Purpose	A pad and a circuit too close may bridge during imaging, etching, plating or soldering, and result in a direct short.
Function	Reports unconnected pads and circuit elements closer than pp_spacing in the same layer. Measurements are segments, provided they only touch copper at its end points. Does not report measurements involving features with attribute Copper Feature Ignore. If the job was created directly from a CAD database, extra functionality is provided. A measurement between pads, even if unconnected, and circuits of the same CAD net in the same layer are placed in the ‘CAD Self Spacing’ category rather than in the ‘Pad to Circuit’ category.
