Abstract:
An IC card has a contact portion which is exposed on one surface of a printed circuit board and has multiple terminals provided to electrically contact an external device. Wirings are arranged on the other surface of the printed circuit board at a position facing the contact portion with the printed circuit board in between, and are printed at least at positions opposite to gaps between the terminals. The arrangement of the wirings thus prevents that portion of the IC card at the gaps from becoming thinner than the other portion of the IC card.
Abstract:
A wiring board on which electronic components are mountable includes a stretchable portion having stretchability and having a first surface and a second surface opposite to the first surface, and an interconnection wire electrically connected to the electronic components mounted on the wiring board. The stretchable portion includes first regions lined up in each of a first direction and a second direction, a second region including first portions and second portions, and a third region surrounded by the second region. The first regions overlap the electronic components. The first portion extends from one of two first regions neighboring each other in the first direction to the other thereof. The second portion extends from one of two first regions neighboring each other in the second direction to the other thereof. The second region has a lower modulus of elasticity than the first region. The interconnection wire overlaps the second region.

A high-current contact device includes a first contact element transmitting electrical energy, a circuit carrier, a first data contact transmitting data, and a data interface. The first contact element extends through the circuit carrier along a mating axis at a feedthrough.

A high-frequency signal transmission line includes an element, a linear signal line provided at the element and including a first end and a second end, and at least one ground conductor provided at the element and extending along the signal line. The element includes stacked insulating layers. The ground conductor is positioned opposite to the signal line with the insulating layer positioned therebetween.

The signal line includes a first section and a second section. The first section is an uninterrupted section generating a characteristic impedance greater than or equal to a first characteristic impedance at the first end and including the first end. The second section generates a characteristic impedance less than the first characteristic impedance and is adjacent to the first section. The second section is longer than the first section. The signal line is wider in the second section than in the first section.

A printed circuit substrate may be configured with at least one internal lead designed and shaped to reduce solder bridging. The printed circuit substrate can have a plurality of internal leads that each has a continuously curvilinear boundary that defines an isolation channel. The isolation channel may be configured with a uniform distance that separates a first internal lead from an adjacent second internal lead.

A touch window includes a substrate, a sensing electrode on the substrate, a wire electrically connected with the sensing electrode, a ground wire adjacent to the wire, and a printed circuit board connected with the wire and the ground wire. An overlap length between the ground wire and the printed circuit board is longer than an overlap length between the wire and the printed circuit board. Alternatively or simultaneously, a line width of the ground wire is wider than an interval or gap between the wire parallel to the printed circuit.

Provided is a configuration for a semiconductor layer and a line for reducing the segment length of the semiconductor layer with respect to the bending direction of the flexible substrate. Such a configuration reduces the probability of cracks occurring in the semiconductor layer of the thin-film transistor, thereby improving the stability and durability of the thin-film transistor employed in a curved or a flexible display device. The configuration includes a thin-film transistor (TF) on the flexible substrate. The TFT includes the semiconductor layer extending obliquely with respect to the direction of the line.
