Parent page: PCB Query Functions - Fields
Summary
Returns all polygon pour objects whose Neck Width Threshold property complies with the Query.
Syntax
PolygonNeckWidthThreshold : Number
Number will follow the measurement units currently employed for the document – either Imperial (mil; 1mil = 0.001inch) or Metric (mm; 1mm = 0.001meter).
A specific option for the measurement unit can be specified – overriding the default units specified at the document level – through use of an additional measurement unit-based keyword:
AsMils(PolygonNeckWidthThreshold) : Number– to specify a threshold in mil.AsMM(PolygonNeckWidthThreshold) : Number– to specify a threshold in mm.
Example Usage
PolygonNeckWidthThreshold = 5
Returns all polygon pour objects that have an Neck Width Threshold property which is 5 current measurement units.
PolygonNeckWidthThreshold >= 5
Returns all polygon pour objects that have an Neck Width Threshold property which is greater than, or equal to, 5 current measurement units.
AsMils(PolygonNeckWidthThreshold) Between 5 And 10
Returns all polygon pour objects that have an Neck Width Threshold property which is greater than, or equal to, 5mil and less than, or equal to, 10mil.
AsMM(PolygonNeckWidthThreshold) < 0.127
Returns all polygon pour objects that have an Neck Width Threshold property which is less than 0.127mm.
Tips
- The Neck Width Threshold property is only defined for polygon pour objects.
- The child objects of polygon pour objects returned by the Query, are not returned.
