Cov Kauj Ruam Xaiv Cov Khoom Siv PCB Zoo
Xaiv Raws Li Zaus
Siv cov ntaub ntawv uas tsis tshua muaj kev poob zoo li Rogers 5880 rau radar zaus siab.
Xaiv cov khoom siv FR-4 uas tau hloov kho rau cov nqi uas tsis tshua muaj nqi, thiab cov ntawv thov uas siv zaus tsawg.
Xav txog qhov yuav tsum tau ua ntawm lub zog thiab thermal
Cov radar muaj zog siab yuav tsum siv cov ntaub ntawv uas muaj kev ua tau zoo dua ntawm cov cua sov, xws li cov laminates uas muaj hlau txhawb nqa.
Sib phim cov xwm txheej ib puag ncig
Cov radars tub rog thiab aerospace tau txais txiaj ntsig los ntawm cov ntaub ntawv kub thiab tiv taus dej noo xws li PTFE lossis polyimide.
Kev Ua Tau Zoo thiab Tus Nqi Sib Npaug
Rau cov haujlwm uas muaj peev nyiaj tsawg, xaiv cov FR-4 hloov kho thaum xyuas kom meej tias nws ua tau raws li cov qauv kev ua tau zoo tseem ceeb.
Cov Yuam Kev Feem Ntau Hauv Kev Xaiv Khoom Siv PCB
Kev vam khom rau ib yam khoom xwb
Cov modules radar sib txawv yuav xav tau cov khoom siv PCB sib txawv. Piv txwv li, RF modules xav tau Rogers, thaum cov modules tswj yuav siv FR-4.
Saib Xyuas Kev Tswj Xyuas Thermal
Txawm tias muaj cov ntaub ntawv ua haujlwm tau zoo, cov qauv tsim cua sov kom zoo yog qhov tsim nyog rau kev ua kom cua sov zoo.
Tsis quav ntsej txog qhov nyuaj ntawm kev tsim khoom
Cov ntaub ntawv ua tau zoo feem ntau xav tau cov peev xwm ua haujlwm tshwj xeeb, yog li xyuas kom koj tus neeg muag khoom tuaj yeem daws cov teeb meem no.
Xaus Lus: Tus yuam sij rau kev ua tau zoo tshaj plaws ntawm Radar PCB
Kev xaiv cov khoom siv PCB zoo yog qhov tseem ceeb rau kev ua kom zoo dua ntawm radar system kev ua haujlwm, kev ntseeg siab, thiab kev siv nyiaj tsawg. Rau cov radar systems uas muaj zaus siab, Rogers thiab Taconic cov khoom siv muaj kev ua tau zoo dua. Rau cov ntawv thov uas xav tau nyiaj tsawg, kev hloov kho FR-4 tuaj yeem muab lwm txoj hauv kev uas pheej yig dua.
Kev koom tes nrog tus neeg tsim khoom PCB uas muaj kev paub dhau los ua kom ntseeg tau tias kev xaiv cov khoom siv thiab kev txhawb nqa kev tsim khoom rau koj cov ntawv thov radar.
