| 摘要 |
The invention concerns a process for the deposition of a silver-tin alloy from an acidic, cyanide-free electrolyte, containing silver ions, tin ions as well as a complexing agent. In order to provide a process which, despite the great differential of potential between silver and tin, makes it possible to simultaneously precipitate both metals to form well-adhering layers which, in addition, have a smooth, matte to silky surface and which are easily soldered, the invention involves the use of, as a further component an aromatic compound with an aldehyde group added to the electrolyte.
