The invention concerns a method for making an electronic device, such as a chip card, comprising at least an integrated circuit chip (200) housed in a card body (100) cavity (120). The chip (200) is connected, via strip conductors (112), to interface elements (110). The cavity (120) has sloping walls. The strip conductors (112) and the interface elements (110) form a pattern which results from three-dimensional electrically conducting printing. The pattern extends from the card support surface (100) along the cavity (120) sloping walls up to the base thereof. Said method enables to increase production rate and reduce production cost.

L'invention se rapporte à un procédé de fabrication d'un dispositif électronique, tel qu'une carte à puce, comprenant au moins une puce de circuit intégré (200), qui est logée dans une cavité (120) du corps de carte (100). La puce (200) est connectée, par l'intermédiaire de pistes conductrices (112), à des éléments d'interface (110). La cavité (120) présente des parois inclinées. Les pistes conductrices (112) et les éléments d'interface (110) forment un motif qui est obtenu par impression d'encre conductrice en trois dimensions. Le motif s'étend de la surface du support de carte (100), le long des parois inclinées de la cavité (120) jusque dans le fond de celle-ci. Ce procédé permet d'augmenter la cadence de fabrication des cartes à puce et de réduire leur prix de revient.
