Definitions

  • the invention relates to a process for the metallization of capacitor foils made of plastic and a device for carrying out this process.
  • Metal-plastic capacitors are made of a thin plastic film on which a metal layer is vapor-deposited.
  • the metal layer is regularly about 0.05 ⁇ m thick. After the film has been processed into cylindrical coils or flat coils, a voltage is applied to the coils. In case of any defects of the plastic film thereby evaporate the thin assignments around the defect, the capacitor remains usable (so-called self-healing). However, this is only possible if the metal layer is very thin.
  • the metal layer is made thicker.
  • the obvious solution to make the vapor-deposited metal layer thicker fails because it would also form in the region of the defects and self-healing can no longer take place.
  • DE 760 157 C discloses an arrangement for burning out defects in the condenser foils.
  • the invention is therefore based on the object to provide a method for producing a Me ⁇ tall plastic film, wherein the metal layer can be applied relatively thick.
  • this object is achieved by burning out the vapor deposited first metal layer in the region of the defects of the plastic film and then alsgal ⁇ vanishing a second metal layer on the first metal layer.
  • the invention is therefore based on the fact that in a galvanizing a second metal layer - unlike a vapor deposition - the second metal layer will settle only in the region of the first metal layer in which the first metal layer is not burned out, so that in the Defects of the plastic film also the second metal layer will not form.
  • the second metal layer may consist of the same metal as the first metal layer, but the method proposed here also allows the second metal layer to consist of a different metal layer than the first (vapor-deposited) metal layer.
  • the burning out (vaporization) of the first metal layer in the region of the defects of the film can take place by guiding the films between a first roller whose surface has a first electrical voltage and a second roller whose surface has a second electrical voltage.
  • the film vaporized with a metal layer bears against the surface of the first roller with the metal layer and against the second roller with the insulating plastic film.
  • the metal layer leads the tension of the first roller into the area of the second roller, in the area of imperfections there is a flow of current which leads to an evaporation of the metal layer in the area of these defects ("burnout").

Abstract

L'invention concerne un procédé pour revêtir une feuille plastique servant à la fabrication d'un condensateur alliant métal et plastique. Selon l'invention, une première couche métallique mince est appliquée par dépôt en phase vapeur sur la feuille plastique, la première couche métallique appliquée par dépôt en phase vapeur dans la zone des défauts de la feuille plastique étant enlevée au feu, puis une deuxième couche métallique est appliquée par galvanisation sur la première couche métallique.
