Abstract:
The invention concerns a method for producing a printed circuit for a chip card module. This method involves producing two layers of electrically conductive material insulated from each other by a layer of insulating material, connection holes extending through the layer of insulating material and blocked by one of the layers of electrically conductive material, an area free of conductive material being provided in the other layer of electrically conductive material around the connection holes. The invention also concerns a printed circuit for a chip card produced using this method and a chip card module comprising such a printed circuit.

Abstract:
L'invention concerne un procédé de fabrication d'un circuit imprimé pour module de carte à puce. Ce procédé consiste à réaliser deux couches de matériau électriquement conducteur isolées l'une de l'autre par une couche de matériau isolant, des trous de connexion s 'étendant à travers la couche de matériau isolant et obturés par l'une des couches de matériau électriquement conducteur, une zone dépourvue de matériau conducteur étant ménagée dans l'autre couche de matériau électriquement conducteur autour des trous de connexion. L'invention concerne également un circuit imprimé pour carte à puce fabriqué avec ce procédé et un module de carte à puce comportant un tel circuit imprimé.
Abstract:
A printed circuit board for carrying high frequency signals. Conducting structures of the printed circuit board are shaped within breakout regions to limit impedance discontinuities in the signal paths between vias and conductive traces within the printed circuit board. Values of parameters of traces or anti-pads, for example, may be adjusted to provide a desired impedance. The specific values selected as part of designing a printed circuit board may match the impedance of the breakout region to that of the via. The parameters for which values are selected may include the trace width, thickness, spacing, length over an anti-pad or angle of exit from the breakout region.
