Does anyone have any good suggestions for storage methods when business reasons require an end of life buy of a PLCC which has a tin lead coating on it and the quantity will last for the next six years of production? Obviously these need to be kept as dry as possible, in an environmentally controlled, esd protective dark/cool location, but the practical storage issue of what container to place these in (several pallets worth), strategic separation (in case of a fire or other disaster) and security are also at hand. I am not sure what the shelf life is for the best moisture vapor barrier bags but I am thinking of double bagging the parts so that we can get rid of the card board boxes they are in. I am considering storage at cooler temperatures to slow down the oxidation rate, but what about "nitrogen" purging before pulling the vacuum on the parts. Will either of these methods make a difference? It has been a while since I have worked on a program which kept stock for anything longer than two months. We brainstormed some pretty wild approaches to this today so I know that my management is pretty open to anything still at this point. Obviously lead free will not be a factor for this product until our stockpile is depleted. Thanks in advance.
