Abstract
The invention concerns an electronic module for a small portable object such as a card or a key incorporating an integrated circuit, and a method of mass producing such modules. The electronic module according to the invention includes a substrate (24) of insulating material, an integrated circuit chip (8) having at least two connector lugs (10) and which is fixed at least indirectly to the substrate, a coil (12) also fixed on the substrate and serving to provide an inductive coupling between the module and an apparatus with which the portable object is designed to cooperate, and electrical connections (18,20) respectively between the chip's connector lugs and the terminals (17) of the coil. In this module, the coil is an annular coil which surrounds a space in which the chip and the electrical connections are fully housed in a hardened, electrically insulating adhesive material (28) filling the space. Such a module may be mass produced at low cost and, when it is then incorporated in a card, the coil effectively protects the chip and the electrical connections against any constraints to which the card is submitted.
