Somesemiconductor(“solidstate”)devicesareeasilydamagedbystaticelectricity. SuchcomponentsarecalledElectrostaticallySensitiveDevices(ESDs). Examplesincludeintegratedcircuitsandsomeeld-effecttransistors. Thefollowingtechniqueswillreducetheoccurrenceofcomponentdamagecausedbystaticelectricity:

1)Immediatelybeforehandlinganysemiconductorcomponentsorassemblies,draintheelectrostaticchargefromyour bodybytouchingaknownearthground.Alternatively,wearadischargingwrist-strapdevice.(Besuretoremoveit priortoapplyingpower–thisisanelectricshockprecaution.)

2)AfterremovinganESD-equippedassembly ,placeitonaconductivesurfacesuchasaluminumfoiltoprevent accumulationofelectrostaticcharge.

3)Donotusefreon-propelledchemicals.ThesecangenerateelectricalchargesthatdamageESDs.

4)Useonlyagrounded-tipsolderingironwhensolderingorunsolderingESDs.

5)Useonlyananti-staticsolderremovaldevice.Manysolderremovaldevicesarenotratedas“anti-static”(thesecan accumulatesufcientelectricalchargetodamageESDs).

6)DonotremoveareplacementESDfromitsprotectivepackageuntilyouarereadytoinstallit. MostreplacementESDsarepackagedwithleadsthatareelectricallyshortedtogetherbyconductivefoam,aluminum foilorotherconductivematerials.

7)ImmediatelybeforeremovingtheprotectivematerialfromtheleadsofareplacementESD,touchtheprotectivematerial tothechassisorcircuitassemblyintowhichthedevicewillbeinstalled.
