Contact George Milard, I believe Uyemura has an immersion gold over copper chemistry.

Best regards

  Subject: [TN] Copper Plating on Gold (Galvanic)


  Hi folks,

  Anybody know what the chemical reaction is to plate Copper onto Gold,
  through the electroless processes (or Galvanic), not electrolytic?

  To explain further, we know Silver and Nickel can plate on copper through an
  Electroless or Immersion process.  Can that process be reversed where the
  Copper plates on Silver or Nickel?  Or, can a chemistry be developed where
  the Copper plates on a more noble metal of Gold?

  Thanks,

  Glenn
