Morning Technetters,

Advise needed. We used to use dipped in method using a conformal coating
machine but as the latex used to cover the forbidden area need at least
a few hours to cure, we cannot afford the time. Due to the extremely
tight schedule given to us, we have engineers sending in assembled
boards in the morning and expect us to perform miracles and have them
ready before lunch.

We are now using the hand brush method but as mentioned, due to the
extremely tight schedule, is there any way to measure the coating
thickness without say, measure assembled board before coat, after that
coat one side-measure again, before coat the other side & measure again
in order to get the individual side coating thickness?

We may have used the wrong approach and I desperately need some advise
from you guys and gals. More over, should we revert back to dip in
method, how are one going to measure the coating thickness of one side
and then protected it before proceed to the un-coated side? Any
suggestions is greatly appriciated.

Regards
S L Ong
