Place
items
on
a
grounded
surface
before
removing
them
from
their
container.
Always
be
properly
grounded
when
touching
a
sensitive
component
or
assembly.
Avoid
contact
with
pins,
leads,
or
circuitry.
Place
reusable
electrostatic-sensitive
parts
from
assemblies
in
protective
packaging
or
conductive
foam.
Personal
Grounding
Methods
and
Equipment
Use
the
following
equipment
to
prevent
static
electricity
damage
to
equipment:
Wrist
straps
are
flexible
straps
with
a
maximum
of
one-megohm
±10%
resistance
in
the
ground
cords.
To
provide
proper
ground,
a
strap
must
be
worn
snug
against
bare
skin.
The
ground
cord
must
be
connected
and
fit
snugly
into
the
banana
plug
connector
on
the
grounding
mat
or
workstation.
Heel
straps/Toe
straps/Boot
straps
can
be
used
at
standing
workstations
and
are
compatible
with
most
types
of
shoes
or
boots.
On
conductive
floors
or
dissipative
floor
mats,
use
them
on
both
feet
with
a
maximum
of
one-megohm
±10%
resistance
between
the
operator
and
ground.

Grounding
the
Work
Area
To
prevent
static
damage
at
the
work
area,
use
the
following
precautions:
Cover
the
work
surface
with
approved
static-dissipative
material.
Provide
a
wrist
strap
connected
to
the
work
surface
and
properly
grounded
tools
and
equipment.
Use
static-dissipative
mats,
foot
straps,
or
air
ionizers
to
give
added
protection.
Handle
electrostatic
sensitive
components,
parts,
and
assemblies
by
the
case
or
PCB
laminate.
Handle
them
only
at
static-free
work
areas.
Turn
off
power
and
input
signals
before
inserting
and
removing
connectors
or
test
equipment.
Use
fixtures
made
of
static-safe
materials
when
fixtures
must
directly
contact
dissipative
surfaces.
Keep
work
area
free
of
nonconductive
materials
such
as
ordinary
plastic
assembly
aids
and
Styrofoam.
Use
field
service
tools,
such
as
cutters,
screwdrivers,
and
vacuums,
that
are
conductive.
