    Abstract: A power converter including a printed circuit board (PCB) having a plurality of heat conductive layers configured to sink heat generated by the power converter electronics. Each of these heat conductive layers are comprised of thermally conductive material configured as planar sheets, each of these heat conductive layers being coupled to at least one wire to sink heat therefrom, such as via a wire of an input cable and/or output cable. Advantageously, a more compact power converter is realized having improved power output while operating within safety guidelines.

    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 neighboring 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: A method for manufacturing printed circuit boards has a double etch process to form interconnection wiring. A metal layer is formed on the substrate. An etch resist layer is applied to the metal layer. The layer is selectively removed to allow for selective etching of the metal layer. A second etch resist layer is applied to the metal layer not previously etched. The side walls of the metal layer are also protected by the resist. The second etch resist layer is then selectively removed to allow for a second etching of the metal layer. After the second etching, the interconnection wiring remains in the desired pattern. The second etch resist layer, which may be tin, can be left on the wiring to improve component soldering.

    Abstract: A process for providing a dielectric substrate with a composite surface comprising a metal plated portion side-by-side an unplated portion. The process includes: depositing a metallic film over the surface of the substrate; removing a narrow band of the film to electrically isolate one portion of the film from another; immersing the substrate in an electroplating bath capable of dissolving the film; cathodizing one of the film portions in the bath to electroplate that portion while the other portion dissolves therein to expose the underlying substrate. The thusly exposed substrate may subsequently be painted.
