Double vias for high current tracks in Orcad 17.4 PCB Designer Standard

Ntyler

Hi,

We have some thicker 50mil tracks that need higher current capability.
I want to 'double up' on vias for these tracks, but OrCad won't allow stitching through the board with both vias. See below:



If I try to route both top and bottom layer tracks through both vias, one of the other tracks is always deleted.
This means that only one via is ever effectively connecting the two tracks through the board.



Can anyone help with how to do this please?

I found this video, which at 1:24 briefly alludes to Place>Via Array>Array Parameters>Centred, and this looks like maybe it could be relevant - but this option doesn't appear to be available in PCB designer standard.

Any suggestions please?

Thank you
Nick

    By default, routing Options have Replace Etch enabled which will remove any redundant routing. Get into a routing operation, like Route>Connect, and then uncheck Replace Etch in the Options pane. Note that, unless changed back, the Replace Etch Option will be remembered for future routing operations.
