Silkscreen to Soldermask Clearance Rules

AD13 Introduced Silkscreen to Soldermask Clearance Rules.

This library part has soldermask defined pads.




3D View






















The clearance violations are due to the soldermask defined pads (where soldermask swell is less than the pad size) .


Out of the box rule shown below.

Work Around:

Check Clearance to Solder Mask Openings


And use:

(IsText OR IsTrack OR IsArc OR IsFill)
     
OnTopSolderMask Or OnBottomSolderMask 

As shown above I used a 3 mil Clearance rule. If the soldermask swell is 4 mil then this would be the same as a silkscreen to pad clearance rule of 7 mils.


That's It !
