Hello,

When encountering conformal coating to solder mask adhesion problems, I 
guess one of the usual place to look first is the cleanliness of the boards. 
 But what if we don't have any problems applicating the acrylic coating 
(indicating that the board musn't be that dirty), the Omega test results are 
as usual (I know there can be some escapes) and, apparently, nothing seems 
wrong elsewhere ?

Since I'm not that much experienced, I would appreciate any advice on 
adhesion of conformal coating and any reference to publications, past 
experience or else.

Thank you.
