... of nickel ions are sufficient to cause a rapid decomposition of the borohydride bath reported by Okinaka. Because of the effects of nickel, the use of an immersion gold coating of about 0.25 μm over a nickel substrate is often recommended prior to electroless gold deposition. Some electroless gold...
