Policy on hole size / slots /  cutouts Available Drill & Router bit diameter
  • Specified hole size will the final hole size (+/- 1 mil)

  • Specified slot size will be the final slot (+/- 1 mil)

  • 60 mil routing tool would be used for internal cutouts.

  • 12 mils to 149 mils - 1 mil increment
  • 150 mils to 250 mils - 4 mil increment
  • Holes larger than 250 mils will be routed.
  • Smallest router diameter - 31 mils
