Which factor is most important when deciding the spacing of vias in a stitched ground plane?
Which factor is most important when deciding the spacing of vias in a stitched ground plane?
easy🧠 Conceptual Q2 of 15
Step-by-Step Solution
Solution:
Step 1: Consider what affects ground plane performance
High-frequency signals require better grounding to reduce noise and interference.Step 2: Understand via spacing impact
Closer via spacing reduces impedance and improves grounding for high-frequency signals.Final Answer:
The frequency of the signals on the board -> Option BQuick Check:
Via spacing depends on signal frequency [OK]
Quick Trick: Signal frequency guides via spacing in ground planes [OK]
Common Mistakes:
MISTAKES- Ignoring signal frequency importance
- Focusing on PCB color or thickness instead
- Assuming number of signal layers controls via spacing
