6.1.3 Cleaning procedure
Items required:
•
Low pressure compressed air (solvent free).
•
Cotton swabs.
•
Lint free cleaning cloth.
•
Isopropanol.
•
Illuminated magnifier or microscope (factor 5 to 10)
NOTE: Isopropanol that contains additives should not be used for cleaning connectors as
it may cause damage to plastic dielectric support beads in coaxial and microwave
connectors. It is important to take all necessary safety precautions when using
chemicals or solvents.
•
Remove loose particles on the mating surfaces and threads etc. using low-pressure
compressed air.
•
Clean surfaces using Isopropanol on cotton swabs or lint free cloth. Use only sufficient solvent
to clean the surface. When using swabs or lint free cloth, use the least possible pressure to
avoid damaging connector surfaces. Do not spray solvents directly on to the connector surfaces
or use contaminated solvents.
•
Use the low-pressure compressed air once again to remove any remaining small particles and
to dry the surfaces of the connector to complete the cleaning process before using the
connector.
6.1.3 Cleaning connectors on static sensitive devices
Special care is required when cleaning connectors on test equipment containing electrostatic
sensitive devices. When cleaning such connectors always wear at least a grounded wrist strap and
observe correct procedures.
6.2 Interface Dimensions and Gauging
It is of the utmost importance that connectors do not damage the test equipment interfaces to
which they are connected. Poor performance of many coaxial devices and cable assemblies can
often be traced to poor construction and non-compliance with the mechanical specifications. The
mechanical gauging of connectors is essential to ensure correct fit and to achieve the best
performance. This means that all coaxial connectors fitted on all equipment, cables and
terminations etc. should be gauged on a regular basis in order to detect any out of tolerance
conditions that may impair the electrical performance.
6.2.1 Gauging connectors
A connector should be gauged before it is used for the very first time or if someone else has used
the device to which it is connected.
