Rule Classification: Binary

Summary

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

To summarize, this rule:

Checks that the distance between any 2 solder mask openings is greater then the user specified value;
Checks only pad, vias & any primitives that reside on solder mask layers;
Checks Top / Bottom sides independently

Constraints

Default constraints for the Minimum Solder Mask Sliver rule.

Minimum Solder Mask Sliver - minimum allowed width of solder mask.

How Duplicate Rule Contentions are Resolved

All rules are resolved by the priority setting. The system goes through the rules from highest to lowest priority and picks the first one whose scope expression(s) match the object(s) being checked.
