Electrical circuits, electronic modules for chip cards formed on electrical circuits, and methods of manufacturing such electrical circuits

摘要

The present invention relates to electrical circuits of the type of printed circuits, for example, for the manufacture of modules which are intended to be integrated into cards, such as chip cards. The module includes electrical contact pads-or connectors 3-that allow the chip to be connected to and communicate with the read/write system. The electrical contact pads are at least partially covered with a layer of rhodium alloy 13 to provide the white or near white color to the electrical contact pads. The invention also relates to a method of manufacturing such an electric circuit.
