Kodi magulu a board a Rogers PCB ndi ati?

Zinthu za Rogers RO4350B zimalola mainjiniya a RF PCB kupanga mabwalo mosavuta, monga mafananidwe a netiweki ndi kuwongolera kwa mizere yopatsira.Chifukwa cha kuchepa kwa dielectric kutayika, zinthu za RO4350B zili ndi mwayi wosayerekezeka kuposa zida wamba zamagawo pamagwiritsidwe apamwamba kwambiri.Kusiyanasiyana kwa chilolezo ndi kutentha kumakhala kotsika kwambiri pakati pa zipangizo zofanana, ndipo chilolezo chake chimakhalanso chokhazikika pamafupipafupi, ndi malingaliro apangidwe a 3.66.Chojambula chamkuwa cha LoPra ™ chimachepetsa kutayika.Izi zimapangitsa kuti zinthuzo zikhale zoyenera kugwiritsa ntchito ma Broadband.

Rogers PCB board: zakuthupi ceramic mkulu pafupipafupi PCB mndandanda gulu:

RO3000 mndandanda: PTFE zozungulira zotengera kudzazidwa kwa ceramic, zitsanzo ndi: RO3003, RO3006, RO3010, RO3035 laminate yapamwamba kwambiri.

RT6000 mndandanda: zochokera ceramic wodzazidwa PTFE dera zipangizo, opangira mabwalo amagetsi ndi mayikirowevu mabwalo amafuna chilolezo mkulu.Zitsanzo ndi: RT6006 chilolezo 6.15, RT6010 chilolezo 10.2.

TMM mndandanda: zipangizo gulu zochokera ceramic, hydrocarbon, thermosetting polima, chitsanzo: TMM3, TMM4, TMM6, TMM10, TMM10i, TMM13i., ndi zina.
Zinthu za RO4003 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 borehole 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.

Zofunika kuphika za RO4000 ndizofanana ndi za epoxy/galasi.Nthawi zambiri, zida zomwe siziphika mbale za epoxy/magalasi sizifunika kuphika RO4003 PCBs.Kwa epoxy / yophika magalasi oyika ngati gawo la nthawi zonse, timalimbikitsa kuphika pa 300 ° F, 250 ° F (121 ° C-149 ° C) kwa maola 1 mpaka 2.RO4003 ilibe zoletsa moto.M'pake kuti mbale zoikidwa mu infuraredi (IR) mayunitsi kapena zogwira ntchito pa liwiro lotsika kwambiri lotumizira zimatha kufika kutentha kopitilira 700°F (371 °C);RO4003 ikhoza kuyamba kuyaka pa kutentha kwakukulu kumeneku.Makina omwe amagwiritsabe ntchito zida za infrared reflux kapena zida zina zomwe zimatha kufikira kutentha kwakukuluzi ziyenera kusamala kuti zitsimikizire kuti palibe ngozi.

Ro3003 ndi Rogers PCB board material ceramic yodzazidwa ndi PTFE composite for commercial microwave ndi RF application.Zogulitsa izi zimapangidwira kuti zipereke kukhazikika kwapamwamba kwamagetsi ndi makina pamtengo wopikisana.Rogers Ro3003 ili ndi kukhazikika kwachilolezo pamtundu wonse wa kutentha, kuphatikizapo kuthetsa kusintha kwa chilolezo komwe kumachitika pamene zipangizo zamagalasi za PTFE zimagwiritsidwa ntchito kutentha.Kuphatikiza apo, Ro3003 laminates ali ndi ma coefficients otayika otsika ngati 0.0013 mpaka 10 GHz.
