Abstract

PROCEDE DE FABRICATION DE CIRCUITS IMPRIMES SUR UN SUBSTRAT ISOLANT. ON DEPOSE SUR LE SUBSTRAT UNE COUCHE SUPPORT DE VERNIS ELECTRIQUEMENT CONDUCTEUR, ON CONSTITUE SUR LE VERNIS UN MASQUE ADHERENT PRESENTANT UNE DECOUPE D'ACCES AU VERNIS SUIVANT LE TRACE DU CIRCUIT IMPRIME A REALISER, ON DEPOSE ELECTROLYTIQUEMENT UNE COUCHE DE CUIVRE 15 SUR LES PARTIES ACCESSIBLES DU VERNIS 11, ET ON DETRUIT PAR SOLVANT LE VERNIS SUPPORT 11 DANS TOUTES LES ZONES OU IL N'EST PAS PROTEGE PAR LE DEPOT DE CUIVRE, EN MEME TEMPS QUE LE MASQUE 12 QU'IL PORTE. APPLICATIONS COURANTES.
