Following from the EMPF HelpLine:
The Naval Surface Warfare Center, Crane IN has some "life time buys" of 
components that are projected for Loooooong term--maybe up to 20 
years---storage. Ms. Shine Rominger, 812.854.5256 has been involved 
specifically with solderability issues (testing, preservation, restoration). 
Call her after next Tuesday to discuss further.

     The parts should be checked for solderability about every six months.

We have a member who is specifying a large number of a soon-to-be
discontinued plastic DIP IC. These parts will then be stored up to two
years at their facility.

His concern is with handling of these parts, particularly how to store
them (vapor barrier bags, for example?). He is well aware of the
precautions necessary for SMDs, but doesn't know whether these apply to
DIPs too. Any advice?
