PCB Design - Multi-Layer PCB DesignWhich of the following is the correct syntax to define a four-layer stack-up in a PCB design software layer stack file?ATopSignal; GroundPlane; PowerPlane; BottomSignalBTopSignal, PowerPlane, GroundPlane, BottomSignalCTopSignal GroundPlane PowerPlane BottomSignalDTopSignal|GroundPlane|PowerPlane|BottomSignalCheck Answer
Step-by-Step SolutionSolution:Step 1: Understand common layer stack syntaxMost PCB tools use semicolon-separated layer names for clarity and parsing.Step 2: Identify the correct separator and orderTopSignal; GroundPlane; PowerPlane; BottomSignal uses semicolons and correct layer order, matching typical syntax.Final Answer:TopSignal; GroundPlane; PowerPlane; BottomSignal -> Option AQuick Check:Correct syntax uses semicolons and proper order [OK]Quick Trick: Use semicolons to separate layers in stack-up files [OK]Common Mistakes:MISTAKESUsing commas or spaces instead of semicolonsMixing layer order incorrectlyUsing unsupported separators like pipes
