I'm sure there's someone out there with Bellcore "listening". How do we get this paper?? ______________________________ Reply Separator _________________________________ Subject: Unidentified subject!

They found that the copper corrosion is similar to aluminum, to first order it passivates. After about 40 years the oxide thickness is only about 0.4 mils. Although the an indoor environment was used, it was none the less, very aggressive! Lee Parker Lucent Technologies
