Electrolyte is the conducting medium for the etching current. It carries the necessary metallic salts to etch the metal, and to develop the black residue for dark, contrasting marks. Necessary inhibitors, depolarizers, surfactants, and stencil cleaning media are also carried by the electrolyte. In addition, the electrolyte also serves as a coolant, and controls depth of mark through electrochemical action.
Choosing the proper electrolyte and cleaner is necessary to obtain a clear, sharp, contrasting mark. Lectroetch has developed electrolytes for various conductive metals, alloys, and plating. The chart will serve as a guide for most applications. Parts made of other materials should be sent to Lectroetch for electrolyte evaluation.
