Process for electroplating palladium |
摘要 |
The invention is a process for electroplating palladium in which at least part of the palladium in the electroplating bath is added as a palladium ammine hydroxide. Both the solid form of and solution form of palladium ammine hydroxide are useful in supplying palladium to the palladium electroplating bath. Both solution and crystals are chemically stable and can be stored for long periods of time. Further, use of the palladium ammine hydroxide compounds permit replenishment without accumulation of undesirable ions in the bath and also neutralizes hydrogen ions formed in the plating process.
