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?
