Does anyone have a good method for measuring the amount 
of flux applied to a board, on a wave solder machine by a 
spray drum fluxer. I'm trying to determine volume of flux 
applied at various drum RPM's. 
     Only method I'm aware of is to weigh a piece of pr-cut 
mylar, apply flux, then weigh again.

     I want to use this to be able to baseline the wave 
solder equipment at the beginning of the shift and whenever 
a new batch of flux is received.  Sounds crazy, but I have 
noticed differences in spray volume at same drum speeds, and 
same air pressure. I'm using a Soltec Sigma wave.

     Any better ideas ?   

                 Thanks in advance
