| titleOfInvention | Displacement gold plating solution |
| abstract | The present invention provides a non-cyanide displacement gold plating solution with which even an electroless nickel-boron plated or electrolytic nickel plated substrate can be subjected to displacement gold plating with good adhesion properties and high solderability. The displacement gold plating solution in accordance with the present invention contains 0.01 to 1.0 g/L (expressed in terms of gold concentration) of sodium gold sulfite or ethylene diamine complex of sodium gold sulfite, 10 to 100 g/L of sulfite, 5 to 50 g/L of organic carboxylic acid or salt thereof, and 5 to 50 g/L of ethylene diamine tetraacetic acid or salt thereof, and has a pH value in the weak acid range of 4.5 to 6. |
