  • [Solved] pcb stackup question

    Hi
    In Learning Altium essential ed2 there is a 6 layer pcb stackup.
    I haven't understood with what logic the nets were divided on the various layers.
    Are layer 2 and 5 without nets? They are called planes while the other layers are called signal.
    If they are empty why are they present?
    Thanks

    Layers 2 and 5 are used as solid GND planes. Then, L4 will be used for Power and L3 will be used for noisy signals, feedback and a few more. It will be explained.
