摘要:
An IC card comprises a module with an electric circuit and two panels adhered to each other to cover the module between them. The two panels are adhered with an adhesive with a sufficient adhesion strength and seals the module with no path of air to the outside of the IC card. Airtight sealing of the IC card in realized in various ways. For example, a groove having a varying width is provided in one of the panels for applying an adhesive, while a groove engaging to the groove is provided in the other of the panels. When the two panels are adhered to each other, gas channels may be formed in the groove at portions with narrower widths, while an adhesive in the groove at portions with wider widths fills the gas channels due to viscosity. In another way, a protrusion provided in one of the panels has an edge opposite to a groove provided in the other of the panels. Thus, the groove is kept air-tight. In a different way, an adhesive having a high viscosity at curing temperature is used. In a still different way, all the space inside the IC card is filled, or a sufficient amount of an adhesive is filled in a space between the two panels around a peripheral thereof. In a further way, the panels are adhered in a thermostat. In a still further way, the panels are adhered with melting at a peripheral thereof.

An IC card includes a substrate having a metal fiber resin material layer made of a mixture of a resin and metal fibers and a conductive pattern. The conductive pattern and the metal fiber resin material layer are electrically insulated from each other by a resist film. Heat radiation and mechanical strength of the IC card are enhanced.

A memory card comprises a plastic outer package which houses a semiconductor device and electrical connector. The outer package comprises a plurality of package sections which are stacked atop one another and bonded together along connecting surfaces formed on the outer peripheries of the package sections. The connecting surface of one package section of each pair of adjoining package sections has a projecting engaging portion formed thereon, and the connecting surface of the other package section of the pair of adjoining package sections has a recessed engaging portion formed therein which engages with the projecting engaging portion of the adjoining package section.
摘要:
A mechanism for connecting an IC card and an external device to each other, having: a plurality of electrode terminals formed on a package of the IC card incorporating a semiconductor device and used to connect the semiconductor device to the external device; at least one engagement recess and/or engagement projection formed on the package of the IC card; and a connector provided in the external device. This connector is provided with an insertion hole, a plurality of electrode-contacting pieces disposed in the insertion hole and capable of contacting the plurality of electrode terminals of the IC card when the IC card is inserted into the connector, and at least one engagement projection and/or engagement recess formed inside the insertion hole and capable of engaging the engagement recess and/or engagement projection formed on the package to enable a particular type of the IC card to be inserted into the connector.
摘要:
A semiconductor device card and a method of manufacturing the card. A frame includes an integral spacer which fills a dead space on a circuit board to eliminate the need for positioning a separate spacer in the dead space on the circuit board and fixing the spacer in place with a bonding sheet or the like. In a semiconductor device card in which a spacer for filling a dead space on the circuit board is bonded to a corresponding panel, a recess is formed on the surface of the spacer bonded to the obverse or reverse panel to reduce undulations occurring in the panel surface.
摘要:
An IC card has a card body with a plurality of slits extending through the thickness card body and a pair of metallic panels secured to the card body. The metallic panels have engaging portions which extend into the slits when the metallic panels are secured to the card body so that the engaging portions of both panels engage each other within respective slits to fasten both metallic panels to the card body. The electrical potentials of both metallic panels are equalized through these engaging portions.
