I'm designing a PCB in which the current of a BLDC motor is measured through a PSG4NTEBL500F shunt resistor. The DC supply of the motor is connected to the PCB through a 12AWG cable and the circuit should handle current up to 50 A.
How can I connect the 12AWG cable to the PCB? I've thought of soldering it directly to a hole, is this approach appropriate for such high current?
How should I connect the wire to the resistor? My copper weight must be 1 oz, so a simple trace would have to have an insanely high width. The resistor will be the only component on the bottom of the PCB.
