PCB Design - Advanced Routing Techniques
In a design with parallel buses, if the PCB material changes to one with a higher dielectric constant, how does this affect length matching?
In a design with parallel buses, if the PCB material changes to one with a higher dielectric constant, how does this affect length matching?
hard📝 Scenario Q9 of 15
Step-by-Step Solution
Solution:
Step 1: Understand effect of dielectric constant
Higher dielectric constant slows signal speed on traces.Step 2: Impact on length matching
Since signal speed changes, physical length must be adjusted to maintain timing.Final Answer:
Signal speed changes, so length matching must be recalculated -> Option AQuick Check:
Material affects signal speed and length matching [OK]
Quick Trick: Material changes require length recalculation [OK]
Common Mistakes:
MISTAKES- Ignoring material effect on signal speed
- Assuming length matching is fixed
- Thinking width adjustments fix timing
