HP 8590 E-Series - Electrostatic Discharge; Example of a Static-Safe Work Station

Electrostatic Discharge
Electrostatic discharge (ESD) can damage or destroy electronic components. All work on
electronic assemblies should be performed at a static-safe work station. Figure l-5 shows an
example of a static-safe work station using two types of ESD protection:
H Conductive table-mat and wrist-strap combination.
n 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 MR of isolation from
ground. Refer to ‘fable l-4 for information on ordering static-safe accessories.
Warning
These techniques for a static-safe work station should not be used when
working on circuitry with a voltage potential greater than 500 volts.
