Hi
Our customer considers capacitive touch using Captivate.
They had question about stackup.
Please see below file.
In their system, a gap between sensor sheet and PCB is ~10mm.
MCU, LED and all electrical components would be on PCB.
1.
Do you have any concern for this stackup?
2.
Ground planes would be only on PCB.
Could you please tell us layout recommendation in this case?
BestRegards
