Abstract (en)

[origin: DE19940480A1] The invention relates to a conductor track supporting layer (1) for laminating inside a chip card comprising at least one conductor track (2), which is applied to the conductor track supporting layer (1) during a screen printing method and which is made of a screen printing paste, and comprising connecting areas (3) that are connected to the conductor track (2). According to the invention, the conductor track supporting layer has indentations (4a, 4b, 4c) which are located in the area of the connecting areas (3) and which are filled with the screen printing paste during the screen printing process. By using these inventive measures, it is possible to produce conductor track supporting layers provided with connecting areas of varying thicknesses. Conductor track supporting layers of this type enable the production of recesses in the chip cards after said conductor track supporting layers are laminated in chip cards. These recesses expose the connecting areas (3) for connection to electronic components, and the sensitive strip conductors (2) also located in the chip card are prevented from becoming damaged. The invention also relates to a chip card provided with the above-mentioned conductor track supporting layer and to a method for producing a chip card of this type.
