IIGS MOTHERBOARD: Which components are heat-sensitive?

[buggie@indus.unm.edu (stephen e buggie)]

Now that I've learned improved desoldering techniques, I plan to remove
the reusable components from two dead IIgs motherboards I have cluttering
up the place.

But which components on the GS motherboard are most sensitive to heat?
What about the Ensoniq sound chip?

Has anyone ever attempted desoldering of surface-mount components such as
the IIe mega-chip on the IIgs motherboard?  I subscribe to the magazine,
SURFACE MOUNT TECHNOLOGY, but they have never yet had an article on
hobbiest desoldering!  I'd like to be able to remove a SMT component, the
IWM chip drive-controller.

Someone contacted me in reply to my previous post ---- asking if I could
replace the standard RAM with fast RAM.  Yes, but its not recommended ----
too risky.

My desoldering skills have improved, but are not perfect.  The level I am
at is to desolder components from dead boards, or to attempt to fix a dead
board.   I'd be _reluctant_ to desolder/hack a perfectly working board!
