    Figure 1.
    • Item: Specify the item name.
    • Scan Range: Set target hole size value ranges.
    • Base Value: Among the holes that have sizes in the scan range, PollEx DFM checks the size of the hole and if their values are not matching with the base value, they will be detected as fails.
  • Check the difference between the smallest and largest Via hole diameter : Check the difference between the largest via hole and the smallest via hole among vias used in PCB design.
    • Scan range of Via hole diameter : Designates the range of via hole size to be checked, if the option is not selected, all vias in the PCB design are subject to checking
    • Maximum Via hole diameter difference : specifies the diameter difference between the maximum allowable via hole and the minimum via hole diameter.
