    Most conventional pure gold electroplating processes used in the electronics industry are cyanide based. Due to the toxicity of the free cyanide formed during electrolysis, as well as cyanide's incompatibility with positive photoresists, sulfite-based gold processes have been the traditional alternative for wafer applications. However, traditional sulfite-based processes have suffered from ...
