Electroless and sulfamate nickel plating problems

What variables can cause pitting problems from electroless nickel plating (10.5 to 12.0% phosphorous concentration)?

Also, is the salt spray test recommended for the nickel sulfamate process?

Dear Mr Bob

If you plate over 100 µm you must have a type of dummy in your electroless plating bath. And the filtration must be over a filter with 2-5 micron. And make sure that the hydrogen is properly evacuated.
