A quick review of moisture/time sensitive packages in our stockroom shows
that:
moisture sensitivity related material (shelf life/ prebake/sealed
date/etc) is included on the outside bag as well as mfr/mfr part number/
p.o.#/ etc on material that comes from distributors or has not been
repackaged by consigned suppliers.
I also have examples in which a moisture-sensitive programmable supplied
on tape and reel would also include the moisture sensitve information on the
reel itself as well as the outside bag or box. I have a gut feeling that
this is strictly up to the packaging specs of the mfr or distributor who has
done the final blasting of the programmable. If your distributor offers
programming of components, they may be able to mark both the reel and
outside packaging. A good question to ask when you are quoting availability
of material or sourceing a new distributor.
If a device is distributed as a blank and then programmed or tape and
reeled by an outside source, you may not have this information carried over
from the outside packaging to the new reel. Customer part numbers and p.o.
information are usually carried over to the new reel.
As far as moisture/time sensitive components supplied in stick or matrix
tray form, I do not show evidence that there is any indication of moisture
sensitivity data or customer part number or purchase order information on
the sticks or trays. This information is supplied only on the outside bag
or box the sticks and trays were sealed in.
Hope it helps. --Dean Lillibridge

Our experience shows all the information is on the outside of the sealed
bag. Customer supplied parts are usually pre-marked (by the customer)
with their part number, reference designator, etc. on the outside only
and the bag is still sealed. For parts that we purchase, our receiving
inspection writes the info on the outside of the sealed bag. The sealed
bags are not opened until ready for use.
