Notes:

1. Use product-specific ESD procedures when they

exceed the requirements noted here.

2. Make sure that the ESD protective devices you use

have been certified (ISO 9000) as fully effective.

When handling ESD-sensitive parts:

• Keep the parts in protective packages until they are

inserted into the product.

• Avoid contact with other people.

• Wear a grounded wrist strap against your skin to elimi-

nate static on your body.

• Prevent the part from touching your clothing. Most

clothing is insulative and retains a charge even when

you are wearing a wrist strap.

• Use the black side of a grounded work mat to provide a

static-free work surface. The mat is especially useful

when handling ESD-sensitive devices.

• Select a grounding system, such as those listed below,

to provide protection that meets the specific service

requirement.

Note: The use of a grounding system is desirable but

not required to protect against ESD damage.

— Attach the ESD ground clip to any frame ground,

ground braid, or green-wire ground.

— Use an ESD common ground or reference point

when working on a double-insulated or battery-

operated system. You can use coax or connector-

outside shells on these systems.

— Use the round ground-prong of the ac plug on ac-

operated computers.
