適用范圍：Although it has always existed to some extent, obsolescence of electronic components, andparticularly integrated circuits, has become increasingly intense over the last few years.Indeed, with the existing technological boom, the commercial life of a component has becomevery short compared with the life of industrial equipment such as those encountered in theaeronautical field, the railway industry or the energy sector.The many solutions enabling obsolescence to be resolved are now identified. However,selecting one of these solutions must be preceded by a case by case technical and economicfeasibility study, depending on whether storage is envisaged for field service or production.Remedial storage as soon as components are no longer marketed.Preventive storage anticipating declaration of obsolescence.Taking into account the expected life of some installations, sometimes covering severaldecades, the qualification times, and the unavailability costs, which can also be very high, thesolution to be adopted to resolve obsolescence must often be rapidly implemented. This is whythe solution retained in most cases consists in systematically storing components which are inthe process of becoming obsolescent.The technical risks of this solution are, a priori, fairly low. However, it requires the perfectmastery of the implemented process, and especially of the storage environment, although thismastery becomes critical when it comes to long term storage.All handling, protection, storage and test operations should be performed in accordance with thetechnology requirements of the component.
