Neutral high-speed electrolyte for selective gold-plating
The process is also well suited for chrome-nickel alloys, molybdenum steels and low activity nickel alloys. Excellent as a strike solution, prior to heavy deposit gold plating. A neutral electrolyte with high current efficiency producing matt yellow, pure gold deposits. The deposit has excellent bonding and soldering properties making it ideal for printed circuit and semiconductor applications. A pure gold strike bath which is intended for depositing thin pure gold layers 0. This provides an adherent layer to substrates or intermediate layers but also protects the main gold electrolyte from contamination. A weakly acid fine gold bath for rack and barrel applications.
Hard Gold Electrolytes
The neutral fine gold electrolyte was specifically developed for use in high-speed equipment for selective goldplating spray and flow lines, jet and spot plating. Maximum applicable current density and therefore plating speed as well essentially depend on the electrolyte agitation at the parts flow velocity , i. A high flow velocity allows a high plating speed. The layers exhibit outstanding bondability and excellent temperature resistance.

It is preferably used for chromium-nickel steels, molybdenum steels and nickel based alloys difficult to activate. Due to its strong activation effect, the electrolyte can be often successfully used as well for other passive materials difficult to plate. The gold electrolyte is suitable for both strike gold layers and thick coatings in the decorative field. The coatings are ductile, low in pores and protect against corrosion. The alloy electrolyte can be used for rack and barrel operation as well as in reel-to-reel plating e. Catalog excerpts. Open the catalog to page 2.
