Which of the following is the correct way to describe a serpentine trace used for length matching?

Serpentine trace =

AA straight trace with no bends
BA trace with extra loops to increase length
CA trace that reduces signal speed
DA trace that connects different layers
Step-by-Step Solution
Solution:
  1. Step 1: Define serpentine trace

    Serpentine traces add loops or bends to increase trace length.
  2. Step 2: Compare options

    The description "a trace with extra loops to increase length" correctly defines a serpentine trace.
  3. Final Answer:

    A trace with extra loops to increase length -> Option B
  4. Quick Check:

    Serpentine = loops to increase length [OK]
Quick Trick: Serpentine means looping trace to add length [OK]
Common Mistakes:
MISTAKES
  • Thinking serpentine traces are straight
  • Believing serpentine reduces signal speed
  • Confusing serpentine with layer transitions
