ARGUNA® ET-S Fine Silver Electrolyte

ARGUNA® ET-S Fine Silver Electrolyte

High-speed electrolyte for reel-to-reel plating

The ARGUNA® ET-S silver electrolyte is an alkaline-cyanide process specifically developed for use in high-speed equipment for reel-to-reel silver plating (using flow or spray technologies). The process deposits smooth and fine-grained, semi-bright coatings which are particularly suitable for semiconductor technology.

Current density and plating speed depend on the electrolyte agitation at the parts, i.e. on the equipment used. High electrolyte flow allow very high current densities.
