Handlingdevicesthataresensitivetoelectrostaticdischarge

Anycomputerpartcontainingtransistorsorintegratedcircuits(ICs)shouldbeconsideredsensitiveto electrostaticdischarge(ESD).ESDdamagecanoccurwhenthereisadifferenceinchargebetweenobjects. ProtectagainstESDdamagebyequalizingthechargesothatthemachine,thepart,theworkmat,andthe personhandlingthepartareallatthesamecharge.
Notes:
1.Useproduct-specicESDprocedureswhentheyexceedtherequirementsnotedhere.
2.EnsurethattheESDprotectivedevicesyouusehavebeencertied(ISO9000)asfullyeffective.
Chapter1.Safetyinformation3
WhenhandlingESD-sensitiveparts:
•Keepthepartsinprotectivepackagesuntiltheyareinsertedintotheproduct.
•Avoidcontactwithotherpeople.
•Wearagroundedwriststrapagainstyourskintoeliminatestaticonyourbody.
•Preventthepartfromtouchingyourclothing.Mostclothingisinsulativeandretainsachargeevenwhen youarewearingawriststrap.
