Hello TechNet!

I've got a customer who is looking to protect an IC from exposure to 
UV.  It is a tiny 24 ball BGA (2.3 mm square).  They are suggesting a 
dam and glob-top solution, but I'm concerned that there isn't enough 
room around it (very, very small board).  I've suggested a dab of black 
conformal coating material on a brush.  Any other great solutions?
