Abstract:
The present invention is to provide a printed wiring board which can certainly prevent damage of conductive pattern caused by the terminal. The printed wiring board has a board, a conductive pattern, a through-hole and a non-conductive area. A lead wire of resistance mounted on the printed wiring board is inserted into the through-hole 4. The lead wire projects from a surface of the board, and is bent close to the surface. The non-conductive area is formed into a fan-shaped shape enlarging toward a tip of the lead wire from a center of the through-hole. Since the bent lead wire is arranged on the non-conductive area, the non-conductive area can prevent damage of the conductive pattern which is caused by touching the lead wire to the conductive pattern.
Abstract:
Bereitgestellt wird eine Adapterplatte (1) für HF-Strukturen, die dazu eingerichtet ist, zwischen einer Rückseite einer Leiterplatte (2) und einem Reflektor (4) angeordnet zu werden, wobei die Adapterplatte elektrisch leitfähig ist, und die Adapterplatte an jeder Stelle, an der ein Element durch die Leiterplatte auf die Seite der Adapterplatte durchgeführt ist, eine Öffnung (102) oder eine Vertiefung (101) aufweist, wobei mindestens ein Element ausschließlich zur Massekontaktierung durch die Leiterplatte geführt ist.
Abstract:
In accordance with the various embodiments disclosed herein, an improved electrical connector footprint, such as on printed circuit boards (PCB), is described. For example, antipads can have a variety of sizes and pairs of differential signal traces can define centerlines that are spaced apart from each other.
Abstract:
A multilayer wiring board includes: a first differential wiring (30A) wired to a third signal layer (3C); and a second differential wiring (30B) wired to a ninth signal layer (3I). The multilayer wiring board includes a first differential signal via (12A) and a second differential signal via (12B) that are connected to the first differential wiring. The multilayer wiring board includes a third differential signal via (12C) which is connected to the second differential wiring and a stub (41) of which is terminated above the third signal layer. The multilayer wiring board includes a fourth differential signal via (12D) which is connected to the second differential wiring and a stub of which is terminated above the third signal layer, the first differential wiring wired to pass between the fourth differential signal via and the third differential signal via.
