I would like to get an answer for some questions:
1. I need full description of how to strip electroless nickel from
copper? and what type of chemicals and conditions can be used to
achieve that?
2. I need a description of stripping of gold?
best regards

Dear Mr Jamjoom,
For stripping NiP from copper there are commercial strippers on
the market. You can try this recipe:
60 g/l Sodium hydroxide
120 g/l Ethylene diamine
60 g/l m-nitrobenzene-sulfonicacid
Temperature 75 C.
About your question for a description of stripping of gold, what's
the base metal?
Kind regards,
