Purpose |
The area in and around a plated through hole should be clear of mask, enabling the solder wave to completely fill the hole around the component pin. |
Function |
Reports distances less than pp_ar between PTHs and solder mask in negative layers. Measurements are segments corresponding to the minimal distance between drill and clearance outline. |
