1.3.ESDprecautions

Certainsemiconductordevicescanbeeasilydamagedbystaticelectricity.Suchcomponentsarecommonlycalled “ElectrostaticallySensitive(ES)Devices”orESDs.ExamplesoftypicalESDsare:integratedcircuits,someeldeffect transistors,andsemiconductor“chip”components.Thetechniquesoutlinedbelowshouldbefollowedtohelpreducethe incidenceofcomponentdamagecausedbystaticelectricity.

CAUTION

Besurenopowerisappliedtothechassisorcircuit,andobserveallothersafetyprecautions.

1)Immediatelybeforehandlingasemiconductorcomponentorsemiconductor-equippedassembly,drainoffany electrostaticchargeonyourbodybytouchingaknownearthground.Alternatively,employacommerciallyavailable wriststrapdevice,whichshouldberemovedforyourpersonalsafetyreasonspriortoapplyingpowertotheunit undertest.

2)AfterremovinganelectricalassemblyequippedwithESDs,placetheassemblyonaconductivesurface,suchas aluminumorcopperfoil,orconductivefoam,topreventelectrostaticchargebuildupinthevicinityoftheassembly.

3)UseonlyagroundedtipsolderingirontosolderordesolderESDs.

4)Useonlyan“anti-static”solderremovaldevice.Somesolderremovaldevicesnotclassiedas“anti-static”can generateelectricalchargessufcienttodamageESDs.
