The first circuit board has at least one conductive feature proximate the aperture, and the second circuit board has at least one conductive feature proximate the edge. Each board has at least one circuit trace in electrical communication with its respective conductive feature. The conductive features of the boards are placed in electrical communication with each other by way of the edge of the second board being disposed in the aperture of the first board. A solder joint can be disposed on the assembly so as to connect the first and second boards.
Abstract:
A printed board (5) for mounting electronic component, a method for making the same, and an arrangement for connecting a conductive elements (8, 8′) to the printed board are provided. The printed board includes an insulating substrate (50), and at least one metal terminal (53, 54). The substrate is formed with at least one opening (51, 52) penetrating the substrate. The metal terminal is fixed to the substrate so as to bridge the opening, without projecting out of the substrate.
Abstract:
A protector cartridge circuit arrangement which permits more robust line protection. The circuit arrangement has high-capacity and large-sized components staggered across the surface of a printed circuit board such that high-capacity components can be used in the cartridge to protect plural, adjacent lines. Such devices cannot be used in pair-at-a-time protectors because of space constraints. A preferred industrial application is the protection of communication lines.
