Definitions

  • the invention relates to a method according to the preamble of claim 1.
  • anode metal fillers e.g. B. of copper
  • acidic baths e.g. B. copper alloyed with phosphorus
  • auxiliary anodes in the form of titanium baskets which are filled with the appropriate metal fillers, are often used for the electroplating of printing cylinders, printed circuit boards or other electronic device parts. It is important that these auxiliary anodes have the same filling over their entire area, so that the same possible deposition weight and the same deposition area are ensured during the whole operation, which are of crucial importance for exact support layers. These requirements are not met with the granules made of electrolytic copper scrap or sections of copper wires known in practice.
  • the object of the invention is to provide a method for producing spherical fillers for anode containers of the aforementioned type to be used in electroplating baths, which enables the manufacture of such fillers with high throughput and low cost.
  • Claim 2 specifies a method for producing an anode container filled with appropriately produced packing elements.
  • the solution according to the invention makes it possible to produce spherical anode bodies on an industrial scale and quickly in a quasi-continuous process.
  • the diameter of the packing balls is advantageously designed so that the balls roll individually through the loading opening of the anode container - and their diameter is somewhat smaller than the depth, but greater than half the depth of the anode container. If the balls are so large that only a single ball passes through the loading opening, there can be no blockages. The balls in the specified sizes also only form a stack layer. Optimal results are achieved if the balls of the filling of an anode container are the same size.
  • the wire to be formed into balls can be produced in the usual way by rolling, casting or pressing. Depending on the intended use, it will consist of pure or alloyed metal.
  • the wire diameter can be determined on a trial basis.
  • the drawing shows part of an anode container in section with the packing elements according to the invention.
  • Packing balls 3 are filled in an anode basket 1 made of a titanium wire mesh 2. Since the diameter d of the balls is slightly smaller than the depth f of the basket, the balls are stacked in one layer. Even if these balls are slightly offset or shifted, the contact surface is always the same due to the evenly rounded surface of the balls. Due to the spherical shape, the packing elements will always be arranged without gaps and without blocking, even when refilling, and thus enable a uniform filling level.
