Why does a thorough design review reduce the risk of costly PCB fabrication errors?

easy🧠 Conceptual Q10 of 15
PCB Design - Design Review and Testing
Why does a thorough design review reduce the risk of costly PCB fabrication errors?
ABecause it identifies and fixes errors before manufacturing
BBecause it speeds up the soldering process
CBecause it reduces the number of components needed
DBecause it improves the packaging design
Step-by-Step Solution
Solution:

  1. Step 1: Understand the impact of design review

    Design review finds errors early, preventing costly mistakes.

  2. Step 2: Eliminate unrelated benefits

    Soldering speed, component count, and packaging do not directly reduce fabrication errors.

  3. Final Answer:

    Because it identifies and fixes errors before manufacturing -> Option A

  4. Quick Check:

    Early error fixing reduces fabrication risk [OK]
Quick Trick: Fix errors early to avoid expensive rework [OK]
Common Mistakes:
MISTAKES
  • Confusing design review with assembly or packaging
  • Thinking design review changes component count
  • Assuming it speeds soldering
