A method of fabricating a microcircuit card provides better control of the spreading of a hardenable coating material during fabrication of the microcircuit card. The surface of a support is treated to define at least two areas with different surface states and both extending beyond a predetermined location of the microcircuit. The deposit of the material is delimited by the configuration of these areas. The treatment is preferably applied by means of a laser beam.

Method of fabricating a microcircuit card

A method of manufacturing a microcircuit board with a mechanical cut-out piece between the microcircuit and the board to limit stresses transmitted to the microcircuit. A blank of a network of conductors is created and the microcircuit is fixed in a container formed by shaping the blank, the microcircuit keeping the different parts of the network in position relative to each other and the module thus formed is installed in a cavity in the board by fixing the external connection areas onto the upper surface of the cavity.
