Abstract:
A flexible circuit includes a flexible non-conductive substrate (12) having a first surface and a second surface. A first electrically conductive trace (18) is provided on the first surface and a second electrically conductive trace (20) is provided on the second surface. A passage (22) extends through the substrate from an end of the first trace to an end of the second trace. The passage includes a beveled opening (26) of a first size formed in the first side and axially aligned with a second beveled opening (28) of the first size formed in the second side. The first and second openings are interconnected by an aperture axially aligned therewith and being of a second size less than the first size. An electrically conductive surface is provided on the passage for electrically interconnecting the first trace and the second trace.
Abstract:
The present invention pertains to a data medium in the form of a chipcard comprising the card body (1) fitted with an antenna (3), a chip module (2) containing an integrated circuit (10) and located in a recess (5) provided in the card body (1). The electric connection between the antenna (3) and the chip module (2) passes through lows (11) in the antenna (3) connections (4). When manufacturing the inventive data medium, a cavity (5) is engineered inside the body card (1) in which the antenna is at least partially embedded. The chip module (2) is placed into said cavity (5) and glued to the card body, for example with a thermoactivable glue (6), thereby establishing an electric connection between the chip module (2) and the antenna (3) inasmuch, for instance, as a conductive glue is used for anticipated application to the free antenna (3) connections (4). In the preferred embodiment the chip removal is carried out so as to form an oblique cutout.

PROBLEM TO BE SOLVED: To solve the problem wherein solder is hidden behind an electrical element in a conventional flat electric element, it is difficult to detach a defective element and rework is difficult as a result, while the defective element is sometimes detached by manual work using a soldering iron, in order to detach a defective mounted element from a printed board and exchange it, after mounting the printed board. SOLUTION: A coin-shaped battery 20 with leads is provided with bend parts 22a and 23a by bending the respective two leads 22 and 23 in a direction of crossing main surfaces 21a and 21b, in a region farther inside than the edge of the main surfaces 21a and 21b of a coin-shaped battery 21.

Abstract:
PROBLEM TO BE SOLVED: To provide a via contact structure capable of minimizing a loss to high frequency. SOLUTION: In a printed circuit board or a package forming an insulating layer and a large number of circuit layers, a skew via is formed so as to skew to the circuit layer surface and form an obtuse angle to an electric power and a signal line. This is a signal transmitting device using the skew via formed so as to skew to the circuit layer surface and form the obtuse angle to the signal line, in a signal transmitting device between a first and second conductive wires locating on independent first and second circuit layers. The problem of signal failure due to high frequency generated by the high speed of a digital signal can be solved. By a substrate such as the IC package or the PCB having a via contact structure, the high frequency loss in the via contact can be reduced and the signal transmission in a future high frequency band can be improved.

Abstract:
An electronic component unit and a wire harness are provided with a bus bar plate. The bus bar plate is provided with a metallic bus bar that is built in a resin material, and including a through-hole in which a terminal of a relay mounted on a mounting surface is soldered. The through-hole is provided with a bus bar through-hole which penetrates the bus bar, and a resin material through-hole which penetrates the resin material and is formed to be larger than the bus bar through-hole to expose the surface of the bus bar. When an inner diameter of the bus bar through-hole is defined as r and an inner diameter of the resin material through-hole is defined as R, 1.5r≦R is satisfied.
