Electrolytic stripping method |
| abstract |
The present invention provides an electrolytic stripping method comprising electrolytically stripping: a copper plating film exposed from a silver plating film that partially covers a copper plating film formed on the entire surface of a member; and leaking silver formed on an exposed portion of the copper plating film and having a smaller thickness than the silver plating film, using the copper plating film as an anode, wherein the electrolytic stripping is carried out using a cyan compound-free electrolytic copper-stripping liquid, and the electrolytic stripping liquid comprises a compound capable of forming, with silver, a complex ion that is more easily dissociated than a complex ion of silver and cyan; and wherein silver and copper are deposited on a cathode which is used as a counter electrode to the anode and which is made of a metal that is chemically stable against the electrolytic stripping liquid. |
