I normally tack one pin down. It doesn't need to be a particularly good
solder joint, just something that will hold it in place.
I like to paint some no-clean liquid flux over all of the pads. If you let it
dry a bit, the flux gets a bit tacky and helps to hold the part in place.
I usually put a little bubble of solder on one of the "corner" pads, position
the pin over the pad and heat it until the solder melts. Then I'll fine tune
the position, using my tweezers tnd the soldering iron until I'm happy, tack
down the opposite corner, and then properly solder all of the pins, going
back and revisiting the first two pins that were just tacked down.
