Electrical circuit with contact track layer especially for chip card

摘要

The circuit incorporates a supporting layer (5), a contact track layer (4) with mutually insulated electrically conductive areas, and an electrical component (9) with contacts (14,15) for these areas. A recess (3) is formed through the supporting layer and into the body (2) of the card. At least one of the contacts is located in the vicinity of a boundary wall (17,18) of the recess, into which the contact track layer protrudes. At least one conductive area (6) of this layer is arranged in a region between the contact and the wall.
