The Drill-Pair Properties dialog.
Summary
This dialog allows the designer to configure a drill pair for the active layer stack, in terms of start and stop layers. Drill pairs must be configured when blind, buried, or build-up type vias are to be used, with a drill pair for each layer-pair that a via spans.
Access
The dialog is accessed from the PCB Editor, through the Drill-Pair Manager dialog, in the following ways:
- Clicking the Add button.
- Selecting a currently defined drill pair (other than the Top Layer - Bottom Layer drill pair, when the active stack is the default Board Layer Stack, which cannot be edited) and clicking the Drill Pair Properties button.
Options/Controls
- Drill-Pair Properties - the following fields collectively define the drill pair:
- Start Layer - the start layer for the pair. Choose from any of the currently defined signal and plane layers for the board, as configured and enabled in the active layer stackup.
- Stop Layer - the stop layer for the pair. Choose from any of the currently defined signal and plane layers for the board, as configured and enabled in the active layer stackup.
Tips
- Drill pairs must be defined to suit the layer stack-up style. This should be done in consultation with your board manufacturer to ensure that your design matches their fabrication technology.
