Purpose

Silk screen should never be applied on holes since it will be unreadable and adversely affect the assembly process.

Function

Reports close distances between silk screen features and PTHs that are less than the pp_spacing action parameter.

Activation

If the ERF variable v_check_only_exposed_drill = yes, it will report Spacing problems only against PTH drill holes that are exposed in the SM layer, means covered by SM Clearance.

If the ERF variable v_report_include_as_zero = yes, the measurement will become a point on the PTH hole.
