Via-in-Pad on old Orcad Layout 16.2

Temistocle

Hi, I am still using Orcad Layout 16.2.0, and I need to use via-in-pad on the next PCB.

I changed the pad attributes of a SMD 0805 resistor, checking the "Allow via under pad" setting in the footprint.

But how I can put the vias under the pads of this footprint in the PCB? I only get errors like "Via will not fit".

Thank you in advance

M.

    This seems to be working fine for me and I only get the "Via will not fit" for conflicts with other routing. Quite likely getting the Vias into the pads may be the least of your concerns since OrCAD Layout has a limited number of Via Types and DRCs for "nested" Vias is limited, it also doesn't handle rules by regions and other things that are going help when working with Via in Pad and Blind / Buried Vias in "tight" designs. It may be possible that getting hold of another PCB tool, like PCB Editor, might make your efforts with this type of design more productive.

    Hi oldmouldy, thank for your reply. It seems that now it works fine, after a "close-restart" of Layout. I will switch to PCB Editor in the future, but since it has a lot of differences from Layout, I need some time to learn it. Thank you again.
