Well, obviously you use the right tools :-). Attacking
any
computer board
with a sheet-metal iron is going to do some damage. But
I don't
understand why a PC motherboard is any more fragile than (say)
a board
from a minicomputer, workstation, or whatever.
Well, for one thing old boards used .1 inch traces, now with
surface mount it's .05 or .025. I don;t know about you, but my
hand (wasted from advanced age and hard living) isn't steady
enough to solder a surface mount IC.

The trick is not to worry about bridging connections.
Solder the chip
down and then use desolder braid (solder wick) to clean off the excess
solder.
And don't forget a very fine tip for the iron... Or better yet, save up
for
a reflow station! I saw an ad in Nuts'n'Volts for one that was only
$1200... But first I think I'll get a nice Weller to replace my peice of
crap Radio Shack 15/30W switchable iron. I have my eye on one of those
<$100 variable power Wellers, I don't remember which model but there are
two of them. I think one sells for $99 and the other for around $50 or so.
And some of the desoldering braids would be nice, too. Those desoldering
bulbs are HORRIBLE. Those big vacuum ones are nice, and even more so for
the motorized vacuum pump models.

If you can find the *good* coaxial cable cheap, the braid on it makes great
solder wick. Especially the silver plated stuff.

True - and don't bother spending money on the no-name el cheapo brands.
Go straight for the brand names like "Solder Wick". The chemical coating
on the braid makes all the difference in the world!

I have two of the "hole-in-the-tip" irons, with tubing but no pump.
(Made by Pace, Inc. as I remember) anyone have a pump or ever
seen one available?

Yeah, I see them all the time at the hamfests. A complete one runs
around $100. I bought one without the iron but with the hand grinder for
$20. I bought a non working one with the iron for $10 a while back so now
I have a complete one with ALL the attachments and extra parts for $30.

Just pointing out a misplaced decimal point. IN CP/M days, the .1 inch
traces (and wider) would have been used for power distribution, and most of
the normal traces were in the .025" range. Currently, standard design
practice seems to be 8 - 10 mil lines although higher density boards can get
smaller tracewidths. I found the best way to deal with surface mount
components is under a microscope :).
