I know that LMZ31704 has bottom pad, VOUT(41 pin) and PH (42 pin). Now I plan to replace it on EVM because it was damaged, but then the solder machine can't solder bottom pad. I understand that the thermal performance will be decreased if the bottom pads are not soldered, but I believe that it will be no problem electrically. Is my understanding correct? I also know that 10 pin (PH) is connected to bootstrap diode internally, so it must be connected other PH pin on PCB.
