ABSTRACT:
Discloses a method for making a coaxial conductor interconnection circuit board, as well as the board per se, by providing a first conductive coating on a substrate, scribing an insulated wire signal conductor pattern on the first coating and a second conductive coating over the wire to provide a conductive shield surrounding the wire, eliminating conductive material from the coatings in clearance areas at terminal points and drilling at the terminal points by laser beam or mechanical drilling to expose the signal conductor.
