Altium Designer : PCB Planes Pullback implementation

There are many ways to implement polygon plane pullback in Altium. One of my preferred ways is utilizing design rules as below.


Alternatively,  a keep-out layer to define polygon pullback can be used.


If you believe in 20H rules to implement for Internal plane pullback, Layer Stack Manager can be used for internal planes.







Hot-Swap Circuits with Inrush Current Limiter

  To provide continuous current sensing and limiting, this hot-swap circuit uses a PNP transistor and a current sense resistor of 0.333R. Wh...
