Electroplating and Activation using Conductive Fibres

      Disclosed is a method where conductive fibres can be used for
the following applications:

      Electrolytic cathodic metal-deposition Activation of metal
surfaces in electroless plating baths

Mode of operation
  o  By touching the surface the cathodic current is transferred from
      the fibres to the metallic surface of the part, or area of the
      part that has to be plated.
  o  Due to high overpotential on the surface of the fibres there is
      no, or less plating on the fibre surface and the current is
      transferred to the metallic surface of the part.
  o  Due to the movement of the part or either the fibres the total
      surface of the part will be connected.

To transfer the current the fibres must have the following
attributes:
  o  electrolytic conductivity
  o  mechanical strength
  o  high flexibility
  o  high overpotential

The following materials can be used:
  o  carbon fibres
  o  carbon coated fibres
  o  electric conductive fibres

The method described herein can be applied to:
  o  plating of insulated metal areas on an insulator
  o  selective contacting of metal areas on a insulator
  o  contact material for barrel plating
  o  activation of metal surfaces in electroless bath by applying a
      short cathodic current

It has the following advantages:
  o  no missing metallization in the area where usually a fixed
