  • Patent number: 5313364
    Abstract: An IC card arranged so that a connector cannot come off a frame during an assembly process in which the connector and a circuit board are accommodated in the frame and panels are thereafter attached to obverse and reverse surfaces of the frame. Projections on sides of the connector and resilient engaging/fixing hooks with oblique surfaces on the frame are engaged. As the connector is forced into the frame, the projections of the connector are brought into engagement with and temporarily deflect the engaging/fixing hooks of the frame. The connector is thereby fixed firmly on the frame.

  • Patent number: 5309020
    Abstract: A semiconductor device includes a package substrate, a first IC package having external lead terminals which are downwardly bent with respect to a plane surface of the package and a second IC package having external lead terminals which are upwardly bent with respect to a plane surface of the package. These packages are disposed on one surface of the package substrate parallel to each other. One or more pairs of the external lead terminals of the first and second IC packages, which face each other and are electrically connected with to each other, are disposed on the same mount pads provided on the package substrate. Therefore, wires for connecting those lead terminals can be dispensed with and the other external lead terminals can be connected by simply drawing around wires without providing through holes. In addition, no positional deviation between the two packages, occurs and no solder bridges are created during soldering.

  • Patent number: 5299940
    Abstract: An IC card is disclosed which would not be deformed, and hence, which maintains its quality reliability. A frame is provided to house a substrate which mounts ICs. Panels for protecting the ICs are fixed to the frame by first adhesive material layers. A connector is disposed, in contact with the substrate, between the panels. The connector is fixed to the frame by a second adhesive material layer. This prohibits that external force which acts on the connector at insertion and detachment of the IC card into and from external equipment from acting on the first adhesive material layers. Hence, insertion and detachment of the IC card do not cause deterioration in adhesion between the panels and the frame. Thus, deformation of the ICs due to the external force is prevented, thereby the quality reliability of the IC card being better maintained.

  • Patent number: 5299955
    Abstract: In a portable electrical device, a plurality of engaging portions of a frame on surfaces of the frame are directed in the same direction and engaging portions on two connecting terminals can be brought into engagement with the engaging portions along the same direction. Thus, both of the connecting terminals can be mounted on the frame from the same direction, and the efficiency of the mounting operation is improved and can be automated. Furthermore, deformation of or damage to the connecting terminals, caused by the mounting process, is reduced.

  • Patent number: 5288237
    Abstract: A connector-supporting element of a main frame of an IC card and a sub-frame receive holding parts of a connector. The connector-supporting element has barriers having a height of at least one-half that of the holding parts for receiving the barriers and a force applied in the direction along bonded surfaces of the connector-supporting element and the sub-frame. Oblique surfaces are respectively provided on each of the barriers and there is a positional deviation in the parts.

  • Patent number: 5173841
    Abstract: 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.
