<p>A gold plating bath having potassium aurous cyanide and thiourea complexing agent dissolved in water and adjusted to an acidity of pH 3 or lower can be used as either electro-plating or electroless plating bath. Bright gold electro-plating is possible when a brightener is added to the bath. Electroless plating is possible when a reducing agent, typically sodium hypophosphite is added to the bath.</p> |
