de courant dans la piste conductrice (5) est ensuite mesuré par l'intermédiaire du conducteur de courant (3).
