Board-Drill

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.

Description

.drill

This attribute is attached to hole features in drill layers. It defines the type of the drill and is used extensively during fabrication analysis.
