Abstract:
The invention relates to a dispersion for applying a metal layer to an electrically non-conductive substrate containing an organic binder component, a metal component with different metals and/or metal particle shapes, and a solvent component. The invention further relates to methods for producing said dispersion, methods for creating an optionally structured metal layer with the aid of the dispersion, the obtained substrate surfaces, and the use thereof.
Abstract:
The invention relates to a device for electroplating at least one electrically conductive substrate (8), or an electrically conductive structure situated on a non-conductive substrate (8). Said device comprises at least one bath, an anode and a cathode (2). The bath contains an electrolyte solution, which comprises at least one metal salt and from which metal ions are deposited on electrically conductive surfaces of the substrate, as the cathode is brought into contact with the surface of the substrate to be coated and said substrate is conveyed through the bath. The cathode comprises at least one strip (2) with at least one electrically conductive segment (12) and is guided around at least two rotating shafts (3). The invention also relates to a method for electroplating at least one substrate that is carried out in a device according to the invention. According to said method, to produce the coating, the strip lies on the substrate and circulates at a speed corresponding to the speed at which the substrate is conveyed through the bath. The invention further relates to the use of said device for electroplating electrically conductive structures situated on an electrically non-conductive support.

The invention relates to a method for producing structured, and/or the entire surface spanning, electrically conductive surfaces (3, 11) on an electrically nonconductive carrier 5 (1), wherein in a first step the surfaces (3) of a first level are applied to the carrier (1), in a second step the insulating layer (9) is applied at those positions, at which structured, and/or the entire surface spanning, electrically conductive surfaces (11) of a second level cross the structured, and/or the entire surface spanning, electrically conductive surfaces (3) of the first level, and no electrical contact is to occur between the structured, and/or the entire surface spanning, electrically conductive surfaces of the first level (3) and of the second level (11), in a third step the structured, and/or the entire surface spanning, electrically conductive surfaces (11) of the second level are applied according the first step, and the second and third steps are repeated, if necessary.
Abstract:
The invention relates to a device for electroplating at least one electrically conductive substrate or a structured or electrically conductive surface covering the whole area of a non-conductive substrate. Said device comprises at least one bath, an anode and a cathode. The bath contains an electrolyte solution, which comprises at least one metal salt and from which metal ions are deposited on electrically conductive surfaces of the substrate to form a metal layer, as the cathode is brought into contact with the surface of the substrate to be coated and said substrate is conveyed through the bath. The cathode comprises at least two discs (2, 4, 10) that are rotatably mounted on a respective shaft (1, 5, 14), said discs (2, 4, 10) intermeshing. The invention also relates to a method for electroplating at least one substrate, said method being carried out in a device according to the invention. The invention further relates to the use of said device for electroplating electrically conductive structures situated on an electrically non-conductive support.
