Wet etching is done by using Transene Gold Etch 8111. Gold etchant 8111 is a cyanide free based etchant that provides strong definition with minimal undercutting. Gold etchant is potassium iodide and iodine based. You can get a good estimate of etch gold etch rates through other chemicals from ["Etch rates for micromachining processing"] and ["Etch rates for micromachining processing-Part II"]
