[s-cars] Tin whiskers

[Mtgadbois at aol.com]

Gentlemen,
 
Since I have a business associate who is very knowledgeable in this area I  
sent him the article previously cited.  FWIW, his return comments to  me follow:
 
"Mark:
 
Mr. Cringley's concerns are completely correct, except for his  parting 
statement that we didn't know what would happen when we began the  switch to 
non-lead solders.  We did know, but nobody listened, or cared --  all the regulators 
jumped on the European "Jane Fonda" "green" bandwagon.
 
The rebuttal at the end re the Tin-Silver-Copper alloys is all wet on two  
accounts.  First, the tin does NOT stop whisker formation -- it is the main  
culprit (copper is the element that seems to do a little suppression of whisker  
growth).  Second, all the various Tin-Silver-Copper alloys still form  
whiskers and are VERY significantly worse than Tin-Lead solders with respect to  
whisker growth.
 
Crazy world."
