Subject: Chlorine damage to electronics

Hi there.  This is additional information for the voicemail
message I left you earlier this morning.  Can you help me
get this question to the right person?  I would greatly 
appreciate it.

We've got a situation where electronic circuit boards were
exposed to dry chlorine gas for several hours.  Many of
the IC chips have failed, but other than a few exposed ends
of copper wire turning brown, there is no visible evidence
of corrosion on the boards.  I know that there would likely
have been significant evidence if the ambient humidity had
been higher, due to formation of hydrochloric acid.

Can chlorine gas molecules penetrate the plastic IC housings
and attack the tiny, gold connecting wires inside the chips?
Or is there some other explanation?

Thanks very much!
