Board-Drill is a read-only action intended to find potential manufacturability defects in drill and compensated rout layers. It generates measurements between drills and/or compensated rout paths piercing the same circuit layer. Measurements are made between drills and other drills, drills to rout features, but not between rout to rout features. The Board-Drill action extends the functions available in the Drill Checks action.
The system uses a dynamic algorithm that adapts to user-selection and provides maximum performance. It assumes that all features on a rout layer are rout features even though some features may have non-rout attributes. However, with drill layers, feature attributes are considered and will be treated accordingly.
· The rout paths used in this section are compensated rout paths.
·
Measurements are made from edge of hole to edge of compensated
rout feature. A measurement is made between drills and routs that pierce the
same circuit layer.
A summary of the Feature attribute used during the Board-Drill check is shown below:
