I have Blind Vias (LAYERS 1-8) and (LAYERS 13-20) stacked on top of
each other. I also have mask to mask clearance in constraints set to 4 mil. Problem is that I get Mask to Mask DRC for overlapped top and bottom blind vias. Mask for top via defined on top. Mask for bottom via defined on bottom. In Padstack definition Xsection not showing all layers. Also, what is Default Internal layer there for? Any input about the BB definition and / or Mask to Mask violations? Thanks, Mark Please see attached definitions. |
