Abstract:
A wiring substrate (1) includes a substrate (10), a first insulating layer (20) formed on the substrate (10), wiring patterns (30) formed on a first surface (R1) of the first insulating layer (20), and a second insulating layer (50) formed on the first surface (R1) of the first insulating layer (20). The second insulating layer (50) covers the wiring patterns (30) and includes a first opening (50X) that partially exposes adjacent wiring patterns (30) as a pad (CA). A projection (70) is formed in an outer portion of the substrate (10) located outward from where the first opening (50X) is arranged. The projection (70) rises in a thickness direction of the substrate (10).

Abstract:
To provide an electronic device on which semiconductor packages can be mounted efficiently. The electronic device comprises a board (1) that can receive a plurality of first semiconductor packages (P0-P8) each carrying a processor device and a plurality of second semiconductor packages (M0-M8) each carrying a memory device. Mount regions (3) where the packages are to be mounted and non-mount regions (4) are alternately arranged in rows and columns on the board (1). This ensures approximately equal wiring distances between the packages, allowing processor devices to access to memory devices at the same timing.
Abstract:
In a drive IC and a display device having the same, the drive IC includes a plurality of bumps disposed on a lower surface of the drive IC and aligned in a plurality of rows along an edge of the drive IC. The bumps aligned in different rows from each other are juxtaposed in a direction perpendicular to a direction in which the bumps are aligned. Accordingly, when the drive IC is mounted on a display panel using an anisotropic conductive film, the anisotropic conductive film may be smoothly flowed through a space defined by the bumps of the drive IC, thereby improving electric properties of the drive IC and display device.
Abstract:
An article and method for making and repairing connections between first and second circuits, such as flex circuits. The article (10) includes: a flexible dielectric substrate (12) having first and second edges 14/16, and a plurality of conductive circuit traces (18) arranged on or within the substrate, wherein each of the traces extends from proximate the first edge (14) to proximate the second edge (16). Each of the circuit traces (18) includes: a first connection feature (20) disposed proximate the first edge (14); a second connection feature (22) disposed proximate the second edge (16); and at least one third connection feature (24) disposed between the first and second edges (14/16). Each of the first, second, and third connection features (20/22/24) is a plated through hole, a plated blind via, or a mounting pad. This article (10) may be used to connect together the first and second circuits (50/60) using the first and second connection features (20/22), such as by soldering. If either of the two circuits needs to be subsequently detached (e.g., because of a component failure), the article (10) may be cut so as to present a set of third connection features (24) to which a new replacement circuit may be connected.
Abstract:
An insulation displacement contact (10) comprises first and second contact portions each of which comprises a cantilevered split beam (19). The upper split beam, which receives insulated wires, comprises a pair of tynes (20,22) which are folded about the axis of a slot (25) separating the tynes such that the internal angle between the tynes is approximately 90°. The width of the tynes is larger than that of prior art devices resulting in increased stiffness and the length of the tynes is sufficiently long to receive two wires therebetween. The contacts (10) are mounted in a housing which includes a plurality of teeth (90) provided with means for retaining lugs (32,34) on the end of the tynes to ensure bowed opening of the tynes on insertion of a wire. The contacts are arranged along the central axis (72) of the housing such that the folded tynes of alternate contacts extend on opposite sides of the central axis.
Abstract:
Un système de connexions électriques, par exemple un tableau de connexions à face rabattables, comporte un profilé de support (12) recevant des premiers connecteurs (14) dont les contacts sont orientés vers l'extérieur du profilé (12). Un câble introduit entre le profilé et les connecteurs se divise en conducteurs individuels aboutissant à des contacts (34, 36) via des fentes (30) dans les parois du profilé. Un second connecteur (16) porte des prises de communications vocales ou de données classiques (19) qui sont reliées aux premiers connecteurs par l'intermédiaire de cartes de circuits imprimés (38) qui s'enfichent dans des fentes (40) des premiers connecteurs. Les connecteurs plats des cartes ont une discontinuité sur une surface, et une moitié du contact est reliée au contact sur l'autre face pour permettre une connexion directe entre les rangées de contacts supérieures (34) et inférieures (36) des premiers connecteurs dans une première position des seconds connecteurs, et permettre également un contact entre les rangées de contacts supérieures et inférieures et les prises classiques (19) dans une seconde position.
