Purpose

Typically, a hole should be right in the middle of a pad.

Any deviation may indicate inaccuracy in the input files or a CAD system error.

Function

Reports the smallest center-to-center distance between drills and touching pads, if this distance is larger than the reg_allowance ERF variable and smaller than the max_reg ERF variable. Measurements are segments representing distance.

Activation

 

Known Limitations

Because of the max_reg filter, large registration errors are considered to be intentionally offset, and therefore missed. In such cases there is misregistration between the drill and the pad associated with it. If the distance between the centers is larger than the ERF variable max_reg, then the features are considered to be offset on purpose.
