I am experiencing major discrepancies between Nickel/Immersion gold
chemistries, on contacting a number of suppliers I have three
different recommendations for the Phosphorous content in Nickel as
follows:-
Supplier 1 - 8-10%
Supplier 2 - 10-12%
Supplier 3 - 12-14%
I am under the impression that as the Phosphorous content increases
solderability improves but ductility decreases, does anybody out there
have any specific experience of problems caused by too much/too little
Phosphorous content in Nickel or is the range of 8-14% an acceptable
tolerance band to quote.
