Design Guidelines

The below sections describes the guidelines to design mutual-capacitance sensor patterns for long slider. Both the One-layer (Coplanar) and Two-layer (Flooded X) patterns can be used to design long slider sensor.

Schematic and PCB layout guidelines for QTouch PTC design can be referred in the application note PTC Robustness Design Guide in sections ‘Schematic Design’ and ‘PCB Design’.
