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 may be 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. Vias that are drilled in smt lands may be
intentionally offset. |
