Solder is used extensively in satellites nowadays. The catch, though, is that you must use leaded solder, because the lead dramatically decreases the occurrence of tin whiskers. RoHS has been rather annoying in the aerospace industry, because anything RoHS compliant can't safely fly.

Weren't a lot components RoHS-compliant intrinsically anyway, without any change in process whatsoever?
