IMHO, if stored in a reasonably clean environment without special
conditions, packed assemblies have an almost indefinite lifetime,
especially with professional-quality components. I have, on several
occasions, the last only this week, plugged in items 5-10 years old and
they have worked perfectly every time. I would make one proviso, that
the circuitry is neither ultra-high impedance (>10E12 ohms) or very
sensitive to dielectric constant of the substrate.
