32 txheej Circuit Court boards, nrog rau lawv cov peev xwm sib koom ua ke muaj zog, tau siv dav hauv thaj chaw xws li siab -kawg servers, cov khoom siv hluav taws xob hauv aerospace, thiab cov chaw sib txuas lus nyuaj uas xav tau kev ua haujlwm hluav taws xob heev. Thiab nws cov tuab, raws li qhov tseem ceeb ntawm lub cev, tsis tsuas yog cuam tshuam rau kev ua haujlwm ntawm lub tshuab hluav taws xob thiab hluav taws xob ntawm lub rooj tsav xwm hauv Circuit Court nws tus kheej, tab sis kuj muaj kev cuam tshuam loj heev rau tag nrho cov qauv tsim thiab kev npaj cua sov ntawm cov khoom siv.
1, Kev cuam tshuam ntawm cov ntaub ntawv tseem ceeb ntawm cov thickness
(1) Lub luag haujlwm ntawm cov khoom siv substrate
Lub substrate ntawm lub rooj tsav xwm Circuit Court, ua lub hauv paus rau kev nqa cov kab hluav taws xob thiab cov khoom siv hluav taws xob, ua lub luag haujlwm tseem ceeb hauv cov tuab tuab. Cov khoom siv hauv qab feem ntau suav nrog epoxy iav ntaub laminates, ceramic substrates, thiab siab -cov ntaub ntawv ceev ceev uas tau tshwm sim nyob rau xyoo tas los no. Siv dav siv FR-4 substrate ua piv txwv, nws muaj qee qhov tuab tshwj xeeb, nrog cov tuab tuab ntawm 0.2mm-3.2mm. Nyob rau hauv 32 txheej Circuit Court board, siv ib tug thicker FR-4 substrate raws li cov tub ntxhais kev them nyiaj yug yuav undoubtedly nce lub zuag qhia tag nrho thickness. Ceramic substrates, vim lawv cov khoom siv hluav taws xob zoo heev thiab cov thermal conductivity siab, feem ntau yog siv hauv circuits uas xav tau kev ua haujlwm siab heev. Txawm li cas los xij, lawv qhov ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom kuj tuaj yeem ua kom cov tuab tuab ntawm cov khoom siv hluav taws xob.
(2) Kev cuam tshuam ntawm tooj liab ntawv ci thickness
Copper foil, raws li lub ntsiab lus tseem ceeb rau kev ua tiav cov khoom siv hluav taws xob hauv Circuit Court boards, kuj muaj qhov cuam tshuam loj rau tag nrho cov thickness ntawm 32 txheej Circuit Court board vim nws thickness. Feem ntau hais lus, copper foil thickness yog muab faib ua ntau yam specifications xws li 1oz (35 μ m), 2oz (70 μ m), thiab 3oz (105 μ m). Nyob rau hauv 32 txheej Circuit Court board, yog hais tias tej txheej yuav tsum tau nqa loj tam sim no, xws li lub hwj chim txheej, thicker tooj liab foils, xws li 2oz los yog 3oz tooj liab foils, tej zaum yuav siv tau los xyuas kom meej conductivity zoo thiab qis kuj. Qhov nce hauv thickness ntawm txhua txheej ntawm cov ntawv ci tooj liab yuav ua rau qee qhov sib tshooj nrog tag nrho cov thickness ntawm lub rooj tsavxwm.
2, Interlayer rwb thaiv tsev cov ntaub ntawv thiab cov qauv tsim yam tseem ceeb
(1) Qhov tseem ceeb ntawm rwb thaiv tsev txheej thickness
Hauv 32 txheej Circuit Court board, cov ntaub ntawv rwb thaiv tsev yuav tsum tau siv los cais cov khaubncaws sab nraud povtseg kom tsis txhob muaj kev cuam tshuam luv luv. Cov ntaub ntawv siv rwb thaiv tsev feem ntau muaj xws li cov nplooj ntawv kho, thiab lwm yam, nrog lub thickness feem ntau ntawm 0.05mm-0.2mm. Vim muaj coob tus ntawm cov txheej txheem interlayer nyob rau hauv lub 32 txheej Circuit Court board, me ntsis sib txawv nyob rau hauv lub thickness ntawm txhua rwb thaiv tsev cov ntaub ntawv txheej yuav muaj kev cuam tshuam loj rau tag nrho cov thickness tom qab accumulating 31 interlayer rwb thaiv tsev intervals. Yog tias cov ntaub ntawv rwb thaiv tsev tuab yog siv los txhim kho cov rwb thaiv tsev interlayer thiab kev sib cais kev ua haujlwm hauv kev ua kom muaj hluav taws xob ntau dua, lub thickness ntawm lub rooj tsav xwm Circuit Court yuav inevitably nce raws li.
(2) Qhov cuam tshuam ntawm kev tsim qauv tsim
Kev tsim cov txheej txheem stacked ntawm lub rooj tsavxwm Circuit Court kuj yog ib qho tseem ceeb hauv kev txiav txim siab nws thickness. Cov txheej txheem ntawm cov txheej txheem sib txawv ntawm cov txheej txheem sib txawv, xws li teeb liab txheej, lub zog txheej, txheej hauv av, thiab lwm yam, hauv cov txheej txheem stacking yuav cuam tshuam rau tag nrho cov tuab. Piv txwv li, txhawm rau txo cov teeb liab cuam tshuam, nws yuav tsum tau hloov cov teeb liab txheej nrog lub hwj chim txheej thiab hauv av txheej. Cov txheej txheem txheej txheej no yuav xav tau ntau qhov chaw rau kev teeb tsa, yog li ua kom lub thickness ntawm lub rooj tsavxwm. Tsis tas li ntawd, qee qhov kev tsim tshwj xeeb, xws li teeb tsa qhov faus, qhov qhov muag tsis pom, thiab lwm yam ntawm cov txheej txheem hauv cov txheej txheem tshwj xeeb los txuas cov kab hluav taws xob sib txawv, tuaj yeem cuam tshuam cov thickness ntawm lub rooj tsav xwm Circuit Court los ntawm kev ua thiab kev teeb tsa ntawm cov vias. Yog hais tias lub viav vias tsim yog complex thiab yuav tsum tau ntau qhov chaw los xyuas kom meej qhov kev cia siab thiab hluav taws xob kev ua tau zoo ntawm lub viav vias, lub thickness ntawm lub Circuit Court board kuj yuav nce raws li.
3, Feem ntau thickness ranges rau 32 txheej Circuit Court boards
Muab rau hauv tus account ntau yam cuam tshuam, lub thickness ntawm 32 txheej Circuit Court board feem ntau ntog nyob rau hauv ib tug kuj dav ntau yam. Raws li cov qauv tsim thiab tsim cov txheej txheem, lub thickness ntawm 32 txheej Circuit Court board yog kwv yees li ntawm 3.0mm-6.0mm. Txawm li cas los xij, nws yuav tsum tau muab sau tseg tias qhov no tsuas yog ntau yam, thiab qhov tseeb thickness yuav txawv nyob ntawm qhov sib txawv ntawm daim ntawv thov scenarios thiab cov qauv tsim.
Nyob rau hauv qhov siab -kawg neeg rau zaub mov, vim tias qhov kev xav tau siab heev rau kev ruaj ntseg thiab kev ua haujlwm ntawm cov hluav taws xob hluav taws xob, cov ntaub ntawv tuab thiab cov ntaub ntawv tooj liab yuav raug siv, thiab qhov tseem ceeb tshaj plaws yuav raug muab tso rau hauv kev cia siab rau hauv interlayer rwb thaiv tsev thiab cov qauv tsim, uas tej zaum yuav ua rau Circuit Court board thickness leaning ntawm 6.0mm los yog tuab. Hauv qee cov khoom siv hluav taws xob hauv aerospace nrog cov kev txwv nruj ntawm qhov chaw loj, cov kws ua haujlwm yuav ua kom zoo dua cov txheej txheem stacking, xaiv lub teeb yuag substrates thiab cov ntaub ntawv rwb thaiv tsev, thiab tswj lub thickness ntawm 32 txheej Circuit Court board mus txog 3.0mm kom ntau li ntau tau thaum ua tau raws li qhov yuav tsum tau ua hluav taws xob, txhawm rau txo cov khoom hnyav thiab txhim kho qhov chaw siv.
