Kev tsim cov khoom me me-pitch LED qhia txog cov txheej txheem kev ua haujlwm
1.Ntim tshuab
Me me-pitch LED zaubnrog qhov ntom ntom hauv qab noP2feem ntau siv 0606, 1010, 1515, 2020, 3528 teeb, thiab cov duab ntawm LED pins yog J lossis L pob.Yog hais tias cov pins yog welded sideways, yuav muaj kev cuam tshuam nyob rau hauv qhov chaw vuam, thiab cov xim xim xim yuav tsis zoo.Nws yog ib qho tsim nyog yuav tsum tau ntxiv lub npog ntsej muag txhawm rau txhim kho qhov sib piv.Yog tias qhov ceev ntxiv ntxiv, L lossis J pob tsis tuaj yeem ua tau raws li daim ntawv thov, thiab QFN pob yuav tsum tau siv.Cov yam ntxwv ntawm cov txheej txheem no yog tias tsis muaj welded pins tom qab, thiab qhov chaw vuam yog tsis muaj kev cuam tshuam, uas ua rau cov xim rendering nyhuv zoo heev.Tsis tas li ntawd, tag nrho-dub kev sib xyaw tsim yog molding los ntawm molding, thiab qhov sib piv ntawm qhov screen yog nce 50%, thiab cov duab zoo ntawm daim ntawv thov zaub yog zoo dua li ntawm cov khoom yav dhau los.
2.Mounting technology:
Qhov me ntsis offset ntawm txoj hauj lwm ntawm txhua RGB ntaus ntawv nyob rau hauv lub micro-pitch zaub yuav ua rau cov zaub tsis sib xws ntawm lub vijtsam, uas yog khi rau yuav tsum tau muab cov cuab yeej tso kawm kom muaj qhov tseeb dua.
3. Vuam txheej txheem:
Yog hais tias lub reflow soldering kub nce ceev heev, nws yuav ua rau unbalanced wetting, uas yuav inevitably ua rau lub ntaus ntawv hloov thaum lub sij hawm tus txheej txheem ntawm unbalanced wetting.Cov cua ntau dhau tuaj yeem ua rau cov khoom txav mus los.Sim xaiv lub tshuab reflow soldering nrog ntau tshaj 12 qhov chaw kub, saw ceev, kub nce, circulating cua, thiab lwm yam raws li nruj tswj cov khoom, uas yog, kom ua tau raws li qhov yuav tsum tau ntawm vuam kev ntseeg tau, tab sis kuj yuav txo tau los yog tsis txhob hloov cov khoom. Cheebtsam, thiab sim tswj nws nyob rau hauv lub Scope ntawm kev thov.Feem ntau, 2% ntawm pixel pitch yog siv los tswj tus nqi.
4. Printed Circuit Board txheej txheem:
Nrog rau txoj kev loj hlob ntawm micro-pitch zaub cov ntxaij vab tshaus, 4-txheej thiab 6-txheej boards yog siv, thiab cov ntawv luam tawm Circuit Board yuav txais kev tsim ntawm nplua vias thiab faus qhov.Lub tshuab drilling tshuab tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua, thiab kev tsim kho sai sai laser drilling tshuab yuav ua tau raws li micro qhov ua.
5. Tshuab luam ntawv:
Qhov tsim nyog PCB ncoo tsim yuav tsum tau sib tham nrog cov chaw tsim khoom thiab siv rau hauv kev tsim.Txawm hais tias qhov qhib qhov loj ntawm stencil thiab qhov kev luam ntawv tsis raug yog cuam tshuam ncaj qha rau tus nqi ntawm cov ntawv luam tawm.Feem ntau, 2020RGB cov cuab yeej siv electro-polished laser stencils nrog lub thickness ntawm 0.1-0.12mm, thiab 1.0-0.8 thickness stencils raug pom zoo rau cov khoom siv qis dua 1010RGB.Thickness thiab qhib loj nce nyob rau hauv kev faib ua feem rau tus nqi ntawm tin.Qhov zoo ntawm micro-pitch LED soldering yog ze ze rau solder paste printing.Kev siv cov tshuab luam ntawv ua haujlwm nrog qhov ntsuas tuab thiab SPC tsom xam yuav ua lub luag haujlwm tseem ceeb hauv kev ntseeg tau.
6. Kev sib dhos npo:
Lub thawv sib dhos yuav tsum tau sib sau ua ke rau hauv ib qho screen ua ntej nws tuaj yeem tso saib cov duab thiab cov yeeb yaj kiab zoo.Txawm li cas los xij, qhov ntev ntev ntawm lub thawv nws tus kheej thiab qhov kev ua siab ntev ntawm lub rooj sib txoos tsis tuaj yeem raug ignored rau kev sib dhos nyhuv ntawm micro-pitch zaub.Yog tias lub pixel suab ntawm cov cuab yeej ze tshaj plaws ntawm lub txee thiab lub txee loj dhau los yog me dhau, cov kab tsaus thiab cov kab ci ntsa iab yuav tshwm sim.Qhov teeb meem ntawm cov kab tsaus nti thiab cov kab ci ntsa iab yog qhov teeb meem uas tsis tuaj yeem tsis quav ntsej thiab yuav tsum tau daws sai sai rau cov ntxaij vab tshaus micro-pitch xws liP1.25.Qee lub tuam txhab ua kev hloov kho los ntawm kev nplaum 3m daim kab xev thiab ua tib zoo kho cov txiv ntoo ntawm lub thawv kom ua tiav cov txiaj ntsig zoo tshaj plaws.
7. Lub thawv sib dhos:
Lub txee yog ua los ntawm cov sib txawv modules spliced ua ke.Lub flatness ntawm lub txee thiab qhov sib txawv ntawm cov modules yog ncaj qha cuam tshuam rau tag nrho cov nyhuv ntawm lub txee tom qab sib dhos.Aluminium phaj ua lub thawv thiab cam khwb cia txhuas lub thawv yog cov khoom siv dav tshaj plaws nyob rau tam sim no.Lub flatness tuaj yeem ncav cuag li ntawm 10 xov hlau.Qhov sib txawv ntawm qhov sib txawv ntawm cov modules yog ntsuas los ntawm qhov kev ncua deb ntawm qhov ze pixels ntawm ob modules.kab, ob pixels dhau deb yuav ua rau cov kab tsaus.Ua ntej sib sau ua ke, nws yog ib qho tsim nyog los ntsuas thiab xam qhov sib koom ua ke ntawm lub module, thiab tom qab ntawd xaiv ib daim ntawv hlau ntawm cov txheeb ze thickness raws li lub fixture yuav tsum tau muab tso ua ntej rau kev sib dhos.
