        Would anyone be able to comment on relevance to Immersion
        White Tin as a surface finish on Class 3 hardware?

        Further, how about when not soldered (as in pressfit)?

        Lately I've had vendors reach for this finish in pressfit
        applications due to easier control of difficult finished
        hole size tolerances.  The NASA site seems to indicate
        *any* Sn is mil-prohibited as a final finish (still surfing).

        Thanks in advance, and thanks for a good technical thread!
