PCB Design - Multi-Layer PCB Design
Which of the following is the correct way to describe a multi-layer PCB structure?
AOnly one layer for signals and one for power.
BA single copper layer with no insulation.
CCopper layers stacked without any insulation.
DMultiple copper layers separated by insulating material.
Step-by-Step Solution
Solution:

  1. Step 1: Identify PCB layer composition

    Multi-layer PCBs have several copper layers separated by insulating layers to prevent shorts.

  2. Step 2: Confirm correct description

    Multiple copper layers separated by insulating material. correctly states multiple copper layers separated by insulation.

  3. Final Answer:

    Multiple copper layers separated by insulating material. -> Option D

  4. Quick Check:

    Insulation separates copper layers [OK]
Quick Trick: Remember: layers need insulation to avoid short circuits [OK]
Common Mistakes:
MISTAKES
  • Ignoring insulation between layers
  • Thinking copper layers touch directly
  • Confusing single-layer with multi-layer structure
