Soldering iron set to 340°C. IC fixed in place with solder on one pin, then drag soldered the pins on both sides. Might work with lower temperature.
Should’ve taped off the holes during soldering.
Using the affordable Yihua 937D soldering iron, with a nice Plato HS-2752 soldering tip. MG Chemicals 836-P flux pen, and AIM 13236 soldering wire.
