Electrostatic Discharge
(ESD) Considerations
Electrostatic discharge (ESD) (for example, caused by touching with
the hand) can destroy semiconductor components. The correct
operation of the complete system is then no longer assured.
Electrostatic discharge (ESD) warning

Destruction of components by electrostatic discharge
Electronic components can be destroyed by electrostatic
discharge. Circuit packs must always be kept in antistatic
covers. Use the original packaging if possible
Use a static ground wrist strap whenever handling
circuit packs or working on the Metropolis

system to prevent electrostatic discharge damage to
sensitive components.
All semiconductor components are basically sensitive to electrostatic
discharge. The electrostatic discharge can also affect the components
indirectly using contacts or conductor tracks.
Circuit pack handling precautions
Industry experience has shown that all integrated circuit packs can be
damaged by static electricity that builds up on work surfaces and
personnel. The static charges are produced by various charging effects
of movement and contact with other objects. Dry air allows greater
static charges to accumulate. Higher potentials are measured in areas
with low relative humidity, but potentials high enough to cause damage
can occur anywhere.
Observe the following precautions when handling circuit packs/units to
prevent damage by electrostatic discharge:
•
Assume all circuit packs contain solid state electronic components
that can be damaged by ESD.
•
When handling circuit packs (storing, inserting, removing, etc.) or
when working on the backplane, always wear a grounded wrist
strap such as the one shown in Figure 1, Static Control Wrist Strap
(page -xxiv) or wear a heel strap and stand on a grounded, static
dissipating floor mat. If a static dissipating floor mat is used, be
sure that it is clean to ensure a good discharge path.
