PCB Design - Manufacturing Output
Given the drill file snippet:
T02C1.2
X05000Y10000
X07000Y12000

What does this snippet specify?
AUse tool 2 with 1.2 mm diameter to drill holes at (50,100) and (70,120)
BUse tool 2 with 1.2 mm diameter to drill holes at (5,10) and (7,12)
CUse tool 1 with 2 mm diameter to drill holes at (5,10) and (7,12)
DUse tool 2 with 12 mm diameter to drill holes at (5000,10000) and (7000,12000)
Step-by-Step Solution
Solution:
  1. Step 1: Interpret tool and diameter

    'T02C1.2' means tool number 2 with 1.2 mm diameter.
  2. Step 2: Understand coordinate units

    Coordinates 'X05000Y10000' represent 5.000 and 10.000 mm (units usually in thousandths of mm).
  3. Final Answer:

    Use tool 2 with 1.2 mm diameter to drill holes at (5,10) and (7,12) -> Option B
  4. Quick Check:

    Coordinates scaled to mm = (5,10) [OK]
Quick Trick: Coordinates often scaled; 05000 means 5.000 mm [OK]
Common Mistakes:
MISTAKES
  • Misreading coordinates as 50 or 5000 mm
  • Confusing tool number or diameter
  • Ignoring scale of coordinates
