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.
