What does a drill file specify in PCB design?
✗ Incorrect
A drill file specifies the sizes and locations of holes to be drilled on the PCB.
Which file format is most commonly used for drill files?
✗ Incorrect
Excellon format is the standard for drill files in PCB manufacturing.
What could happen if the drill file has incorrect hole coordinates?
✗ Incorrect
Incorrect hole coordinates cause holes to be drilled in wrong places.
Which of these is NOT typically included in a drill file?
✗ Incorrect
Component values are not part of drill files; they are in the BOM or schematic.
Why must drill files be carefully checked before manufacturing?
✗ Incorrect
Careful checking prevents errors in hole placement and size that affect PCB assembly.
