We use both acrylic and silicone conformal coatings on different products. From all of the testing we have done, the silicone performs much better for corrosion resistance and preventing dendritic growth. Jon A.

Could it be the flux residue and not moisture? Anyway, I would recommend an acrylic conformal coating. It is sprayed on (comes in aerosol cans for low volume production), heat cured, and can easily be removed with most solvents. We are using a product from Miller-Stephenson, Danbury, CT, P/N MS-475N.

For a long time we experience returning of many cellular phones due to corrosion, specially after repairing. I thought about using a conformal coating to protect the fresh solder from humidity and moisture. Does anyone has got an experience in this kind of work and could recommend easily removable coating (we do not seek solvent protection), the application method and curing mode (since there are expected many shaded points, UV or any radiation curing does not seem feasible).
