I heard that Steam Aging (storage) tests would be inappropriate for gold finishes. Is this a correct statement? If so, what are the reasons? How bad is the shelf life of ENIG

Given that you're seeing it on nearly every part, we tend to lean towards Dave's explanation. We wouldn't expect outgassing from the pad to be an issue (at least, we've never heard of it before, which doesn't, necessarily, eliminate it as a potentia

We�d say that it�s incorrect that ENIG solderability protection cannot be steam aged. It�s true the immersion tin and silver cannot be steam aged. We believe that most of the issues surrounding the poor performance of ENIG after steam aging is attr
