Hello all, Just curious as to what type of chemistries most people prefer to use and what produces the best results. We currently have an EMC Global Technologies Cyber Clean 1000 Model 32P system. We use Isopropyl Alcohol currently to clean stencils, but I am not very happy with the results. To me, it doesn't appear to clean very well, as well as, leaving a residue on the screens. We are moving into BGA and very fine QFP products and I am concerned with our current setup. I have samples of Zestron SD 301 compound coming in for a trial.
