Drills Touching Copper Count is a DFM action which counts the number of times each drilled hole touches copper in the copper layers through which it passes. When run using the default parameters, the report produced by the DFM action is of particular interest to planning engineers. The report can help planners determine the process to use to drill the board and to estimate the usage of drill bits.
The DFM action also enables different handling of drill holes according to the number of times the drilled hole will touch copper. This can be done using one of two methods:
enables the separation of drills in the Auto Drill Manager table according to the number of times the drill hole touches copper.
The drill layer can be split into two or more layers according to the number of times the drill holes touch copper. This allows the operator the freedom to handle these layers as separate entities.
