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.
