ABSTRACT:
To provide for uniform distribution of contact element bodies which are placed in a drum immersed in a galvanic bath and to provide contact to the metallic coating on components, the metallic coating of which is to be reinforced by galvanic deposition, the contact elements comprise tiny, especially cylindrical cores made of a material having approximately the same order of magnitude of specific gravity as the components, for example being made of a similar material, of glass, plastic, or the like, and coated with a metallic coating on the outside, essentially entirely covering the cores. The coating may be nickel or copper, and for use with tiny capacitors, lead-through elements, and the like, a preferred size of about the same length as diameter of the coated e.g. cylindrical cores is suitable, for example about 3 mm length and diameter. These elements can be made by multiple dry extrusion, with the edges rounded off before being coated.
