Marcelo, First of all, Why do you want to dip the boards into acetone for 15 minutes? If boards are conformal coated with parylene, epoxy or some of the urethanes, probably not too much will happen. If they aren't coated & depending on what they're made of ... you'll probably get lots of absorption into the laminate ... vacuum baking will probably be required to remove it ... In addition acetone is a good solvent which evaporates quickly so if you're trying to clean the boards you will just dissolve any acetone-soluble contaminates and the evaporating solvent will deposit them elsewhere on the assemblies.
