Cov hlau kuaj liab yog hauv av, cov pins hauv lub voj voog liab yog txhua qhov chaw, thiab cov ncej tsis zoo ntawm cov capacitors yog txhua qhov chaw. Muab cov xim dub rau ntawm tus pin IC los ntsuas, thiab tom qab ntawd tus multimeter yuav tso saib tus nqi diode, thiab txiav txim siab qhov zoo ntawm IC raws li tus nqi diode. Tus nqi zoo yog dab tsi? Nws nyob ntawm kev paub. Txawm hais tias koj muaj lub motherboard thiab ua qhov sib piv ntsuas.
Yuav ua li cas thiaj nrhiav tau qhov txhaum
1 Saib cov xwm txheej ntawm cov khoom
Tau txais lub rooj tsav xwm tsis zoo, ua ntej saib seb lub rooj tsav xwm Circuit Court puas muaj kev puas tsuaj, xws li electrolytic capacitor burnout thiab o, resistor burnout, thiab lub hwj chim ntaus ntawv burnout.
2 Saib ntawm qhov soldering ntawm lub rooj tsav xwm Circuit Court
Piv txwv li, txawm tias lub rooj tsav xwm luam tawm yog deformed lossis warped; seb cov pob qij txha puas poob los yog pom tseeb tsis muaj zog soldered; seb tooj liab clad daim tawv nqaij ntawm lub rooj tsav xwm Circuit Court yog warped, hlawv thiab tig dub.
3 Kev soj ntsuam tivthaiv plug-in
Xws li integrated circuits, diodes, circuit board fais fab mov transformers, thiab lwm yam yog tso kom raug.
4 Kev sim yooj yim tiv taus\ muaj peev xwm\ induction
Siv multimeter los ua ib qho kev sim yooj yim ntawm cov khoom uas xav tias muaj xws li tsis kam, capacitance, thiab inductance nyob rau hauv ntau yam los ntsuam xyuas seb tus nqi kuj nce, capacitor luv Circuit Court, qhib Circuit Court thiab capacitance hloov, inductance luv Circuit Court thiab qhib Circuit Court.
5 Kev ntsuas hluav taws xob
Tom qab qhov kev soj ntsuam yooj yim thiab kev soj ntsuam tau hais saum toj no, qhov kev ua txhaum tsis tuaj yeem raug tshem tawm, thiab kev ntsuas hluav taws xob tuaj yeem ua tiav. Ua ntej kuaj seb lub hwj chim ntawm lub rooj tsav xwm hauv Circuit Court puas zoo li qub. Xws li seb lub AC fais fab mov ntawm lub rooj tsavxwm Circuit Court yog txawv txav, seb qhov voltage regulator tso zis yog txawv txav, seb lub switching fais fab mov tso zis thiab waveform yog txawv txav, thiab lwm yam.
6 txhuam program
Rau cov programmable Cheebtsam xws li ib-chip microcomputer, DSP, CPLD, thiab lwm yam, koj tuaj yeem txiav txim siab txhuam qhov kev pab cuam dua kom tshem tawm cov kev ua haujlwm tsis zoo los ntawm kev ua haujlwm tsis zoo.
Yuav kho cov kab hluav taws xob li cas?
1 Kev soj ntsuam
Txoj kev no yog intuitive heev. Los ntawm kev soj ntsuam xyuas kom zoo, peb tuaj yeem pom tseeb pom cov kab tawg. Thaum qhov teeb meem no tshwm sim, peb yuav tsum xyuam xim rau cov kev cai thaum lub sij hawm tu thiab tshuaj xyuas kom ntseeg tau tias tsis muaj kev raug mob hnyav ntxiv thaum lub hwj chim qhib. Thaum peb siv txoj kev no, peb yuav tsum tau xyuam xim rau cov teeb meem hauv qab no:
1. Saib xyuas seb lub rooj tsav xwm hauv Circuit Court puas los ntawm tus txiv neej.
2. Ua tib zoo saib xyuas cov khoom muaj feem cuam tshuam ntawm lub rooj tsav xwm hauv Circuit Court, thiab saib xyuas txhua lub capacitor thiab tiv thaiv kom pom tias muaj kev tsaus ntuj. Vim tsis tuaj yeem saib tsis tau, nws tsuas yog ntsuas tau nrog lub ntsuas. Yam tsis zoo yuav tsum tau hloov raws sijhawm.
3.Kev soj ntsuam ntawm lub rooj tsav xwm hauv Circuit Court integrated circuits, xws li CPU, AD thiab lwm yam chips, yuav tsum tau hloov nyob rau hauv lub sij hawm thaum soj ntsuam cov xwm txheej xws li bulging thiab hlawv.
Qhov ua rau ntawm cov teeb meem saum toj no tuaj yeem yog nyob rau tam sim no. Cov tam sim no ntau dhau tuaj yeem ua rau muaj kev kub ntxhov, yog li tshawb xyuas daim duab hluav taws xob cuam tshuam kom pom qhov teeb meem nyob qhov twg.
2. Kev ntsuas zoo li qub
Hauv kev kho vaj huam sib luag hauv Circuit Court, nws yog ib qho nyuaj rau nrhiav tau qee qhov teeb meem los ntawm txoj kev soj ntsuam, tshwj tsis yog nws pom tseeb tias nws tau hlawv lossis deformed. Tab sis feem ntau ntawm cov teeb meem tseem yuav tsum tau ntsuas los ntawm lub voltmeter ua ntej kev txiav txim siab tuaj yeem kos. Circuit board Cheebtsam thiab lwm yam yuav tsum tau kuaj ib tug los ntawm ib tug. Txoj kev kho yuav tsum tau ua raws li cov txheej txheem hauv qab no.
Tshawb xyuas qhov luv luv ntawm cov khoom siv hluav taws xob thiab hauv av thiab xyuas seb yog vim li cas.
Xyuas seb lub diode puas zoo li qub.
Xyuas seb puas muaj ib qho luv luv lossis txawm tias qhib Circuit Court hauv lub capacitor.
Tshawb xyuas lub rooj sib tham hauv Circuit Board-related circuits, thiab kev tiv thaiv thiab lwm yam khoom siv ntsuas.
Peb tuaj yeem siv txoj kev soj ntsuam thiab ntsuas qhov zoo li qub los daws cov teeb meem feem ntau hauv kev saib xyuas lub rooj tsav xwm Circuit Court. Qhov no yog qhov tsis txaus ntseeg, tab sis peb yuav tsum xyuas kom meej tias cov khoom siv hluav taws xob zoo li qub thaum ntsuas thiab tsis muaj kev puas tsuaj ntxiv tuaj yeem tshwm sim.
3 Kev ntsuas online
Txoj kev ntsuas hauv online feem ntau siv los ntawm cov tuam ntxhab. Nws yog ib qho tsim nyog los tsim kom muaj qhov dav dav debugging thiab txij nkawm platform kom yooj yim ntawm kev saib xyuas. Thaum ntsuas nrog txoj kev no, koj yuav tsum ua raws li cov kauj ruam hauv qab no.
Fais fab ntawm lub rooj tsavxwm Circuit Court thiab xyuas seb cov khoom puas yog overheated. Yog tias muaj, txheeb xyuas nws thiab hloov cov khoom cuam tshuam.
Tshawb xyuas lub rooj vag Circuit Court sib raug rau lub rooj tsav xwm Circuit Court, saib seb puas muaj teeb meem nrog lub logic, thiab txiav txim siab seb lub nti yog qhov zoo lossis qhov phem.
Ntsuam xyuas seb qhov tso zis ntawm digital circuit siv lead ua oscillator puas yog qhov qub.
Txoj kev ntsuas hauv online feem ntau yog siv los sib piv ob lub rooj tsav xwm zoo thiab tsis zoo. Los ntawm kev sib piv, qhov teeb meem pom, qhov teeb meem raug daws, thiab kev kho ntawm lub rooj tsav xwm Circuit Court tau ua tiav.
