A PCB designer added a ground plane but still experiences EMI issues. Which debugging step is most effective?
medium📝 Formula Fix Q14 of 15
Step-by-Step Solution
Solution:
Step 1: Verify grounding integrity
Proper grounding connections and stitching vias ensure the ground plane works effectively to reduce EMI.Step 2: Eliminate ineffective fixes
Removing capacitors or adding LEDs does not fix EMI; random trace width changes may worsen it.Final Answer:
Check for proper grounding connections and stitching vias -> Option AQuick Check:
Grounding integrity fixes EMI issues [OK]
Quick Trick: Verify grounding and stitching vias first [OK]
Common Mistakes:
MISTAKES- Removing capacitors thinking they cause EMI
- Adding unrelated components like LEDs
- Changing trace width without plan
