Why in heavens name are you using a heat or air cure conformal coating. Why aren't you using a 100% solids UV cure system. You would never have an issue like this Sam Forman MicroCoat Technologies

Hi sforman1 Are you refering that the UV is able to cure on solvent based material too ?

Josh: This is your choice. It wouldn't be mine. Again, I have been doing this for well over 40 years (http://www.m-coat.com) Sam

Have you always used xylene? For our 1B73 we use nothing but 73 thinner from Humiseal or PGMEA at about 50/50 depending on the humidity.

Dennis, I'm amazed that you are having this much trouble. Not trying to be a smart-a**, it's just that 73 is usually pretty easy to fix. Is there anyway you could send me some pics of what you are seeing?

Ricky What silicone coating are you using? Are you using at as a coating or as a potting? In other words how thick are you applying it.

we are using the silicone Dow Corning JCR6101UP. we use it to coat the whole die including the wires.

According to the datasheet, this is a LED encapsulant, is that how you are using it? It also had a section on compatibility, which indicates that it is an addition-cure silicone prone to cure inhibition.
