Abstract:
A mask for producing a printed circuit board is defined in which the conductor elements of the printed circuit pattern are delineated by a constant width etch band (20). This means that all conductors (3a, 3b, 9) are separated from neighbouring areas of conductive material (22) by the same distance. Thus etch rates across the printed circuit pattern do not vary according to the separation of the conductors (3a, 3b, 9).
Abstract:
An appliqué for forming a surface coating to a substrate (55) is disclosed. The appliqué contains a sectioned metal foil (20) that provides a large area electrical circuit for connecting electrical devices. The appliqué may provide additional functions including lightning strike protection. The substrate may be an aircraft surface.
Abstract:
A method for manufacturing an antenna and an antenna structure. The traditional built-in antennae have problems that there is an instability of the antenna RF performance due to the variation of the interval between the RF element and the base body on which the RF element is mounted, it is difficult sometimes to manufacture a RF element with a complicated 3-D configuration, and so on. The present invention provides a method for manufacturing an antenna, comprising: providing a base body; by use of the chemically plating process, forming a chemically plated metal layer on the outer surface of the base body; according to the pattern of the antenna, carving the metal layer on the base body at certain portions to form a RF element pattern so that the portion of the metal layer forming the RF element pattern is separated fully from the remaining portion of the metal layer which will be removed later; electroplating the metal layer of the carved RF element pattern formed on the base body with Cu so as to form an electroplated Cu layer on the pattern of the antenna; removing the portion of the chemically plated metal layer on the base body that has not been electroplated. The present invention also provides a corresponding antenna structure.

Abstract:
Illumination assemblies include a substrate having a first and second electrically conductive layer separated by an electrically insulating layer. The insulating layer includes a polymer material loaded with thermally conductive particles. At least a portion of the thermally conductive particles simultaneously contact both the first and second electrically conductive layers. A plurality of light sources such as LEDs or other miniature light sources are preferably disposed on the first conductive layer.
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.
