MIL-STD-883, MIL-STD-750 and J-STD-002 will all have to be updated to consider
the "lead free" solders used during assembly.

It should be noted that the test methods already covers "lead free" finishes on
the component terminations (i.e gold and NiPd).

        Subject:        [LF] Solderability standards

        The last 50 or so E-mails underscore my original point - time spent
debating
        is time NOT spent finding a solution!  So again, please don't use the
"we
        don't have enough time" excuse for not getting ready for these lead-free
        initiatives.  There has been ample time to get ready, but for whatever
the
        reason, many have chosen not to, perhaps hedging their bets that this
whole
        thing would just blow over.  Having to scramble now is the price to pay
for
        losing that bet.

        I for one would like to see this forum re-focus on finding solutions!!
        Perhaps another E-mail forum could be started with more of a "Lead-free
Soap
        Box" theme?

        Along those lines, does anyone know of a standard for doing
solderability
        testing on lead-free packages?  Mil-Std-883, Methods 2003 and 2022 are
what
        we always used in the past.  However, those both call for a Sn/Pb solder
        dip.  It doesn't make much sense to characterize a lead-free package
using a
        leaded solder dipping process, since any customer who would ask for a
        lead-free package is almost certainly not going to be using lead on
their
        PCB.  Any pointers or suggestions would be greatly appreciated.

        Best regards,

        Bob
