For a densely routed multi-layer PCB, which approach best ensures effective test point placement without compromising signal integrity?
AAdd test points randomly to all signal traces for maximum coverage
BPlace test points only on the top layer regardless of routing complexity
CIntegrate test points on accessible layers and use via-in-pad sparingly to maintain signal paths
DAvoid test points to reduce PCB complexity and rely on functional testing only
Step-by-Step Solution
Solution:

  1. Step 1: Understand constraints

    Dense routing and multi-layer PCBs limit test point accessibility and can affect signals.

  2. Step 2: Best practice

    Placing test points on accessible layers and careful use of via-in-pad preserves signal integrity.

  3. Final Answer:

    Integrate test points on accessible layers and use via-in-pad sparingly to maintain signal paths -> Option C

  4. Quick Check:

    Balance access and signal integrity [OK]
Quick Trick: Place test points strategically on accessible layers [OK]
Common Mistakes:
MISTAKES
  • Placing test points only on top layer
  • Randomly adding test points without planning
  • Skipping test points to reduce complexity
