NASA: "Damn the tin whiskers, launch the shuttle"

[Robert Baer]

On the subject of the shuttle electronics which DO have tin whiskers;
NASA has decided to ignore best advice on the new launch and push ahead
anyway.

Memories of O-Ring discussions and launch site ambient temperatures
come to mind.

Does the shuttle have to comply with RoHS?

Good day!

Management can rule law of physics I presume..

What management team have you ever seen NOT believe that?

No.

More proof that you are not really an engineer.

NASA - "Damn, I knew we shouldn't have gone with that lead-free
solder. Oh well, we'll get it right on the next shuttle - too bad
about the crew though..."

Military, medical & aerospace electronics are all exempt because the
dangerous unreliability of lead-free solder are all too well known!!!!!

We'r just waiting for the misstake that someone put a RoHS board into any of
these kind of application areas. Like wifi/gsm equipment in airplanes, that
need to source power somewhere. Or careless repair ppl

Whats NOT funny is that these risks are VERY real. Not just tin whiskers,
but also the vibration causing joint failure.

You should both be taken out and shot.

Remember, for a lot of electronics, the government has a COTS mandate
(in order to save money).

Airplanes have these things called circuit breakers....

COTS toys short out - breaker pops - boring but safe flight

Suppose someone mixes up replacement material for more critial equipment ..?

You also have the medical arena, automotive electronics, or simple whisker
prone electronics controlling non-whisker prone one. Like a PC controller..
