Claim of US Patent No. 10,772,215

1. A computer program product comprising a computer readable storage medium, wherein the computer readable storage medium is not a transitory signal per se, the computer readable storage medium having program instructions embodied therewith, the programs instructions configured, when executed by at least one processor, to cause the at least processor to perform a method comprising:sending a command to apply a triggering condition to a conductive polymer positioned in a drilled hole in a printed circuit board to vertically expand the polymer within the drilled hole such that the expanded polymer creates an electrically conductive path between contact pads located in different layers of the printed circuit board.
