The invention concerns a method for making an electronic device, such as a smart card, comprising at least a microcircuit (44) embedded in a carrier medium (40) and comprising exit hubs (46, 48) connected to interface elements consisting of a terminal block (50, 52) and/or an antenna, characterised in that the connections (54) between the exit hubs (46, 48) and the interface elements are produced by depositing, by means of a syringe, a conductive substance with low viscosity which remains ductile after it has been applied. Advantageously, a polymer resin charged with conductive or intrinsically conductive particles is used.
L'invention a pour objet un procédé de fabrication d'un dispositif électronique, tel qu'une carte à puce, comprenant au moins un microcircuit (44) qui est noyé dans une carte support (40) et qui comporte des plots de sortie (46, 48) reliés à des éléments d'interface constitués par un bornier (50, 52) et/ou une antenne, caractérisé en ce que l'on réalise les connexions (54) entre les plots de sortie (46, 48) et les éléments d'interface par dépôt, au moyen d'une seringue ou analogue, d'une substance conductrice à faible viscosité qui reste souple après son application. Avantageusement, on utilise une résine polymère chargée de particules conductrices ou intrinséquement conductrices.
