Thanks  Denny! A few of us were questioning that the data was so old,
crust was  forming, which is appropriate for a pie chart. Let us know if
you get any  updates.

Dewey, 
 
I only have the year end 2003 data at hand today.  And, remember how  the 
Suppliers Council tracks this data - by the revenue from the chemistry - not  by 
the square feet of boards.  So you have to use some multiplier or factor  to 
estimate square feet of boards, but this is not too bad as it leaves the  
metals (gold) value out of ENIG.  
 
Here were the percent of chemistry sold for finishes in the US in  2003:
 
HASL- 22.4% (I can't tell if this includes the metal added to the solder  pot 
- doubt it)
 
OSP – 34.3%
 
ENIG – 15.0% without metal content (gold)
 
Imm Sn – 7.1%
 
Imm Ag – 13.6%
 
Other metallics – 7.5%, presume this is electroplated nickel gold or  
reflowed tin lead.
