Purpose: Defines the minimum distance between the edge of a drilled hole and the nearest copper feature to prevent manufacturing issues and ensure manufacturing reliability by preventing short circuits. May even require X-ray analysis through the PCB to adjust for scaling of PCB size and layers. Steps: 1. Open the Constraint Manager. 2. As shown above, navigate to the Manufacturing Constraints section > Design for Fabrication > DFF Constraint Set > Copper Spacing spreadsheet. 3. Look for a setting called All pin pads to > Trace. 4. Add a new Fabrication Constraint Set by clicking on the New CSET column. 5. You get the Create DFFCopperSpacingCSet window. 6. With the options above (CSet Usage = Etch), click Ok. 29 www.cadence.com OrCAD X Constraint Management Guide
