Purpose

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

 

Function

Reports circuit elements in the same layer that are closer than the action parameter pp_spacing , and are both exposed (not covered by solder mask) in the matching solder mask layer. Measurements are spacing segments, provided the segment only touches copper at its end points.

Activation

When pp_sm_spacing = Yes, outer layers only
