Raws li cov ntaub ntawv loj qhia tau hais tias LED tuag teeb yuav ntau tshaj 100 lub hauv paus, tsuas pub rau lub sijhawm, hnub no peb tsuas yog LED teeb qhov chaw, piv txwv li, los ntawm LED teeb qhov chaw ntawm tsib yam raw khoom (chips, stents, phosphor, kua nplaum thiab kub kab) pib, ua kom paub txog qee cov laj thawj uas ua rau cov teeb cig tuag taus.
Hnub no, peb LED tuag ua piv txwv, los sojntsuam cov laj thawj ntawm cov laj thawj:
Los tsis ua haujlwm ntawm cov ntaub ntawv loj qhia tau tias LED tuag lub teeb yuav muaj ntau dua li 100 lub sijhawm, hnub no peb tsuas yog LED teeb qhov chaw, piv txwv li, los ntawm tsib qhov chaw loj ntawm LED qhov chaw (chip, bracket, phosphor, solid crystal , Thiab kub kab) pib, ua kom paub txog qee cov laj thawj uas yuav ua rau cov teeb cig tuag.
C siab
1 .C siab ntawm lub peev xwm tiv thaiv tsis zoo yog tsis zoo
LED teeb hlaws dai ntawm cov teeb meem tiv thaiv kev tiv thaiv uas yog nyob ntawm lub teeb ci-emitting chip nws tus kheej, thiab cov ntaub ntawv ntim yuav tsum tau pob khoom ua haujlwm tsis muaj dab tsi los ua, los yog kev cuam tshuam ntawm yam tseem ceeb me me, heev tsis yooj yim; LED teeb muaj ntau dua susceptible electrostatic puas tsuaj, uas yog qhov kev ncua deb ntawm ob pins Kev txheeb ze, LED chip tuag spacing ntawm ob lub electrodes yog me me, feem ntau li ntawm ib puas microns, thiab tus pin tus pin txog li 2 millimeters, thaum lub electrostatic them nyiaj kom hloov, qhov ntau dua qhov yov, qhov feem ntau yuav tsim ib qho kev sib txawv loj, Qhov ntawd yog qhov siab tshaj plaws. Yog li, qhov teebmeem ntawm cov teeb cig tuaj yeem yog qhov teebmeem hluavtaws ntau dua.
2 .C plawv epitaxial tsis xws luag
LED epitaxial wafers nyob rau hauv txoj kev kub siab, lub substrate, MOCVD cov tshuaj tiv thaiv chamber residual sediment, peripheral roj thiab Mo lub hauv paus yuav ua rau cov impurities, cov impurities yuav nkag mus rau epitaxial txheej, tiv thaiv gallium nitride Crystal nucleation, tsim ntawm ntau yam Muaj ntau hom epitaxial tsis meej, thiab thaum kawg nyob rau hauv txheej epitaxial txheej ntawm tsim qhov me me, uas yuav cuam tshuam rau epitaxial wafer zaj duab xis cov khoom zoo thiab kev ua haujlwm.
3 . C Hip chemical residues
Electrode processing yog lub txheej txheem tseem ceeb rau kev ua kom muaj lub koob thaij duab, xws li tu, txhuam, daj, tshuaj lom neeg, fusion, sib tsoo, yuav tuaj rau hauv kev sib txuas nrog tshuaj tshuaj tu ntau ntau, yog lub nti tsis huv txaus, . Cov tshuaj lom no yuav ua rau lub hwjchim ci ntsa iab, thiab cov hluav taws xob electrochemical nrog cov electrode, uas ua rau cov teeb tuag, lub teeb tsis ua haujlwm, tsaus, dub thiab lwm yam. Yog li ntawd, qhov cim ntawm chip tshuaj residues nyob rau ntawm lub hnab ntim cov nroj tsuag yog qhov tseem ceeb.
4 .Tus nws nti raug puas ntsoog
LED nti kev puas tsuaj yuav ua rau ncaj qha mus rau kev tsis ua haujlwm LED, yog li ua kom ntseeg tau tias cov teeb meem ntawm LED yog qhov tseem ceeb. Thaum lub sij hawm evaporation txheej txheem, nws yog tej zaum yuav tsum tau txhim kho lub nti nrog ib tug caij nplooj ntoos hlav clip, yog li tsim ib tug clip. Huangguang lag luam yog tias txoj kev loj hlob tsis tiav thiab lub npog ncauj muaj ib lub qhov yuav ua rau thaj chaw teeb muaj ntau qhov chaw seem hlau. Ntsuas hauv cov txheej txheem dhau los, cov txheej txheem xws li kev tu vaj tse, evaporation, daj, tshuaj lom neeg, fusion, sib tsoo thiab lwm yam haujlwm yuav tsum tau siv cov caws pliav thiab cov pob tawb, cov tsheb, thiab lwm yam.
Chip electrode nyob rau hauv txoj kab sib dhos: chip electrode nws tus kheej tsis yog khoom, ua rau hauv lub lauj kaub xuab zeb tom qab lub electrode tawm los yog kev puas tsuaj; nti electrode nws tus kheej pluag solderability, nws yuav ua rau cov khoom siv laug solder; chip cia yuav ua rau tsis pom zoo electrode qhov chaw oxidation, qhov chaw contamination Thiab zoo li ntawd, me ntsis ntawm qhov sib tsoo ntawm qhov sib dhos yuav cuam tshuam cov diffusion ntawm hlau atoms ntawm ob, ua rau tsis ua haujlwm lossis Weld.
5 . tus qauv tshiab ntawm lub nti thiab cov khoom siv yog tsis sib xws
Tus qauv tshiab ntawm cov roj ntim khoom electrode nrog ib txheej ntawm txhuas, lub luag hauj lwm ntawm lub electrode nyob rau hauv lub tsim ntawm ib txheej ntawm tsom iav kom zoo dua ntawm cov nti, ces raws li ib tug twg, txo cov nqi kub siv nyob rau hauv lub deposition electrode kom txo nqi. Tiam sis aluminium yog ib qho tseem ceeb heev hlau, thaum lub lag luam cog lax tswj, kev siv chlorine dhau qhov txheem kua, kub electrode hauv txhuas kev txheej txheem yuav hnov mob nrog chlorine hauv kua nplaum, ua rau corrosion.
