Handlingdevicesthataresensitivetoelectrostaticdischarge

Anycomputerpartcontainingtransistorsorintegratedcircuits(ICs)shouldbeconsideredsensitiveto electrostaticdischarge(ESD.)ESDdamagecanoccurwhenthereisadifferenceinchargebetweenobjects. ProtectagainstESDdamagebyequalizingthechargesothatthemachine,thepart,theworkmat,andthe personhandlingthepartareallatthesamecharge.

Notes:

1.Useproduct-specicESDprocedureswhentheyexceedtherequirementsnotedhere.

Chapter1.Safetyinformation3

2.MakesurethattheESDprotectivedevicesyouusehavebeencertied(ISO9000)asfullyeffective.

WhenhandlingESD-sensitiveparts:

•Keepthepartsinprotectivepackagesuntiltheyareinsertedintotheproduct.

•Avoidcontactwithotherpeople.

•Wearagroundedwriststrapagainstyourskintoeliminatestaticonyourbody.

•Preventthepartfromtouchingyourclothing.Mostclothingisinsulativeandretainsachargeevenwhen youarewearingawriststrap.

•Useagroundedworkmattoprovideastatic-freeworksurface.Thematisespeciallyusefulwhen handlingESD-sensitivedevices.

•Selectagroundingsystem,suchasthoselistedbelow,toprovideprotectionthatmeetsthespecic servicerequirement.
