Preserving Connectors.

WARNING
Water-displacing corrosion-preventive compound vapors can be harmful to eyes and lungs. To avoid harm,
keep the corrosion preventive away from heat, wear protective goggles and use in a well-ventilated area.
CAUTION
Use water-displacing corrosion-preventive compound, Type III, Class 2 only, on internal connector surfaces.
a.
Where possible, hold connectors with opening pointing slightly downward. Spray an even, thin film of compound
over the male pin area of the connector and into the female socket openings.
CAUTION
Use water-displacing corrosion-preventive compound, Type I only, on external connector surfaces.
b.
After preserving connectors internally, assemble connectors. Wipe the outer surface of the connector shell with a
lint-free cloth dampened with cleaning compound. Spray a thin coating of water-displacing corrosion preventive
compound, Type I, on all external surfaces of the connector set. Ensure the area where the connector set comes
together is completely covered.
c.
Wipe away excess spray with a lint-free cloth.

Soldering Techniques.
WARNING
Solvent cleaning compound MIL-PRF-680 Type III is an environmentally compliant and low toxic
material. However, it may be irritating to the eyes and skin. Use protective gloves and goggles. Use in
well-ventilated areas. Keep away from open flames and other sources of ignition.
Particles blown by compressed air are hazardous. DO NOT exceed 15 psi (103 kPa) nozzle pressure
when drying parts with compressed air. Use a maximum of 30 psi (207 kPa) when cleaning compo-
nents. DO NOT direct compressed air against human skin. Failure to follow this warning may cause
injury or death. Make sure air stream is directed away from user and other personnel in the area. To pre-
vent injury, user must wear protective goggles or face shield.
a.
Solder connections must be bright and clean before soldering. Remove dirt and grease from connections with sol-
vent cleaning compound and small, stiff fiber brush.
b.
Solder must be non-acid type. Rosin flux can be used.
c.
All wires, parts and soldering iron must be pretinned for good connection and maximum transfer of heat.
d.
Clean all solder joints with acid-swabbing brush and cleaning compound after soldering to obtain a clean, bright
surface.
