Abstract:
The invention concerns a method for connecting conductive pads (9) of a micromodule (2) to accessible connection areas (3a, 3b) of a support (1) of a portable object (100), comprising the following steps of: - providing or producing a body 1 of the portable object comprising a recess (11) for receiving the micromodule and connection areas in the recess, said recess opening at the surface of the body and being defined at the surface of the body by a first periphery (P1), - producing a micromodule comprising conductive pads (9) on a front face, defined by a second periphery P2 substantially corresponding to first periphery P1, and connection portions (10) folded towards a rear face of the micromodule opposite the front face, - inserting the module into the recess, said connection portions being brought into electrical connection with the respective connection areas (3a, 3b) thereof. The method is characterised in that said connection areas extend in said recess perpendicular to a direction of insertion of the micromodule into the recess. The invention also concerns the portable object obtained.
Abstract:
Method for making an electrical or electronic device with a supply or communication interface. The invention relates to a method for making an electrical or electronic device with a leadframe at the communication interface, comprising the following steps: - providing or producing a plurality of said electrical (2A) or electronic (4A) devices on a leadframe (1); - separating said device (2A, 4A) from the leadframe (1). The method differs in that it includes a step of forming a preliminary cut (5) in the leadframe about each device, said preliminary cut (5) being suitable (24) for enabling the manual separation of each device (2A, 4A). The invention also relates to a device thus obtained and to a leadframe coil comprising said devices.
Abstract:
This invention relates to a smart card (1) manufacturing method that makes it possible to reduce the thickness of the said smart card and directly obtain a final 3FF or 4FF format. The smart card manufacturing method comprises steps for depositing resin forming a first protective coat (11) over the electronic element assembly with a surface greater than the required smart card format and depositing a second protective coat with a format larger than the required card format on the first protective coat. The second protective coat is fixed to the first protective coat by curing the first protective coat, and then the assembly obtained in that way is cut to the required format.
Abstract:
The invention relates to a method for manufacturing an electronic device (13a, 13b), including a module (1, 15) attached in a recess of a carrier body, said module including a backing film (2) having a metal coating (3) on an upper surface side and on a lower surface side, an integrated-circuit chip (6) connected to the metal coating using electric connection wires (7, 8), the integrated-circuit chip being coated with a coating and mechanically protective material (9). The method is characterized in that it includes an anchoring step according to which a second anchoring material (11) is provided for bonding a portion (7p, 8p, 17p, 18p) of at least one of said electric wires and for anchoring said wire portion to the carrier body.
