From the documentation, i found this recommended layer stackup:
1. Cap sensors
2. Sense traces
3. Hatched ground plane
4. PSOC and non-capsense related traces
My question is this - should layer 2 have a ground plane around the sense traces, or should layer 2 consist of ONLY the sense traces, and no other copper?
Solved! Go to Solution.

Hello Ari,
Use the following guidelines for 4 layer PCB
1. Top layer - Hatch fill and sensors
2. 2nd Layer - Only sensor traces, no hatch fill
3. 3rd layer - Hatch fill
4. Bottom layer- PSoC and non capsense trace
