Achieving a Finer Grain Structure Using the Indium Sulfamate Plating Bath

From Indium Corporation
 

 

The indium sulfamate plating bath is a common method of depositing pure indium onto conductive metallic surfaces. A relatively common misconception about the bath is that the deposit will have a smooth or mirror-like finish, however a typical bath produces a frosted or matte-like finish.
