There was a survey done by SMT magazine in mid-94 that generated 
the following data, based on the responses received.

Solder Paste:      Aqueous                     30%
                   No-clean                    27%
                   Solvent clean               15%
                   Combination of all three    15%

Contract assemblers (as a group) used 84.2% aqueous solder paste.

When asked about how they were dealing with the CFC issue, 8% 
said they were using an all no clean process.  

This survey is almost two years old, so you may wish to make some 
guesses as to growth rate on an annualized basis to get an 
estimate of the range of possible usage.  While this is a good 
starting point, you should bear in mind that the response % is on 
number of respondents, not on square meters of PWAs produced, 
which would give a better picture.
