一, lub peev xwm ntawm LED Offic Circuit Court board yog puas
Qhov tsis ua hauj lwm tshwm sim los ntawm capacitor kev puas yog qhov siab tshaj plaws hauv cov khoom siv hluav taws xob, tshwj xeeb tshaj yog kev puas tsuaj electrolytic capacitor. Capacitor kev puas tsuaj yog manifested li: 1. Txo qhov muaj peev xwm; 2. Ua tiav lub peev xwm; 3. So; 4. Luv Circuit Court.
二, Kuj puas tsuaj
Nws yog ib txwm pom pom ntau cov pib tshiab fidgeting nrog resistors thaum kho cov boardcuit Coursor laug, txawm hais tias symerling lossis soldering. Qhov tseeb, nrog kev yooj yim dua, tsuav koj nkag siab qhov kev puas tsuaj ntawm resistors, koj tsis tas yuav txhawj ntau dhau. Kev tawm tsam yog cov feem ntau cov khoom siv hauv cov khoom siv hluav taws xob, tab sis nws tsis yog cov khoom tivthaiv nrog kev puas tsuaj ntau tshaj plaws. Kev puas tsuaj puas yog feem ntau hauv kev qhib cov voj voog, nrog ntxiv qhov tseem ceeb yog qhov tseem ceeb thiab txo cov nqi tsis tshua muaj nuj nqis. Hom Hom muaj xws li carbon farpors, hlau yeeb yaj kiab tsim tawm, hlau cov txuj ci tsim, thiab cov khoom siv fur resors. Peb tuaj yeem pom thawj zaug yog tias muaj cov cim ntawm kev hlawv dub ntawm qhov qis tiv taus ntawm Circuit Coiles. Raws li cov yam ntxwv ntawm feem ntau qhib cov voj voog lossis kev ua kom muaj kev tsis kam, peb tuaj yeem siv qhov tsis kam yooj yim, peb tuaj yeem siv qhov tseem ceeb ntawm ob lub siab tiv taus ntawm Circuit Court Board. Yog tias ntsuas tus nqi tsis tshua muaj nuj nqi ntau dua li cov neeg muaj peev xwm ua ntej muaj peev xwm ua ntej lub capacter), yog tias ntsuas qhov txiaj ntsig me me (nws yuav tsum tau txais kev ntsuas tus nqi tsawg dua li cov neeg tsis tshua muaj nuj nqis, nws feem ntau tsis quav ntsej. Nyob rau hauv txoj kev no, txhua tus resistor ntawm Circuit Cour raug ntsuas ib zaug, thiab txawm tias koj ua yuam kev tua ib txhiab, koj yuav tsis nco ib txhiab, koj yuav tsis plam ib tus neeg tiv thaiv.
, Ib txoj hauv kev rau kev txiav txim siab ua haujlwm zoo tshaj plaws ua haujlwm
Cov yam ntxwv muaj cov yam ntxwv ntawm "virtual luv luv" thiab "kev sib tsoo virtual", uas yog qhov muaj txiaj ntsig heev rau kev ua haujlwm tawm cov kab ua haujlwm zoo tshaj plaws. Txhawm rau kom paub tseeb tias cov ntawv thov tawm, ua haujlwm tshaj tawm yuav tsum ua haujlwm hauv lub voj kaw (tsis zoo tawm tswv yim). Yog tias tsis muaj cov lus qhia tsis zoo, cov ua haujlwm zoo tshaj plaws hauv qab qhib-lub voj ua kom nrov ua piv. Yog tias koj xav txiav txim siab qhov ua tau zoo ntawm lub cuab yeej, koj yuav tsum xub paub qhov txawv ntawm seb cov cuab yeej siv puas tau siv raws li kev sib piv lossis piv rau hauv Circuit Court. Raws li lub hauv paus ntsiab lus ntawm Amplifier virtual luv, uas yog hais tawm cov tswv yim ua haujlwm zoo, yog tias muaj qhov sib txawv, nws tseem nyob ntawm theem ntawm MV. Ntawm chav kawm, hauv qee qhov kev hloov siab tshiab tawm ntawm cov hluav taws xob ntau muaj qhov cuam tshuam me me ntawm kev ntsuas voltage, tab sis feem ntau nws tsis tshaj 0.2V. Yog tias muaj qhov sib txawv ntawm 0.5v lossis ntau dua, lub suab nrov tshaj plaws yuav tsis ntseeg! Yog tias cov cuab yeej siv tau siv los ua kev sib piv, nws raug tso cai kom muaj cov tswv yim tsis sib xws hauv tib txoj kev coj thiab rov qab cov lus qhia. Yog hais tias tib voltage loj dua li rov qab voltage, cov zis voltage nyob ze rau tus nqi zoo tshaj plaws; Yog hais tias tib voltage
, Ib qho lus qhia rau kev sim cov khoom siv smt nrog tus multimeter
Qee SMD Cheebtsam yog qhov me me heev, ua rau nws tsis yooj yim siv cov kev txwv tsis pub lwm yam kev sim thiab saib xyuas. Firstly, lawv tuaj yeem yooj yim ua rau muaj cov voj voog luv luv, thiab qhov thib ob, nws tsis yooj yim rau cov laug cam coated nrog rwb thaiv tsev los sib chwv cov pins. Ntawm no yog txheej txheem yooj yim uas yuav coj ntau qhov yooj yim los kuaj. Siv ob qho ntawm cov xaim lav me tshaj plaws, (sib nqus kev lag luam kev tswj hwm kev siv thev naus laus zis) thiab muab lawv kom nruj rau cov cwj mem multimately. Tom qab ntawd, nqa cov hlau tooj liab nyias los ntawm ntau cov hlua sib xyaw, khi tus cwj mem thiab xaws rab koob ua ke nrog cov xov tooj liab tooj liab, thiab siv cov tawv ncauj kom khov kho. Txoj kev no, thaum ntsuas cov tshuab sib txuas nrog lub taub hau me me, tsis muaj kev pheej hmoo ntev dua, thiab cov ntxig txuas ncaj qha, tshem tawm cov kev xav tau thab cov yeeb yaj kiab.
, Txij Nkawm Txoj Kev Txij Nkawm rau cov Circuit Court tsis raug ntawm Circuit Court Board Cov Khoom Siv Hluav Taws Xob
Nyob rau hauv Circuit Court Board tu tsev saib xyuas, yog tias muaj luv nqi hluav taws xob rau ib qhoKev pab fais fab, Nws yog feem ntau cov kev txhaum ntau tshaj plaws, vim tias ntau cov cuab yeej sib koom ua ke rau cov khoom siv hluav taws xob, thiab txhua lub cuab yeej siv lub zog hluav taws xob no. Yog tias tsis muaj ntau cov khoom siv nyob rau ntawm lub rooj tsavxwm, siv "hoe lub ntiaj teb" txoj kev tuaj yeem pom lub sijhawm luv luv. Yog tias muaj ntau feem ntau, txawm hais tias lub "hoe lub ntiaj teb" tuaj yeem hoe tus mob yog nyob ntawm hmoov zoo. Ntawm no yog ib txoj kev pom zoo uas ua haujlwm zoo. Los ntawm kev siv cov qauv no, koj tuaj yeem tau txais ob zaug tshwm sim nrog ib nrab ntawm lub dag zog thiab feem ntau sai nrhiav qhov txhaum cai. Yuav tsum muaj lub zog hluav taws xob nrog kho cov hluav taws xob thiab tam sim no, nrog lub voltage ntawm 0-30V thiab tam sim no ntawm 0-3A. Qhov hluav taws xob hluav taws xob no tsis kim thiab tus nqi nyob ib ncig ntawm 300 yuan. Kho cov qhib hluav taws xob voltage mus rau theem ntawm lub cuab yeejKev pab fais fab. Ua ntej, kho qhov tam sim no rau qhov tsawg kawg nkaus. Siv cov hluav taws xob no rau lub zog hluav taws xob cov ntsiab lus ntawm cov Circuit Court, xws li 5V thiab 0V cov lus xaus ntawm 74 series nti. Ua raws li cov qib ntawm lub luvfab, maj mam nce qhov tam sim no. Kov lub cuab yeej nrog koj txhais tes. Thaum qee cov cuab yeej siv hluav taws kub ua kom kub heev, nws feem ntau yog feem kev sib cav sib haum. Koj tuaj yeem tshem tawm nws rau kev ntsuas ntxiv thiab kev pom zoo. Tau kawg, lub voltage thaum lub sijhawm ua haujlwm yuav tsum tsis pub tshaj qhov chaw ua hauj lwm ntawm cov cuab yeej, thiab nws yuav tsum tsis txhob thim rov qab, nws yuav hlawv lwm cov khoom siv zoo.
六, ib lub roj hmab me los daws cov teeb meem loj
Tus naj npawb ntawm cov laug cam tau siv hauv kev tswj kev lag luam nce zuj zus, thiab ntau lub rooj zaum siv tus qauv ntawm kev ntxig kub ntiv tes mus rau hauv cov pob. Vim yog lub chaw muaj plua plav muaj plua plav, uas yog plua plav, noo, thiab corrosive, nws yooj yim rau cov laug cam kom muaj kev sib tiv thaiv tsis zoo. Ntau tus phooj ywg yuav daws qhov teeb meem los ntawm hloov cov laug cam, tab sis tus nqi ntawm cov laug cam yog ntau heev, tshwj xeeb tshaj yog rau qee cov txiag hluav taws. Qhov tseeb, txhua tus tuaj yeem siv tus lwv kom pheej so cov av ntawm cov ntiv tes kub ob peb zaug, ntxuav nws, thiab tom qab ntawd sim lub tshuab dua. Tej zaum qhov teeb meem yuav daws! Tus txheej txheem yog yooj yim thiab siv tau.
, Kev tshuaj ntsuam xyuas hluav taws xob ua txhaum nrog lub sijhawm zoo thiab tsis zoo
Nyob rau hauv cov nqe lus ntawm qhov tshwm sim, ntau yam hluav taws ua txhaum nrog lub sijhawm zoo thiab tsis zoo yuav suav nrog cov xwm txheej hauv qab no:
1. Cov neeg sib chwv tsis zoo ntawm lub rooj tsavxwm thiab qhov, tsis sib txuas thaum lub cav hluav taws xob tawg, tsis muaj kev sib raug zoo ntawm lub Cheebtsam no txhua yam rau cov pawg no;
2. Rau cov kab ncig digital, malfunctions tsuas yog tshwm sim raws cov mob tshwj xeeb vim yog cov cim kev cuam tshuam. Nws yog qhov ua tau tias kev cuam tshuam ntau dhau tau cuam tshuam cov txheej txheem tswj hwm lossis ua rau nws muaj peev xwm ua yuam kev, thiab tseem muaj kev ua yuam kev ntawm cov muaj peev xwm tiv thaiv kev cuam tshuam thiab kev ua phem;
3. Tsis zoo thermal ruaj khov ntawm cov txheej txheem los ntawm ntau cov kev tswj hwm kev saib xyuas, ua haujlwm ntawm cov khoom siv hluav taws xob, ua haujlwm ntawm cov khoom siv hluav taws xob, ntawm cov khoom siv hluav taws xob ntawm thawj lub zog electrolytic
4. Muaj noo noo, plua plav zuj zus, thiab lwm yam ntawm Circuit Court Board. Kev ya raws thiab plua plav yuav ua hluav taws xob nrog cov nyhuv tiv thaiv, thiab tus nqi resistance yuav hloov pauv thaum lub zog nthuav dav. Qhov kev tiv thaiv no muaj cov nyhuv parallel nrog lwm cov khoom siv. Yog tias cov nyhuv no muaj zog, Circuit Coursers yuav hloov pauv, ua rau muaj kev ua txhaum;
5. Software kuj yog ib qho ntawm cov xwm txheej los txiav txim siab. Coob tus tsis muaj nyob hauv Circuit Court raug kho siv software, thiab cov npoo ntawm qee qhov tsis muaj nqis qis, uas yog qhov tseem ceeb dhau los. Thaum lub tshuab ua haujlwm ua haujlwm tau raws li qhov laj thawj rau lub software los txiav txim qhov txhaum, lub tswb yuav tshwm sim.
