 Will it ever come out that the idiotic move by the European community
dictating the removal of lead from solder, and thus weakening circuit boar
soldered connection, and thus the grand problem of faulty wiring?

And are we being forced into the same conundrum by our idiotic management
teams and politicos?

I understand that the lead solder directive specifically excludes
Aerospace 'and other high criticality' applications, which rather
gives the game away that they know it fractures and don't care about
the consumer !

AWEM
(who has a cache of reels of 60/40 that probably will last him out)

So what clues do we have about the wire harness problem other than this
ghost?

Aerospace applications are exempt
from RoHS solder requirements.

Conveniently.

From Electronic Design magazine,
August 3, 2007

"The defense and aerospace industries are exempt from the European
Union's RoHS directive, so they haven't had to shift to lead-free parts.
The exemption was granted based on the need for the high reliability of
leaded solder in the high-stress environment and long shelf life of
defense and aerospace equipment. Lead helps mitigate the growth of tin
whiskers, which can grow on pure-tin solder, then break off, potentially
causing shorts."
