Which technique is typically applied to increase the length of a shorter PCB trace to match longer parallel traces?

AUsing a different PCB substrate material
BIncreasing the trace width
CAdding serpentine or meander patterns
DReducing the signal frequency
Step-by-Step Solution
Solution:
  1. Step 1: Identify length adjustment methods

    Trace width changes or substrate changes do not affect length.
  2. Step 2: Use serpentine patterns

    Serpentine (meander) patterns add physical length without changing layout area significantly.
  3. Final Answer:

    Adding serpentine or meander patterns -> Option C
  4. Quick Check:

    Serpentine patterns increase trace length [OK]
Quick Trick: Serpentine patterns add length without changing width [OK]
Common Mistakes:
MISTAKES
  • Confusing trace width with length
  • Thinking substrate affects trace length directly
