CAUTION
Static discharge can damage any semiconductor component in the
AWG2005.
Precautions
When performing service which requires internal access to the AWG2005,
follow these precautions to avoid damaging internal modules and their
components due to electrostatic discharge (ESD).
1. Minimize handling of staticĆsensitive modules.
2. Transport and store staticĆsensitive modules in their staticĆprotected
containers or on a metal rail. Label any package that contains staticĆsenĆ
sitive modules.
3. Discharge the static voltage from your body by wearing a grounded
antistatic wrist strap while handling these modules. Only service staticĆ
sensitive modules at a staticĆfree work station.
4. Do not remove the AWG2005 cabinet unless you have met precaution
number 3, above. Consider all internal modules staticĆsensitive.
5. Do not allow anything capable of generating or holding a static charge
on the work station surface.
6. Handle circuit boards by the edges when possible.
7. Do not slide the modules over any surface.
8. Avoid handling modules in areas that have a floor or workĆsurface coverĆ
ing capable of generating a static charge.
9. Do not use highĆvelocity compressed air when cleaning dust from
modules.
Susceptibility to ESD
Table 6Ć1 lists the relative susceptibility of various classes of semiconducĆ
tors. Static voltages of 1 kV to 30 kV are common in unprotected environĆ
ments.
