Puas yog ceramic PCBs kim dua li FR-4 boards?
Yog lawm, ceramic PCBs yog kim dua li cov tsoos FR-4 boards vim cov ceramic substrate yog ib qho tshiab thiab superior-kev ua tau zoo ntawm cov khoom siv PCB.
Yuav ua li cas yog ceramic PCBs tsim?
Hauv qab no yog cov txheej txheem tsim khoom yooj yim rau ceramic PCBs.
Npaj cov khoom siv raw → puab txheej tooj liab kab etching → laminating → drilling → tawm txheej tooj liab kab → solder mask printing → nto kho → silkscreen printing → qhib / luv xeem → zaum kawg kev soj ntsuam zoo → ntim.
Puas yog Richfulljoy tsim multilayer ceramic PCB?
Yog lawm, peb muaj kev nplua nuj heev hauv kev tsim cov ceramic multilayer PCB. Thov hu rau peb pab neeg muag khoom kom tau txais daim ntawv tso cai pub dawb rau koj cov khoom siv ceramic PCB.
Dab tsi yog qhov sib txawv tseem ceeb: Ceramic pcb vs FR4?
1. Cov substrates txawv;
2. Cov kev siv sib txawv;
3. Cov nqi sib txawv: tooj liab-clad ceramic substrate yog kim dua;
4, Kev sib txawv hauv kev tsim khoom: cov txheej txheem tsim khoom ceramic PCB yog qhov nyuaj dua.
Puas muaj tej yam tshwj xeeb uas yuav tsum nco ntsoov thaum tsim cov ceramic PCB?
Thaum tsim cov ceramic PCBs, peb yuav tsum tsis txhob coj tus qauv tsim maj mam thiab yuav tsum khaws ntau yam kev xav hauv siab.
Thaum tsim cov ceramic PCB, peb yuav tsum ua tib zoo xaiv cov khoom siv dielectric rau daim ntawv thov uas xav tau.
Tswj impedance yog ib txwm xav tau nyob rau hauv ceramic PCBs, yog li cov neeg tsim qauv yuav tsum xam cov nqi impedance raws li cov khoom siv (Er), tooj liab thickness, tooj liab dav / qhov chaw, dielectric thickness, thiab lwm yam.
Txij li cov khoom siv ceramic yog kim dua li cov khoom siv FR4, cov khoom siv hluav taws xob ceramic tsim yuav tsum xav txog tus nqi PCB thiab tag nrho cov nqi ntawm daim ntawv thov.
Yog tias peb txheeb xyuas cov teeb meem uas yuav tshwm sim thaum ntxov ntawm tus txheej txheem tsim, peb tuaj yeem ua kom muaj kev vam meej nyob rau theem tom ntej. Nrog kev npaj ua tib zoo, ceramic PCBs tuaj yeem muab cov kev daws teeb meem zoo rau ntau yam kev siv. Thov hu rau peb dawb yog tias koj muaj lus nug txog ceramic PCBs.
Lub sijhawm ua haujlwm rau ceramic PCB yog dab tsi?
Peb lub sij hawm ua tus qauv rau PCB ntau lawm yog nyob ib ncig ntawm 1-3 lub lis piam. Tab sis qee zaum, peb yuav xav tau ob peb lub lis piam mus yuav cov khoom siv ceramic tshwj xeeb. Yog li, cov xwm txheej zoo li cov khoom siv thiab thev naus laus zis siv ntawm PCB yuav txiav txim siab lub sijhawm ua haujlwm rau cov khoom siv ceramic PCB.
Tus nqi ntawm ceramic PCB yog dab tsi?
Cov yam hauv qab no txiav txim siab tus nqi ceramic PCB.
Cov khoom siv substrate (qhov tseem ceeb tshaj plaws);
Muaj pes tsawg leeg ib batch;
Txheej Txheem Technology, xws li qhov muag tsis pom / faus vias;
Nyuaj hauv kev tsim khoom, xws li nruj impedance kam rau ua, nruj tooj liab dav kam rau ua;
Lwm yam kev cai tshwj xeeb.
Dab tsi yog qhov txawv ntawm Ceramic PCB thiab Teflon PCB?
Cov ntaub ntawv sib txawv:
Teflon yog ib yam khoom siv polyimide, uas yog ib hom tshwj xeeb ntawm cov yas ua haujlwm siab. Tab sis ceramic yog ib hom kev sib xyaw ua los ntawm boron nitride, beryllium oxide thiab silicon carbide.
Kev siv yog txawv:
Teflon PCBs yeej ib txwm siv rau microwave thiab RF daim ntaub ntawv. Tab sis cov ntaub ntawv ceramic feem ntau yog siv nrog kev sib xyaw ua ke ntawm lwm cov ntaub ntawv, yog li ceramic substrates tau dav siv ntau dua.
PCB ntau lawm txheej txheem thiab cov txheej txheem yog txawv:
Qhov no yog vim hais tias cov yam ntxwv ntawm ob hom khoom sib txawv kiag li.
