Hi I have a question.If we have stacking sequence given below.Return path can be VCC plane (provided it's not broken) or Gnd plane. TOP GND1 LAYER3 LAYER4 VCC LAYER6 GND2 BOT If Layer 3 takes GND1 as return path, What will be return path for Layer 4 & Layer 6. Why? Can anyone explain the theory / mechanism.
