I am designing circular capacitive touch pads of Dia:20mm driving from TTP224 IC on my PCB. There will be 2mm glass panel above Touch pads. My PCB contains other circuits like Arduino, Antenna bands and driving LED's as well along with these touch pads. These 4 touch pads are at different positions (They are not side by side).
Will the tracks (Track width:10 mils) from touch pads to the TTP224 IC when touched will detect the touch or only touch pads will detect the touch? (I don't want tracks to detect the touch).
Can I place common copper ground pour on PCB's opposite layer of that of touch pads?
Can I place Antenna bands (of Bluetooth/WiFi) on PCB's opposite layer of that of touch pads?
Can I place any other IC's or components (Like TTP224, RC's etc.) on PCB's opposite layer of that of touch pads?
What maximum diameter I can take as touch pads?
