During a design review, a PCB schematic shows a missing connection between two components. What is the likely outcome if this error is not caught before fabrication?
AThe PCB will function perfectly without issues.
BThe PCB will fail or behave unpredictably.
CThe fabrication cost will decrease.
DThe error will fix itself during manufacturing.
Step-by-Step Solution
Solution:
  1. Step 1: Understand impact of missing connection

    A missing connection means the circuit is incomplete and won't work properly.
  2. Step 2: Predict outcome if error is not fixed

    The PCB will fail or behave unpredictably, causing problems.
  3. Final Answer:

    The PCB will fail or behave unpredictably. -> Option B
  4. Quick Check:

    Missing connection = PCB failure [OK]
Quick Trick: Missing connection causes failure [OK]
Common Mistakes:
MISTAKES
  • Assuming PCB works fine without all connections
  • Thinking fabrication cost decreases due to errors
  • Believing errors fix themselves automatically
