Irrelevant for backplanes, but for circuit boards, would any UV-erasable PROMs want to be
checked to ensure their caps/covers are still in place before exposure to sunlight?
Definitely. It takes a while, but even behind window glass (which is barely transparent
to short wavelength UV) EPROMs can eventually lose their content. It happened to a friend
who had a machine with no top cover, on a desk under a window, after about 5 years. But
in direct sunlight, certainly just hours, and possibly just several tens of minutes if
you're unlucky.
Is the same true even if they have either a paper stick or a foil sticker over the eprom
window? I would *guess* that stickers slow or stop the process altogether.
