For the motor drive design of PWM speed regulation, what points should be paid attention to when changing the PCB? Can you give some suggestions in terms of functions and sexual energy? Such as the output current and voltage range, the influence of the control input, the influence on the power supply and the reliability.

Pay attention to the temperature rise of the board and the characteristic parameters of MOS

I think we can try to open the window with solder mask, and then apply solder to increase the overcurrent capability

You can re-soldering or copper foil welding from the area that needs high current to the interface, so that the pcb can work normally under the high current state.
