12A is not extreme.

I was once discussing a 800A 12V PWM design
(yes, and worked and it had a 2kA cutoff function. I ended up doing it as an array of mosfets screwed on a coppper reail for bot power and cooling, and brass strips as both connections and curent sensing.)

It did not go into production, but the PCB manufacturer and I talked about diung multilayera board with parallel traces on most layers, selecting thivkest availavle copper, and use the plating technique to make them even thicker.
