Cov PCBs ceramic puas kim dua li cov laug cam FR-4 ib txwm muaj?
Yog lawm, cov PCBs ceramic kim dua li cov laug cam FR-4 ib txwm muaj vim tias cov khoom siv ceramic yog cov khoom siv PCB tshiab thiab ua tau zoo dua.
Cov PCB ceramic raug tsim li cas?
Cov hauv qab no yog cov txheej txheem tsim khoom yooj yim rau cov PCBs ceramic.
Npaj cov khoom siv raw → txheej sab hauv tooj liab etching → laminating → drilling → tawm txheej tooj liab kab → solder mask printing → kev kho deg → silkscreen printing → qhib / luv luv kuaj → kev tshuaj xyuas zoo kawg → ntim.
Puas yog Richfulljoy tsim cov PCB ceramic ntau txheej?
Yog, peb muaj kev paub nplua nuj heev hauv kev tsim cov PCB ceramic multilayer. Thov hu rau peb pab neeg muag khoom kom tau txais tus nqi dawb rau koj cov khoom siv ceramic PCB.
Qhov txawv tseem ceeb yog dab tsi: Ceramic pcb vs FR4?
1. Cov substrates txawv;
2. Cov kev siv sib txawv;
3. Tus nqi sib txawv: cov khoom siv tooj liab-clad ceramic substrate kim dua;
4, Txawv hauv kev tsim khoom: cov txheej txheem tsim khoom PCB ceramic nyuaj dua.
Puas muaj tej yam tshwj xeeb uas yuav tsum nco ntsoov thaum tsim ib lub PCB ceramic?
Thaum tsim cov PCBs ceramic, peb yuav tsum tsis txhob saib qhov kev tsim qauv yooj yim thiab yuav tsum nco ntsoov ob peb yam.
Thaum tsim cov PCB ceramic, peb yuav tsum xaiv cov khoom siv dielectric kom zoo rau daim ntawv thov xav tau.
Cov kev tswj hwm impedance yeej ib txwm xav tau hauv cov PCBs ceramic, yog li cov neeg tsim qauv yuav tsum xam tus nqi impedance raws li cov khoom siv (Er), tuab tooj liab, dav tooj liab / qhov chaw, dielectric thickness, thiab lwm yam.
Vim tias cov khoom siv ceramic kim dua li cov khoom siv FR4, kev tsim cov khoom siv ceramic circuit board yuav tsum xav txog tus nqi PCB thiab tus nqi thov tag nrho.
Yog tias peb txheeb xyuas cov teeb meem uas yuav tshwm sim thaum ntxov hauv cov txheej txheem tsim, peb tuaj yeem ua kom muaj kev vam meej hauv cov theem tom qab. Yog tias peb npaj zoo, cov PCB ceramic 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 cov PCB ceramic.
Lub sijhawm ua khoom siv rau kev tsim khoom PCB ceramic yog dab tsi?
Peb lub sijhawm ua cov PCB yog li ntawm 1-3 lub lis piam. Tab sis qee zaum, peb yuav xav tau ob peb lub lis piam los yuav cov khoom siv ceramic tshwj xeeb. Yog li, cov xwm txheej xws li hom khoom siv thiab thev naus laus zis siv rau ntawm PCB yuav txiav txim siab lub sijhawm ua cov khoom siv ceramic PCB.
Tus nqi ntawm ceramic PCB yog dab tsi?
Cov yam hauv qab no txiav txim siab tus nqi ntawm cov PCB ceramic.
Cov khoom siv substrate (qhov tseem ceeb tshaj plaws);
Tus nqi ib pawg;
Kev Siv Tshuab Txheej Txheem, xws li kev dig muag / faus;
Qhov nyuaj hauv kev tsim khoom, xws li kev kam rau siab impedance nruj heev, kev kam rau siab tooj liab dav;
Lwm yam kev cai tshwj xeeb.
Qhov txawv ntawm Ceramic PCB thiab Teflon PCB yog dab tsi?
Cov ntaub ntawv sib txawv:
Teflon yog ib hom khoom siv polyimide, uas yog ib hom yas ua haujlwm siab tshwj xeeb. Tab sis ceramic yog ib hom tshuaj ua los ntawm boron nitride, beryllium oxide thiab silicon carbide.
Cov kev siv muaj ntau yam sib txawv:
Teflon PCBs yeej ib txwm siv rau kev siv microwave thiab RF. Tab sis cov ntaub ntawv ceramic feem ntau yog txhawb nqa nrog kev sib xyaw ua ke ntawm lwm cov ntaub ntawv, yog li cov khoom siv ceramic substrates feem ntau siv dav dua.
Cov txheej txheem tsim PCB thiab cov txheej txheem sib txawv:
Qhov no yog vim tias cov yam ntxwv ntawm ob hom ntaub ntawv sib txawv kiag li.
