I do surface mount work ALL DAY, and I was dubious at first, but now that I
see how cheap it can be as far as pcb costs (no drilling) and component cost
(dont have to pay to have leads fused on) and how much can be put into a
small package, I am ALL FOR IT.. The reliability of smd simply rules, and
the heat dissipation of smd packages is far better if heat pads are used to
relieve some of the heat to the pcb itself..
I too, say, to everyone "get with SMD, or prepare to find it harder and
harder to come by components..

BTW, I have soldered 28 to 64 lead plcc packages with a first run ratio of
about 99%...

As for placement of parts, its all in your breathing.. I use a breathing
control technique that snipers use to steady their hand.. Sure, its kind of
a pain, but when you see an entire ladder filter in about 1 sqr inch, it
makes you wonder why you have waited so long to learn it.. But, with SMD,
flux is a neccesity or you will solder web all you legs together...

If anyone needs any SMD tips, let me know.. I have encountered some of the
worst SMD problems anyone could run across, everything from removing 68 pin
j-leg processors to trying to get those gnat sized resistors to sit still
while you solder them..

I say, lets all go surface mount asap.. You just need a good solder iron and
controlled breathing..

Oh, and try not to sneeze ;))
