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.
 
regards,

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,
