I'm design a PCB with low voltage (1.0V) high current (up to 50A) power supply for a single chip. But I'm not sure about the thickness of copper for the power plane. How do I calculate this parameter? Is 1oz enough for it? I saw gigabyte has been using 2oz on its motherboards, but I guess the highest current on a motherboard is much higher than 50A?
