EOL is a subject we encounter more and more. The after-sales business (sometimes with spare parts obligations to be contractually guaranteed) can become a real risk factor. We work with a service provider who has developed a method for long-term preservation. If desired, components are stored there in a highly secure warehouse and are thus available for many years. Particularly today, when it is common that individual components are no longer produced (last time buy, EOL), this represents an alternative for continuing to provide components under optimal conditions for years.
