Yuav ua li cas paub cov kev taw qhia ntawm SMD dodes?

1, nkag siab cov qauv kev yooj yim ntawm SMD diodes
SMD Diodes feem ntau suav nrog ib qho kev sib tshuam nrog ib qho kawg li Anode (zoo electrode) thiab lwm qhov kawg li cathode (tsis zoo electrode). Nyob rau hauv cov nqe lus ntawm ntim, cov tuam ntxhab feem ntau teem qee cov cim lossis cov nta ntawm Diarity rau kev qhia yooj yim thiab kev teeb tsa tau yooj yim.
2, Cim cim txoj kev
Dot Mark: Ntau SMD Dailes muaj ib qho me me lossis daim duab peb sab kos tau luam tawm ntawm ib kawg, uas feem ntau sawv cev rau cathode (tsis zoo ncej). Yog tias tsuas muaj ib qho cim ntawm diode, ces nws yog cathode.
Ribbon or color ring: Some diodes may have a ribbon or color ring on the cathode side, and the color may vary from manufacturer to manufacturer, but the function is the same, used to indicate the cathode.
Tsab ntawv lossis tus lej cim: Qee qhov diodes yuav muaj cov ntawv sau lossis cov lej luam tawm ncaj qha qhia txog kev ua haujlwm polarity lossis tsis ncaj qha qhia nws los ntawm cov khw coding system. Txheeb xyuas cov ntaub ntawv ntawm cov ntaub ntawv muab los ntawm cov khw yog qhov tseem ceeb kom nkag siab cov cim no.
Qhov sib txawv los yog ntug txiav: qee qhov diodes muaj cov khoob me me lossis cov npoo ntawm lub ntim ntug, uas feem ntau kuj yog cov cim ntawm cov cathode.
3, Lub cev kev soj ntsuam txoj kev xav
Cov duab sib txawv: Txawm hais tias feem ntau smd diodes zoo sib xws nyob rau hauv tsos, qee tus qauv yuav qhia polarity los ntawm kev hloov pauv txawv ntawm qhov sib txawv. Piv txwv li, lub cathode kawg tej zaum yuav yog me ntsis dav dav lossis ntev dua.
Tus Pin puab: Txawm hais tias SMD Diodes feem ntau tsis muaj cov pins tsoos, xws li sib txawv me me) muaj qhov sib txawv me me ntawm cov pins no tseem tuaj yeem siv los qhia polarity.
4, siv cov cuab yeej tshaj lij
Motorifyize iav lossis tsom iav: rau diodes nrog rau kev sib tw lossis lub iav loj tuaj yeem ua kom pom cov ntsiab lus thiab pab pom cov cim kom meej meej.
Polarity Tester: Qhov no yog cov cuab yeej tshwj xeeb yog tsim los sim cov polarity ntawm cov hluav taws xob sib xyaw. Los ntawm tsuas yog kov cov kev sojntsuam ntawm tester rau ob qho kawg ntawm Diode, tus teser tuaj yeem tso tawm cov polarity ntawm Diode.
Ntau yam: txawm hais tias muaj ntau siv los ntsuas kev ntsuas, tam sim no, nws txoj kev sib tw, nws kuj tseem tuaj yeem ntsuas qhov ntsuas los ntawm kev ntsuas mus rau tom ntej. Txawm li cas los xij, cov qauv no yuav tsum muaj qee yam kev paub dhau los thiab kev txawj.
5, Cov Ntaub Ntawv Cov Chaw Tsim Tshuaj
Qhov kev ncaj qha ncaj qha thiab muaj tseeb yog xa mus rau cov ntaub ntawv ntawm phau ntawv lossis daim ntawv tshwj xeeb muab los ntawm cov khw. Cov ntaub ntawv no feem ntau suav nrog cov ncauj lus kom ntxaws xws li lub ntim loj ntawm cov lus qhia, thiab cov yam ntxwv hluav taws xob, kom paub tseeb tias muaj cov ntaub ntawv tshiab ntawm txhais tes rau kev siv sai sai thaum xav tau.
6, kev ceev faj hauv kev xyaum
Lub teeb thiab lub kaum ntse ntse: kom paub tseeb lub teeb pom kev zoo hauv chaw ua haujlwm thiab saib cov diode los ntawm cov ces kaum sib txawv kom ntes cov ntsiab lus ntau dua.
Tswj kev nyiam huv: Thaum kev tuav thiab txhim kho thaj chaw ua haujlwm, khaws cia rau nws tus kheej xws li cov roj thiab plua plav muaj kev cuam tshuam rau kev txheeb xyuas thiab cov khoom siv installation.
Cov ntaubntawv povthawj thiab cim: Rau cov kev siv hnyav dua
Ceev faj hauv kev ua haujlwm: Vim tias qhov me me ntawm SMD DIODES, kev saib xyuas tshwj xeeb yuav tsum tau noj thaum ua haujlwm kom tsis txhob puas tsuaj lossis poob.
