Abstract

L'invention propose un élément de circuit non réciproque qui améliore la stabilité et la fiabilité d'une connexion par soudure entre une électrode de borne d'une carte de circuit imprimé et une électrode agencée sur de la ferrite. L'élément de circuit non réciproque est pourvu d'un aimant permanent ; de la ferrite à laquelle un champ magnétique continu est appliqué par l'aimant permanent ; des première et seconde électrodes centrales agencées sur la ferrite ; et une carte de circuit imprimé(20). Une électrode de connexion agencée sur la ferrite est électriquement connectée par l'intermédiaire d'une soudure à des électrodes de borne (25a, 25b, 25c) formées sur la carte de circuit imprimé (20). Sur les électrodes de borne (25a, 25b), des sections empêchant un écoulement de soudure (27a, 27b) sont formées par irradiation au laser. La soudure appliquée sur des sections d'extension (25a', 25b') des électrodes de borne (25a, 25b) est bloquée par les sections de prévention (27a, 27b) lorsque la soudure est fondue, et lesdites sections empêchent la soudure de s'écouler hors du côté de corps principal des électrodes de borne (25a, 25b).
