3.5 Electrostatic Discharge
This section provides informatio
n and instructions on Electrostatic Discharge
(ESD) product safety. ESD is def
ined below.
ESD
A static electric charge accum
ulates when a body rubs
against clothes, slides again
st a chair, when shoes rub
against a floor, or when ordin
ary plastics are handled,
and so on. The electrostatic c
harge can remain for a
considerable length of tim
e and is discharged when the
body comes into contact wit
h conductive material.
An ESD wrist strap must be us
ed when working with ESD sensitive components,
even in equipment rooms fi
tted with ESD protective floor covering. Although
ESD floor covering reduce
s the risk of ESD, if the wrong type of shoes are
used, or if the person is a
lready charged when they enter the room, the floor
covering in itself does
not protect from this, and therefore an ESD wrist s trap
must be used.
01_0250A
Figure 16 ESD wrist strap
The ESD wrist strap contains a resistor with resistance greater than 1 M in the
cable to protect the operator. The resistance value is low enough to discharge
the electrostatic voltage. The ESD wrist strap must be connected to ground.
Instructions for ESD Wrist Strap Use
1. Place the ESD wrist strap around your wrist and insert the connector at the
other end to the ground (earth) terminal on the equipment.
2. Always use the wrist strap when and where its use is required.
Note: Test the ESD wrist strap regularly.

3.5.1 Handling Printed B
oard Assemblies and IC Components
Note: Treating all
components as if they are ESD sensitive, whether they
have IC components
or not, reduces the risk for ESD and significantly
reduces the opera
ting time between failure.
Caution!
Stop! This product contains components sensitive to ESD. Use an approved
ESD wrist strap, connected to the product grounding point, to avoid damaging
these components.
Caution!
Do! Always use an approved ESD wrist strap when working with sensitive
equipment. Damage to components mounted on printed board assemblies can
occur if an ESD wrist strap is not used.
3.5.2 Storing and Trans
porting Printed Board Assemblies and IC
Components
