Hello PICList, I have searched the internet and have had a hard time finding any information on the rate of growth of oxides (and other non conductive or semiconducting thin/thick films) on gold contacts under "normal atmospheric conditions". This is directly related to my gold contact wetting current question. I am trying to estimate how long it would take for a set of gold contacts to stop working without any sort of wetting. Can anybody point me to some publications the describe this? Even links to pay walled papers would be appreciated. -Jason White --=20 http://www.piclist.com/techref/piclist PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
