ESD Information
Protection from Electrostatic Discharge
Electrostatic discharge (ESD) can damage or destroy electronic components. All work on electronic
assemblies should be performed at a static-safe workstation. Figure 1 shows an example of a
static-safe workstation using two types of ESD protection:
❏Conductive table-mat and wrist-strap combination.
❏Conductive floor-mat and heel-strap combination.
Both types, when used together, provide a significant level of ESD protection. Of the two, only the
table-mat and wrist-strap combination provides adequate ESD protection when used alone. To ensure
user safety, the static-safe accessories must provide at least 1 megohm of isolation from ground.
WARNING These techniques for a static-safe workstation should not be used when
working on circuitry with a voltage potential greater than 500 volts.
Figure 1 Example of a Static-Safe Workstation

6Installation Note N9038-90019
LISN Control Upgrade
Handling of Electronic Components and ESD
The possibility of unseen damage caused by ESD is present whenever components are transported,
stored, or used. The risk of ESD damage can be greatly reduced by paying close attention to how all
components are handled.
❏Perform work on all components at a static-safe workstation.
❏Keep static-generating materials at least one meter away from all components.
❏Store or transport components in static-shielding containers.
CAUTION Always handle printed circuit board assemblies by the edges. This will reduce the
possibility of ESD damage to components and prevent contamination of exposed
plating.
Test Equipment Usage and ESD
❏Before connecting any coaxial cable to an analyzer connector, momentarily short the center and
outer conductors of the cable together.
❏Personnel should be grounded with a 1 megohm resistor-isolated wrist-strap before touching the
center pin of any connector and before removing any assembly from the analyzer.
❏Be sure that all analyzers are properly earth-grounded to prevent build-up of static charge.
For Additional Information about ESD
For more information about preventing ESD damage, contact the Electrical Over Stress/Electrostatic
Discharge (EOS/ESD) Association, Inc. The ESD standards developed by this agency are sanctioned
by the American National Standards Institute (ANSI).
