Abstract:
1. A method of manufacturing electronic cards, each card including at least a first electronic unit at least partially arranged in a window in a solid layer of the card, and a second electronic unit electrically connected to the first electronic unit, wherein the method includes the following steps in series: (A) forming an electronic device, or an electronic assembly, by making an electrical connection at least between a first electronic unit and a second electronic unit; (B) providing a first solid layer having at least one window, wherein the at least one window is provided to at least partially receive the first electronic unit, and placing the first electronic unit of the electronic device, or the electronic assembly, in the at least one window; (C) providing a first protective film formed of several parts having respective profiles that, when assembled, define a first aperture into which the electrical connection passes, wherein the first aperture has smaller dimensions than those of the first electronic unit, or providing a second protective film formed of a single part having at least one slit starting from a second aperture made in the single part, wherein the dimensions of the second aperture are smaller than those of the first electronic unit, and placing the first protective film, or the second protective film, so as to cover the first solid layer in a zone peripheral to the at least one window and at least a lateral surface of the first electronic unit, to close any slit between the lateral wall of the at least one window and the first electronic unit, or to cover the first solid layer in the zone peripheral to the at least one window and an outer edge of a rear face of the first electronic unit to close any slit between the lateral wall of the at least one window and the first electronic unit; and (D) at least on the protective film, providing a filler material and forming a card by the filler material that is at least partially in a non solid phase, wherein the filler material at least partially covers the electrical connection of the electronic device or the electronic assembly.
