Shelf life of electro-plated tin-lead on stainless steel| 7 November, 2003
Are there specifications or recommendations for electro-deposited tin-lead plating thickness on austenitic stainless steel that would provide a shelf life of 1 year? 6 months? Would 2 to 3 microns (78 to 118 micro-inches) 90/10 tin-lead over 1.27 microns (50 micro-inches) of nickel be sufficient? What would be recommended for electro-deposited tin on austenitic stainless steel?
