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.

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.

Abstract:
An exemplary printed circuit board includes a substrate, a differential transmission line, and at least two weld pad pairs. The differential transmission line and the at least two weld pad pairs are disposed on the substrate. The differential transmission line includes two parallel signal conductors disposed on the substrate. Each of the two signal conductors is electrically connected to an edge of one of the weld pads of a respective pair of the at least two weld pad pairs. Thereby, the two signal conductors of the differential transmission line can extend in the same distance anywhere, particularly in the position where the two signal conductors pass the two weld pad pairs. As a result, the coupling performance and the capability of the differential transmission line to resist electromagnetic interference are both enhanced.

A wiring substrate of the present invention includes such a structure that a plurality of connection pads and leading wiring portions connected to the plurality of connection pads respectively are arranged to an insulating layer of a surface layer side, and the leading wiring portions are arranged to be bended from the connection pads, and a solder layer to protrude upward is provided on the connection pads respectively. A solder on the leading wiring portions moves to the bend portion side, and thus the solder layer to protrude upward is formed on the connection pads.
Abstract:
A strengthened semiconductor die substrate and package are disclosed. The substrate may include contact fingers formed with nonlinear edges. Providing a nonlinear contour to the contact finger edges reduces the mechanical stress exerted on the semiconductor die which would otherwise occur with straight edges to the contact fingers. The substrate may additionally or alternatively include plating traces extending at an angle from the contact fingers. Extending at an angle, at least the ends of the plating traces at the edge of the substrate are covered beneath a lid in which the semiconductor package is encased. Thus, when in use with a host device, contact between the ends of the plating traces beneath the lid and contact pins of the host device is avoided.
Abstract:
A circuit board includes a signal plane and a ground plane. The signal plane is configured to have a plurality of signal traces arranged thereon. Each of the signal traces includes a plurality of straight line segments. Each line segment extends along a path different from the others. The ground plane includes a plurality of tiles connected in an array. Each tile is formed by ground traces. The straight line segments of each signal trace mapped on the ground plane are arranged at an angle relative to any one ground trace of the tiles. The angle is defined within a range determined by one of ground traces of a tile and an adjacent diagonal line of the tile. A method for laying out such a circuit board is also provided.
