Abstract:
The invention relates to a fitted and soldered printed circuit board (1) of a flat assembly on which an additional component (2) is subsequently added and soldered. The printed circuit board has two solder-free fixing holes (7, 8) to fix the ends of the leads (4, 5) of the additional component (2), between which two interspaced soldering pads (10, 11) are placed, enabling said additional component (2) to be fixed onto the printed circuit board (1) and to be electrically connected. The leads (4, 5) have an area (12) running parallel to the surface of the printed circuit board (3) and a second area (14) running perpendicular to said surface, which are inserted into both fixing holes (7, 8).
Abstract:
A method for producing contact pads on pattern boards (8) comprises a plating treatment in order to apply electrically conductive material on the board in correspondence to the desired contact pads (31). The electrically conducting material on the contact pads is subjected to a treatment with an agent capable of etching the material in order to provide chamfering or rounding of peripherical edges (34) of the contact pads.
Abstract:
Lichtmodul, umfassend eine erste Leiterplatte (10) und eine zweite Leiterplatte (20), wobei auf der zweiten Leiterplatte (20) zumindest eine Lichtquelle (21-23) angeordnet ist. Die erste Leiterplatte (10) und die zweite Leiterplatte (20) sind unter einem Winkel, welcher durch die jeweiligen Leiterebenen der ersten und zweiten Leiterplatte (10, 20) eingeschlossen ist, zueinander angeordnet und über zumindest ein Federkontakt-Element (30-35) elektrisch leitend miteinander verbunden. Der Winkel (8) zwischen der ersten Leiterplatte (10) und der zweiten Leiterplatte (20) liegt zwischen 45° und 135°, liegt bevorzugt zwischen 80° und 100° liegt und beträgt besonders bevorzugt 90°.
Abstract:
Described herein are conductive yarn electrical interconnection arrangements, wherein a conductive thread is conductively attached to an electrical contact on a printed circuit board by locating a conductive portion of the conductive thread in a conductive connection member hole on the printed circuit board and effecting an electrical connection by way of a conductive connection member that holds the conductive portion in place and is in conductive contact with said electrical interconnection. There is also provided processes to make said conductive yarn electrical interconnection arrangements.
Abstract:
A substrate has a first dielectric layer; a first conductive layer on the first dielectric layer; a second dielectric layer on the first conductive layer; an elongated signal conductor embedded within the second dielectric layer; a second conductive layer on the second dielectric layer; a first conductive groove and second conductive groove through the second conductive layer, the second dielectric layer, the first conductive layer and into the first dielectric layer and extending continuously along the length of and on opposing sides of the signal conductor, the grooves having conductive side walls providing an electrical connection between the first conductive layer and the second conductive layer; first and second conductive end walls joining the first groove and second groove; and at least one insulating area through at least one of the first and second conductive layers to provide conductor access.
