I took some PCI cards out of my computer and placed them onto the carpet.
Could there be any static electricity that might damage them if they're
sitting on the carpet?
There could be, but there probably isn't. Just don't do anything like
that again, ever.
The next time you need to set down a computer card, memory module, or
anything else with exposed chips, do it on anti-static material, such
as the foam sheet included with motherboard packaging or pink bubble
wrap or, if you have absolutely nothing else available, aluminum foil.
However don't use aluminum foil for motherboards or anything else
containing a battery (battery will short against the foil and possibly
explode), and with foil you must take care to touch it with your hand
just before laying the card or module against it since it can allow
high current to flow and damage chips. Do not use ordinary foam sheet
or bubble wrap, neither of which are treated to be anti-static and
actually hold high, damaging static charge. In addition to these
precautions, other important ones are: 1) frequently touch the
computer chassis to discharge yourself before handling chips; 2) keep
the room humidity level above 20-30%; and 3) work completely barefoot.
