I don't think that continuously finding customers that have ENIG problems makes you and Lee the most unlucky individual on the planet. Actually you may be among the most lucky individuals who have business come looking for you rather than you looking for business. Regards, George George M.

However, I was wondering if you could further discuss the "flash" vs. "ENIG" issue. I have been using ENIG on my Pb-free assemblies for about 7 years with very little problems. If I am missing something further education would be extremely helpful.

To avoid the problem I suggest a flat metal finish such as immersion silver or flash gold (not ENIG) Best regards Lee J.

Does selective solder strip and reflow plating, SSSR, have a significant advantage over HASL? Any comments relating to platting finish would be greatly appreciated. I thank you for your comments.
