Hi there,
I am using V.X. 2.4 and I need to have quite a bit of vias on an IC pad. I have set up a Multiple Vias Object but that only allows me to place a maximum of 21 vias on the pad.
I can place the 21 vias of the MVO pattern fine, so I tried to manually copy/paste the MVO pattern but I get clearance errors.
Is there a workaround to the 21 vias limit? In the xPCB manual on page 25 it says you can change the via count in the Editor->Via count, but setting that fanout to 10 doesn't let me have more vias in MVO.
Without using the fancy MVO feature, there must be a way to add "vias at will" on a pad/track, can anybody help?
Thanks
Flavio
If anyone is having the same issue,
I found that the easiest way to add multiple vias on a IC pad is just to add a via array: Route > Add Via (menu item), Array (tab).
I guess you can either use a specific rule scheme for the pad area (as for the MVO above) or just set the DRC off in the array tab.
Probably the MVO above is worth setting up if you are going to place that vias pattern often - it's probably an overkill for stitching a thermal pad of a single IC.
Hope this helps
Flavio
