Pad-Free Mounting Holes for OrCAD PCB / Allegro Printed From: PCB Libraries Forum Category: PCB Footprint Expert Forum Name: Product Suggestions Forum Description: request new features URL: https://www.PCBLibraries.com/forum/forum_posts.asp?TID=1177 Printed Date: 25 Nov 2024 at 12:30am Topic: Pad-Free Mounting Holes for OrCAD PCB / Allegro Posted By: kwgilpin Subject: Pad-Free Mounting Holes for OrCAD PCB / Allegro Date Posted: 17 Nov 2013 at 12:27pm When FPX creates a non-plated mounting hole (e.g. for a custom FP Designer component), it includes a pad that is sized smaller than the drill.  Cadence Pad Designer does not really like this and generates a warning.  Additionally, I have had at least one board house complain about this as well.  The better approach would be to use the "Mech pins use antipads as Route Keepout: ARK" option within Pad Designer.  When that checkbox is enabled, the copper pads can be set to a size of 0.0 while the thermal relief and anti-pad are define the route keepout area around the hole. Can you make the necessary change to the translator?
