PCB Design - Design Review and Testing
Which factor is most important when deciding where to place test points on a PCB?
AProximity to components that need testing
BColor of the PCB solder mask
CNumber of layers in the PCB
DType of solder used
Step-by-Step Solution
Solution:
  1. Step 1: Identify what test points connect to

    Test points must be near components or nets that require testing.
  2. Step 2: Evaluate other options

    PCB color, layers, or solder type do not directly affect test point placement.
  3. Final Answer:

    Proximity to components that need testing -> Option A
  4. Quick Check:

    Key placement factor = Proximity to test targets [OK]
Quick Trick: Place test points close to components needing tests [OK]
Common Mistakes:
MISTAKES
  • Choosing placement based on PCB color
  • Ignoring component locations
  • Focusing on solder type instead of test access
