I sent this message last week . No one responded . Maybe this week ? Hi We are running in our plant Electroless nickel - Immersion Gold ( ENIG ) finishing for PCB based on Atotech chemistry . Phosphour content is in middle range ( average 9% ) . One of our customers request low phosphour content - less than 7% . We ae trying to force the chemistry to plate Nickel with such content of phosphour by rising the temperature , increasing volume load ( sq cm per liter of working solution ) etc , but untill now we do not have stable process parameters . Any recommendation for Atotech chemistry or someone else chemistry to achieve the goal of phoshpour content in nickel less than 7% ???
