Why does the via stitching pattern fail if vias are placed too close together on a PCB?
Why does the via stitching pattern fail if vias are placed too close together on a PCB?
medium📝 Formula Fix Q7 of 15
Step-by-Step Solution
Solution:
Step 1: Understand effects of dense via placement
Too many vias close together increase drilling and plating costs and can cause heat buildup.Step 2: Check for electrical issues
Close vias do not cause shorts if properly designed; color and signal layers are unrelated.Final Answer:
It increases manufacturing cost and may cause thermal issues -> Option BQuick Check:
Dense vias raise cost and heat [OK]
Quick Trick: Balance via density to control cost and heat [OK]
Common Mistakes:
MISTAKES- Assuming close vias cause shorts
- Confusing via density with signal layers
- Ignoring manufacturing constraints
