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.

All design rules are created and managed within the PCB Rules and Constraints Editor dialog. For a high-level view of working with the design rules system, see Defining, Scoping & Managing PCB Design Rules.

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 expressions match the object(s) being checked.

Rule Application

Online DRC and Batch DRC.
