Handling Electrostatic Discharge-Sensitive

Devices: Any computer part containing transistors integrated circuits ( ICs) should be considered electrostatic discharge (ESD). ESD damage can occ when there is a difference in charge between Protect against ESD damage by equalizing the cha that the machine, the part, the work mat, and handling the part are all at the same charge.

Notes:

1.Use product-specific ESD procedures when th exceed the requirements noted here.

2.Make sure that the ESD protective devices have been certified (ISO 9000) as fully eff

When handling ESD-sensitive parts:

ŸKeep the parts in protective packages until

inserted into the product.

Ÿ Avoid contact with other people.

ŸWear a grounded wrist strap against your sk

eliminate static on your body.

ŸPrevent the part from touching your clothing. clothing is insulative and retains a charge e

you are wearing a wrist strap.

Ÿ Use the black side	of a grounded work mat
a static-free work surface. The mat is		esp
useful when handling	ESD-sensitive devices.

ŸSelect a grounding system, such as those list below, to provide protection that meets the service requirement.

Note: The use of a grounding system is desi but not required to protect against ESD damage.

–Attach the ESD ground clip to any frame

ground braid, or green-wire ground.

–Use an ESD common ground or reference poi when working on a double-insulated or batt operated system.

–You can use coax or connector-outside sh these systems.

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