Method of manufacturing an electronic device having a chip and/or an antenna, and a device obtained by implementing the method
First Claim
1. A method of manufacturing an electronic device having a chip and an interface comprising an antenna, said electronic device including at least one decorative sheet having a visible outside face, said method including the following steps:
- printing graphics on the visible outside face of the decorative sheet;
subsequently forming the antenna on a face of the decorative sheet which is opposite said visible outside face by screen-printing a conductive ink that has a metal particle content lying in the range approximately 60% to 95% in a polymer matrix and a solvent; and
partially drying the ink at a temperature lower than a predetermined optimum drying temperature.
