What is the primary signal integrity concern when a high-speed PCB trace includes multiple sharp 90-degree bends?
What is the primary signal integrity concern when a high-speed PCB trace includes multiple sharp 90-degree bends?
medium📝 Formula Fix Q6 of 15
Step-by-Step Solution
Solution:
Step 1: Understand trace geometry effects
Sharp 90-degree bends cause abrupt changes in trace geometry, leading to impedance discontinuities.Step 2: Identify impact on signals
These discontinuities cause signal reflections, degrading signal integrity.Final Answer:
Increased signal reflections due to impedance discontinuities -> Option AQuick Check:
Sharp corners cause reflections [OK]
Quick Trick: Sharp 90° bends cause reflections, avoid them [OK]
Common Mistakes:
MISTAKES- Assuming 90-degree bends reduce crosstalk
- Believing sharp bends improve attenuation
- Thinking sharp bends enhance shielding
