ABSTRACT:
An improved flexible substrate for a touchpad, with the flexible substrate having conductive ink for forming a sensor array. A printed circuit board is also used, but only for the components which need to connect to the array, and not the array, thus giving a smaller printed circuit board. The printed circuit board can have the components compactly mounted on it taking advantage of the close spacing available in PC board technology. The PC board itself has wider spacing on its contacts at its outer edges, allowing it to be attached by conductive glue to the flexible substrate.
