Nrog rau kev loj hlob sai ntawm cov cuab yeej tso saib, tsis ntev los no, COB ntim cov khoom tau dhau los ua qhov kub tshiab nyiam nyob rau hauv nruab nrab-rau-high-end zaub ua lag luam, thiab tau dhau los ua tus qauv ntawm yav tom ntej. COB yog dab tsi? Cia tus editor muab cov lus qhia ntxaws ntxaws rau koj hnub no:
LED zaub technology
Tam sim no, feem ntau yog ob daim ntawv ntim tshuab rau cov xim puv xim LED me-pitch qhia, ib qho yog SMD nto mount tivthaiv tshuab, thiab lwm yam yog COB kev ntim tshuab. Surface mount Cheebtsam tau qhia txog nees nkaum xyoo dhau los. Los ntawm cov khoom siv hluav taws xob mus rau cov khoom siv hluav taws xob thiab cov khoom siv sib xyaw ua ke, lawv thiaj li dhau los ua cov khoom siv saum npoo av (SMD) thiab tuaj yeem sib sau ua ke los ntawm cov khoom siv thiab chaw. COB yog lub tshuab ntim khoom lag luam tshiab uas tsuas yog siv rau puv xim LED cov ntxaij vab tshaus ntawm qhov loj hauv xyoo tas los.
SMD ntim tshuab
SMD: Nws yog lub ntsiab lus ntawm Surface Mounted Devices, uas txhais tau tias: nto mount ntaus ntawv, uas yog ib qho ntawm SMT (Nto Mount Technology) Cheebtsam. Tam sim no, sab hauv tsev puv xim LED cov ntxaij vab tshaus feem ntau tau txais qhov chaw-mount peb-hauv-ib SMD, uas yog hais txog kev ntim tshuab ntawm encapsulating SMT teeb nrog peb xim sib txawv ntawm RGB LED chips hauv tib lub gel ntawm qee lub sijhawm los tsim ib qho zaub module.
Cov txheej txheem tseem ceeb yog encapsulate LED teeb-emitting nti nyob rau hauv lub bracket los tsim cov hlaws dai (SMD nto mount qhov chaw), thiab lub teeb hlaws dai ces txuas mus rau PCB board los ntawm soldering. Tom qab ntawd muab cov mounting qhov chaw thiab PCB lub rooj tsavxwm rau hauv qhov cub kub kub rau sintering thiab solidification (reflow soldering), thiab tom qab ntawd siv lub tshuab vuam siab los xaim LED, thiab thaum kawg encapsulate lub bracket nrog epoxy resin los ua ib qho screen module. Tom qab ntawd, cov modules yog spliced rau hauv units.

Cov khoom tseem ceeb ntawm SMD txheej txheem:
Bracket: Kev siv hluav taws xob, kev txhawb nqa thiab cua sov dissipation. Feem ntau ntawm cov khoom siv bracket yog tsim los ntawm electroplating, muaj tsib txheej ntawm cov khoom, tooj liab, npib tsib xee, tooj liab, thiab nyiaj ntawm sab hauv mus rau sab nraud.
LED nti: Cov nti yog cov khoom tseem ceeb ntawm LED Teeb, thiab nws yog cov khoom siv hluav taws xob semiconductor.
Cov xaim hluav taws xob: txuas lub nti PAD (pad) thiab lub bracket, thiab ua kom nws muaj zog.
Epoxy resin: tiv thaiv cov qauv sab hauv ntawm lub teeb hlaws, thiab tuaj yeem hloov me ntsis lub teeb-emitting xim, ci ntsa iab thiab lub kaum sab xis ntawm lub teeb hlaws;
COB ntim tshuab
COB: yog lub ntsiab lus ntawm Chip On Board. Txhais: Chip-on-board ntim tshuab; uas yog, ib tug semiconductor ntim txheej txheem nyob rau hauv uas lub nti yog adhered rau lub interconnect substrate nrog conductive los yog non-conductive kua nplaum, thiab ces xaim-bonded mus cuag nws cov hluav taws xob kev twb kev txuas. Txhawm rau muab nws yooj yim, lub teeb-emitting nti yog ncaj qha mounted ntawm PCB pawg thawj coj saib yam tsis tas yuav tsum muaj cov brackets thiab solder taw. Piv nrog rau cov tsoos SMD mus kom ze, COB ntim tshem tawm ob txoj kev loj ntawm kev ua LED chips rau hauv lub teeb hlaws thiab reflow soldering. Yeej, cov nti tau sib dhos ncaj qha rau PCB yam tsis muaj qhov txwv ntawm qhov loj ntawm cov khoom ntim, thiab qhov me me ntawm qhov kev teeb tsa tuaj yeem pom tau. Micro LED tam sim no txais COB thev naus laus zis.

Piv nrog rau lwm cov txheej txheem ntim tshuab, cov txheej txheem ntawm COB thev naus laus zis yog qhov yooj yim thiab yooj yim, raws li qhia hauv daim duab hauv qab no:
COB ntim tshuab
LED npo nta ntawm COB ntim tshuab:
1. Super "stability": yuav luag tsis muaj qhov txhaum thiab tsis muaj qhov chaw tuag.
2. Tsis yog "dazzling": siv qhov chaw teeb pom kev zoo es tsis txhob "dazzling" point light sources thiab lwm yam kev tiv thaiv ib puag ncig. Lub ci ci yog mos thiab tiv thaiv tib neeg lub qhov muag.
3. Tsis "squeaky": tsis ntshai ntawm pob, tuaj yeem so nrog dej, tiv thaiv qib IP66.
4. Tsis muaj "seam": koj tuaj yeem "customize" cov lus qhia ntawm cov nplai sib txawv.
5. Siv "ntev lub neej": 24 teev thiab 365 hnub ntawm kev siv tsis tu ncua rau ntau tshaj 8 xyoo (kev tshawb xav 10 xyoo).
6. "Nws yog lub neej yav tom ntej": Nws yuav hloov DLP, LCD, plasma, projection, movie screen, SMD LED zaub thiab lwm yam khoom siv.
Kev faib tawm ntawm qhov sib txawv ntawm lub cev sib xws rau cov txheej txheem ntim sib txawv ntawm LED zaub
Kev faib tawm ntawm qhov sib txawv ntawm lub cev sib xws rau cov txheej txheem ntim sib txawv ntawm LED zaub
Nyob rau hauv lub neej yav tom ntej, lub mainstream zaub technology micro-pitch Micro-LED, lub micro-pitch yuav ua infinitely me me nyob rau hauv txoj kev xav, thiab nws yog ib tug zoo-pitch zaub technology raws li COB ntim.
