Good morning. There is always help from the community. Thank you : )

This time, while checking the CapSense PCB Layer document, please contact us if you have any questions. What percentage is the percentage fill shown in the image below? How do you design the Hatch Ground with the percentage stated in the actual design? Thank you.

Hi @kain_4812361 , The image shows the top layer of the PCB with capsense sensors on it. Therefore, the hatch fill should be 25 %, (ie), the spacing between the traces should be 45 mils. Please check the sample layout designs from our development kits for reference.

Please check with your manufacturer vendor on how to realize these  hatch pattern in the PCB.
