Current concerns when soldering
High current traces must be. Wide and Short . Use Saturn’s free PCB executable tool to calculate the voltage drop per mm length for a given track width and copper weight with solder plating thickness. If excessive you may need to reinforce with short 16-24AWG wire soldered to tracks for power , ground return and drive signals.  Keep loop area of all current loops to a practical minimum by every means due to switched inductive loads.
