Obviously this only works with HASL plated boards but I have been fond of
doing the same thing for ENIG plated contacts by just tinning the tip of the
iron with solder (and I mean VERY little), fluxing the contacts and the just
touching each pin with the iron, works like a charm.  You should only have
enough solder on the tip for 3-4 pins but once you get it down, TQFP stuff
is no problem and you can even use that method for the dreaded uQFN stuff

That guy has steady hands. I'm not sure I could pull that off but it's
certainly interesting to know it can be done.
