1. A touchpad with printed circuit board (PCB) structure, comprising:
- a single substrate PCB having a bottom surface;
a sensor area disposed on the bottom surface, the sensor area including a plurality of first and second directional traces, whereby the first and second directional traces are interlaced and disposed in coplanar manner on the bottom surface; and
a component area disposed in coplanar manner on the bottom surface peripherally outside the sensor area, the component area being operably coupled to the first and second directional traces.
