Ua ntej, txoj kev nrhiav kom tau ntawm LED zaub kho dua
1. Kev txiav txim siab luv-Circuit Court, lub teeb pom kev zoo hloov kho qhov multimeter rau qhov luv-Circuit Court nrhiav thaiv (feem ntau nrog lub tswb ua haujlwm, xws li kev tshaj tawm pej xeem tshaj tawm lub suab ntawm squeak, kom paub seb puas muaj luv luv tshwm sim, thiab tam sim ntawd tom qab qhov luv luv Circuit Court pom, qhov teeb meem luv luv ntawm Circuit Court kuj yog qhov teeb meem LED cov teeb pom kev zoo tshaj plaws. Ib txhia tuaj yeem nrhiav tau los ntawm kev tshawb xyuas IC tus pin thiab lub hauv paus. Lub luv luv Circuit Court yuav tsum tau ua thaum muaj lub zog tsis ua hauj lwm kom tsis txhob muaj kev puas tsuaj rau ntau tus multimeter.Qhov qauv no yog siv feem ntau, qhov yooj yim thiab siv tau.Qhov 90% ntawm cov teeb meem tuaj yeem pom los ntawm hom no.
2. Txoj kev tiv thaiv cov txheej txheem, kho qhov multimeter rau cov ntawv thev naus laus zis, kuaj pom tus nqi tsis kam ntawm qee qhov taw tes ntawm lub rooj tsav xwm hauv lub cev, thiab tom qab ntawd xyuas seb qhov ntsuas ntawm qhov ntsuas ntawm lwm lub Circuit Court sib txawv puas txawv ntawm tus nqi qub. Yog tias nws txawv, cov nplai ntawm cov teeb meem tau txiav txim siab.
3. Kev ntsuas qhov ntsuas qhov ntsuas hluav taws xob, kho lub multimeter rau cov ntawv pov thawj voltage, ntsuas qhov voltage mus rau hauv av ntawm qee qhov taw tes ntawm Circuit Court xav tias muaj teeb meem, sib piv seb nws zoo li tus nqi qub, thiab yooj yim txiav txim siab qhov nplai ntawm teeb meem.
4. Qhov ntsuas hluav taws xob voltage nrhiav kom tau txoj kev, qhov ntev yog kho kom haum rau cov diode voltage poob qis kom paub cov ntaub ntawv, vim tias tag nrho IC yog tsim ntawm ntau chav ntsuas theem, tsuas yog miniaturized, yog li thaum muaj lub sijhawm tam sim no ntawm ib qho ntawm nws cov pins, Muaj yuav yog qhov voltage hla thoob tus pin. Feem ntau, qhov poob hluav taws xob poob rau ntawm tus pin ntawm tib lub IC sib npaug. Raws li qhov voltage poob tus nqi ntawm tus pin, nws yog ib qho tsim nyog yuav tsum tau khiav lag luam hauv qab teeb meem uas lub Circuit Court raug tsav tawm.
Qhov thib ob, cov theem pib ntawm LED zaub kho
1. Kev txiav txim siab hom HUB board siv los ntawm pawg los yog pawg tswj hwm, yog li ntawd qhov kev cuam tshuam interface ntawm cable yog tib yam.
2. Raws li ntau hom module lossis pawg tswj hwm, cov kev pabcuam coj los raug xa mus rau daim npav tau txais, thiab cov ntawv pob tshab xyuas kom meej tias cov qauv thiab pawg ntsuas tau pom nyob rau hauv cov phiaj xwm kom raug, uas yog ib qho xwm txheej los nrhiav qhov ua rau. ntawm qhov teeb meem. Cov hom ntawm cov qauv lossis cov xov tooj ntawm tes yog feem ntau luam tawm ntawm PCB.
3. Saib xyuas qhov teeb meem lossis qhov tshwm sim ntawm pawg tswj hwm, thiab txiav txim siab qhov txhaum thawj zaug. Piv txwv, cov xenon lub teeb nrawm, cov ntsiab lus hlua, cov fab me me, thiab lwm yam.
4. Siv multimeter los nrhiav qhov teeb meem, feem ntau yog siv cov kev qhia luv luv ntawm xov xwm sab saum toj kom pom ntawm qhov nti thiab lub teeb ko taw.
5. Tshawb xyuas ntxiv
