Sorry, I forgot to mention.

We don't add solder paste for soldering those fine pitched jobbies, the solder being little balls (check with a microscope) cause shorts between the pins and you'll have to rework under a microscope. The PCB's we get come with the pads soldered (tinned) and is then cleaned with a hot air knife, so a tiny amount of solder is still left on each pad. To solder these use only flux on the footprint, be aware if you handle the chips by hand and the pins gets bent it's back to the microscope yet again.
