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 eliminate 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 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 to guard against ESD damage is desirable but not necessary.

–Attach the ESD ground clip to any frame ground, ground braid, or green-wire ground.

–When working on a double-insulated or battery-operated system, use an ESD common ground or reference point. You can use coax or connector-outside shells on these systems.

–Use the round ground prong of the ac plug on ac-operated computers.
