1. A flex circuit for connecting to both sides of a touch sensor panel, comprising:

  • a base film shaped to form first and second attachment areas;

    a layer of conductive traces formed on a single surface of the base film and terminating with conductors in the first and second attachment areas, the conductors shaped and located for making electrical connections with first and second sides of the touch sensor panel; and

    an insulator formed over the conductive traces and conductors;

    wherein the base film, conductive traces and insulator form a flexible stackup capable of being folded for attachment to the top and bottom sides of the touch sensor panel.
