  • Patent number: 8277602
    Abstract: To ensure a uniform flow over the surface of a product W, an apparatus is provided for the wet chemical treatment of the product W that is disposed in the apparatus 100. This apparatus comprises at least one flow member 150 that includes respectively at least one paddle-like flow element 155, wherein at least one flow member 155 is disposed situated opposite the surface of the product W and is moveable substantially parallel to the surface of the product W.
    Type: Grant

  • Patent number: 7056424
    Abstract: In order to regenerate permanganate solutions being utilized for the etching and roughening of plastics surfaces electrolytic methods are known. Though relatively small quantaties of by-products are produced with these methods as compared to chemical regeneration methods, large quantaties of manganese dioxide are produced when printed circuit boards are treated. In order to avoid formation of manganese dioxide during the regeneration method a novel cathode 2 has been found which is provided with a porous, electrically nonconducting layer 7 on the cathode body 3. The layer 7 preferably consists of a plastics material being resistant to acid and/or alkali.
