This application relates to a method and apparatus formed using the method. The method includes using a first process to form at least one conductive trace on a flexible surface and using a second process to form at least one bead of fluid conductive material at a first location. The method also includes positioning at least one printed circuit board overlaying conductive trace such that the at least one bead of fluid conductive material is aligned with at least one hole in the printed circuit board and pushing the printed circuit board towards the flexible surface. The pushing of the printed circuit board toward the flexible surface forces the bead of fluid conductive material through the hole to form an electrical connection between the at least one conductive trace and an upper surface of the printed circuit board.
