Leon,
 A method I use to solder these packages is to use your finest tip,
then take a small piece of wire, cut it at an angle so the tip is
sharp, then use that as a wedge to get the solder to bridge the pin to
 the pad.

 Also, bring the pads out from under the part a few mills further than
suggested, then move them back to go into production.

 The most succesfull, process I have used is a stencil, and solder
paste, then just heat the part from the top (hot air gun), when it
flows, let it cool, then use the afore mentioned method to remove any
bridges, or make unsuccesfull connections.
