Anycomputerpartcontainingtransistorsorintegratedcircuits(ICs)shouldbe
consideredsensitivetoelectrostaticdischarge(ESD).ESDdamagecanoccur
whenthereisadifferenceinchargebetweenobjects.ProtectagainstESDdamage
byequalizingthechargesothatthemachine,thepart,theworkmat,andthe
personhandlingthepartareallatthesamecharge.
WhenhandlingESD‐sensitiveparts:
• Keepthepartsinprotectivepackagesuntiltheyareinsertedintotheproduct.
• Avoidcontactwithotherpeople.
• Wearagroundedwriststrapagainstyourskintoeliminatestaticonyour
body.
• Preventthepartfromtouchingyourclothing.Mostclothingisinsulativeand
retainsachargeevenwhenyouarewearingawriststrap.
• Usetheblacksideofagroundedworkmattoprovideastatic‐freework
surface.ThematisespeciallyusefulwhenhandlingESD‐sensitivedevices.
• Selectagroundingsystem,suchasthoselistedbelow,toprovideprotection
thatmeetsthespecificservicerequirement.
– AttachtheESDgroundcliptoanyframeground,groundbraid,orgreen‐
wireground.
– Whenworkingonadouble‐insulatedorbattery‐operatedsystem,usean
ESDcommongroundorreferencepoint.Youcanusecoaxorconnector‐
outsideshellsonthesesystems.
– Usetheroundgroundprongoftheacplugonac‐operatedcomputers.
Electricalgroundingofthecomputerisrequiredforoperatorsafetyandcorrect
systemfunction.Propergroundingoftheelectricaloutletcanbeverifiedbya
certifiedelectrician.

Notes:
1. Useproduct‐specificESDprocedureswhentheyexceedthe
requirementsnotedhere.
2. MakesurethattheESDprotectivedevicesyouusehavebeencertified
(ISO9000)asfullyeffective.
Notes:
TheuseofagroundingsystemtoguardagainstESDdamageisdesirablebut
notnecessary.
