PCB Design - Multi-Layer PCB DesignWhich of the following is the correct way to describe a 4-layer PCB stackup?APower Plane, Ground Plane, Top Signal, Bottom SignalBTop Signal, Power Plane, Ground Plane, Bottom SignalCGround Plane, Top Signal, Bottom Signal, Power PlaneDTop Signal, Ground Plane, Power Plane, Bottom SignalCheck Answer
Step-by-Step SolutionSolution:Step 1: Recall standard 4-layer stackup orderThe common order is signal layer on top, ground plane below it, power plane next, and signal layer at bottom.Step 2: Match options to standard stackupTop Signal, Ground Plane, Power Plane, Bottom Signal matches this order exactly.Final Answer:Top Signal, Ground Plane, Power Plane, Bottom Signal -> Option DQuick Check:Standard stackup = D [OK]Quick Trick: Ground plane is usually just below top signal layer [OK]Common Mistakes:MISTAKESMixing power and ground plane orderPlacing signal layers in the middleConfusing bottom and top layers
