    摘要: The chips for chip cards are customarily provided on a film strip which consists of a synthetic foil and a conductor track pattern and are connected to the conductor track pattern by way of bonding wires. Automatic mounting is made possible by the use of a film strip with periodically arranged conductor track patterns. For chips which can be driven via contacts as well as in a contactless manner, using a coil, conductor tracks are effectively provided on both sides of the synthetic foil forming the film strip. However, the film strip then becomes very inflexible so that it cannot be suitably handled by conventional automatic apparatus. The invention proposes to provide the metal foils wherefrom the conductor tracks are cut out with additional interruptions which reduce the cross-section of the metal foils at short intervals in the direction perpendicular to the longitudinal direction of the film. The film strip thus becomes more flexible so that it can be handled by conventional automatic apparatus.
