  • Hi Richard,

     

    I got into trouble when generating gerber files.

     

    The board looked like this.

    image

    (dark red area: polygon of top layer // green area: pad // purple area: copper free part of gnd layer)

     

    After CAM process, I got a cmp file like this

    image

    and a sol flie like this.

    That's strange because components seems unable to be grounded.

    May you give me any suggestion?

     

    Best regards,

    Hi Edith,

     

    the ground layer is an inner layer I suppose. It is defined as a supply layer which is displayed and printed inverted. This means you are not allowed to combine a supply layer with Pads and Vias layers, which you did. Please activate only the supply layer for the ground plain in the inner layer. Then it should be okay.

    In case you want to have a ground plain on the Bottom layer, please use  a GND polygon and generate Gerber data from Bottom, Pads, and Vias.

     

    Hope this helps.

    Regards,

    Richard
