damage by equalizing the charge so that the machine, thepart, the work mat, and the person handling the part are allat the same charge.Notes1. Use product-specific ESD procedures when theyexceed the requirements noted here.2. Make sure that the ESD protective devices youuse have been certified (ISO 9000) as fullyeffective.When handling ESD-sensitive parts:v Keep the parts in protective packages until they areinserted into the product.v Avoid contact with other people.v Wear a grounded wrist strap against your skin toeliminate static on your body.v Prevent the part from touching your clothing. Mostclothing is insulative and retains a charge even whenyou are wearing a wrist strap.v Use the black side of a grounded work mat to provide astatic-free work surface. The mat is especially usefulwhen handling ESD-sensitive devices.v Select a grounding system, such as those listed below,to provide protection that meets the specific servicerequirement.NoteThe use of a grounding system is desirable butnot 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 pointwhen working on a double-insulated orbattery-operated system. You can use coax orconnector-outside shells on these systems.– Use the round ground-prong of the AC plug onAC-operated computers.Grounding requirementsElectrical grounding of the computer is required foroperator safety and correct system function. Propergrounding of the electrical outlet can be verified by acertified electrician.Safety informationIntroduction 21
