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 tau xyuam xim rau cov kev cai thaum lub sij hawm tu thiab kev soj ntsuam xyuas kom tsis txhob 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.
