4 Layer ENIG RO4003+AD255 Mixed Lamination PCB
RO4003C Rogers High Frequency PCB Zida
Zinthu za RO4003C zitha kuchotsedwa ndi burashi wamba wa nayiloni.Palibe akuchitira wapadera chofunika pamaso electroplating mkuwa popanda magetsi.Mbaleyo iyenera kuthandizidwa pogwiritsa ntchito njira yachizolowezi ya epoxy / galasi.Nthawi zambiri, sikoyenera kuchotsa boreho chifukwa utomoni wapamwamba wa TG (280°C+[536°F]) susintha mtundu mosavuta pobowola.Ngati banga amayamba ndi aukali pobowola ntchito, utomoni akhoza kuchotsedwa ntchito muyezo CF4/O2 plasma mkombero kapena wapawiri alkaline permanganate ndondomeko.
Malo a RO4003C atha kukhala okonzedwa mwamakina komanso/kapena mwamankhwala kuti atetezeke kuwala.Ndibwino kugwiritsa ntchito photoresists wamadzimadzi kapena theka-amadzimadzi.Chopukuta chilichonse chamkuwa chogulitsidwa chingagwiritsidwe ntchito.Masks onse osefedwa kapena ogulidwa ndi zithunzi omwe amagwiritsidwa ntchito ngati ma epoxy/glass laminates amamatira bwino kwambiri pamwamba pa ro4003C.Kuyeretsa kwamakina pamalo owonekera a dielectric musanagwiritse ntchito masks owotchera ndi malo osankhidwa "olembetsedwa" kupewetsa kumamatira koyenera.
Zofunikira pakuphika kwa zida za ro4000 ndizofanana ndi epoxy/glass.Nthawi zambiri, zida zomwe siziphika mbale za epoxy / magalasi sizifunikira kuphika mbale za ro4003.Kuyika magalasi a epoxy / ophika ngati gawo la njira wamba, timalimbikitsa kuphika pa 300 ° F, 250 ° F (121 ° c-149 ° C) kwa maola 1 mpaka 2.Ro4003C ilibe choletsa moto.Zitha kumveka kuti mbale yopakidwa mu infrared (IR) unit kapena yogwira ntchito pa liwiro lotsika kwambiri imatha kufikira kutentha kopitilira 700 ° F (371 ° C);Ro4003C imatha kuyaka pamatenthedwe apamwambawa.Makina omwe amagwiritsabe ntchito zida za infrared reflux kapena zida zina zomwe zimatha kufikira kutentha kwakukuluzi ziyenera kusamala kuti zitsimikizire kuti palibe chowopsa.
Ma laminates okwera kwambiri amatha kusungidwa kosatha kutentha (55-85 ° F, 13-30 ° C), chinyezi.Pa kutentha kwa chipinda, zipangizo za dielectric zimakhala ndi chinyezi chambiri.Komabe, zokutira zachitsulo monga zamkuwa zimatha kutulutsa oxidize zikakhala ndi chinyezi chambiri.Standard chisanadze kuyeretsa PCBS mosavuta kuchotsa dzimbiri ku zinthu zosungidwa bwino.
Zinthu za RO4003C zimatha kupangidwa pogwiritsa ntchito zida zomwe zimagwiritsidwa ntchito popanga epoxy / galasi komanso zitsulo zolimba.Chojambula chamkuwa chiyenera kuchotsedwa mu njira yolondolera kuti asapakapakake.
