Abstract:
The present invention provides a PWB for attaching electrical components thereto. The PWB includes a stack of insulating layers, conductive layers located between the insulating layers, wherein the conductive layers terminate at an edge of the PWB, and an edge plate interconnect located on the edge. The edge plate interconnect is free of a complementary via and contacts and electrically interconnects the conductive layers. The present invention also provides a method of making the PWB and also provides a power converter implementing the edge plate interconnects.

Abstract:
A printed circuit has additional connections formed on one of its faces by depositing beads of conductive resin on that face. The conductive beads are covered by an insulating coating, and, if required, further conductive beads may be deposited on the insulating coating formed on the first beads.
Abstract:
A substrate (1,2,3) for mounting an electronic component (6) or components thereon. The substrate comprises a core substrate (20) and at least one insulation layer (22,22') on at least one side of the core substrate, and a patterned wiring line layer (24,24') formed on at least one insulation layer. The core substrate (20) includes holes (26a) in each of which a lead pin (6a) of an electronic component (6) may be inserted, and is provided with lands (10) each of which surround the opening of a hole and to which the lead pin (6a) inserted in the hole is bonded. The insulation layer (22,22') or layers has bores (11), which expose the land at their bottom ends, and thereby communicate with the holes. A method of manufacturing such a substrate is also disclosed.
