Hi Peter, IPC LF LIstservers,

<Before we get too far down an alternate path, I think the major concern
isn't the solder joint failing, it is the growth of whiskers causing short
circuits.  A decent manufacturer will create lead free solder joints that
are at least as robust as leaded joints.  In some cases, the change to lead
free is causing manufacturers to learn more about their processes, probably
leading to better quality.  The whisker problem is well documented.  It's
effect is not, and may never be, but is often overblown.  most whiskers
will not grow long enought to cause a problem, will not fall off into
another circuit, or will fuse themselves.  And when they do cause a
problem, the consumer will just accept that their iPod no longer functions,
and throw it in the landfill and buy another.>

One of my fears is that the real data will be lost. As we move to China
and other past cheap places the expectation that stuff "craps out" due to
poor quality and a learning culture will be prevent us from seeing LF
failures independently.

Yours in Engineering, Dave
