Purpose |
A hole that is supposed to be isolated from power or ground planes must be kept apart from copper. The distance which is required is typically larger than regular spacing due to the higher than usual current. |
Function |
For drills that do not touch copper, reports the distance
from the edge of the drill to the nearest copper when less than the pp_d2c action parameter. |
Activation |
|
Known Limitations |
In Positive P&G layers no associated copper feature is
reported. |
This category may also be considered as the spacing of the hole
from the copper or its laminate annular ring; normally it shows how well holes
are embedded in laminate.
