Abstract: According to an example, a device may comprise a printed circuit board. The printed circuit board may further comprise a first layer and a second layer. The first layer may comprise a first material and the second layer may comprise a second material. In some examples, the first layer may further comprise at least one mounting hole surrounded by a third material at a thickness equal to a thickness of the first layer, and the first material may be electrically isolated from the third material. In some examples, the printed circuit board may be mated to a light guide assembly for a touchscreen system.
