Drill Summary is a read-only action intended to generate
statistics on holes in padstacks. It finds the minimum annular ring in a
padstack and generates a table listing all the annular rings in the padstack
for a specific hole.
Measurements are from edge of hole to other net copper
encompassing copper or SM clearance.
The Drill Summary action uses dynamic category names to report
annular rings and hole dimensions.
The general structure of a category name is as follows:
layer_name |
outer |
PTH |
DIAM |
AR |
The following figure shows a sample output:
A summary of Feature and Component attributes used during the
Drill Summary is shown below:
Attribute Name |
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. |
The following is a sample textual report:
An attribute is assigned to each layer and each dynamic category.
Each dynamic category corresponds to a result attribute (as in the table
below). Each attribute represents a minimum value for the dynamic category.
