4 Txheej ENIG RO4003 + AD255 Mixed Lamination PCB
RO4003C Rogers High zaus PCB cov ntaub ntawv
Cov khoom siv RO4003C 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 hais tias lub siab TG resin system (280 ° C + [536 ° F]) tsis discolor yooj yim thaum lub sij hawm drilling txheej txheem.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.
RO4003C cov ntaub ntawv saum npoo tej zaum yuav yog mechanically thiab / los yog tshuaj npaj rau kev tiv thaiv lub teeb.Nws raug nquahu kom siv cov txheej txheem aqueous lossis semi-aqueous photoresists.Txhua yam khoom siv tooj liab wiper tuaj yeem siv tau.Tag nrho cov filterable los yog yees duab solderable qhov ncauj qhov ntswg feem ntau siv rau epoxy / iav laminates adhere zoo heev rau saum npoo ntawm ro4003C.Kev tu txhua yam ntawm cov khoom siv hluav taws xob raug pom ua ntej siv lub qhov ncauj qhov ntswg thiab cov "sau npe" cov chaw yuav tsum tsis txhob muaj qhov zoo tshaj plaws adhesion.
Kev ua noj ua haus ntawm ro4000 cov ntaub ntawv yog sib npaug rau cov epoxy / iav.Feem ntau, cov khoom siv uas tsis ua noj epoxy / iav phaj tsis tas yuav ua noj ro4003 daim hlau.Rau kev teeb tsa ntawm epoxy / ci iav ua ib feem ntawm cov txheej txheem ib txwm ua, peb pom zoo ua noj ntawm 300 ° F, 250 ° f (121 ° c-149 ° C) rau 1 mus rau 2 teev.Ro4003C tsis muaj nplaim hluav taws.Nws tuaj yeem nkag siab tias lub phaj ntim rau hauv ib qho infrared (IR) chav tsev lossis kev ua haujlwm ntawm qhov kev sib kis ceev heev tuaj yeem ncav cuag qhov kub ntawm ntau tshaj 700 ° f (371 ° C);Ro4003C tuaj yeem pib combustion ntawm cov kub kub 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.
High-frequency laminates tuaj yeem khaws cia tsis tu ncua ntawm chav tsev kub (55-85 ° F, 13-30 ° C), av noo.Nyob rau hauv chav tsev kub, cov ntaub ntawv dielectric yog inert ntawm high humidity.Txawm li cas los xij, hlau txheej xws li tooj liab tuaj yeem oxidize thaum raug cov av noo siab.Cov txheej txheem ua ntej ntxuav ntawm PCBS tuaj yeem yooj yim tshem tawm corrosion los ntawm cov ntaub ntawv khaws cia zoo.
Cov khoom siv RO4003C tuaj yeem ua tshuab siv cov cuab yeej siv feem ntau siv rau epoxy / iav thiab tawv hlau.Cov ntawv ci tooj liab yuav tsum tau muab tshem tawm los ntawm cov lus qhia channel kom tsis txhob smearing.
