Hello TechNet,

I would like to sense the best practices in terms of solder mask surface tension with respect to conformal coating adhesion :

-          Which standard/test method are you using?

-          Which requirement (e.g. minimum value in dyn/cm²) would you accept for the various CC types (acrylics, urethanes, silicone, parylene)?
Thanks in advance for the insights.
Best regards,

Arnaud Grivon
