Handlingdevicesthataresensitivetoelectrostaticdischarge

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

Notes:

1.Useproduct-specificESDprocedureswhentheyexceedtherequirementsnotedhere.

2.MakesurethattheESDprotectivedevicesyouusehavebeencertified(ISO9000)asfullyeffective.

WhenhandlingESD-sensitiveparts:

•Keepthepartsinprotectivepackagesuntiltheyareinsertedintotheproduct.

•Avoidcontactwithotherpeople.

•Wearagroundedwriststrapagainstyourskintoeliminatestaticonyourbody.

•Preventthepartfromtouchingyourclothing.Mostclothingisinsulativeandretainsachargeeven
