Purpose

Circuit elements that are too close may bridge during imaging, etching, plating or soldering, and result in a direct short.

Function

Reports circuit elements located in the same layer that are closer than the action parameter pp_spacing.

Also reports if one element is fully covered by Solder Mask and the other element is fully exposed in the matching Solder Mask layer.

Measurement is a spacing segment, provided the segment only touches copper at its end points.

Activation

When pp_sm_spacing = Yes, outer layers only.
