Gold is the most noble metal of all. Gold is essentia
Steve
Gold is the most noble metal of all. Gold is essentially inactive which is also why it is so valuable and difficult to dissolve. If oxides are forming on gold surfaces it is usually because the under coating is exposed at the surface or there are impurities in the gold. Since bondable gold is usually pure gold, impurities should not be present. It the problem is organic films, (which are not complexed to the gold) the problem may be residual or packing.

Subject: [TN] Wire bondable gold pads
Good Morning to all,
We manufacture various circuits with electroplated wire bondable gold.
As the final operation before packaging and shipping we plasma clean.
Our customer is under the impression that the gold can contaminate
during shipping and storage. My question is do other suppliers do
special nitrogen/vacuum packaging of product like this to prevent this
or is this something that should not be happening. Thanks in advance.
Steve Kelly
