Handling

SMDresistorsandcapacitorsarewidelyusedintheCyrusrangeofproducts.Whenhandling

SMDcomponents,certainprecautionsshouldbeobserved‐

HandlingSMDresistorsandcapacitors

 AlwaysstoreSMDcomponentsintheiroriginalpackagingorinacooldryenvironment.

 AlwayshandleSMDresistorsandcapacitorswithtweezersoravacuumpencil.

 NeverhandleSMDresistorsandcapacitorswithfingers.

 HoldtheSMDcomponentbythebody,notbytheends.

 DonotuseSMDresistorsorcapacitorsiftheendsaredirtyordiscoloured.

 DonotuseSMDresistorsorcapacitorsiftheyhavebeendroppedonthefloor‐ theymay

beinternallydamaged.

 Alwaysusereplacementcomponentsofthecorrectsizeandshape.SMDcomponentsare

availableinmanydifferentpackages.Wherepossible,orderoriginalpartsfromCyrus.

HandlingSMDICs

 Alwaysstorethesecomponentsintheiroriginalpackagingorinacooldryenvironment.

 AlwayshandleSMDtransistorsandICswithtweezersoravacuumpencil.

 NeverhandleSMDtransistorsandICswithfingers.

 Ensurethattheconnectionpinsoflargermulti‐pinICsarenotdeformedordamaged

beforefitting.

MeasuringcircuitswithSMDcapacitorsandresistors

 Avoidusingsharp,pointedprobesdirectlyonthecomponentendcaps.

 MeasurevoltagesfromthePCBpadnexttothecomponent.

Staticprecautions

SMDcomponents,particularlyICs,maybedamagedbythestaticlevelspresentinthe

workshop.Damagecausedbystaticmaynotimmediatelycausecomponentfailurebutcould

causepartialdamageandapossiblefailureinthefuture.ObservingthesesimpleSMD

precautionswillavoidproductfailuresrelatedtostaticdamage‐

 Alwayswearagroundedwristbandwhenreplacinganyelectroniccomponents.

 Alwaysstorecomponentsintheiroriginalpackagingorconductiveplasticbags.

 Neverstorecomponentsinplastictraysorbagswithoutprotection.

Soldering/desolderingSMDcomponents

 Neverre‐useoldSMDcomponentsafterde‐soldering!

 Alwaysapplysolderheatdirectlytothecontactarea.Avoidover‐heatingadjacent

components.

 AlwaysrepairSMDPCBswiththecorrecttools.SMDcomponentscanonlybereplacedwith

ahotairpencilorsolderingirondesignedforSMDcomponents,preferablywith

temperaturecontrol.

 Keepthesolderingtemperatureaslowaspossible.370ºCisrecommendedforLeadfree
