Safety 4 - 3
ESD
Precautions
•
Assume all circuit packs containing electronic (solid-state)
components can be damaged by ESD.
•
When handling circuit packs (storing, inserting, removing, etc.) or
when working on the backplane, always use the appropriate
grounding procedure: either a wrist strap connected to ground or,
when standing, a heel strap with a grounded dissipative floor mat.
•
A grounded person must never hand an unprotected circuit pack to
an ungrounded person. A static discharge from the ungrounded
person through the circuit pack to the grounded person could cause
an electrostatic discharge failure. All persons and equipment at a
work location must be at the same common ground potential to be
static safe.
•
Handle all circuit packs by the faceplate or latch and by the top and
bottom outermost edges. Never touch the components, conductors,
or connector pins.
•
Do not rub or wipe circuit packs to clean them unless you and the
circuit pack are at the same ground potential.
•
Observe warning labels on bags and cartons. Whenever possible,
do not remove circuit packs from antistatic bags or cartons until
ready to insert into the rectifier. Otherwise, open all circuit packs at
a static-safe work position with wrist straps and dissipative table
mats.
•
Upon removal from the rectifier, immediately put circuit packs into
antistatic packages. Always store and transport circuit packs in
antistatic packaging. Shielding is not required unless specified.
•
Keep all static-generating materials away from all circuit packs.
These materials include common plastics such as food wrappers,
clear plastic bags, styrofoam containers, packing material, drinking
cups, notebooks, and nonconductive plastic solder suckers. The
insulation on small hand tools does not represent a static hazard.
•
Keep adhesive tape (Scotch, masking, etc.) away from
static-sensitive devices.
•
When soldering static-sensitive semiconductor devices, the
soldering iron must be grounded to the work table which must also
be earth grounded.
•
Whenever possible, maintain relative humidity above the
20-percent level.
•
Minimize electrostatic discharge when handling circuit modules.
