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.

Printed circuit board

According to an example, a device may comprise a touchscreen light guide assembly, a lens disposed on the touchscreen light guide assembly, and a printed circuit board including a relief cut on an edge of the printed circuit board. The relief cut may be to receive the touchscreen light guide assembly and to allow the lens to extend into the printed circuit board relief cut.
