If it's conductive at all it could bridge contacts on a circuit board.

  Due to https://en.wikipedia.org/wiki/Whisker_(metallurgy) https://en.wikipedia.org/wiki/Whisker_(metallurgy) I believe leaded solder is still the norm for aerospace applications.

    It is, also in my experience boards get a conformal coating to minimize baby risk of FOD being an issue with the electronics.

      Yeah they do a lot of individual things to bullet proof satellites because you can't repair them and they cost millions (generally, cheaper satellites are starting to be used more and more).

      They do, but for small scale projects like satellites we tend to push con-coat until we have a good confidence the unit is working. Removing conformal coating to replace a failed component or change a resistor can be quite tricky, especially for epoxy based coatings. So there is a long time without any coating (up to spacecraft assembly).
