Cov txheej txheem ntim ntawm UV LED lub teeb qhov chaw txawv ntawm lwm cov khoom siv LED, feem ntau yog vim lawv pab cov khoom sib txawv thiab cov kev xav tau. Feem ntau cov teeb pom kev zoo lossis cov khoom lag luam LED tau tsim los ua haujlwm rau tib neeg lub qhov muag, yog li thaum xav txog kev siv lub teeb, koj kuj yuav tsum xav txog tib neeg lub qhov muag muaj peev xwm tiv taus lub teeb muaj zog. Txawm li cas los xij,UV LED curing teebtsis ua hauj lwm rau tib neeg lub qhov muag, yog li lawv tsom rau siab dua lub teeb siv thiab lub zog ceev.
SMT Ntim Txheej Txheem
Tam sim no, feem ntau UV LED teeb hlaws dai ntawm lub khw tau ntim nrog cov txheej txheem SMT. Cov txheej txheem SMT suav nrog kev teeb tsa LED nti rau hauv cov cab kuj, feem ntau hu ua LED bracket. LED cov nqa khoom feem ntau muaj cov thermal thiab hluav taws xob ua haujlwm thiab muab kev tiv thaiv rau cov chips LED. Qee tus kuj yuav tsum tau txhawb nqa LED lo ntsiab muag. Kev lag luam tau faib ntau cov qauv ntawm hom teeb hlaws no raws li qhov sib txawv specifications thiab qauv ntawm cov chips thiab brackets. Qhov kom zoo dua ntawm txoj kev ntim no yog tias cov chaw ntim khoom tuaj yeem tsim cov nplai loj, uas txo cov nqi ntau lawm. Yog li ntawd, ntau tshaj 95% ntawm UV teeb nyob rau hauv kev lag luam LED tam sim no siv cov txheej txheem ntim khoom no. Cov neeg tsim khoom tsis xav tau cov kev cai ntau dhau thiab tuaj yeem tsim ntau yam teeb pom kev zoo thiab cov khoom siv.
COB Ntim Txheej Txheem
Piv rau SMT, lwm txoj kev ntim khoom yog COB ntim. Hauv COB ntim, LED nti yog ntim ncaj qha mus rau lub substrate. Qhov tseeb, txoj kev ntim khoom no yog cov txheej txheem ntim khoom thaum ntxov tshaj plaws. Thaum LED chips tau tsim thawj zaug, engineers tau siv txoj kev ntim khoom no.
Raws li kev lag luam kev nkag siab, UV LED qhov chaw tau nrhiav lub zog siab ceev thiab lub zog kho qhov muag siab, uas yog tshwj xeeb tshaj yog haum rau cov txheej txheem ntim khoom COB. Raws li txoj cai, COB ntim txheej txheem tuaj yeem ua kom lub suab tsis pub ntim rau ib cheeb tsam ntawm lub substrate, yog li ua kom muaj zog ntau dua rau tib cov chips thiab lub teeb emitting cheeb tsam.
Tsis tas li ntawd, COB pob kuj tseem muaj qhov zoo ntawm cov cua sov dissipation, LED chips feem ntau tsuas yog siv ib txoj kev ntawm kev hloov hluav taws xob rau kev hloov hluav taws xob, thiab cov khoom siv hluav taws xob tsawg dua siv nyob rau hauv cov txheej txheem cua sov, qhov ua tau zoo ntawm cov khoom siv hluav taws xob ntau dua.COB pob. txheej txheem, vim hais tias cov nti yog ntim ncaj qha rau ntawm lub substrate, piv nrog rau SMT ntim txoj kev, lub nti mus rau lub tshav kub dab dej ntawm qhov txo ntawm ob hom ntawm tshav kub conduction nruab nrab, uas zoo heev txhim kho kev ua tau zoo thiab stability ntawm lub cov khoom siv hluav taws xob lig. kev ua tau zoo thiab ruaj khov ntawm cov khoom siv teeb pom kev zoo. Yog li ntawd, nyob rau hauv kev lag luam teb ntawm high-power UV LED systems, kev siv COB ntim lub teeb qhov chaw yog qhov zoo tshaj plaws kev xaiv.
Hauv cov ntsiab lus, los ntawm optimizing lub zog tso zis stability ntawmLED UV curing system, sib piv cov wavelengths tsim nyog, tswj irradiation lub sij hawm thiab lub zog, tsim nyog UV hluav taws xob koob tshuaj, tswj curing ib puag ncig tej yam kev mob, thiab coj zoo tswj thiab kev ntsuam xyuas, lub curing zoo ntawm UV inks yuav zoo guaranteed. Qhov no yuav txhim kho kev tsim khoom, txo qis kev tsis lees paub, thiab ua kom cov khoom lag luam ruaj khov.
