Abstract: Device for selective electrodeposition of metal flat stock, on laddered or bandoliered component strips having at least one station filled with electrolyte through which the component strips are transported lengthwise. The device includes a longitudinal guide means for the component strips-the guide means is provided with a slot shaped chamber. The chamber, at its lower side is in open contact with a plating bath filled with electrolyte on a level lower than the electrolyte level in the plating bath. The guide means has apertures for introducing pressurized gas or air. The plating bath contains tubes with holes in such a position that during operation electrolyte recirculated through a transport pump can be jetted onto the portion of the metal or component strip which extends below the slot-shaped chamber of the guide means into the electrolyte.

Abstract: A method and apparatus for the continuous application of strip-, ribbon- or patch-shaped coatings of a noble metal to an electrically conductive tape by utilizing non-conductive belt means moving in concert with the tape as they simultaneously traverse an electrolitic solution. The non-conductive belt means shields the tape from the solution in those areas where a coating is not desired.

Abstract: A process and a device for selectively applying a metal coating, more particularly of a precious metal such as gold, to the metal parts of electrical components such as transistors, diodes and similar elements passed through an insulator means are provided for immersing the parts to be coated in a chemically active electrolyte and the parts not to be coated in a chemically inactive electrolyte and connecting the two electrolytes to the opposite polarities of the current source.
