  • I recall some discussion (maybe online, maybe at work), not necessarily about un-used raw materials, but solder already applied to circuits. Specifically toward the phenomena called "tin whiskers"; small bits of solder which break off already soldered connections.

    This also devolved into some arguments about not using lead free solder in critical application, since it just hasn't has as many years in service and studied as thoroughly.
    Something to chew on. I'm not making satellites but I want my stuff to work for a few years and not burn down my house.

No public wish lists :(
