Function |
Reports for NPTHs embedded in copper the distance to the
nearest laminate that is less than the
pp_d2c action parameter. If
limited_npth_check is set to No , all annular rings in the vicinity are
reported. If set to Yes , the maximum distance reported is
that defined by pp_d2c
. Measurements are distance segments between the NPTH and
nearest laminate. |
Activation |
|
Known Limitations |
The action tries to identify the pad that is associated
with the NPTH and add its ID to the measurement. If it cannot (e.g. NPTH
drilled thru drawn features), it inserts an r0 instead. If there is any copper in the NPTH, then a zero annular
ring measurement will be reported. This may be considered by some to be a
false alarm. |
