Abstract
A method for electrically connecting a surface conductor to an edge conductor on an intersecting side of a non-conductive substrate, includes the steps of forming a through-hole in the substrate, and metallizing the through-hole to form a conductive via. Then, the substrate through the via is cut to form an intersecting side. An electrical connection may be made between a surface conductor through the via to an edge conductor on the intersecting side of the substrate. A preferred embodiment further includes forming an insulating sealing plug in the via, prior to cutting the intersecting side. The above method provides an edge connection without the need to wrap a conductive conduit around the corner of the substrate. Such wrap-around conduits are vulnerable to damage during subsequent handling of the substrate.
