Rule category: Manufacturing
Rule classification: Binary
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 that the distance between any two solder mask openings is equal to, or greater than, a user-specified minimum value. This includes the pads, vias, and any primitives that reside on solder mask layers. It also checks Top and Bottom sides independently.
Constraints
