Product lifecycles have become very short with new models being released sooner than ever before. Many manufacturers in industries including automobiles, aviation and avionics, military and railway must guarantee the availability of replacement parts (including PCBs) for 10 or even 20 years. This demands the advance purchase and extended storage of components and materials. Further complicating the problem is that most components cannot be stored for more than a few years without very special handling procedures.
IPC JEDEC Standards
Though the original document was released almost two decades ago, and new technologies have been introduced since, IPC/JEDEC J-STD-033 addresses a broad range of fundamentals regarding moisture-sensitive devices and their proper handling. Updated several times since its initial publication, the 2012 Rev C clarified some storage time definitions, but very long term storage of the extent faced by manufacturers mentioned above is not completely addressed.
