METHOD FOR DEPOSITING A BRONZE ALLOY ON A PRINTED CIRCUIT AND PRINTED CIRCUIT OBTAINED BY SAID METHOD

Disclosed is a method for depositing a bronze alloy on a printed circuit (5). Said method comprises an operation of electrolytically depositing at least one layer of bronze (12) on a copper sheet (10). The bronze layer (12) comprises, after deposition, 45-65% by weight of copper, 35-45% by weight of...

Zusammenfassung:	Disclosed is a method for depositing a bronze alloy on a printed circuit (5). Said method comprises an operation of electrolytically depositing at least one layer of bronze (12) on a copper sheet (10). The bronze layer (12) comprises, after deposition, 45-65% by weight of copper, 35-45% by weight of tin and 2-11% by weight of zinc. Also disclosed is a printed circuit (5) obtained by this method. Procédé de dépôt d'un alliage de bronze sur un circuit imprimé (5). Ce procédé comprend une opération de dépôt électrolytique d'au moins une couche de bronze (12) sur un feuillet de cuivre (10). La couche de bronze (12) comprend après dépôt 45-65% en poids de cuivre, 30 à 45% en poids d'étain et 2 à 11 % en poids de zinc. Circuit imprimé (5) obtenu par ce procédé.
