Step-by-Step Solution
Solution:
Step 1: Analyze the layer order
The ground and power layers are placed between signal layers, creating shielding and reducing interference.Step 2: Understand the effect on signal quality
This arrangement reduces electromagnetic interference and improves signal integrity by isolating signals with power and ground planes.Final Answer:
It reduces electromagnetic interference by placing ground and power layers between signal layers -> Option AQuick Check:
Ground/power between signals reduces interference = D [OK]
Quick Trick: Ground and power layers between signals reduce interference [OK]
Common Mistakes:
MISTAKES- Thinking it increases thickness unnecessarily
- Assuming it complicates routing
- Believing it reduces vias
