It's not really a problem.
I've hand soldered 0.4mm pitch LQFPs on a home made board without solder
resist. (Making the board with that fine pitch was a far bigger trial
than soldering the chip to it). Solder wick and flux are your best friends.
After many detours using solder paste, stencils, hot air etc. I've come
to the conclusion that I can solder SMD faster and more neatly with a
soldering iron. I've found using some kapton tape to hold the part in
position, and use plenty of flux from a flux dispensing pen before
soldering gives very good results and it's easy to do, since getting the
part positioned by taping it down is easier than trying to tack corners
on any of the packages with pins on all 4 sides.
