Cleaning the assemblies
should be preformed as necessary to remove foreign matter
and flux residues. Assemblies must be cleaned in a manner
such that the intrusion of cleaning material into the
drive does not occur. Elmo products are not hermetically
sealed; all the assembled boards are coated with
HumiSeal conformal coating type 1B31.
Care should be taken to avoid forcing liquid into the drives.
Mounting the drive with the belly recessed into
a cutout is at most risk from a high-pressure aqueous wash.
This cleaning method must be avoided.
Intrusion of cleaning solvent into the drive can damage it by
dissolving the HumiSeal coating and creating corrosive conditions
inside the drive.
As with any electronic component, corrosive and/or mobile ions
that may be present in RA or OA flux residues should not be
allowed to remain on or under the drive after soldering. The
cleaning process should done by hand using a brush.
