Abstract:
A device includes a printed circuit board substrate, an antenna connected to the printed circuit board substrate, an amplifier connected to the printed circuit board substrate, and a matching track having a first end electrically connected to an input of the amplifier and a second end electrically connected to an output of the antenna. The matching track has an outgrowth that is symmetrical along a median axis of the outgrowth. The matching track is rectilinear and has a constant width over an initial part extending between the widening area and the first end. A median axis of the initial part and the median axis of the outgrowth form an angle comprised between 60 and 120°.
Abstract:
A printed circuit board assembly includes a printed circuit board, a number of electronic components mounted thereon, and a number of conductive traces electrically connecting the components to form a number of transmission channels. Each of the channels has first and second transmission routes for transmitting differential signals. Each channel includes a common mode choke, a pair of capacitors, and an autotransformer. The common mode choke includes a first coil series connection with the first transmission route and a second coil series connection with the second transmission route. The capacitors include a first capacitor series connection with the first transmitting route and a second capacitor series connection with the second transmitting route.
Abstract:
A flexible flat circuit includes a pair of insulation sheets, and a plurality of conductors that are held between and covered with the pair of insulation sheets in a state that the plurality of conductors are separated to each other. Among from the plurality of conductors, at least conductors with different current capacities are different in thickness to each other.
Abstract:
A flexible conductive track arrangement has a pre-flexing condition in which the arrangement is generally planar. Conductive tracks are formed from a metal layer and they are covered above and below by insulator layers. The elongate conductive tracks are generally planar but locally corrugated perpendicularly to the general plane. This enables improved binding performance, for example to form tight windings using the conductive tracks.
Abstract:
A broadside coupled differential design is described herein. The design may include a differential pair. Each trace of the differential pair includes a wide portion and a narrow portion. The wide portion of the first trace of the differential pair is to be aligned with a narrow portion of the second trace of the differential pair. Additionally, the wide portion of the second trace of the differential pair is to be aligned with a narrow portion of the first trace of the differential pair, such that the wide and narrow portions of the traces of the differential pair are staggered.
Abstract:
The present invention provides a routing structure and display panel. The routing structure includes a plurality of routing, disposed separately. Each routing corresponds to a symbol, and the symbol is disposed on the routing to act as a part of the routing to conduct electricity. In this manner, the routing structure and display panel of the present invention allow expansion of routing width, effectively reduce RC constant and energy-consumption, and improve yield rate.
Abstract:
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.
Abstract:
A method of making an imprinted micro-wire structure includes providing a substrate having an edge area and a central area separate from the edge area and providing a first stamp and a multi-level second stamp. A curable bottom layer and multi-layer are provided on the substrate. A bottom-layer micro-channel is imprinted in the bottom layer. A multi-layer micro-channel and a top-layer micro-channel are imprinted in the multi-layer. Micro-wires are formed in each micro-channel. The bottom-layer micro-wire extends from the central area into the edge area. The multi-layer micro-wire contacts the bottom-layer micro-wire in the edge area. The top-layer micro-wire is over the central area and is separate from the multi-layer micro-wire and the bottom-layer micro-channel. The bottom-layer micro-wire is electrically connected to the multi-layer micro-wire and is electrically isolated from the top-layer micro-wire.
