Plating steel PCB components with "nickel-silver" alloys instead of tin





October 19, 2010

Steel fences plated with tin are often soldered to printed circuit boards and used in electronics. Tin without lead is prone to growing tin whiskers, so it is best to avoid tin plating. Can steel fences instead be plated with a "nickel-silver" alloy such as alloy C770 or C752 (copper, nickel, zinc alloy)?

Tin with a trace of bismuth does not have much of a whiskers problem. Nickel silver will cost a lot more and I wonder about its solderability as it ages.
