Quite easy if you use the 'drag-soldering' technique - tack down two 
opposite corners, apply plenty of flux, put a small amount of solder on the 
soldering iron tip and wipe the tip along the pins and remove any shorts 
with desolder braid. It can be done with an ordinary soldering iron but a 
Metcal like the one I use has a special tip:
