Paul Actually, we no longer use dye, per say. We use the stuff machinists use for staining metal. Look here for hints: * <http://www.ivf.se/Elektronik/dye_penetrant/edefault.htm> * <http://www.amkor.com/products/notes_papers/SMTAI_2000_Darveaux.pdf> * Dye-and-pry failure analysis (technique described in B. Mullen, A. Hertz, B. Miles, and R. Darveaux ["Plastic Ball Grid Array Assembly," Ball Grid Array Technology, J. Lau Editor, McGraw-Hill, Inc., New York, 1995]) * Process Sciences Inc [ http://www.process-sciences.com ] wrote a newsletter, fairly recently, with a section on dye & pry. This is a messy process [and there is no return]. What are you looking to clean?
