1.1. GENERALGUIDELINES

1. Whenservicing,observetheoriginalleaddress.Ifashortcircuitisfound,replaceallpartswhichhavebeenoverheatedor damagedbytheshortcircuit.

2. Afterservicing,seetoitthatalltheprotectivedevicessuchasinsulationbarriers,insulationpapersshieldsareproperly installed.

3. Afterservicing,carryoutthefollowingleakagecurrentcheckstopreventthecustomerfrombeingexposedtoshockhazards.

1.1.1. LEAKAGECURRENTCOLDCHECK

2 PreventionofElectroStaticDischarge(ESD)to

ElectrostaticallySensitive(ES)Devices

Somesemiconductor(solidstate)devicescanbedamagedeasilybystaticelectricity.Suchcomponentscommonlyarecalled ElectrostaticallySensitive(ES)Devices.ExamplesoftypicalESdevicesareintegratedcircuitsandsomefield-effecttransistorsand semiconductor"chip"components.Thefollowingtechniquesshouldbeusedtohelpreducetheincidenceofcomponentdamage causedbyelectrostaticdischarge(ESD).

1. Immediatelybeforehandlinganysemiconductorcomponentorsemiconductor-equippedassembly,drainoffanyESDonyour bodybytouchingaknownearthground.Alternatively,obtainandwearacommerciallyavailabledischargingESDwriststrap, whichshouldberemovedforpotentialshockreasonspriortoapplyingpowertotheunitundertest.

2. AfterremovinganelectricalassemblyequippedwithESdevices,placetheassemblyonaconductivesurfacesuchas aluminumfoil,topreventelectrostaticchargebuilduporexposureoftheassembly.

3. Useonlyagrounded-tipsolderingirontosolderorunsolderESdevices.

4. Useonlyananti-staticsolderremovaldevice.Somesolderremovaldevicesnotclassifiedas"anti-static(ESDprotected)"can generateelectricalchargesufficienttodamageESdevices.

5. Donotusefreon-propelledchemicals.ThesecangenerateelectricalchargessufficienttodamageESdevices.

6. DonotremoveareplacementESdevicefromitsprotectivepackageuntilimmediatelybeforeyouarereadytoinstallit.(Most replacementESdevicesarepackagedwithleadselectricallyshortedtogetherbyconductivefoam,aluminumfoilorcomparable conductivematerial).

7. ImmediatelybeforeremovingtheprotectivematerialfromtheleadsofareplacementESdevice,touchtheprotectivematerial tothechassisorcircuitassemblyintowhichthedevicewillbeinstalled.
