  • [Solved] Return Current Path For USB Lines

    Hello Guys,
    I'm Designing my first 4 Layer PCB and had a issue with return current path of my USB lines on Bottom Layer.
    my stack-up is like this:

    TOP Signal
    Prepreg---------0.1mm
    GND
    Core-------------1.265mm
    Power
    Pregreg---------0.1mm
    BOT Signal

    So I cut the Power Plane and draw a GND polygon under USB and other signals.
    Is this a right thing to do or I better stitch power and GND with 100nf caps near every Via?

    Thank you for your time.
