Abstract: An electronic package includes an integrated circuit chip mounted to a support plate and encapsulated by an encapsulating body. The package includes at least one weakening deep perforation. The perforation is formed in either the support plate or the encapsulating body, and functions to reduce a resistance of the package to bending stresses perpendicular to the support plate.

Abstract: A method electrically connects a semiconductor chip, having contact pads, with an interconnection support, having a substrate and reception pads. The method comprises a step of growing a first metal layer on the contact pads of the chip and a step of growing a second metal layer on the reception pads of the interconnection support, by metal electrodeposition, until the first and the second metal layers meet and form an electrical contact linking the contact pads of the chip and the reception pads of the interconnection support. The method can be applied to the manufacture of electronic cards and electronic modules.

Abstract: An electronic micromodule, particularly for smart card, comprises an electrically insulating substrate, at least one conductive sheet in an electrically conductive material, which rear face is attached to a front face of the substrate, and a semi-conductor chip. The substrate comprises an opening forming a window of access to the rear face of the conductive sheet, the chip is arranged within the opening and is fixed onto the rear face of the conductive sheet, and at least one contact of the chip is electrically connected to the rear face of the conductive sheet by means of an electrically conductive connecting material. The electronic micromodule may embody chip cards, electronic badges and electronic tags.

Abstract: A micromodule is used as a surface-mounted package on a substrate of interconnections. In one embodiment of the invention, barriers to the expansion of solder are formed between contact zones of the micromodule and corresponding contact pads of the substrate. A mechanical stopping device is planned to keep the thickness of the interface of solder. In another embodiment of the invention, contact zones are extended by tongues. A cambering operation enables the formation of the surface-mounting pins.

Abstract: A method for the manufacture of a micromodule with surface flush connector, the metallic regions of the connector being formed on a support grid, comprises the formation of protection barriers between the regions of the connector so as to form a closed contour demarcating a molding zone around the chip, outside a standardized space reserved for the physical connections between the connector of the micromodule and an external system, to make a molding of thermohardening or thermoplastic material around the chip in this demarcated molding zone.

Abstract: A chip card system provided with an offset portable electronic circuit includes a module that integrates one or more electronic components, a reader 4 of this module, an intermediate means 3 directly linked with the reader 4 and a conveyance means 2 to provide for the transmission of information between the module 1 and the intermediate means 3, and vice versa. The intermediate means is a chip card that enables access to standard readers. The module can be used to set up a complex application without any problem as regards available surface areas. Moreover, the reliability obtained is that of the mounting of electronic components. It is far greater than that obtained in the technology of mounting a chip in a chip card.

Abstract: A portable and connectable chip-based electronic system has one or more chips integrated into a package. The electronic component obtained is mounted, in a first embodiment, on the upper surface of metal contacts. A lower surface has metal contacts that constitute the connector of the system. Each of the metal contacts of the upper face is connected to and faces a metal contact of the lower surface, and vice versa. In a second embodiment, the electronic component is surface mounted on an upper surface of metal contacts, the lower surface of these contacts forming the connector. A system such as this is designed to be inserted into a reader which will get connected to the connector. Such a system may have other electronic components that are mutually interconnected and interconnected with the electronic component.

Abstract: The disclosure concerns the encapsulation of integrated circuit chips, notably with a view to their being incorporated in a chip card. The encapsulation method comprises the formation of a pre-punched metallic conductive grid, the formation of a strip of pre-perforated plastic material, the transfer of a strip to the grid, the positioning of an integrated circuit chip in a perforation of the strip, and the formation of electrical connections between the chip and zones of the grid located in perforations of the strip. The perforations of the strip and the punched slots of the grid are arranged so that the strip covers and blocks all the interstices between conductors of the grid in the useful region corresponding to a module to be made. When a protecting resin is laid, it is confined and does not leak through the interstices of the grid. A plastic or metal ring defines the heightwise dimension of the micromodule.

Abstract: A housing designed to contain a logic circuit (15) comprising two shells (11a, 11b) each including a welding area (17a, 17b) having an appropriate geometry permitting ultrasonic welding, such that when both shells are assembled before a welding phase, they are shifted along a vertical axis (20). The supporting plate (13) comprises a mounting ear (23) while the shells comprise a receptacle (33a, 33b). During the welding phase, there is no concomitant contact between any of the upper face (26) and lower face (27) of the ear (23) and the corresponding bearing faces (34a, 34b) of the receptacles, owing to a shift (21). The shift is reduced and the concomitant contact takes place between the bearing faces (34a, 34b) of the receptacles and each of the upper and lower faces (26, 27) of the ear (23) only when the welding phase is completed.

Abstract: To encapsulate integrated circuits mounted on continuous dielectrical strips (surface-mounted circuits) it is proposed to transfer mold a thermosetting resin around circuits carried by the strip, the resin being injected outside the parting plane of the mold, contrary to the usual practice in this field. The protection of the circuits is improved while, at the same time, the ability to test the strip is preserved.
