Hi Joe,
What is the environment that the conformal coating needs to protect the
assembly from and is this an exercise to eliminate solvents altogether?

Subject: [TN] Conformal coating properties question
Fellow Techs,
I have been asked to help select an alternate material that cures by
moisture / cross-linking (and not by solvent evaporation such as
HumiSeal type AR 1B31). There are a range of mainly type UR materials to
select that offer moisture cure and have differing Tg, CTE and Young's
Modulus properties.
I am very interested in any information that relates a conformal coating
materials Tg, CTE and Young's Modulus to a coating's capability, board
reliability etc..
Thanks again
-Joe
