• Wear working garment made of 100% cotton to avoid electrostatic
discharge.
• 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.
• Store and ship circuit packs and components in their shipping
packing. Circuit packs and components must be packed and
unpacked only at workplaces suitably protected against build-up
of charge.
• Observe warning labels on bags and cartons. Whenever possible,
do not remove circuit packs from antistatic packaging until ready
to insert them into slots.
• If possible, open all circuit packs at a static safe work position,
using properly grounded wrist straps and static dissipating table
mats. If a static dissipating floor mat is used, be sure that it is clean
to ensure a good discharge path.
• Always store and transport circuit packs in static safe packaging.
Shielding is not required unless specified.
• Keep all static generating materials such as food wrappers,
plastics, and styrofoam containers away from all circuit packs.
Upon removal from bay, immediately put circuit packs into static
safe packages.
• Whenever possible, maintain relative humidity above 20 percent.
To reduce the possibility of ESD damage, assemblies are equipped with
grounding jacks to enable personnel to ground themselves using wrist
straps (Figure 1, Static Control Wrist Strap (page -xxiv)) while
handling circuit packs or working on an assembly. The jacks for
connection of wrist straps are located at the upper right-hand corner of
each assembly and are labeled. When grounding jacks are not provided,
an alligator clip adapter enables connection to bay frame ground.
