Qhov tseeb Circuit Court ntawm pcb tau dhau los ua ib qho ntawm cov cim tseem ceeb rau kev ntsuas qib kev tsim khoom. Ntawm lawv, kev tsim muaj peev xwm ntawm 3mil kab dav tuaj yeem suav tias yog "kev ua haujlwm zoo" ntawm PCB kev lag luam. Nws tsis yog tsuas yog kev xav txog lub zog ntawm kev txawj ntse, tab sis kuj tseem yog tus yuam sij rau kev txhawb nqa siab -kawg cov khoom siv hluav taws xob kom ua tiav cov haujlwm nyuaj.
Tus nqi tsim nyog thiab daim ntawv thov scenarios ntawm 3mil Kab Dav
Ib txoj kab dav 3mil txhais tau hais tias qhov denser Circuit Court layout tuaj yeem ua tiav ntawm cov ntawv luam tawm Circuits boards, haum rau ntau lub voj voog thiab cov teeb liab raws ntawm tib cheeb tsam ntawm Circuit Board. Qhov no yog lub hauv paus tseem ceeb rau kev ua tiav kev sib koom ua ke rau cov khoom lag luam muaj txiaj ntsig xws li smartphones, cov cuab yeej siv tau zoo, thiab cov cuab yeej kho mob. Piv txwv li, lub siab -kawg smartwatch nrog thaj tsam ntawm motherboard tsuas yog ob peb square centimeters yuav tsum muaj kev sib koom ua ke ntawm kaum ob ntawm cov khoom xws li processors, sensors, thiab wireless kev sib txuas lus modules. Ib tug 3mil kab dav luam tawm circuits boards tuaj yeem ua tiav kev sib txuas hluav taws xob ntawm ntau yam khoom hauv ib qho chaw txwv los ntawm kev sib cog lus, thaum tsis txhob teeb liab cuam tshuam ntawm circuits.
Hauv kev ua haujlwm siab - zaus thiab siab - circuits ceev, kev tswj kom meej ntawm 3mil kab dav yog qhov tseem ceeb rau kev ncaj ncees. Nrog rau qhov nce ntawm cov ntaub ntawv kis tau tus mob, qhov impedance sib piv cov cai ntawm txoj kab tau dhau los ua nruj, thiab txawm tias me ntsis kab dav sib txawv yuav ua rau muaj teeb meem xws li teeb liab xav txog thiab attenuation. Lub peev xwm tsim khoom ruaj khov ntawm 3mil kab dav kom ntseeg tau tias cov kab impedance yog tswj nyob rau hauv ib tug kam rau ua ntau yam ntawm ± 8%, ua tau raws li cov kev cai kis tau tus mob siab - ceev cov cim. Hauv kev tswj cov chips, siab- kawg FPGAs, thiab lwm yam khoom, 3mil kab dav luam tawm circuits boards muab lub cev muaj peev xwm txhim khu kev qha rau siab -kev ua haujlwm ceev ntawm cov logic circuits.
Tsis tas li ntawd, 3mil kab dav siv tshuab kuj tuaj yeem txo cov kev siv hluav taws xob thiab hluav taws xob tsim hluav taws xob ntawm cov ntawv luam tawm ntawm cov boards. Thinner lines have higher resistance at the same current, but in high-density layouts, optimizing the ratio of line width and spacing can reduce line crossing and parasitic capacitance, and instead reduce energy loss during signal transmission. Cov yam ntxwv no ua rau nws siv dav hauv kev tswj hwm roj teeb rau lub zog tshiab tsheb thiab cov khoom siv hluav taws xob sib sib zog nqus rau aerospace.
Core technical support kom ua tiav 3mil kab dav
Kev tsim khoom ntawm 3mil kab dav tsis yog tsuas yog txo cov txheej txheem, tab sis yuav tsum tau ua kom tiav hauv tag nrho cov saw hlau ntawm cov khoom siv, khoom siv rau cov txheej txheem. Hauv kev xaiv cov khoom, qhov flatness thiab seem stability ntawm lub substrate yog lub hauv paus. Kev siv FR-4 nplooj ntawv lossis cov khoom siv zaus nrog Tg siab qhov tseem ceeb (iav hloov pauv kub) tuaj yeem txo cov substrate deformation los ntawm qhov kub thiab txias thaum lub sij hawm ua, kom ntseeg tau qhov tseeb ntawm Circuit Court etching. Meanwhile, lub uniformity ntawm tooj liab ntawv ci thickness kuj tseem ceeb heev. Nyias thiab niaj hnub ntawv ci tooj liab tuaj yeem txo qhov cuam tshuam sab etching thaum lub sij hawm etching txheej txheem thiab xyuas kom meej qhov sib xws ntawm kab dav.
Cov cuab yeej raug yog qhov kho vajtse lav rau kev ua tiav 3mil kab dav. Cov txheej txheem tsim hluav taws xob yuav tsum tau siv LDI thev naus laus zis, uas muaj qhov tseeb qhov chaw ntawm ± 1 μ m thiab tuaj yeem kos cov qauv hauv Circuit Court nrog cov kab dav ntawm 3mil, tsis txhob ua yuam kev los ntawm zaj duab xis ncab hauv cov tshuab raug. Nyob rau hauv cov txheej txheem etching, cov kab acidic etching yuav tsum muaj kev tswj xyuas meej ntawm qhov siab, qhov kub thiab txias, thiab cov tshuaj tsuag lub siab ntawm cov tshuaj etching, kom ntseeg tau tias cov npoo ntawm lub voj voog los ntawm kev sib txawv ntawm cov etching thiab tsis txhob sawtooth lossis hlau tawg. Tsis tas li ntawd, kev sib xyaw ua ke ntawm cov tshuab gong precision thiab cov cuab yeej drilling (nrog rau qhov tsawg kawg nkaus tshuab drilling ntawm 0.15mm thiab laser drilling ntawm 0.1mm) tuaj yeem ua tiav los ntawm - qhov ua tiav hauv cov kab me me, ua tiav cov kev sib txuas sib txuas yam tsis muaj kev puas tsuaj rau cov kab uas nyob ib sab.
Cov txheej txheem tswj yog tus yuam sij rau kev ruaj khov loj ntawm 3mil kab dav. Kev soj ntsuam nruj nruj yuav tsum tau ua nyob rau hauv txhua kauj ruam, los ntawm kev sib xyaw ua ke hauv cov txheej txheem lamination (kev sib txawv yuav tsum tau tswj tsis pub dhau 5 μ m) mus rau qhov sib xws ntawm tooj liab txheej thickness thaum graphic electroplating ( kam rau ua ± 5%). Piv txwv li, nyob rau hauv cov txheej txheem solder daim npog qhov ncauj, siv solder daim npog qhov ncauj DI thev naus laus zis es tsis txhob siv tshuaj ntsuam luam ntawv tuaj yeem tswj tau qhov qhib ntawm lub npog ntsej muag, tsis txhob npog lub voj voog lossis nthuav tawm lub substrate vim yog lub npog ntsej muag offset. Nyob rau tib lub sijhawm, txoj kab dav tuaj yeem ntsuas lub sijhawm tiag tiag los ntawm anime tester, metallographic microscope thiab lwm yam khoom siv kom paub tseeb tias qhov tseeb ntawm txhua pawg ntawm cov khoom ua tau raws li qhov yuav tsum tau ua.
Yuav tsum muaj kev tswj hwm ntau lawm hauv 3mil Kab Dav Kev Tsim Khoom
Kev tsim cov ntawv luam tawm cov ntawv luam tawm nrog cov kab dav ntawm 3mil yuav tsum muaj qhov siab tshaj plaws hauv kev tswj hwm ntau lawm. Hauv qhov kev txiav txim ua theem, cov tshuab ntse yuav tsum tau teb sai sai rau cov kev tshawb xyuas tsis yooj yim. Los ntawm kev tshawb xyuas cov cuab yeej ntse zoo ib yam li Iprinted circuits boards system, cov tsis tseem ceeb xws li phaj tuab, cov txheej txheem, thiab kev kho saum npoo sib haum rau 3mil kab dav hauv kev txiav txim tuaj yeem raug txheeb xyuas, cov txheej txheem muaj peev xwm tuaj yeem ntsuas tau, thiab muaj peev xwm raug kwv yees, xws li kev sib tw ntawm kab dav thiab aperture tau txais kev txiav txim siab tsis muaj dej hiav txwv.
Nyob rau hauv cov nqe lus ntawm kev teem sij hawm ntau lawm, cov khoom uas muaj ib tug kab dav ntawm 3mil yuav tsum tau txais ib tug mob siab rau ntau lawm hom kom tsis txhob parameter cuam tshuam los ntawm kev sib koom cov cuab yeej nrog zoo tib yam kab dav khoom. Piv txwv li, nyob rau hauv kev siv cov etching kab, nws yog ib qhov tsim nyog los cais lub sij hawm etching thiab tshuaj tsuag siab tsis sib haum mus rau ib tug 3mil kab dav, thiab sau cov ntaub ntawv ua ntawm txhua lub rooj tsavxwm los ntawm ib tug tiag tiag - lub sij hawm soj ntsuam system kom ua tiav tag nrho traceability. Nyob rau tib lub sijhawm, 24-teev kev soj ntsuam xyuas zoo yuav raug tsim los ua 100% kev tshuaj xyuas cov kab siv txuas nrog AOI thev naus laus zis, tshawb xyuas qhov tsis xws li kab dav sib txawv, luv Circuit Court, thiab qhib Circuit Court, thiab tswj qhov tsis xws luag ntawm qib ppm.
Kev xa khoom muaj peev xwm kuj yog qhov tseem ceeb rau kev ntsuas kev tsim khoom ntawm 3mil kab dav. Vim yog qhov nyuaj ntawm cov txheej txheem, lub voj voog ntau lawm ntawm cov ntawv luam tawm Circuit Court boards nrog 3mil kab dav feem ntau yog ntev dua li cov khoom lag luam. Txawm li cas los xij, los ntawm kev ua kom zoo ntawm cov txheej txheem tsim khoom, xws li siv "cov qauv qhia" cov kev pabcuam, kev xa khoom sai ntawm cov khoom me thiab nruab nrab- qhov loj me tuaj yeem ua tiav. Piv txwv li, lub sij hawm xa khoom siab tshaj plaws rau 2-txheej boards tuaj yeem compressed rau 24 teev, thiab rau 4-txheej boards rau 48 teev. Qhov no tso siab rau lub sijhawm hloov pauv ntawm cov kab tsim khoom ntse thiab cov lus teb tam sim ntawm cov pab pawg engineering kom ntseeg tau tias cov neeg siv khoom tuaj yeem tau txais cov qauv sai sai uas ua tau raws li qhov yuav tsum tau ua hauv kev tshawb fawb thiab kev tsim kho mus sib hais.
Kev lag luam tseem ceeb thiab yav tom ntej nthuav dav ntawm 3mil Kab Dav Technology
Kev ua tiav hauv kev tsim muaj peev xwm ntawm 3mil kab dav tsis tsuas yog txhim kho kev lag luam kev sib tw ntawm cov ntawv luam tawm Circuits boards cov lag luam, tab sis kuj txhawb kev txhim kho ntawm tag nrho cov khoom siv hluav taws xob. Nws muab kev txhawb nqa rau hauv cheeb tsam ntawm siab -kawg cov khoom xws li nti ntim substrates thiab HDI boards, rhuav tshem lub monopoly ntawm txawv teb chaws nyob rau hauv lub teb ntawm precision printed circuits boards. Hauv cov chaw tawm tshiab xws li 5G lub hauv paus chaw nres tsheb, cov neeg ua haujlwm txawj ntse, thiab kev tsav tsheb tsis muaj zog, cov ntawv luam tawm Circuit Court boards nrog 3mil kab dav tau dhau los ua "tsis pom tus phab ej" hauv kev txhim kho cov cuab yeej ua haujlwm.
