Patent ID: 8313981

Claim:
A method for producing chip cards, comprising the steps: providing a foil substrate with a front side and a back side, with several communication contact layouts for contact-type communication of the chip cards to be produced with external communication devices on the front side and several flip chip contact layouts for connecting respectively at least one flip chip on the back side, and wherein the several flip chip contact layouts are electroconductively connected with respectively one of the several communication contact layouts; if the several flip chip contact layouts are not already equipped with flip chips, mounting flip chips onto the flip chip contact layouts; providing a reinforcement layer, wherein the reinforcement layer comprises a reinforcement foil; providing an intermediate foil and arranging the intermediate foil between the foil substrate and the reinforcement foil; bonding the foil substrate fitted with the at least one flip chip with the reinforcement foil and intermediate foil to form a layered material; and severing individual chip cards with chip-card end product dimensions from the layered material, wherein the intermediate foil comprises a material which is softer than the materials of the foil substrate and of the reinforcement foil, and wherein, during the bonding to form the layered material, the flip chips are embedded in the intermediate foil.
