Summary

This rule helps identify narrow sections of solder mask that may cause manufacturing problems at a later stage. Ensuring that there is a minimum width of solder mask across the board, this rule checks the distance between any two solder mask openings to ensure that they are equal to or greater than the user-specified value. This includes the pads, vias, and any primitives that reside on solder mask layers. It also checks Top and Bottom sides independently.
