LED zaub yog cov khoom siv hluav taws xob. Tsuav lawv yog cov khoom siv hluav taws xob, lawv yuav ua tsis tiav thaum siv. Yog li dab tsi yog cov lus qhia rau kev kho LED zaub?
Cov phooj ywg uas tau ntsib nrog cov lus qhia LED paub tias cov lus qhia LED tau sib txuas ua ke los ntawm cov khoom ntawm LED modules. Raws li tau hais ua ntej lawm, LED cov ntxaij vab tshaus yog cov khoom siv hluav taws xob, yog li nws cov qauv yooj yim yog cov duab saum npoo (teeb teeb), PCB (lub rooj tsavxwm), thiab tswj qhov chaw (IC tivthaiv nto).
Hais txog cov lus qhia rau kev kho LED zaub, cia peb tham txog kev ua txhaum ua ntej. Cov kev ua txhaum feem ntau suav nrog: ib nrab "tuag teeb", "kab ntsig", ib nrab ntawm cov xim uas ploj lawm, ib nrab ntawm cov ntxaij vab tshaus dub, cov ntxaij vab tshaus dub loj, cov lej tsis sib xws, thiab lwm yam.
Yog li yuav ua li cas kho cov glitches no? Ua ntej, npaj cov cuab yeej kho. Tsib daim ntawm cov khoom muaj nqis rau cov neeg ua haujlwm saib xyuas ntawm LED zaub: tweezers, phom cua kub, cov hlau nplaum, multimeter, daim npav xeem. Lwm cov ntaub ntawv pabcuam suav nrog: solder paste (tin hlau), flux txhawb, tooj liab hlau, kua nplaum, thiab lwm yam.
1. Ib feem ntawm "tuag teeb" teeb meem
Hauv zos "tuag lub teeb" hais txog qhov tseeb tias ib lossis ob peb lub teeb ntawm lub teeb saum npoo ntawm LED zaub tsis ci. Hom kev tsis kaj siab no tau muab faib ua qhov tsis muaj qhov ci puv sijhawm thiab ib nrab xim tsis ua haujlwm. Feem ntau, qhov teeb meem no yog tias lub teeb nws tus kheej muaj teeb meem. Txawm nws ntub los yog RGB nti puas lawm. Peb txoj kev kho yog yooj yim heev, tsuas yog hloov nws nrog lub Hoobkas-nruab nrab LED teeb hlaws. Cov cuab yeej siv yog tweezers thiab phom cua kub. Tom qab hloov cov khoom seem ntawm LED teeb hlaws, siv Test daim npav dua, yog tias tsis muaj teeb meem, nws tau kho.
2. Qhov teeb meem "kab ntsig".
"Caterpillar" tsuas yog ib qho piv txwv, uas yog hais txog qhov tshwm sim uas ntev tsaus nti thiab ci ntsa iab tshwm nyob rau ntawm ib feem ntawm lub teeb saum npoo thaum lub teeb pom kev zoo ntawm LED thiab tsis muaj qhov nkag, thiab xim feem ntau yog liab. Lub hauv paus ua rau ntawm qhov tshwm sim no yog qhov xau ntawm cov nti sab hauv ntawm lub teeb, lossis luv luv ntawm IC nto raj kab tom qab lub teeb, qhov qub yog feem ntau. Feem ntau, thaum qhov no tshwm sim, peb tsuas yog yuav tsum tau siv rab phom cua kub los tshuab cua kub raws li qhov "kab ntsig". Thaum nws tshuab mus rau qhov teeb meem teeb meem, feem ntau nws yog OK, vim hais tias lub tshav kub ua rau lub sab hauv to taub nti txuas. Nws tau qhib lawm, tab sis tseem muaj kev phom sij zais. Peb tsuas yog yuav tsum tau nrhiav lub teeb ci ntsa iab LED hlaws, thiab hloov lub teeb ci ntsa iab no raws li txoj kev hais saum toj no. Yog hais tias nws yog luv luv Circuit Court ntawm kab raj nyob rau sab nraum qab ntawm IC, koj yuav tsum tau siv ib tug multimeter los ntsuas qhov cuam tshuam IC pin Circuit Court thiab hloov nws nrog ib tug tshiab IC.
3. Ib nrab xim blocks ploj lawm
Cov phooj ywg uas paub txog LED zaub yuav tsum tau pom cov teeb meem no, uas yog, ib qho square me me ntawm cov xim sib txawv tshwm sim thaum LED zaub ua si ib txwm, thiab nws yog square. Qhov teeb meem no feem ntau yog xim IC tom qab cov xim thaiv raug hlawv. Qhov kev daws teeb meem yog hloov nws nrog IC tshiab.
4. ib nrab lub vijtsam dub thiab thaj tsam loj dub npo
Feem ntau hais lus, lub vijtsam dub txhais tau hais tias thaum lub vijtsam LED ua si ib txwm, ib lossis ntau lub LED modules qhia qhov tshwm sim uas tag nrho cheeb tsam tsis kaj, thiab thaj tsam ntawm ob peb LED modules tsis kaj. Peb hu nws ib nrab dub screen. Peb hu ntau thaj chaw. Nws yog ib tug loj dub screen. Thaum qhov tshwm sim no tshwm sim, peb feem ntau xav txog lub zog ua ntej. Feem ntau, xyuas seb lub ntsuas hluav taws xob LED puas ua haujlwm li qub. Yog tias qhov ntsuas hluav taws xob LED tsis ci, nws feem ntau yog vim tias lub zog hluav taws xob puas lawm. Tsuas yog hloov nws nrog ib qho tshiab nrog lub zog sib xws. Koj yuav tsum tau xyuas seb lub hwj chim qaum ntawm LED module sib raug rau lub vijtsam dub yog xoob. Feem ntau, rov twisting xov kuj tuaj yeem daws qhov teeb meem ntawm lub vijtsam dub.
5. ib nrab garbled
Qhov teeb meem ntawm cov lej garbled hauv zos yog qhov nyuaj dua. Nws yog hais txog qhov tshwm sim ntawm random, tsis xwm yeem, thiab tejzaum nws flickering xim blocks nyob rau hauv ib cheeb tsam thaum lub LED zaub screen ua si. Thaum qhov teeb meem zoo li no tshwm sim, peb feem ntau yog thawj qhov teeb meem ntawm cov teeb liab kab kev sib txuas teeb meem, koj tuaj yeem tshawb xyuas seb cov kab hluav taws xob puas raug hlawv, seb lub network cable puas xoob, thiab lwm yam. Nyob rau hauv kev saib xyuas, peb pom tias aluminium-magnesium hlau cable yog ib qho yooj yim mus hlawv tawm, thaum lub ntshiab tooj liab cable muaj lub neej ntev. Yog tias tsis muaj teeb meem hauv kev txheeb xyuas tag nrho cov teeb liab kev sib txuas, tom qab ntawd hloov qhov teeb meem LED module nrog rau qhov chaw ua si ib txwm nyob ib puag ncig, koj tuaj yeem txiav txim siab seb puas muaj peev xwm ua tau tias LED module sib raug rau qhov chaw ua si tsis zoo, thiab qhov ua rau muaj kev puas tsuaj. qhov kev puas tsuaj feem ntau yog teeb meem IC. , Cov txheej txheem txij nkawm yuav nyuaj dua. Kuv yuav tsis mus rau hauv cov ntsiab lus ntawm no.
