Handling Electrostatic

Discharge-Sensitive Devices

Any computer part containing transistors or integr circuits (ICs) should be considered sensitive discharge (ESD). ESD damage can occur when there difference in charge between objects. Protect damage by equalizing the charge so that the part, the work mat, and the person handling the at the same charge.

Notes

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

2.Make sure that the ESD protective devices use have been certified (ISO 9000) as fu effective.

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 s

eliminate static on your body.

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

you

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 lis below, to provide protection that meets the service requirement.

Attach the ESD ground clip to any frame

ground braid, or green-wire ground.

Use an ESD common ground or reference po when working on a double-insulated or battery-operated system. You can use co

connector-outside shells on these systems.

Use the round ground-prong of the AC plu AC-operated computers.

Grounding Requirements

Electrical grounding of the computer is required operator safety and correct system function. Pr grounding of the electrical outlet can be verif certified electrician.
