This category may be used to classify the Pad annular ring measurement according to the four pad types: PTH Pads, NPTH Pads, Via Pads and Non-Drilled Pads. Activate this option by setting the ERF variable classify_pad_ar to 1. Note that all annular ring categories do not report anything if a pad (or drill) is completely covered by solder mask. Zero annular ring may be reported if a solder mask clearance and a pad drill overlap but neither one includes the other.
Function |
Reports undrilled pad to solder mask distances less than
the pp_ar action
parameter. Such a feature could be Measurements are distance segments corresponding to the minimal distance between the pad and the clearance outline. |
Activation |
When the ERF variable classify_pad_ar is set to 1 |
Known Limitations |
If the clearance is drawn, or if the clearance precisely covers the outer layer pad (1:1), the clearance ID will be r0. |
