High impedance Circuit Court boards muaj ntau daim ntawv thov nyob rau hauv siab -kawg teb xws li kev sib txuas lus, aerospace, khoom kho mob, thiab lwm yam. vim lawv cov hluav taws xob ua tau zoo heev. Los ntawm cov teeb liab sib kis ntawm 5G hauv paus chaw nres tsheb mus rau kev ua haujlwm zoo ntawm avionics systems mus rau qhov chaw electromagnetic complex, siab impedance Circuit Court boards ua lub luag haujlwm tseem ceeb.
1, Cov khoom siv tshwj xeeb tsim nqi pob zeb
Tus nqi ntawm cov khoom siv yog lub hauv paus tseem ceeb ntawm tus nqi siab impedance Circuit Court boards. Yuav kom ua tau raws li qhov xav tau nruj ntawm qhov poob qis thiab kev ruaj ntseg siab hauv cov teeb liab kis tau tus mob vim muaj cov yam ntxwv ntawm impedance siab, cov khoom siv tshwj xeeb substrate yuav tsum tau xaiv. Piv txwv li, nyob rau hauv siab - zaus thiab siab - kev sib txuas lus ceev xwm txheej, feem ntau siv Rogers cov ntaub ntawv tau dhau los ua qhov kev xaiv zoo tshaj plaws rau kev ua kom siab siab - ceev thiab ruaj khov teeb liab kis tau tus mob vim lawv tsis tshua muaj dielectric tsis tu ncua thiab dielectric poob. Tab sis cov ntaub ntawv no kim heev, thiab piv rau FR-4 substrates zoo tib yam, tus nqi yuav yog ob peb zaug lossis ntau dua kaum zaus. Nyob rau hauv high impedance Circuit Court boards siv nyob rau hauv 5G lub hauv paus chaw nres tsheb, yog Rogers 4350B khoom siv, substrate nqi tej zaum yuav 5-10 npaug ntawm zoo tib yam FR-4 substrates.
Ntxiv nrog rau cov substrates, cov khoom siv hluav taws xob kuj tseem muaj feem cuam tshuam rau cov nqi. High purity tooj liab ntawv ci yog qhov kev xaiv rau siab impedance Circuit Court boards vim nws zoo heev conductivity thiab tsawg kuj. Nrog rau kev hloov pauv ntawm tus nqi tooj liab hauv kev lag luam thoob ntiaj teb, tus nqi ntawm cov khoom siv hluav taws xob kuj hloov pauv. Thaum tus nqi tooj liab nce siab heev, tus nqi ntawm cov ntawv ci tooj liab nyob rau hauv siab impedance Circuit Court boards tuaj yeem suav txog 30% -40% ntawm tag nrho cov nqi khoom, nce nqi tag nrho.
2, Cov txheej txheem nyuaj tsav cov nqi tsim khoom
Cov complexity thiab siab yuav tsum tau ntawm cov txheej txheem tsim khoom ntxiv tsav tus nqi ntawm siab impedance Circuit Court boards. Nws muaj cov kev xav tau siab heev rau cov kab raug, qhov raug, thiab kev sib txuam sib luag. Siv cov txheej txheem tsim hluav taws xob zoo ua piv txwv, cov kab dav thiab qhov sib txawv ntawm cov kab hluav taws xob zoo tib yam tuaj yeem nyob nruab nrab ntawm 10-15 mil, thaum lub siab impedance Circuit Court boards feem ntau yuav tsum ncav cuag 3-5 mil lossis qis dua. Qhov no yuav tsum tau siv cov thev naus laus zis lithography, xws li laser imaging ncaj qha, uas yog kim thiab muaj kev khiav hauj lwm siab thiab tu nqi.
Nyob rau hauv cov txheej txheem drilling, rau qhov me me (nrog ib txoj kab uas hla tsawg dua 0.15mm) thiab qhov nrog qhov loj nam piv, siab - CNC drilling cov cuab yeej thiab cov cuab yeej tshwj xeeb yuav tsum tau ua. Cov txheej txheem drilling yog lub sijhawm-siv thiab cov khoom seem yog qhov siab, uas ua rau muaj kev nce nqi ntau ntxiv. Cov txheej txheem lamination ntawm ntau- txheej txheej siab impedance Circuit Court boards yuav tsum tau nruj me ntsis kom ntseeg tau cov hluav taws xob sib txuas ntawm cov khaubncaws sab nraud povtseg, ruaj khov teeb liab kis tau tus mob, thiab tswj kom zoo dua qhov tseeb ntawm lamination kub, siab, thiab lub sijhawm. Qhov no undoubtedly nce qhov nyuaj thiab nqi peev ntawm cov txheej txheem.
3, Kev tshawb nrhiav thiab kev txhim kho kev sim ua kom cov khoom lag luam nce nqi
Kev txhim kho thiab kev sim cov nqi ntawm cov khoom siv hluav taws xob siab impedance yuav tsum tsis txhob kwv yees. Vim muaj kev ua tau zoo heev hauv daim ntawv thov teb, ntau tus neeg ua haujlwm, cov khoom siv, thiab lub sijhawm yuav tsum tau los ntawm kev tsim hluav taws xob thaum ntxov mus rau kev xaiv cov khoom siv, thiab tom qab ntawd ua cov txheej txheem parameter optimization. Pab pawg kws tshaj lij engineering yuav tsum tau mus dhau ntau qhov kev sim rov ua dua thiab ua kom zoo dua txhawm rau txhawm rau tsim lub rooj tsav xwm hluav taws xob uas ua tau raws li qhov ntsuas kev ua tau zoo. Thaum txhim kho lub siab impedance Circuit Court boards rau 5G kev sib txuas lus hauv paus chaw nres tsheb, kev tshawb fawb thiab kev loj hlob lub voj voog yuav siv sij hawm txog 1-2 xyoos, suav nrog ntau tus nqi xws li R&D cov nyiaj hli cov neeg ua haujlwm, kev siv cov khoom siv, cov khoom siv, thiab lwm yam. Cov nqi no thaum kawg yuav muab faib rau cov khoom lag luam.
Tom qab cov khoom tiav lawm, nws tseem yuav tsum tau kuaj xyuas nruj, xws li kev ntsuas impedance, kev ntsuas kev ntseeg siab, kev ntsuas kev ntseeg tau, thiab lwm yam. Cov khoom siv ntsuas ntsuas siab yog kim, thiab cov txheej txheem kev sim yog qhov nyuaj thiab lub sijhawm-siv, ntxiv cov nqi khoom ntxiv.
4, Kev lag luam khoom muag thiab kev thov cuam tshuam rau tus nqi sib txawv
Kev lag luam kev lag luam thiab kev xav tau kev sib raug zoo muaj feem cuam tshuam rau tus nqi siab impedance Circuit Court boards. Ntawm qhov kev thov sab, nrog kev txhim kho sai ntawm cov thev naus laus zis tshiab xws li 5G, kev txawj ntse, thiab Is Taws Nem ntawm Yam, qhov kev thov rau siab impedance Circuit Court boards tseem nce ntxiv. Kev loj hlob tawg nyob rau hauv tus naj npawb ntawm 5G lub hauv paus chaw nres tsheb tsim tau tsav qhov kev thov tseem ceeb rau cov khoom siv hluav taws xob siab impedance hauv cov khoom siv tseem ceeb ntawm cov chaw nres tsheb.
Txawm li cas los xij, ntawm cov khoom lag luam, vim muaj cov thev naus laus zis thev naus laus zis rau kev tsim cov khoom siv hluav taws xob siab impedance, muaj cov lag luam txwv nrog loj - nplai ntau lawm. Nyob rau tib lub sijhawm, kev ruaj ntseg ntawm cov khoom siv raw khoom tseem cuam tshuam rau kev tsim khoom. Piv txwv li, kev xa khoom ntawm qee qhov siab - cov khoom siv hauv qab kawg yog cuam tshuam los ntawm cov xwm txheej xws li cov xwm txheej thoob ntiaj teb thiab cov khoom siv raw khoom tsim kev lag luam muaj peev xwm txwv, ua rau cov khoom tsis txaus thiab ua rau cov khoom hnyav ntxiv - qhov xav tau tsis txaus, tsav cov nqi.
