[Premium-Rx] lead free solder tin whiskers

[Henry A. Kolesnik]

I was amazed at how thin the whiskers are and it seems like most circuits would clear them out unless specifically designed not to.  Are Toyota circuits that low current?

These are very interesting articles. The problem of maintaining the 
current crop of premium radios is going to become very much more 
difficult as the years go by. Enjoy them now! What is perhaps sad, is 
that the whole changeover to Pb free solders is based on misinformation 
about Pb leaching. Ah well ....
