Abstract
The method for producing a microcircuit card including a film having a very low level of shrinkage between two overlay layers, carrying at least one electronic component and an assembly of layers in which a cavity is formed containing the film and the electronic component, involves: forming the assembly to include a central layermade from a material having a very low level of shrinkage between two layers of a plastic material having a substantially higher level of shrinkage, for example PVC, forming, through the assembly, a cavity of which the surface area advantageously equals between 30% and 90% of the surface area of the outer faces of the microcircuit card that is to be produced, embedding the film and the electronic component in a resin so as to occupy the space in the cavity and laminating the two overlay layers.
