Altium - solder mask sliver
« on: July 14, 2014, 04:44:52 pm »
Hello folks,

I would appreciate your help solving the following Altium problem. I want to be able to ignore the solder mask sliver violation for same net objects. For instance, I want the design rule checker to ignore the minimum solder mask sliver rule for a via and pad of the same net since they are already shorted and I don't care if the solder mask between them isn't present. However, I want the solder mask sliver rule to be violated when the objects are part of different nets. It would be nice if I could create a rule for this, but I'm having difficulties coming up with a custom query to do this. The other possibility would be to ignore specific violations, but I don't think Altium can do that.

Thanks.

We have a specific Altium forum where this should have been posted.  Maybe a mod can move it.

Solder mask slivers are not a problem of lack of isolation. Thin slivers can not be manufactured so the board house will either remove them or reject your data.

I understand, but how do I get the software to recognize the slivers which are too thin only between different net objects and mark them, and only them, as violations.

Is this not more easily spotted by setting up a pad-pad (different net) clearance rule? (as long as you're not doing weird things with soldermask pullback on a per-pad basis).
