Electrostatic Discharge Information
Electrostatic discharge (ESD) can damage or destroy electronic components .
All work on electronic assemblies should be performed at a static-safe work
station. Figure 1-3 shows an example of a static-safe work station using two
types of ESD protection:
Conductive table-mat and wrist-strap combination.
Conductive oor-mat and heel-strap combination.
Both types , when used together , provide a signicant level of ESD protection.
Of the two , only the table-mat and wrist-strap combination provides adequate
ESD protection when used alone .
T o ensure user safety , the static-safe accessories must provide at least 1 M
of isolation from ground. Refer to T able 1-2 for information on ordering
static-safe accessories .
W A R N I N G
These techniques for a static-safe work station should not be used when
working on circuitry with a voltage potential greater than 500 volts .
