COB Ntim txhais li cas? Dab tsi yog qhov txawv ntawm kev ntim khoom

Dab tsi yog COB encapsulated Cache on Board ) Bangbang yog teem rau ntawm lub rooj tsavxwm. Raws li cov neeg muab khoom IC txo qis QFP (ib txoj hauv kev encapsulation ntawm SMT qhov chaw) ntim hauv LCD tswj thiab tsim cov chips cuam tshuam. Yog li ntawd, cov txheej txheem SMT ib txwm nyob rau hauv cov khoom yav tom ntej yog maj mam hloov. Qhov txawv ntawm COB ntim tshuab thiab cov ntim tshuaj? COB ntim yog lub pob uas khi lub LED nti ncaj qha rau ntawm lub rooj tsavxwm PCB. Dab tsi yog qhov txawv ntawm txoj kev ntim khoom no thiab cov tsoos SMD LED thiab lwm yam kev ntim khoom, thiab qhov twg zoo dua? Kev sib piv ntawm ob txoj kev ntim khoom no? Muaj ob hom kev siv tshuab liab qab: ib qho yog COB thev naus laus zis, thiab lwm yam yog FLIP Chip technology (FLIP Chip). LED COB ntim tshuab Lub thiaj li hu ua COB yog ua raws cov liab qab nti nrog conductive los yog tsis-conductive adhesion ntawm interconnected substrate, thiab tom qab ntawd ua tus yuam sij ua kom tiav nws cov hluav taws xob kev twb kev txuas. Yog tias cov nti liab qab raug ncaj qha rau saum huab cua, nws muaj kev cuam tshuam rau kev ua qias tuaj lossis kev puas tsuaj, cuam tshuam lossis rhuav tshem cov haujlwm ntawm cov nti, yog li cov nti thiab cov hlau lead tseem ceeb raug kaw nrog cov kua nplaum. Tib neeg kuj hu daim ntawv ntim no ua lub hnab mos. Cov liab qab nti encapsulated nrog COB thev naus laus zis yog lub nti lub cev thiab I / O terminals saum cov siv lead ua. Thaum lub sij hawm vuam, cov liab qab nti yog nplaum rau PCB nrog conductive / thermal kua nplaum. Tom qab solidification ) Nyob rau hauv qhov kev txiav txim ntawm ultrasound thiab thermal siab, txuas mus rau lub nti I / O lub davhlau ya nyob twg vuam cheeb tsam thiab cov ntaub qhwv ntawm PCB, feem. Tom qab qhov kev xeem dhau lawm, cov kua nplaum resin raug kaw. Piv nrog rau kev ntim khoom siv tshuab, COB tshuab muaj qhov zoo hauv qab no: tus nqi qis; chaw txuag; craftsmanship paub tab. LED COB ntim tshuab kuj tseem tsis txaus, uas yog, lub tshuab vuam cais thiab lub tshuab ntim khoom xav tau. Qee lub sij hawm qhov ceev tsis tuaj yeem ua raws li PCB thaj ua kom nruj rau qhov chaw; nws tsis tuaj yeem khaws cia. COB, lub tshuab ntim khoom siv niaj hnub no yuav ua lub luag haujlwm tseem ceeb hauv kev ntim cov khoom lag luam. Tej teeb meem ntawm LED COB ntim tshuab Q: LED teeb qhov chaw COB ntim txheej txheem Mid -xim kub offset teeb meem. Thaum COB ntim tau siv rau hauv COB ntim, nws siv cov txheej txheem ntim khoom muaj zog. Tom qab ci, nws pom tias cov xim kub ib txwm loj dhau. , 5000K hauv qhov taw qhia ua ntej, tab sis cov kua nplaum nplaum yog 10000K tom qab cov hniav nyiaj hniav kub yog grilled. Puas yog qhov teeb meem ntawm cov txheej txheem ci ntawm silicone lossis cov kua nplaum hmoov tsis haum. Thov sawv daws! A: Qhov kub ntawm qhov ci yog siab dhau lawm, thiab qhov kev ncua deb ntawm electrode yuav ze dhau. Shorten lub sij hawm ntawm cov tshuaj tsuag mus rau lub sij hawm ci. Cov xim kub sib txawv yuav tsum yog los ntawm cov hmoov fluorescent. Ceev ceev kom tsis txhob fluorescence hmoov! Tshawb xyuas cov cua kub nkhaus ntawm lub qhov cub Q: Dab tsi yog qhov txawv ntawm LAMP LED ntim tshuab thiab COB ntim hauv ntim tshuab ntawm LED? Ob leeg yog direct-inserted es tsis txhob thaj ntim. Qhov txawv yog dab tsi? Dab tsi yog yam? Puas yog ib qho haum rau lub zog siab, ib qho rau lub zog me? A: COB tshuab feem ntau siv tau rau tib lub substrate nrog rau lwm yam khoom siv hluav taws xob. Yog tias LED COB tau tsim rau hauv pob khoom ncaj qha, nws yuav tsum yog ib qho module nrog qee qhov tshwj xeeb ua haujlwm xws li flash muaj nuj nqi lossis cov cim digital, xim tswj module, thiab lwm yam. Ob lub zog loj thiab me tuaj yeem yog COB lossis LAMP. Tsis muaj qhov sib txawv ntawm qhov no. Q: Kuv puas tuaj yeem nug COB kev ntim khoom raws li lub dav hlau lub teeb, nws puas yuav hloov cov khoom tam sim no? A: Tsis muaj kev hloov pauv, ob qho tib si nyob rau hauv kev txhim kho yav tom ntej, thiab ob qho tib si yuav nyob ua ke rau lub sijhawm ntev.
