Miguel Solder balls/splashes??!!! We're using a VOC free water based flux for wavesoldering and Kester 951 for hand soldering. We've had instances where repair operators use the water based flux for repair, I know, I know, molten solder and water don't mix well. To continue, you may want to try baking the boards to remove moisture trapped inside and/or limit the amount of flux being used by repair people, flux pens work well. Derek Humble S.C.
