Cleaning Connectors
Clean connectors are essential for ensuring the integrity of RF and microwave
coaxial connections. Refer to Table 6-3 on page 6-4 for part numbers for
isopropyl alcohol and cleaning swabs.
1. Use Compressed Air or Nitrogen
Use compressed air (or nitrogen) to loosen particles on the connector
mating plane surfaces. Clean air cannot damage a connector or leave
particles or residues behind.
You can use any source of clean, dry, low-pressure compressed air or
nitrogen that has an effective oil-vapor filter and liquid condensation trap
placed just before the outlet hose.
Ground the hose nozzle to prevent electrostatic discharge, and set the air
pressure to less than 414 kPa (60 psi) to control the velocity of the air
stream. High-velocity streams of compressed air can cause electrostatic
effects when directed into a connector. These electrostatic effects can
damage the device. Refer to “Electrostatic Discharge” on page 3-1 for
additional information.
2. Clean the Connector Threads
Use a lint-free swab or cleaning cloth moistened with isopropyl alcohol to
remove any dirt or stubborn contaminants on a connector that cannot be
removed with compressed air or nitrogen. Refer to Table 6-3 on page 6-4
for a cleaning swab part number.
a. Apply a small amount of isopropyl alcohol to the lint-free cleaning
swab.
b. Clean the connector threads.
Always use protective eyewear when using compressed air or nitrogen.
Keep isopropyl alcohol away from heat, sparks, and flame. Store in a tightly closed container.
Isopropyl alcohol is extremely flammable. In case of fire, use alcohol foam, dry chemical, or
carbon dioxide: water may be ineffective.
Use isopropyl alcohol with adequate ventilation and avoid contact with eyes, skin, and clothing. It
causes skin irritation, may cause eye damage, and is harmful if swallowed or inhaled. It may be
harmful if absorbed through the skin. Keep away from heat, sparks, and flame. Wash thoroughly
after handling.
In case of spill, soak up with sand or earth. Flush spill area with water.
Dispose of isopropyl alcohol in accordance with all applicable federal, state, and local
environmental regulations.
