Rogers PCB board series kev faib tawm yog dab tsi?

Cov khoom siv Rogers RO4350B tso cai rau RF PCB engineers kom yooj yim tsim circuits, xws li kev sib koom ua ke hauv network thiab impedance tswj cov kab sib kis.Vim nws cov yam ntxwv tsis tshua muaj dielectric poob, RO4350B cov khoom muaj qhov zoo sib xws ntawm cov khoom siv hluav taws xob zoo tib yam hauv cov ntawv siv ntau zaus.Qhov sib txawv ntawm permittivity nrog kub yog yuav luag qis tshaj ntawm cov ntaub ntawv zoo sib xws, thiab nws cov permittivity kuj tseem ruaj khov nyob rau hauv ntau zaus, nrog rau kev pom zoo tsim ntawm 3.66.LoPra ™ Copper foil txo qis kev nkag.Qhov no ua rau cov khoom tsim nyog rau kev siv broadband.

Rogers PCB pawg thawj coj saibCov khoom siv ceramic siab zaus PCB series kev faib tawm:

RO3000 series: PTFE Circuit Court khoom raws li ceramic filling, qauv yog: RO3003, RO3006, RO3010, RO3035 high-frequency laminate.

RT6000 series: raws li cov khoom siv hluav taws xob uas muaj PTFE, tsim los rau cov khoom siv hluav taws xob thiab microwave circuits uas yuav tsum tau muaj siab permittivity.Cov qauv yog: RT6006 permittivity 6.15, RT6010 permittivity 10.2.

TMM series: cov ntaub ntawv sib xyaw raws li ceramic, hydrocarbon, thermosetting polymer, qauv: TMM3, TMM4, TMM6, TMM10, TMM10i, TMM13i., lwm.
Cov khoom siv RO4003 tuaj yeem raug tshem tawm nrog cov pa nylon txhuam.Tsis muaj kev tuav tshwj xeeb ua ntej electroplating tooj liab tsis muaj hluav taws xob.Lub phaj yuav tsum tau kho siv cov txheej txheem epoxy / iav.Feem ntau, nws tsis tas yuav tshem tawm qhov borehole vim tias lub siab TG resin system (280 ° C + [536 ° F]) tsis muaj xim yooj yim thaum lub sijhawm drilling.Yog tias qhov stain yog tshwm sim los ntawm kev ua haujlwm nruj heev, cov resin tuaj yeem raug tshem tawm siv tus qauv CF4 / O2 plasma voj voog lossis los ntawm cov txheej txheem dual alkaline permanganate.

Kev ua noj ua haus ntawm cov khoom siv RO4000 yog piv rau cov epoxy / iav.Feem ntau, cov khoom siv uas tsis ua noj epoxy / iav phaj tsis tas yuav ua noj RO4003 PCBs.Rau epoxy / ci iav installation ua ib feem ntawm cov txheej txheem tsis tu ncua, peb pom zoo ua noj ntawm 300 ° F, 250 ° F (121 ° C-149 ° C) rau 1 mus rau 2 teev.RO4003 tsis muaj cov nplaim hluav taws.To taub, daim hlau encapsulated nyob rau hauv infrared (IR) units los yog kev khiav hauj lwm ntawm tsawg kis ceev yuav ncav cuag kub tshaj 700 ° F (371 ° C);RO4003 tuaj yeem pib hlawv ntawm qhov kub siab no.Cov tshuab uas tseem siv cov cuab yeej infrared reflux lossis lwm yam khoom siv uas tuaj yeem ncav cuag qhov kub siab no yuav tsum tau ceev faj kom tsis txhob muaj kev pheej hmoo.

Ro3003 yog Rogers PCB board cov khoom siv ceramic ntim PTFE sib xyaw rau kev lag luam microwave thiab RF daim ntaub ntawv.Cov khoom lag luam no yog tsim los muab cov khoom siv hluav taws xob zoo tshaj plaws thiab kev ruaj ntseg ntawm tus nqi sib tw.Rogers Ro3003 muaj kev ruaj ntseg zoo tshaj plaws nyob rau hauv tag nrho qhov kub thiab txias, suav nrog kev tshem tawm cov kev hloov pauv uas tshwm sim thaum PTFE iav cov ntaub ntawv siv nyob rau hauv chav tsev kub.Tsis tas li ntawd, Ro3003 laminates tau poob coefficients qis li 0.0013 txog 10 GHz.
