ABSTRACT:
A double-sided printed circuit board is described with a method for providing selective connection between conductors on the two faces of the board without the use of wire links or bridges. The board carries a plurality of plated-through holes arranged to provide all of the inter-connections which may be required in various combinations in a range of applications. When the actual combination required in a particular application is determined, those inter-connections which are not required are broken by removing part of the plating.
