A FLEXIBLE CIRCUIT WITH CONDUCTIVE VIAS AND A METHOD OF MAKING

摘要

A flexible circuit includes a flexible non-conductive substrate (12) having a first surface and a second surface. A first electrically conductive trace (18) is provided on the first surface and a second electrically conductive trace (20) is provided on the second surface. A passage (22) extends through the substrate from an end of the first trace to an end of the second trace. The passage includes a beveled opening (26) of a first size formed in the first side and axially aligned with a second beveled opening (28) of the first size formed in the second side. The first and second openings are interconnected by an aperture axially aligned therewith and being of a second size less than the first size. An electrically conductive surface is provided on the passage for electrically interconnecting the first trace and the second trace.
