4 Txheej ENIG RO4350 High Frequency PCB
Rogers 4350 PCB Chaw tsim tshuaj paus
Rogers RO4350B siab zaus PCB yog patented woven iav daim ntaub reinforced hydrocarbon resin system / ceramic muab tub lim khoom, nws cov khoom hluav taws xob yog ze heev rau PTFE / woven iav ntaub ntaub thiab machinability zoo ib yam li epoxy resin / iav ntaub ntaub.
Rogers RO4350B siab zaus PCB lub rooj tsavxwm tuaj yeem ua tiav siv cov txheej txheem epoxy / iav ntaub, thaum muab nruj tswj kev tso cai thiab poob ntawm ib feem ntawm tus nqi ntawm cov khoom siv hauv microwave.Muaj txawm tias tsis xav tau tshwj xeeb los ntawm lub qhov ua ntej lossis cov txheej txheem ua haujlwm xws li cov ntaub ntawv microwave raws li microwave RF PCB PTFE.
Rogers RO4350B siab zaus PCB cov khoom siv tau dhau los ntawm UL 94V-0 qhov hluav taws kub xav tau rau cov khoom siv nquag thiab cov khoom siv hluav taws xob siab microwave RF board tsim.
Cov txiaj ntsig ntawm Rogers 4350 High Frequency PCB
Rogers RO4350B yog hydrocarbon / ceramic laminate nrog dielectric tas li ntawm 3.48.Nws ua tau raws li qhov yuav tsum tau ua ntawm cov khoom lag luam qib khoom lag luam rau cov ntawv luam tawm Circuit Board.
Nws muaj qhov zoo hauv qab no:
1. Tsawg RF poob
2. Tsawg permittivity fluctuates nrog kub
3. Tsawg Z-axis thermal expansion coefficient
4. Tsawg hauv-phaj expansion coefficient
5. Tsawg permittivity kam rau ua
6. Cov yam ntxwv hluav taws xob ruaj khov ntawm ntau zaus
7. Yooj yim rau huab hwm coj ntau lawm thiab FR4 ntau txheej sib xyaw, kev ua haujlwm siab
Qhov zoo ntawm Rogers 4350 PCB
Zoo impedance tswj
Nrog qis dielectric poob, tsis tshua muaj teeb liab poob
Haum rau hnyav ib puag ncig
Nws yog tus nqi zoo heev hauv kev tsim khoom siv hluav taws xob
Rogers PCB tau pom qhov nqus dej tsawg dua thiab txhim kho kev tswj xyuas thermal
Lub coefficient ntawm thermal expansion ntawm RO4000 cov khoom yog zoo ib yam li cov tooj liab, uas muab qhov ntev stability.
