Have little to add to Robert's , as Earl said . That is what i meant saying the Ni is gone . To Paul's : heard the phosphorus limit in bath should be kept below 5% ? Is that realistic ?

Would you elaborate please. Once again I see messages where others are experiencing this problem but no absolute solutions. I have read the articles, tried the erasers, stronger fluxes, and pad scraping. No relief. I have learned to dislike Electroless Ni/ Immersion Au boards. I am thinking that HASL or precision pad technologies are much better. At least you can perform your soldering operation. A Circuit Card Assembly (CCA) with the Black Plague can run up scrap costs real fast. Not to mention the possibility of late shipment to the customer because of inability to solder. This is a real problem if you are using Ni/Au boards. So far there are few comments and the issue simply drops out of sight. Are platers/fabricators not controlling their processes or is this a inhouse process issue. We have checked our processes and find no change.
