LED zaub tau siv dav, muaj cov duab meej, lub neej ntev, thiab kev siv hluav taws xob tsawg. Yog tias qhov tsim ntawm LED zaub tsis tsim nyog, nws yuav cuam tshuam rau kev siv yav tom ntej. Kab lus no tau sau txog yim yam thiab qhia rau txhua tus neeg uas yuav tsum tau them sai sai rau hauv kev tsim cov duab LED, kom txhua tus neeg tuaj yeem zam cov teeb meem no thiab tsim ib qho kev tshawb fawb thiab zoo tshaj plaws LED zaub.
Sab nraum zoov HD LED zaub
1. Thaum tshav kub kub dissipation tsim
Cov khoom siv LED yuav ua kom sov thaum nws ua haujlwm. Qhov kub ntau dhau yuav cuam tshuam rau qhov attenuation ceev thiab stability ntawm LED. Yog li ntawd, lub tshav kub dissipation tsim ntawm PCB board thiab qhov cua thiab cua kub dissipation tsim ntawm lub txee yuav cuam tshuam rau kev ua tau zoo ntawm LED.
2. Cov teeb sib xyaw
LEDs ntawm tib xim thiab sib txawv brightness theem yuav tsum tau muab sib xyaw, los yog muab tso rau raws li lub teeb insertion daim duab tsim raws li txoj cai discrete, los xyuas kom meej qhov sib xws ntawm brightness ntawm txhua xim ntawm tag nrho cov screen. Yog tias muaj teeb meem hauv cov txheej txheem no, qhov ci ntsa iab hauv cheeb tsam ntawm lub vijtsam loj yuav tsis sib haum, uas yuav cuam tshuam ncaj qha rau cov nyhuv ntawm lub vijtsam loj LED.
3. Tsim tus nqi tam sim no
Lub nominal tam sim no ntawm LED yog 20mA. Feem ntau, nws raug nquahu kom siv qhov tam sim no uas tsis tshaj 80 feem pua ntawm tus nqi nominal. Tshwj xeeb tshaj yog rau cov ntxaij vab tshaus loj nrog lub suab me me, tus nqi tam sim no yuav tsum raug txo vim qhov tsis zoo ntawm cov cua sov dissipation. Raws li kev paub dhau los, vim tias qhov tsis sib xws ntawm qhov attenuation ceev ntawm cov liab, ntsuab, thiab xiav LEDs, tam sim no tus nqi ntawm cov xiav thiab ntsuab LEDs yuav tsum tau txo nyob rau hauv lub hom phiaj kom muaj kev sib npaug ntawm cov dawb tshuav tom qab lub vijtsam loj. yog siv tau ntev.
4. Tsav Circuit Court tsim
Kev teeb tsa ntawm tus tsav tsheb IC ntawm lub rooj tsav xwm tsav tsheb ntawm lub vijtsam loj yuav cuam tshuam qhov ci ntawm LED. Txij li thaum cov zis tam sim no ntawm tus tsav tsheb IC kis tau deb dhau ntawm lub rooj tsav xwm PCB, qhov hluav taws xob poob ntawm txoj kev sib kis yuav loj dhau, cuam tshuam rau qhov kev ua haujlwm ib txwm muaj ntawm LED thiab ua rau nws qhov ci ntsa iab. Peb feem ntau pom tias qhov ci ntsa iab ntawm LEDs nyob ib ncig ntawm lub vijtsam loj ntawm lub vijtsam yog qis dua hauv nruab nrab, uas yog vim li cas. Yog li ntawd, txhawm rau kom ntseeg tau tias qhov sib xws ntawm qhov ci ntawm lub vijtsam loj, nws yog ib qho tsim nyog los tsim tus tsav tsheb Circuit Court faib daim duab.
5. Tswj lub verticality ntawm lub teeb
Nyob rau hauv-kab LEDs, yuav tsum muaj cov txheej txheem txaus los xyuas kom meej tias cov LED yog perpendicular rau lub PCB board thaum dhau lub cub tawg. Ib qho kev sib txawv yuav cuam tshuam qhov ci ntsa iab ntawm LED uas tau teeb tsa, thiab cov xim thaiv nrog qhov ci tsis sib xws yuav tshwm sim.
6. Vuam tswj
Thaum lub LED tsis ci ntawm lub vijtsam loj LED, feem ntau muaj ntau dua 50 feem pua qhov tshwm sim uas nws yog tshwm sim los ntawm ntau hom kev siv hluav taws xob, xws li LED tus pin soldering, IC tus pin soldering, tus pin header soldering, thiab lwm yam. cov teeb meem no yuav tsum nruj me ntsis txhim kho cov txheej txheem thiab ntxiv dag zog rau kev soj ntsuam zoo kom daws tau. Kev ntsuas kev vibration ua ntej tawm hauv lub Hoobkas kuj yog ib txoj kev tshuaj xyuas zoo.
7. Kub thiab lub sij hawm ntawm yoj soldering
Qhov kub thiab lub sij hawm ntawm yoj pem hauv ntej vuam yuav tsum nruj me ntsis tswj. Nws raug pom zoo tias qhov ntsuas kub ua ntej yog 100 degree ± 5 degree, tsis tshaj 120 degree, thiab qhov kub ua ntej yuav tsum nce siab. Lub vuam kub yog 245 degree ± 5 degree, thiab lub sijhawm vuam yog 245 degree ± 5 degree. Nws raug nquahu kom tsis pub ntau tshaj 3 vib nas this, thiab tsis txhob co los yog poob siab lub LED tom qab lub cub tawg, kom txog rau thaum lub cev kub li qub tau rov qab los. Qhov ntsuas kub ntawm lub tshuab yoj soldering yuav tsum tau kuaj xyuas tsis tu ncua. Qhov no yog txiav txim los ntawm cov yam ntxwv ntawm LED. Kev kub dhau los yog qhov kub thiab txias yuav ua rau lub LED puas ncaj qha lossis ua rau muaj teeb meem tsis zoo, tshwj xeeb tshaj yog rau cov me me puag ncig thiab oval LEDs xws li 3 hli.
8. Anti-static
LED loj screen los ua ke factories yuav tsum muaj kev tiv thaiv zoo li qub. Dedicated anti-static av, anti-static pem teb, anti-static soldering hlau, anti-static rooj lev, anti-static nplhaib, anti-static khaub ncaws, av noo tswj, khoom siv hauv av (tshwj xeeb tshaj yog cov ko taw cutter), thiab lwm yam. yuav tsum tau, thiab yuav tsum tau xyuas tsis tu ncua nrog ib tug static meter .
