I was informed about the 3% yesterday as well. The whisker
growth damage is exponential. It takes time to get started, but when
they do, a lot can happen. Because, they can reach a critical length at
certain time, and they are not predictable.

Hi Werner,
Good seeing you again at APEXPO.
I heard at the show of one company whose returns for lead-free products
are running 3% higher than those produced with traditional solders.
With razor thin margins for many products, that is a lot. The remake
doubles the cost...
good money after bad.
Fortunately, there is a long standing, reliable and truly
environmentally friendly solution for making good solder joints and it
is ready to step in when lead-free falls on its face. :-)
The green-washing of lead-free as an environmentally friendly solution
is, IMHO, one of the really sad chapters of this industry's otherwise
great history.
All that was needed was for the politicians to listen to the scientists
and not the self-serving, ill-informed lobbyists.
And so it goes....
Very best,
Joe
