    MBR3, Minmum width of shield electrode

    user_474444345

      Hello,

       

      I have 2 questions.

       

      Q1)

      In old type of CapSense Design Guide, the below was recommended. I can not download the document anymore now, So I picked up the picture from Japanese ver.

      In the documentation, the maximum shield width is shown as 1cm. However, there is not described minimum width.

       

      図4-13.シールド電極パターン.png

       

      In other chapter, there is described that Hatch pattern should be 0.17mm trace and 1.143mm grid (25% filling)

      If we can satisfy this condition, can we take any shield electrode width?

       

      Q2)

      How much space is needed between Shield electrode and PCB Ground Plane.

       

      Best regards,
