I do it.  I tin a couple of side by side pads.  Then I place the chip so th=
at the pins line up with the pads (the hardest part of it).  Then I touch t=
he pins over the tinned pads to tack the chip down.  Then I go to another r=
ow of pins and blob solder down the row of pins.  I do this for all sides. =
 Then I get de-soldering braid and suck up the excess.  This sounds terribl=
e but works great.  I very rarely end up with a pin not soldered or a short=
..  I have to admit I was nervous the first time I tried it but it's standar=
d practice for me now.
