We, along with everyone else, have to eliminate the use of TMS for rosin flux 
removal.  We are in the process of switching over to water soluble flux for all 
machine, hand, and SMT soldering.  A Westek in-line cleaner has been purchased, 
although not on line yet (completely closed loop with zero discharge).  It was 
realized that the need still existed to remove organic material from PWB 
assemblies (finger oils, acrylic conformal coating, occasional rosin flux, 
etc.) so we also purchased an S&K system which uses an IPA/cyclohexane blend.  

This decision was based on many months of evaluating alternative methods of 
removing rosin flux.  If anyone would like to discuss this further, please call 
me at 516-595-5879.
