一 capac Ubushobozi bwikibaho cyerekana LED cyangiritse
Kunanirwa guterwa no kwangirika kwa capacitori nicyo kinini mubikoresho bya elegitoroniki, cyane cyane kwangirika kwa capacitori ya electrolytike.Kwangirika kwa capacitor bigaragarira nka: 1. kugabanya ubushobozi;2. Gutakaza ubushobozi bwuzuye;3. Kumeneka;4. Inzira ngufi.
二 Kwangirika
Birasanzwe kubona benshi batangiye guhinda umushyitsi mugihe basana imbaho zumuzunguruko, gusenya cyangwa kugurisha.Mubyukuri, hamwe no gusana byinshi, mugihe usobanukiwe ibyangiritse biranga abarwanya, ntugomba guhangayika cyane.Kurwanya nikintu kinini mubikoresho byamashanyarazi, ariko ntabwo aricyo kintu gifite igipimo cyangiritse cyane.Kwangirika kwangirika bikunze kugaragara mumuzunguruko ufunguye, hamwe no kongera indangagaciro zo kurwanya ni gake kandi kugabanuka kwindangagaciro bikaba gake.Ubwoko busanzwe burimo firime ya karubone, ibyuma birwanya ibyuma, ibyuma bikomeretsa insinga, hamwe na fuse birwanya.Turashobora kubanza kureba niba hari ibimenyetso byo gutwika umukara kumurwanya muke urwanya ikibaho cyumuzunguruko.Dufatiye ku biranga imiyoboro myinshi ifunguye cyangwa kwiyongera kwinshi iyo kurwanya kwangiritse, kimwe nuburyo bwo guhangana cyane kwangirika byoroshye, turashobora gukoresha multimeter kugirango dupime byimazeyo indangagaciro zurwanya kumpande zombi zurwanya rukomeye kuri ikibaho cyumuzunguruko.Niba igipimo cyo guhangana cyapimwe kirenze agaciro k’izina ryo kurwanya, Niba byanze bikunze byangiritse (hagomba kumenyekana gutegereza kugeza igihe agaciro kerekana ko gahagaze mbere yo gufata umwanzuro, kuko hashobora kubaho uburyo bwo kwishyuza no gusohora bujyanye na capacitor ibice mumuzunguruko), niba ibipimo byapimwe byapimwe ari bito kurenza agaciro kangana nizina, muri rusange birengagizwa.Muri ubu buryo, buri résistoriste ku kibaho cyumuzingi gipimwa rimwe, kandi niyo wica kubwimpanuka igihumbi, ntuzabura na résistoriste imwe.
三 Method Uburyo bwo gusuzuma ubuziranenge bwibikorwa byongera imbaraga
Amplifiers zifite ibiranga "virtual short" na "break break", bifite akamaro kanini mu gusesengura umurongo ukora ibikorwa bya amplifier.Kugirango umenye neza umurongo, amplifier ikora igomba gukora mumuzinga ufunze (ibitekerezo bibi).Niba nta bitekerezo bibi, amplifier ikora munsi yugurura-gufungura ihinduka igereranya.Niba ushaka kumenya ubuziranenge bwigikoresho, ugomba kubanza gutandukanya niba igikoresho gikoreshwa nka amplifier cyangwa igereranya mukuzunguruka.Ukurikije ihame rya amplifier virtual short, nukuvuga, niba amplifier ikora ikora neza, voltage kumurongo umwe winjiza hamwe ninyuma yinjiza igomba kuba ingana, niyo haba hari itandukaniro, iracyari kurwego rwa mv .Byumvikane ko, mubice bimwe byinjira byinjira, inzitizi yimbere ya multimeter irashobora kugira ingaruka nkeya mugupima voltage, ariko mubisanzwe ntabwo irenga 0.2V.Niba hari itandukaniro rya 0.5V cyangwa irenga, amplifier ntizabura kunanirwa!Niba igikoresho cyakoreshejwe nkugereranya, biremewe kugira ibyinjira byinjira bitaringaniye mubyerekezo kimwe no guhindukira.Niba voltage imwe iruta voltage ihindagurika, ibisohoka voltage yegereye agaciro keza keza;Niba voltage imwe
四 Inama yo kugerageza ibice bya SMT hamwe na multimeter
Ibice bimwe na bimwe bya SMD ni bito cyane, bigatuma bitoroha gukoresha progaramu isanzwe ya multimeter mugupima no kuyitaho.Ubwa mbere, birashobora guteza byoroshye imiyoboro migufi, icya kabiri, ntibyoroshye ko imbaho zumuzunguruko zometseho insulasiyo zihura nibice byicyuma cyibikoresho.Hano hari uburyo bworoshye buzazana byinshi byoroshye mugupima.Fata bibiri mu nshinge ntoya zidoda, (Inkingi Yimbaraga Zigenzura Inganda Zifata Ikoranabuhanga) hanyuma ubishyire neza ku ikaramu ya metero nyinshi.Noneho, fata umugozi muto wumuringa uva mumigozi myinshi, uhambire ikaramu hamwe nurushinge rwo kudoda hamwe numuringa mwiza wumuringa, hanyuma ubigurishe neza.Ubu buryo, iyo upimye ibice bya SMT hamwe na stylus ifite inshinge ntoya, ntakibazo gishobora kuba cyumuzunguruko mugufi, kandi inshinge y'urushinge irashobora gutobora igifuniko cyiziritse kandi igahita ikubita ibice byingenzi, bikuraho gukenera guhangayikishwa no gukuramo firime.
五 Method Uburyo bwo Kubungabunga Uburyo Bugufi Buzunguruka Amakosa Yumuzunguruko Rusange Amashanyarazi
Mububiko bwumuzunguruko, niba hari uruziga rugufi kuri rusangeamashanyarazi, akenshi ni amakosa akunze kugaragara, kubera ko ibikoresho byinshi bisangiye amashanyarazi amwe, kandi buri gikoresho gikoresha aya mashanyarazi gikekwa ko kizunguruka gito.Niba nta bice byinshi biri ku kibaho, ukoresheje uburyo "hoe isi" amaherezo ushobora kubona aho bigarukira.Niba haribintu byinshi cyane, niba "hoe isi" ishobora guhuza imiterere biterwa namahirwe.Hano hari uburyo busabwa bukora neza.Ukoresheje ubu buryo, urashobora kubona ibisubizo kabiri hamwe nimbaraga zimbaraga kandi akenshi uhita ubona aho amakosa ari.Hagomba kubaho amashanyarazi hamwe na voltage ishobora guhinduka hamwe nubu, hamwe na voltage ya 0-30V hamwe numuyoboro wa 0-3A.Amashanyarazi ntabwo ahenze kandi agura hafi 300.Hindura umuyaga ufunguye uruziga kurwego rwibikoreshoamashanyarazivoltage.Ubwa mbere, hindura ikigezweho kugeza byibuze.Koresha iyi voltage kumashanyarazi yumuriro wumurongo wumuzunguruko, nka 5V na 0V ya terefone ya 74 ya chip.Ukurikije urwego rwumuzunguruko mugufi, buhoro buhoro wongere ikigezweho.Kora ku gikoresho ukoresheje ukuboko kwawe.Iyo igikoresho runaka gishyushye cyane, akenshi ni ibintu byangiritse.Urashobora kuyikuraho kugirango irusheho gupimwa no kwemezwa.Birumvikana ko voltage mugihe ikora ntigomba kurenza imbaraga zumurimo wigikoresho, kandi ntigomba guhinduka, bitabaye ibyo izatwika ibindi bikoresho byiza.
Rubber rubber reberi ntoya kugirango ikemure ibibazo bikomeye
Umubare wibibaho bikoreshwa mugucunga inganda biriyongera, kandi imbaho nyinshi zikoresha uburyo bwo kwinjiza intoki za zahabu ahantu.Bitewe n’ibidukikije bikabije by’inganda, birimo umukungugu, ubushuhe, kandi byangirika, biroroshye ko imbaho zigira amakosa yo guhura.Inshuti nyinshi zishobora kuba zarakemuye ikibazo mugusimbuza imbaho, ariko ikiguzi cyo kugura imbaho ni kinini cyane cyane kubibaho bimwe bitumizwa mu mahanga.Mubyukuri, buriwese arashobora gukoresha gusiba kugirango ahanagure inshuro nyinshi umwanda kurutoki rwa zahabu inshuro nke, awusukure, hanyuma wongere ugerageze imashini.Ahari ikibazo kizakemuka!Uburyo buroroshye kandi bufatika.
、 Gusesengura amakosa yumuriro hamwe nigihe cyiza kandi kibi
Kubijyanye nibishoboka, amakosa atandukanye y'amashanyarazi hamwe nibihe byiza nibibi ashobora gushiramo ibihe bikurikira:
1. Guhuza nabi hagati yubuyobozi nu mwanya, kunanirwa guhuza mugihe umugozi wacitse imbere, guhuza nabi hagati yicyuma na terefone, no kugurisha nabi ibice byose biri muriki cyiciro;
2. Kumuzunguruko wa digitale, imikorere mibi ibaho gusa mubihe byihariye kubera kubangamira ibimenyetso.Birashoboka ko kwivanga gukabije byagize ingaruka kuri sisitemu yo kugenzura bikayitera gukora amakosa, kandi hari nimpinduka mubice bigize ibice byumuntu cyangwa ibipimo rusange byimikorere yibibaho byumuzunguruko, biganisha ku ngingo ikomeye mubushobozi bwo kurwanya kwivanga bikavamo imikorere mibi;
3. Ubushyuhe buke bwubushyuhe bwibigize Kuva kumubare munini wibikorwa byo kubungabunga, ituze ryumuriro wa capacitori ya mbere ya electrolytike irakennye, ikurikirwa nizindi capacator, triode, diode, IC, résistoriste, nibindi;
4. Hariho ubuhehere, kwirundanya ivumbi, nibindi kurubaho.Ubushuhe hamwe n ivumbi bizotwara amashanyarazi hamwe ningaruka zo guhangana, kandi agaciro kokurwanya kazahinduka mugihe cyo kwagura ubushyuhe.Agaciro ko kurwanya karimo ingaruka zibangikanye nibindi bice.Niba iyi ngaruka ikomeye, ibipimo byumuzingi bizahinduka, bitera amakosa;
5. Porogaramu nayo ni kimwe mu bintu ugomba gusuzuma.Ibipimo byinshi mumuzunguruko byahinduwe ukoresheje software, kandi marike yibipimo bimwe byashyizwe hasi cyane, biri murwego rukomeye.Iyo imashini ikora imiterere yujuje impamvu ya software kugirango umenye amakosa, impuruza izagaragara.
