Hello!
         
         We are a supplier of electronic assemblies primarily for the 
         military.  We are in the process of switching over from RMA to 
         water soluble flux (Kester 1189A).  Typically, rosin flux has a 
         density of .890, which the flux density controllers on 
         automated equipment can easily control.  Kester's 1189 flux has 
         a density requirement of 1.2.  Standard flux density 
         controllers can only be dialed up to .999, so how do I control 
         the density of the water soluble flux?  What modifications must 
         I incorporate in my wave soldering process to automatically 
         monitor and control the new flux type?
         
         I would like to hear from those who already use the Kester 
         1189A flux to see how they monitor and control the density.
