Flip nti COB yog lub teeb pom kev tshwj xeeb tsim rau LED daim ntawv thov teeb pom kev lag luam, nrog kev kub siab ua haujlwm, kub tsis kam, siab luminous efficiency, siab xim rendering, qis
Lub teeb lwj, tsis ntshai ntawm nias, tsis muaj hlau hlau, tsis muaj teeb pom kev zoo, thiab lwm yam zoo. Lub flip-chip COB lub teeb qhov chaw txais COB ntim daim ntawv tsis muaj cov qauv kub hlau, uas txuag nqi
qhov no. Lub substrate ncoo thiab nti electrode yog ncaj qha welded nrog nano-theem solder paste, uas yog ruaj khov pasted, muaj zog thermal conductivity, thiab muaj ntau dua lub teeb reflection efficiency thiab qis dua qhov poob kuj yuav ua rau lub nti tiv taus ntau dua tsav tam sim no, uas yog yooj yim rau cov neeg siv khoom siv qhov hloov tau yooj yim ntawm cov khoom siv hluav taws xob xaiv. Flip COB teeb qhov chaw raws li goofy
Lub teeb ci tseem ceeb tshaj plaws los ntawm GUANGMAITechnology Co., Ltd., cov khoom tsis tu ncua tau khaws cia rau lub sijhawm ntev, thiab tuaj yeem hloov kho raws li cov neeg siv khoom.
Tsawg-carbon lub neej, qhov chaw tshiab, kev ruaj ntseg zoo, thov so assured mus yuav.

Flip chip LED teeb qhov chaw
Dab tsi yog qhov flip nti ntawm LED teeb qhov chaw? Nyob rau hauv xyoo tas los no, nyob rau hauv daim teb ntawm chips, flip chip technology yog tshwm sim, tshwj xeeb tshaj yog nyob rau hauv lub high-power, sab nraum zoov daim ntawv thov kev lag luam. Tab sis vim yog txoj kev loj hlob lig, ntau tus neeg tsis paub tias LED lub teeb ci yog dab tsi?
Yuav kom nkag siab txog LED lub teeb qhov chaw flip nti, peb yuav tsum xub to taub dab tsi yog LED teeb qhov chaw tsim nti!
LED lub teeb qhov chaw yog thawj nti qauv uas yuav tsum tau mounted rau ntawm lub nti, thiab nws kuj yog lub nti qauv uas feem ntau siv nyob rau hauv tsawg-power chips. Cov qauv electrode nyob rau sab saum toj, thiab cov ntaub ntawv los ntawm sab saum toj mus rau hauv qab yog: P-GaN, lub teeb-emitting txheej, N-GaN, substrate. Yog li, txheeb ze rau flipping, nws yog formal
Flip-chip thev naus laus zis tsis yog lub tshuab tshiab, qhov tseeb nws tau muaj nyob rau lub sijhawm ntev dhau los. Flip-chip thev naus laus zis tsis yog tsuas yog siv hauv LED kev lag luam, tab sis kuj nyob rau hauv lwm yam kev lag luam semiconductor. Tam sim no, LED nti ntim tshuab tau tsim ntau hom, thiab cov thev naus laus zis sib txawv sib txawv rau cov ntawv thov sib txawv thiab muaj lawv tus kheej tshwj xeeb.
Tam sim no, feem ntau yog peb lub tsev kawm ntawv ntawm LED lub teeb ci chip qauv, feem ntau yog cov qauv tsim, muaj cov qauv ntsug thiab cov qauv tig. Vim hais tias cov p thiab n electrodes nyob rau tib sab ntawm LED teeb qhov chaw, lub pem hauv ntej-mounted qauv yog nquag mus rau tam sim no neeg coob coob, thiab lub thermal kuj yog siab. Cov qauv ntsug tuaj yeem daws ob qhov teeb meem no tau zoo, thiab tuaj yeem ua tiav qhov ceev tam sim no thiab qhov sib xws.
Ntxiv nrog rau cov nqi ntawm cov khoom siv yav tom ntej, tus nqi ntawm cov teeb thiab teeb yuav raug txo. Nws yog ib qho tseem ceeb tshwj xeeb los ua kom lub zog thiab txo cov naj npawb ntawm cov teeb ci LED. Cov qauv ntsug tuaj yeem ua tau raws li qhov xav tau no. Qhov no kuj ua rau cov qauv ntsug uas feem ntau yog siv rau hauv high-power LED lub teeb daim ntawv thov, thaum lub sij hawm mounting technology feem ntau yog siv nyob rau hauv tsawg- thiab nruab nrab-lub zog LED qhov chaw.
Lub tshuab flip-chip kuj tseem tuaj yeem muab faib ua ob pawg. Ib qho yog flip-chip raws li cov sapphire nti, sapphire substrate yog khaws cia, uas yog qhov zoo rau cov cua sov dissipation, tab sis qhov ceev tam sim no tsis loj hlob; lwm yam yog lub flip-chip qauv thiab lub hauv ob sab phlu yog stripped. Cov khoom hauv qab yog nce ntxiv rau qhov ceev tam sim no.
