  • Two-layer capacitive touchpad and method of making same
    Patent number: 6188391
    Abstract: By suitable use of screen-printed carbon ink patterning, combined with patterning of the solder-mask layer on the top (finger) surface, a compact capacitive touchpad pointing device has been realized using only a two-layer board as a substrate. The first layer, on the topside of the printed circuit board, combines both the horizontal and vertical sensor electrode traces. The second layer, located on the underside of the printed circuit board, is formed in the conventional manner by attaching the controller chip and/or related circuitry.
