Which of the following is the correct way to describe a controlled impedance trace in PCB design?
Which of the following is the correct way to describe a controlled impedance trace in PCB design?
easy🧠 Conceptual Q12 of 15
Step-by-Step Solution
Solution:
Step 1: Define controlled impedance
Controlled impedance means the trace width and spacing are designed to keep impedance steady.Step 2: Identify correct description
The correct description is of a trace designed with specific width and spacing to maintain constant impedance.Final Answer:
A trace designed with specific width and spacing to maintain constant impedance -> Option BQuick Check:
Controlled impedance = specific width and spacing [OK]
Quick Trick: Controlled impedance means fixed width and spacing [OK]
Common Mistakes:
MISTAKES- Assuming random width controls impedance
- Thinking thickness alone controls impedance
- Believing layer choice controls impedance
