Abstract

L'invention concerne un circuit imprimé (1) multi-couches comprenant un circuit de contrôle (1a) comportant n vias (3) connectés en série entre une première (4a) et une deuxième borne électrique (4b) de façon qu'un courant électrique appliqué traverse au moins partiellement chacun des n vias (3). Le circuit de contrôle (1a) comprend des portions de piste (20a à 23a ; 20b à 23b) dans chacune des couches (10 à 13), chacun des n vias (3) reliant une portion de piste d'une couche avec une portion de piste d'une autre couche. Le circuit de contrôle (1a) comprend des moyens de mesure (6) d'une différence de potentiel à ses bornes, des moyens de mémorisation d'une valeur seuil et des moyens de comparaison de la différence de potentiel avec la valeur seuil de façon à valider le circuit imprimé (1) lorsque la différence de potentiel est inférieure à la valeur seuil.
