Abstract
A triggering condition is applied to a conductive polymer positioned in a drilled hole in a printed circuit board. The applied triggering condition causes the polymer to vertically expand 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.
Claims13
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.
A printed circuit board comprising a conductive polymer positioned in a drilled hole in the printed circuit board, the conductive polymer configured, responsive to an applied triggering condition, to vertically expand 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.
