Abstract

L'INVENTION CONCERNE UN SUBSTRAT POUR CIRCUIT IMPRIME POSSEDANT DES ELEMENTS RESISTANTS FORMES A PARTIR D'UN REVETEMENT RESISTANT D'ALLIAGE ETAIN-NICKEL. LE REVETEMENT RESISTANT CONTIENT DE 50 A 85, EN POIDS, DE NICKEL ET EST DEPOSE ENTRE UN SUBSTRAT ISOLANT ET UNE COUCHE DE MATERIAU TRES CONDUCTEUR PAR ELECTROPLACAGE OU PLACAGE CHIMIQUE. SON EPAISSEUR EST COMPRISE ENTRE 70 ET 2000A ET SA RESISTANCE CARREE EST DE 20 A 450OHMS PAR CARRE. LE REVETEMENT RESISTANT D'ALLIAGE ETAIN-NICKEL SELON L'INVENTION POSSEDE UNE BONNE UNIFORMITE ET UNE BONNE STABILITE AUSSI BIEN MICROSCOPIQUE QUE MACROSCOPIQUE, ET ELLE PRESENTE UNE BONNE SELECTIVITE VIS-A-VIS DES SOLUTIONS DE DECAPAGE DE LA COUCHE DE MATERIAU TRES RESISTANT.
