Nyob rau hauv lub hauv paus ntsiab lus ntawm cov khoom siv hluav taws xob, cov ntawv luam tawm Circuit Court boards zoo li cov kev sib txuas ntawm neural, nqa cov teeb liab xa mus thiab lub zog ntawm cov khoom siv hluav taws xob. Nrog rau txoj kev loj hlob sai ntawm cov tshuab hluav taws xob rau kev ua haujlwm me me thiab kev ua haujlwm siab, ntau hom ntawv luam tawm Circuit Board tau tshwm sim - HDI board. Muaj qhov sib txawv tseem ceeb ntawmHDI boardsthiab cov ntawv luam tawm zoo tib yam hauv ntau yam, uas cuam tshuam rau kev ua haujlwm thiab kev loj hlob ntawm cov khoom siv hluav taws xob.
Txhais thiab cov qauv sib txawv
Ib qho pcb niaj hnub yog lub rooj tsav xwm luam tawm uas tsim cov ntsiab lus - mus rau - taw tes kev sib txuas thiab cov khoom luam tawm ntawm cov khoom siv insulating raws li tus qauv tsim ua ntej. Nws cov qauv yog qhov yooj yim, feem ntau yog ua los ntawm tooj liab- clad laminates los ntawm kev drilling, circuit etching, electroplating thiab lwm yam txheej txheem. Qhov kev teeb tsa hauv Circuit Court thiab ntawm kev teeb tsa yog qhov sib piv, haum rau cov khoom siv hluav taws xob uas tsis tshua muaj kev xav tau rau qhov chaw thiab kev ua haujlwm.
Thiab HDI pawg thawj coj saib xyuas qhov siab - kev sib txuas ceev ceev. Nws siv cov tshuab microporous thiab cov txheej txheem siab heev xws li laser drilling kom ua tiav cov hluav taws xob sib txuas ntau dua hauv qhov chaw me me. HDI boards feem ntau muaj thinner substrates thiab finer circuits, nrog rau cov khaubncaws sab nraud povtseg, uas muaj peev xwm integrate ntau zog nyob rau hauv tsawg qhov chaw thiab zoo heev txhim khu kev koom ua ke ntawm electronics.
Kev sib piv ntawm cov txheej txheem ntau lawm
Drilling txheej txheem
Ordinary pcb drilling feem ntau siv cov txheej txheem drilling, qhov twg lub laum me ntsis tig rau ntawm tooj liab -clad board los laum qhov xav tau lub qhov taub. Txawm hais tias txoj kev no muaj tus nqi qis dua, qhov aperture kuj loj, feem ntau siab dua 0.3mm, thiab rau siab -precision drilling ntawm ntau- txheej boards, deviations yog feem ntau tshwm sim.
HDI boards dav siv laser drilling tshuab, uas siv high -lub zog ceev laser beams tam sim ntawd yaj los yog vaporize lub rooj tsavxwm los tsim micropores, nrog pore loj npaum li 0.1 hli los yog txawm me dua. Laser drilling muaj qhov ua tau zoo heev thiab tuaj yeem ua tiav cov hom tshwj xeeb xws li qhov muag tsis pom (tsuas yog txuas cov txheej sab nrauv thiab sab hauv) thiab faus qhov (txuas cov txheej sab hauv thiab sab hauv), txhim kho qhov yooj yim thiab ceev ntawm kev sib txuas hauv Circuit Court.
Kab etching txheej txheem
Ordinary printed circuit boards muaj kev txwv tsis pub tshaj kab dav thiab qhov sib nrug thaum etching circuits, nrog rau kab dav / qhov sib nrug ntawm ib ncig ntawm 0.2mm / 0.2mm. Thaum lub sij hawm etching txheej txheem, nws yog ib qho yooj yim mus ntsib teeb meem xws li ntxhib npoo thiab cov kab tsis sib xws ntawm Circuit Court, uas yuav cuam tshuam rau qhov zoo ntawm cov teeb liab kis tau tus mob.
Kev tsim cov HDI boards yuav tsum tau muaj siab precision nyob rau hauv Circuit Court etching, thiab advanced HDI board ntau lawm kab tuaj yeem ua tiav cov kab nrog kab dav / qhov sib nrug tsawg li 0.05mm / 0.05mm lossis txawm tias zoo dua circuits. Los ntawm kev siv cov khoom raug raug ntau dua thiab cov txheej txheem etching, peb xyuas kom meej tias cov npoo ntawm lub voj voog zoo huv si thiab cov kab dav tsis sib xws, ua tau raws li qhov yuav tsum tau ua kom nruj rau Circuit Court zoo hauv siab - ceev thiab siab - zaus teeb liab kis tau tus mob.
txheej txheem lamination
Cov txheej txheem lamination ntawm cov pcb zoo tib yam feem ntau cuam tshuam nrog kev sib txuas ntau txheej ntawm tooj liab- clad laminates ua ke los ntawm kev kub nias, nrog rau kev ua kom ntseeg tau qhov kev sib txuas yooj yim ntawm txhua txheej. Thaum lub sij hawm lamination txheej txheem, qhov yuav tsum tau rau interlayer alignment raug yog kuj tsawg.
Vim nws ntau txheej txheej thiab cov qauv nyuaj, HDI boards yuav tsum nruj heev txheej txheej lamination. Tsis tsuas yog peb yuav tsum ua kom muaj kev sib haum xeeb ntawm txhua txheej, tab sis peb kuj yuav tsum tau ua kom siab -kev sib raug zoo interlayer kom ua tiav qhov kev sib txuas ntawm micro qhov thiab circuits. Thaum lub sij hawm lamination txheej txheem, nws yog ib qho tsim nyog yuav tsum tau tswj xyuas qhov tsis xws li qhov kub thiab txias, siab, thiab lub sij hawm los tiv thaiv qhov tsis xws luag xws li interlayer hloov chaw thiab npuas, kom ntseeg tau tias tag nrho cov kev ua tau zoo ntawm HDI boards.
Qhov sib txawv ntawm kev ua haujlwm zoo
Kev ua haujlwm hluav taws xob
Ordinary printed circuit boards muaj qee yam kev txwv hauv cov teeb liab kis ceev thiab zaus. Raws li lub teeb liab zaus nce, teeb meem xws li teeb liab attenuation thiab crosstalk maj mam ua qhov tseem ceeb. Qhov no yog vim hais tias nws cov Circuit Court tuab thiab loj dua ntawm qhov yuav ua kom muaj zog tiv thaiv, inductance, thiab capacitance, cuam tshuam rau kev ncaj ncees ntawm cov teeb liab.
HDI boards, nrog rau lawv cov intricate Circuit Court thiab micro qhov tsim, zoo heev txo Circuit Court kuj, inductance, thiab capacitance, zoo txo qhov poob thiab cuam tshuam thaum lub teeb liab kis tau tus mob. Nws ua tau zoo heev nyob rau hauv siab - ceev thiab siab - zaus lub teeb liab kis tau tus mob, thiab muaj peev xwm ua tau raws li cov kev xav tau siab heev rau cov teeb liab kis tau tus mob zoo nyob rau hauv daim ntawv thov scenarios xws li 5G kev sib txuas lus thiab siab - ceev cov ntaub ntawv cia.
mechanical zog
Lub zog txhua yam ntawm cov ntawv luam tawm zoo tib yam feem ntau yog nyob ntawm cov khoom siv thiab cov thickness ntawm lub substrate, thiab muaj qee yam fwj hauv miniaturization thiab thinning. Vim nws cov qauv yooj yim, nws muaj feem xyuam rau cov teeb meem xws li phaj deformation thiab weld tawg thaum raug kev nyuaj siab.
HDI boards siv thinner, sib dua, thiab muaj zog substrates, thaum optimizing multi-layer structural tsim los txhim kho tag nrho cov neeg kho tshuab stability. Thaum ua kom lub teeb yuag, nws tuaj yeem tiv taus qee qhov kev ntxhov siab xws li kev co thiab kev cuam tshuam, ua rau nws tsim nyog rau cov teb xws li cov khoom siv hluav taws xob hauv xov tooj ntawm tes uas muaj cov cai nruj rau cov khoom ntim thiab qhov hnyav.
Txawv daim ntawv thov teb
Vim nws cov nqi qis thiab cov txheej txheem tsim khoom yooj yim, cov ntawv luam tawm zoo tib yam tau siv dav hauv cov khoom siv hluav taws xob uas tsis tas yuav muaj kev ua haujlwm siab thiab qhov chaw, xws li cov khoom siv hauv tsev zoo tib yam (xws li TV thiab tshuab ntxhua khaub ncaws), qis- khoom siv hluav taws xob (xws li xov tooj cua zoo tib yam thiab cov chaw taws teeb tswj yooj yim), thiab cov khoom siv hluav taws xob tsis zoo hauv qee yam khoom siv tswj.
HDI boards feem ntau yog siv hauv kev ua haujlwm siab -kawg cov khoom siv hluav taws xob vim lawv qhov kev ua tau zoo heev thiab siab - muaj peev xwm sib xyaw ua ke. Piv txwv li, hauv cov xov tooj ntawm tes, ntau lub zog yuav tsum tau muab tso rau hauv qhov chaw me me, thiab HDI boards tuaj yeem ua tau raws li lawv cov kev xav tau rau siab -ceev teeb liab kis tau tus mob, miniaturization, thiab slimness; Hauv kev ua haujlwm ntawm cov khoos phis tawj, HDI boards tau siv dav rau cov khoom siv xws li server motherboards thiab siab -kawg cov duab kos uas xav tau kev ua haujlwm siab kom ntseeg tau siab - cov ntaub ntawv ceev thiab xa tawm; Tsis tas li ntawd, HDI boards ua lub luag haujlwm tseem ceeb hauv siab - thaj chaw muaj tseeb xws li aerospace thiab cov cuab yeej kho mob, muab kev txhawb nqa rau kev ua haujlwm ruaj khov ntawm cov tshuab hluav taws xob nyuaj.
