Title: METHOD AND DEVICE FOR PRODUCING CHIP CARDS
Abstract:
Difficulties arise during the production of chip cards with integrated components, specially antennas, i.e. contactless chip cards, when recesses are to be made in the body of said cards so that the contact areas of the antenna remain accessible. According to the invention, a hobbing process involving a hobbing tool is interrupted when an electrical measurement indicates that the hobbing tool has touched a contact section of the antenna.
