More than political -- the subject could easily be viewed as troll bait.
It's been 'discussed' many times in ser.

It's not a troll.

New data ought be available as to the effects on actual in-service reliability of
lead-free by now. It seems as I expected, anecdotally, that musical equipment
products that tend to see high levels of vibration are suffering.


This subject came back to bite me yet again today. There's a great part
I wanted to use, but we'll have to refinish the pins first if I do, so
I'll see if there's a different part I can use in this application. For
the record, it's a high speed (not full speed) USB peripheral controller
and the lead finish is 98/2 SnCu.
I consulted with a few of the manufacturing people and one of the
biggest problems with RoHS profiles is the solders aren't eutectic, so
getting a proper bond is more difficult quite apart from the problem
with tin whiskers.

What's the application that requires this refinishing ?
