multi drill pads and plane void anomoly

padmaster

I'm having trouble getting the internal planes to fill properly around pads with multi drills. see images.

Some planes fill properly, some don't. Some have mysteriously corrected themselves.

I've tried picking up the plane and dropping back down....that doesn't work.

I've looked over the padstacks and can't find any problems there.

Anyone know how to correct this?

    Hi,

    I think your problem is in your padstack. You have defined a padstack with multiple drills in a square pad. The square pad is expanded thru the cross section. What I would suggest is

    creating the square pad as a surface mount pad and adding the vias in the package symbol.  

    I believe you will get the results you are seeking.
