Just for grins, how many have run into variation in component materials and
processes such as a different die source, adhesives, process profiles, cure,
etc. within a specific date code?
Scary, isn't it.

Subject: Re: [TN] Proposed lifting of component date code restrictions


There are many instances in everyone's career where we sorted by or found
problems with date codes.  Many times that was the only sort criteria.  Just
got bit again from a broker for a very old part, just finished our 450 PC
rework.

It also makes me very concerned having been in serious medical device
assembly.  Now the proposal would allow what ever date code out and lose
that traceability for the next generation of pacemakers and various other
life support systems or military applications like a shuttle.  The
manufacturer's may know more about handling, processing, etc but the
distributors don't know nor do the brokers.

Not one manufacturer out there is always providing 100% quality, there are
problems.  The only thing that can make this a possibility in my mind would
be if the manufacturers are going to support all parts when an issue comes
up and the financial burden to remove all from inventory instead of a
specific batch.

Don't let them lose the date code that we all have come to depend on.
