Good afternoon all,

 

I am trying to track down the specific cleanliness specs for electronic
assemblies prior to conformal coating.  (ie < 14 micrograms/cm sq).
What document is this actual measurement listed in?  (MIL-STD-28809)?
Hasn't that been cancelled and superseded by another document?

 

Please advise where I can get a copy of this cleanliness spec.

 

Thanks,

 

Rich
