Abstract: A method for mass producing thin IC cards having beautiful surfaces using a non-polluting polyethylene telephthalate material in which a hot-melt type adhesive is applied and formed on a joint surface of a cover sheet formed from polyethylene telephthalate, and in which a hot-melt adhesive is used as a sealing adhesive at an opening of a core sheet that is held by the cover sheets. To improve the heat-resisting bonding strength of this hot-melt adhesive, a thermosetting resin may be mixed with the hot-melt adhesive.

Abstract: In an IC card, a frame for connecting a board for mounting electronics components is covered by upper and lower panels. A main connector for connecting the IC card to a computer is provided at one end of the frame. Further, one or more subconnectors to be connected to external systems are provided on the board and the pins of the subconnectors extend towards openings in the upper panel. The subconnectors are supported between the board and the upper panel. Thus, various kinds of subconnectors for various functions can be used with the IC card. In a modified example, a subconnector is provided opposite the main connector on the upper panel, and the pins thereof extend in a direction parallel to the board.

Abstract: A non-contact IC card and a method and apparatus for manufacturing the IC card. The IC card has a small thickness and is manufactured at a low cost, automatically. Electronic parts are mounted on a circuit pattern on a surface of a resin sheet. A filling resin covers the elcetronic parts and fills gaps between them. An electronically insulating plastic material on the filling resin wraps around the filling resin, contacting its side surfaces and saide surfaces of the resin sheet. The plastic material provides added protection to the electronic parts. In a method of manufacturing the non-contact IC card, the laminated structure of the resin sheet, filling resin, and plastic material is subjected to two sequential severing steps. In the first severing step, only the resin sheet and the filling resin are severed, generally in the shape of an IC card that is to be completed.

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.

Abstract: Cracks in solder connecting terminal leads of an IC to a circuit board are prevented by reducing the stress due to the difference in the coefficients of thermal expansion of a pair of IC packages mounted on opposite surfaces of a circuit board and the circuit board. In this invention, the position of an IC package mounted on the upper surface of a circuit board is spaced from the position of an IC package mounted on the lower surface of the circuit board. Alternatively, the IC packages are mounted on the upper and lower surfaces in directions which are substantially orthogonal. Alternatively, the IC packages are mounted such that the positions of lead portions of one of the upper IC packages are spaced from the positions of the lead portions of the other IC package by a distance which is at least 2.4 times the thickness of the circuit board.

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.

Abstract: A semiconductor device card includes a frame on which a semiconductor module may be mounted and a protection panel adhered to the frame. The frame includes pairs of offset grooves along each of two opposed sides and the protection panel includes pairs of offset flanges along each of two opposed edges of the panel. The protection panel flanges are inserted into the grooves in the frame and adhered to the frame in the grooves. Thus, a large attached area for ensuring good adhesive strength between the frame and the protection panel is achieved.

Abstract: A printed circuit board includes a printed wiring board and a terminal board bonded to the printed wiring boards. These boards contain reinforcing fibers, and the directions of the reinforcing fibers in both boards are the same whereby coefficients of thermal expansion of both boards are substantially equal to each other. Thus, it is possible to prevent the circuit board from bending and to get a planar arrangement of electrode terminals in a case where the terminal board is bonded to the printed wiring board with solder.

Abstract: A semiconductor device mounted on a substrate. Outer leads, partially resin-molded, have a greater height above the mounting surface than that of a conventional device. Specifically, each lead projecting from the molded resin has a bent portion which is convex in the direction opposite to the mounting surface, and the length of the lead beyond the bent portion is greater than the distance from the lead portion adjacent to the resin portion of the lead to the mounting surface. The long leads improve reliability during, e.g., heat cycle, tests. In another embodiment, outer leads, partially resin-molded, have reverse J-shaped bent portions, each with a distal end positioned away from the resin. When the bent portions serve as soldering portions, the soldering condition can be easily checked.
