Capacitive touchpad and method for forming the same |
摘要 |
A capacitive touchpad comprises a membrane and a printed circuit board combined together. The membrane comprises an X trace and a Y trace with an insulator layer inserted therebetween, and the printed circuit board has connection pads on a top side of a substrate that are electrically connected to the X and Y traces. The printed circuit board further comprises vias connected between the connection pads and a conductor layer on the bottom side of the substrate. To form the capacitive touchpad, the membrane and printed circuit board are individually produced in advance, and then combined together. Alternatively, the membrane is printed on the printed circuit board.
