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.

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.
