High-quality BGA tin pob yuav tsum muaj cov yam ntxwv ntawm qhov tseeb roundness, brightness, zoo conductivity thiab mechanical linkage kev ua tau zoo, me me pob txoj kab uas hla kam rau ua, oxygen cov ntsiab lus hauv qab, thiab lwm yam.. Cov khoom siv sib txuas lus (cov xov tooj ntawm tes, cov khoom siv sib txuas lus siab), LED, LCD, DVD, computer motherboards, PDA, tsheb LCD TV, tsev ua yeeb yam (AC3 system), satellite positioning system thiab lwm yam khoom siv hluav taws xob. Nws tau tshaj tawm hais tias nyob rau hauv lub tshav pob ntawm 3C electronics, lub ntiaj teb no thov rau tin npas mus txog ntau tshaj kaum billion US dollars ib xyoo, Tuam Tshoj yog lub ntiaj teb no tus loj tshaj plaws siv cov tin pob nyob rau hauv lub teb chaws, thiab qhov kev thov tseem nce xyoo los ntawm lub xyoo. . Qhov no muab kev lag luam dav dav thiab kev loj hlob ze rau cov khoom lag luam tin pob.
LCD motherboard ua lag luam raws li txoj cai
Vaj Huam Sib Luag yog lub ntsiab ntawm cov zaub, muaj feem ntau yog LCD panels, Mini Led thiab OLED peb hom, ntawm cov LCD vaj huam sib luag tseem yog cov kev siv tseem ceeb tam sim no. Cov kua siv lead ua kua (LCD), nws txoj haujlwm tseem ceeb yog hloov qhov voltage ntawm cov kua siv lead ua kua txheej los ntawm tus tsav tsheb IC, kho lub kaum sab xis ntawm deflection ntawm cov kua siv lead ua kua molecules los tswj qhov kev hla thiab thaiv lub teeb, thiab tom qab ntawd siv cov xim lim. kom ua tiav cov zis ntawm cov duab.
LCD vaj huam sib luag kev lag luam tuaj yeem muab faib ua cov khoom siv hluav taws xob sab saud, nruab nrab vaj huam sib luag tsim thiab cov khoom lag luam qis kawg. Ntawm lawv, cov khoom siv hluav taws xob muaj xws li: iav substrate, lim, polarizer, kua siv lead ua kua, tsav nti, thiab lwm yam .; midstream yog LCD LCD ntau lawm kab; Cov khoom siv hauv qab kawg suav nrog: TV, khoos phis tawj, xov tooj ntawm tes thiab lwm yam khoom siv hluav taws xob.
Los ntawm lub ntiaj teb LCD zaub vaj huam sib luag kev lag luam loj, raws li cov ntaub ntawv txheeb cais, lub ntiaj teb cov zaub vaj huam sib luag kev lag luam loj tau mus txog $ 139.2 nphom hauv xyoo 2021, ntawm cov LCD zaub vaj huam sib luag lag luam loj ntawm $ 97.3 billion. Nws cia siab tias nyob rau hauv 2022 lub ntiaj teb no vaj huam sib luag kev lag luam loj yuav poob mus rau 109.5 billion US dollars, nqis 21.40 feem pua rau-xyoo, thiab nyob rau hauv 2023 lub lag luam loj yuav rebound me ntsis rau 115.6 billion US dollars.
Nyob rau hauv cov nqe lus ntawm domestic LCD kev lag luam muaj peev xwm ntau lawm, raws li Tuam Tshoj Electronic Materials Industry Association, Tuam Tshoj lub LCD tsim muaj peev xwm nyob rau hauv 2021 yog 204.89 lab square meters, nce 16.42 feem pua los ntawm 2020, thaum nws xav tias Tuam Tshoj lub LCD muaj peev xwm nyob rau hauv 2025 yuav. ncav cuag 286.33 lab square meters, nrog CAGR ntawm 8.73 feem pua. Nrog rau txoj kev loj hlob ntawm cov cuab yeej ntse, yuav yeej tsav lub LCD kev lag luam motherboard tawg loj hlob.
Feem ntau ntawm cov tam sim no mainstream LCD motherboard vuam txheej txheem yog tseem siv cov tsoos phau ntawv soldering hlau vuam txheej txheem, siab zog nqi, qeeb zus tau tej cov efficiency, cov tsoos vuam txheej txheem coj mus rau ib tug poob rau hauv cov khoom tsim nyog tus nqi. Tsis siv neeg kub tswj laser vuam tshuab zoo kawg nkaus daws qhov teeb meem ntawm cov khoom loj ntawm LED motherboards.
Laser vuam txoj kev
LCD motherboard laser vuam tshuab heats saum npoo ntawm lub workpiece los ntawm laser hluav taws xob, thiab cov nplaim hluav taws xob kis mus rau sab hauv los ntawm kev siv hluav taws xob. Los ntawm kev tswj cov tsis muaj laser mem tes dav, lub zog, ncov lub zog thiab rov ua dua zaus, lub workpiece melts thiab tsim ib lub pas dej ua ke tshwj xeeb. Vim nws qhov tshwj xeeb zoo, nws tau ua tiav hauv kev siv vuam ntawm micro thiab me me thiab vuam ntawm nyias-walled daim hlau.
LCD motherboard laser vuam txheej txheem
LCD motherboard laser vuam tshuab tom qab cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob tau sib sau ua ke thiab mus rau hauv qhov chaw nres tsheb vuam, nyob rau hauv kev tswj ntawm tus maub los, thawj qhov khoom siv rau kev pom qhov muag ntawm qhov vuam txoj hauj lwm, thiab tom qab ntawd los ntawm tin feeding mechanism txav lub solder. mus rau qhov saum toj no-hais welding txoj hauj lwm, lub laser welder emits laser mus rau vuam txoj hauj lwm thiab pib cua sov, thaum lub kub maub los saib xyuas qhov vuam txoj hauj lwm, ntsuas qhov kub ntawm lub solder tom qab raug irradiated los ntawm lub laser Thaum lub kub nce saum toj no. melting kub ntawm lub solder, lub solder feeder pib pub lub solder ntawm lub teeb ceev, thaum lub kub maub los saib xyuas lub soldering kub, thiab thaum lub soldering kub siab tshaj qhov kub thiab txias, cov zis zog ntawm lub laser welder yog txo los ntawm. tus maub los, thiab thaum lub soldering kub yog qis dua qhov kub ntawm lub teeb, lub zog tso zis ntawm lub laser welder yog nce, yog li ntawd lub soldering kub yog ib txwm khaws cia nyob rau hauv lub teeb cheeb tsam los mus tiv thaiv qhov kub thiab txias los ntawm kub kub yog ib txwm. khaws cia rau hauv thaj chaw teeb tsa kom tsis txhob muaj kev puas tsuaj rau cov khoom ua haujlwm yog tias qhov kub thiab txias siab dhau lawm thiab tiv thaiv kev vuam los ntawm kev ua tiav yog tias qhov kub thiab txias qis dhau.
Tin pob laser vuam txheej txheem
Vim tias laser vuam tsuas yog ua kom sov qhov kev sib txuas hauv zos, tsis muaj qhov cuam tshuam thermal ntawm lub cev tiv thaiv, thiab cua sov thiab cua txias ceev ceev, qhov sib koom ua ke tau zoo thiab txhim khu kev qha. Nyob rau tib lub sijhawm, laser solder pob welding tsis yog kev sib cuag, tsis muaj kev ntxhov siab los ntawm kev siv vuam tsoos, tsis muaj hluav taws xob zoo li qub, zoo heev rau cov khoom siv nrog thermal cuam tshuam. Rau cov khoom me me, laser ua precision, laser qhov chaw tuaj yeem ncav cuag qib micron, lub sijhawm ua haujlwm / lub zog tswj kev tswj hwm, kev ua haujlwm raug ntau dua li cov tsoos hlau soldering thiab HOT BAR soldering, siv me me laser beam es tsis txhob soldering hlau taub. , nyob rau hauv ib qho chaw me me kuj tuaj yeem ua haujlwm thiab lwm yam zoo, yog li cov txheej txheem laser soldering tuaj yeem siv dav hauv LCD motherboards thiab lwm yam khoom siv hluav taws xob kev lag luam.
