The gold over nickel will be better by far... Oxidation of the
tin/lead will be much greater than you will see on any gold surface.
Our experiments with these showed the greatest difference in a
temperature and humidity environment for a length of time.

One of our Engineers has asked me to pass on a question. How does the corrosion
resistance of Electroless gold over Nickel (gold thickness of around 7
microinch) compare to horizontal HASL? The target environment is a marine type
environment (salt spray). The customer does not wish to conformally coat the
end product. If anyone has any experience or data in this area I would be most
grateful.
