Test Capabilities and System Requirements 115Appendix A
Air Quality Requirements As a rule, good air quality is as important for the reliability of your Agilent
TS-5400 system as it is for your production process. Three types of airborne
contaminants are discussed below. The presence of any of these
contaminants at the site will contribute to system degradation, resulting in
lower reliability and higher operating costs.
Corrosive Contaminants Corrosion is a complex form of material deterioration or destruction by
chemical or electrochemical reaction. The presence of corrosive
contaminants (gases) in the atmosphere is very common in industrial
environments. If ignored, corrosion can eventually degrade system
performance by its effects on high-impedance circuits and low-impedance
interfaces. It can also deteriorate most plastics including software storage
media. The effects of corrosive contaminants are usually accelerated at high
humidities or high temperatures.
Corrosives generally cannot be filtered out of the air by normal filtration
methods, and the techniques that must be used for their removal are complex
and costly. If the source of corrosive contaminants cannot be eliminated, the
system should be installed in an enclosed environment with a fresh air
supply at positive pressure.
Particulate Contaminants Particulate contaminants (hard particles) consist of smoke, dust, hair, lint,
fibers and miscellaneous organic and inorganic materials. The presence of
these contaminants in the air can cause system degradation, especially where
disk drives, test fixtures, and low-impedance interfaces are concerned.
Particulate contaminants can be filtered from the air, and appropriate filters
should be included with any air conditioning installation. Also consider
installing “No Smoking” signs in the area. Tobacco smoke is a well-known
factor in fixture contact contamination. It causes false failures leading to
unnecessary DUT repairs and higher production costs.
Viscid Contaminants Viscid contaminants are oily or sticky airborne substances that can be
deposited on the system's electronic and mechanical parts. Besides
contributing directly to system degradation, viscid contaminants collect and
hold particulate contaminants and make cleaning very difficult. Viscid
contaminants can be removed from the air by filtration, but the elimination
of their source, if possible, is preferable.
Temperature
Requirements
The Agilent TS-5400 system is designed to operate in the range from 5 °C
to 40 °C (41 ° F to 104 °F).
Cooling Requirements The TS-5400 system cabinet comes equipped with two 200 – 240 volt
extractor fans which draw air primarily through the opening at the bottom of
the rear door and exhaust it through the vented top of the cabinet. In a
fully-loaded TS-5400 system, the fans must be operational to prevent
unacceptable heat rise inside the cabinet.
Humidity Requirements The Agilent TS-5400 system is designed to operate in the range from 5
percent to 80 percent relative humidity (non-condensing).
If the system is subjected to condensation, as if moved from a cold loading
dock into a warm (and damper) environment, allow at least 24 hours for the
