Hi Bev,
I would hazard to say that this is a language translation error, because
of course, there is a "LIFETIME for the ABILITY to mass SOLDER" moisture
sensitive devices without *damage*. Now convey this concept into two
concise words in Japanese and you might say something about the
toilette. As a matter of fact, being the end of the day, I can think of
a good way to express such a concept in just a couple of words in
english.

Sokkhon, Paul, others,
Well the supplier's spec sheets AND the label on the bag say the same
thing - solderability time limit. This is from one of the largest
off-shore electronics manufacturers in the world. Is there still a
chance they are completely wrong ? Yeeees, but it doesn't look good.
We are investigating. And also asking if this is true, why?
Rudy, good question about the finish. It is tin over nickel over silver.
I don't know the thicknesses - yet.

You will find all detail about MSD in IPC/JEDEC-J-033A. It talk
about moisture not soldering.

Technetters,
As if we didn't have enough problems with really, really old
parts; part numbers; moisture sensitivity; a few instances of stupid
finishes as suppliers go lead free; but now I have a new one - for me
anyways. We have received virgin parts where the label on the bag says
they only have a SOLDERABILITY LIFETIME of 168 hours after they are
taken out of the bag! This is not a case where one can recover them by
putting them in an oven afterwards! Anyone else seeing this new
pain-in-the-neck development?
regards,
