Device and method for producing an electrical connecting contact on a coated metal sheet

A method 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, the method comprising:

• producing a recess extending through the insulation layer at least to the electrical conductor path;
• providing an electrically conductive contact element in the recess, with one end of the electrically conductive contact element electrically connected to the conductor path and another end of the electrically conductive contact element forming the electrical terminal contact;
• and
• providing at least one hollow needle, which accommodates a viscous compound and has at least one sensor for detecting at least one measurement variable, which depends on a distance from the hollow needle to the electrical conductor path;
• wherein the recess is produced with the aid of the at least one hollow needle, which is advanced in a direction toward the conductor path as a result of measuring the measurement variable in order to limit an advancing depth of the hollow needle in a direction toward the sheet and, as the hollow needle is withdrawn from the recess, the hollow needle introduces the electrically conductive, viscous compound into the recess in order to produce the contact element.
