Hi Sirs

Should we clear PCB copper layers under the crystal when we do to layout?

Thank you for your great support.

    Hello,
    I don't clearly understand what do you mean by "clear copper layers" but you have to provide a solid GND plane to the crystal circuit, this plane should cover all the components of the crystal circuitry and it should be isolated from other GND planes.
