Dan and all,

I would not "lay down a small puddle of solder" on more than one
pad. That puddle of solder on the diagonal lead can keep the other
IC leads from seating firmly onto the board traces. Limit the
"small puddle of solder" to one lead only. Once that lead is
soldered in place, then go to the diagonally opposite pin and solder
Then there is the "flood with solder, then remove the excess with
solder wick" - that method does work well in many cases. Check
carefully with magnification to assure that no solder bridges are
present if you use that method.

As complicated as SMD soldering is I find it very
cathartic. It requires so much concentration that you
HAVE to shut everything else out and except on the
teeny-tiniest ones it's just a matter of working through
I use the
"puddle" method. I lay down a little puddle of solder on
one pad (two diagonally opposite pads for an IC). Then I
maneuver the part into position and apply heat to 'sink'
the part into the puddle. You can actually build up a
rhythm doing it that way. I can even line up several
parts in a row and nail them down without jiggling the
others out of position. Someone told me about the bamboo
tweezers. I heard that the BEST 20 & 21 tweezers
were good and being wooden they are not magnetic,
conductive and are static free. They hold firmly but
hardly ever 'shoot' the parts out. And they're cheeeep
on that watery auction site.
The only problem
I've discovered with this particular board set is that
the copper must be low weight. It lifts very easily
(found that on the board I ruined). So you have to be
very careful with solder wick or you'll tear a pad off.
That plus they're small pads!
