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
