PCB Design - Manufacturing Output
You need to generate a drill file for a PCB with two hole sizes: 0.5 mm and 1.2 mm. The holes are at positions (5,10), (15,20) for 0.5 mm, and (10,15) for 1.2 mm. Which drill file snippet correctly represents this?
Which drill file snippet correctly represents this?
hard📝 Scenario Q15 of 15
Step-by-Step Solution
Solution:
Step 1: Confirm tool and diameter format
Tool lines must use 'TxxCyy' format, e.g., T01C0.5 for tool 1 with 0.5 mm diameter.Step 2: Convert coordinates to drill file units
Coordinates are in thousandths of mm, so (5,10) becomes X5000Y10000, etc.Step 3: Check all lines for correctness
T01C0.5\nX5000Y10000\nX15000Y20000\nT02C1.2\nX10000Y15000uses correct tool format and coordinate scaling; others have wrong formats or units.Final Answer:
T01C0.5 X5000Y10000 X15000Y20000 T02C1.2 X10000Y15000 -> Option AQuick Check:
Tool format + coordinates in thousandths mm =T01C0.5\nX5000Y10000\nX15000Y20000\nT02C1.2\nX10000Y15000[OK]
Quick Trick: Multiply mm by 1000 and use TxxCyy format [OK]
Common Mistakes:
MISTAKES- Using mm directly without scaling
- Incorrect tool number format (missing leading zero)
- Mixing decimal and integer coordinate formats
