Abstract
An apparatus and a method are disclosed for producing an electric terminal contact on a coated sheet, whose coating has at least one electric conductor path covered by an electrical insulation layer, in which apparatus and method a recess is produced extending through the insulation layer at least to the electrical conductor path and in this recess, an electrically conductive contact element is provided, one end of which is electrically connected to the conductor path and at the other end of which forms the electrical terminal contact. In order to increase the reproducibility, the proposal is made for the recess to be produced with the aid of a hollow needle, which is advanced in the direction toward the conductor path and which, as it is withdrawn from the recess, introduces an electrically conductive, viscous compound into this recess in order to produce the contact element.
