Where to Apply It As per the image below, you would apply your mechanical hole spacing constraints in the Design > Copper Spacing worksheet. Select the rule in the dropdown option, and you will see that they are applied (expand the Holes row if they are not visible). Downstream Impact: Fewer short circuits to your mounting chassis, cables, etc. Fewer concerns during testing. Acid Traps: Avoiding Acute Angles in Copper Features That Can Trap Etching Chemicals Purpose: While many manufacturers have updated their processes to avoid acid traps regardless of copper angles, some manufacturers can still have this problem. You can use the constraint manager to check for unintended acid traps. Potential spacing issues that can commonly create acid traps 33 www.cadence.com OrCAD X Constraint Management Guide
