Definitions

  • This invention relates to a gold electroplating bath and more particularly to a gold electroplating bath which includes an organic additive.
  • the invention also relates to a process for the electrodeposition of gold using the bath.
  • Transition metal salts such as cobalt, nickel and iron salts
  • Gold electroplating baths which include these compounds have been found to give gold coatings of greatly improved wear resistance. For this reason, cobalt and nickel-containing acid gold electrolytes are widely used in the electronics industry.
  • cobalt and nickel brightened plating baths have been found to be lacking, because the maximum current density at which hard deposits can be obtained is relatively low.
  • Attempts have been made to overcome this disadvantage by using higher concentrations of gold (typically 15 g/1 instead of 8 g/1), but this substantially increases the cost of the process and the improvement obtained is only slight.
  • the coated plaques were tested for wear resistance using hemispherically ended brass probes (5 mm diameter) which had been similar plated.
  • the probe was loaded to 150 gf and moved in a reciprocating manner across the plaque surface at a linear velocity not exceeding 2.5 mm/sec over a path length of between 7 and 10 mm.
