Working with the Layer Pairs Design Rule on a PCB in Altium Designer

Rule category: Manufacturing

Rule classification: Unary

Summary

This rule checks to ensure that the used drill-pairs match the currently defined drill-pairs. The used drill-pairs are determined from the vias and pads found in the board. The permissable drill-pairs are defined in the Drill-Pair Manager dialog.

Constraints

Default constraint for the Layer Pairs rule.

• Enforce layer pairs settings - specifies whether the check is made or not.

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 matches the object(s) being checked.

Rule Application

Online DRC, Batch DRC, and during interactive routing.
