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

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

3)UseonlyagroundedtipsolderingirontosolderordesolderESDs.

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