  • Patent number: 4447298
    Abstract: Anode bodies for a galvanic plating bath, e.g. for electrodeposition of copper, are spheres which can be received in an anode holder in the bath and have advantages over irregular and other anode shapes deriving from the fact that the metal is solubilized uniformly substantially over the entire surface area of the anode bodies and a uniform reproducible contact is made between them. The invention also comprehends a method of making such bodies by pressing cylindrical blanks, e.g. wire sections, to spherical shape, and a method of operating an electroplating bath which involves the use of such anode bodies.
