A new CN-free silver plating process that can be utilized in barrel and rack applications has been in production use for more than a year. A discussion on the bath parameters, plating characteristics and the properties of the silver plate will be presented. Platers who are currently using this process have found it to be easy to operate and say it has many advantages over other alkaline CN-free silver plating processes. It offers brilliant white color, very stable chemistry, and a wide operating window. Some platers have even found advantages over CN-silver plating processes. By switching to this process, the plater can meet requirements of EPA's Common Sense Initiative by eliminating or reducing their cyanide use, which would lower the plater's hazardous waste.
