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.
