The variation between different product lots is reduced for plating growth dimensions of plated films to serve as external electrodes. The correlation is grasped in advance among the surface resistance value of a ceramic body, the applying charge amount for electrolytic plating, an actual plating growth dimension obtained when the ceramic body with the surface resistance value is subjected to plating with the foregoing applying charge amount. The surface resistance value is measured for the ceramic body on which plated films to serve as external electrodes are to be formed by applying electrolytic plating, and the applying charge amount required for plating is determined by applying the surface resistance value and a designed value for an intended plating growth dimension to the correlation mentioned above. Thereafter, in order to form the plated films, the ceramic body is subjected to electrolytic plating, with the applying charge amount determined.

A barrel plating or high-speed rotary plating method for electronic components, and a neutral tin plating solution used therein. A plating solution that includes (A) stannous ions, (B) an acid or a salt, (C) a complexing agent, and (D) a diamine that has a polyoxyalkylene chain, and that has a pH in a range between 4 and 8 is used. The use of this neutral tin plating solution prevents the electronic components from coupling together during the barrel plating, enabling an improvement in manufacturability in barrel plating.

Methods for providing laminated coatings on metal articles using electroplating methods such as barrel plating, vibratory plating, rocker plating or other non-rack methods that involve movement of articles to be plated in a containment apparatus, as well as articles made from such processes. Embodiments of such processes involve mass-transfer modulation to provide compositionally modulated coatings.
