Rogers Microwave RF Automotive Radar PCB
PCB yapamwamba kwambiri ya Millimeter Wave Automotive Radar
5G ndi maulendo apafoni ndi zinthu zomwe zimapangitsa kuti makampani opanga magalimoto azigwirizana kwambiri ndi ukadaulo watsopano monga kulankhulana, luntha lochita kupanga komanso kugwiritsa ntchito makompyuta apamwamba a IoT. Ndiwo malangizo akuluakulu opititsa patsogolo chitukuko cha magalimoto padziko lonse lapansi komanso mayendedwe. Galimoto yodziyimira yokha yokhala ndi ukadaulo wa 5G imatha kuyendetsa bwino komanso kukhala ndi luso loyendetsa bwino. Kutumiza mwachangu kwa chizindikiro cha 5G kudzapatsa makina agalimoto nthawi yochulukirapo yopereka mayankho ndi kukonza, potero kuonetsetsa kuti kuyendetsa bwino komanso kupereka chidziwitso choyendetsa bwino.
Ntchito yaikulu pakuyendetsa yokha ndi masensa a radar a millimeter wave, omwe amagwiritsa ntchito kwambiri zinthu monga RO3003G2TM, RO3003TM, RO4830TM, CLTE-MWTM, ndi zina zotero. Amagwiritsidwa ntchito kwambiri mu 77GHz millimeter wave radar ndipo ali ndi dielectric constant yokhazikika komanso ultra-low dissipation factor (dissipation factor ya 0.001 nthawi zambiri imayesedwa pa 10 GHz). Nthawi yomweyo, kapangidwe kopanda ulusi wagalasi kamachepetsanso kusinthasintha kwa dielectric constant yapafupi mu millimeter wave frequency band, Kuchotsa mphamvu ya fiberglass ya chizindikiro kumawonjezeranso kukhazikika kwa gawo la sensa ya radar.
Ndi chitukuko cha masensa a radar mu gulu la ma frequency la 79 GHz (77-81 GHz), bandwidth yawo yayikulu ya chizindikiro imatha kupititsa patsogolo kulondola kwa masensa a radar, kuonjezera ma scanning angles, komanso kukwaniritsa kujambula kwa 4D.
Rogers PCB ya sensa ya radar ya mafunde a millimeter (onani chithunzi 1 ndi 2 kuti mudziwe zambiri)
Tebulo la magawo ofotokozera a (Rogers)RO3003™ PCB yapamwamba kwambiri
(Rogers) RO3003™ Ma substrates okhala ndi ma frequency apamwamba ndi zinthu zopangidwa ndi PTFE zodzazidwa ndi zoumba, zomwe zimagwiritsidwa ntchito pa ma PCB mu ma microwave amalonda ndi ma RF. Kapangidwe kake kapadera kamapangitsa kuti zinthuzo zikhale zokhazikika ndipo kamachotsa kusintha kwa magawo a dielectric constant ya zinthu za PTFE zomwe zimagwiritsidwa ntchito nthawi zonse kutentha kwa chipinda.
Ma substrates a Rogers RO3003™ okhala ndi ma frequency apamwamba akadali ndi ma dielectric constants okhazikika (Dk: 0.00+/-0.04) ndi dissipation factor (Df: 0.0010 pa 10GHz) pa kutentha ndi ma frequency osiyanasiyana. Ndi oyenera kwambiri kugwiritsa ntchito monga automotive millimeter wave radar (77 GHz), advanced driving assistance systems (ADAS) ndi 5G wireless infrastructure (millimeter wave).
Chitsulo cha RO3003™ chili ndi kukhazikika kwabwino kwa makina, zomwe zimapangitsa kuti opanga zinthu azitha kugwiritsa ntchito zipangizo zokhala ndi ma dielectric constants osiyanasiyana mu dera limodzi popanga ma multi-layer circuit popanda mavuto opotoka kapena kudalirika. Kuchuluka kwa kutentha kwa RO3003™ substrate mu X/Y direction ndi 17/16 (ppm/℃). Mtengo uwu ndi wofanana ndi kuchuluka kwa kutentha kwa mkuwa, kotero mtengo wamba wa etching shrinkage (kuphika pambuyo etching) wa chinthucho ndi wochepera 0.5mils/inch, zomwe zikuwonetsa kukhazikika kwabwino kwambiri. CTE mu Z direction ndi 25 (ppm/℃), ndipo ngakhale m'malo otentha kwambiri, chinthuchi chingatsimikizirebe kukhazikika kwa electroplated kudzera m'mabowo.
Chithunzi 1: Kusintha kwa kutentha kwa dielectric constant ya RO3003 ndi RO3035 laminates kumadalira kutentha
Monga momwe chithunzi chili pamwambapa chikusonyezera, ma dielectric constants a RO3003 ndi RO3035 laminates amakhala okhazikika bwino ndi kutentha. Palibe kusintha kwa ma dielectric constant pa kutentha kwa chipinda monga PTFE glass fiber.
Chithunzi 2: Chida choyeretsera cha RO3003 ndi RO3035.
Chithunzi chomwe chili pamwambapa chikuwonetsa kufalikira kwa zinthu zotayira mu RO3003 ndi RO3035 laminates. Njira yoyesera ya RO3003-RO3035: IPC-TM-65025.5.5 Mikhalidwe yoyesera: 10 GHz 23 °C.
Kugwiritsa ntchito
Kugwiritsa ntchito gawo lokhala ndi ma frequency ambiri (onani chithunzi 3-1 kuti mudziwe zambiri)
Mitundu yodziwika bwino ya ma substrates okhala ndi ma frequency apamwamba: ARLON substrate yokhala ndi ma frequency apamwamba, TACONIC high-frequency substrate, ROGERS high-frequency substrate, Shengyi, Taiguang, Taiyao, Fushide, Wangling ndi mitundu ina yambiri. Kampaniyi ili ndi: Rogers, Taconic, F4B, TP-2, FR-4 ndi ma substrates ena okhala ndi ma frequency apamwamba, ndipo yathandiza kuti anthu azitha kunyamula zitsanzo mwachangu mkati mwa maola 24.
Rogers, monga kampani yotsogola padziko lonse lapansi yopereka zinthu zapadera, ali ndi gawo la msika loposa 50% padziko lonse lapansi komanso zaka 20 zaukadaulo pantchito yopangira ma antenna a RF pa siteshoni ya base.
Zipangizo za Rogers zapamwamba kwambiri zimapangidwa ndi mndandanda wa 3000, mndandanda wa 4000, mndandanda wa 5000, ndi zina zotero.
RICHPCBA imagwira ntchito popanga ma microwave RF PCB okhala ndi zigawo ziwiri mpaka makumi asanu ndi limodzi ndi zitatu (2-68 layer), ndipo zipangizo za Rogers zomwe zimapezeka mosavuta, zomwe zimatumizidwa m'mapaketi awo oyambirira ndi mitundu yonse ya mitundu. Timapereka ntchito zoyezera, kupanga ndi kukonza ma PCB a Rogers omwe amapezeka pafupipafupi.
Magawo ogwiritsira ntchito ma PCB apamwamba kwambiri: amagwiritsidwa ntchito kwambiri pazida zolumikizirana, zowongolera mafakitale, nyumba zanzeru, zida zamagetsi zosinthidwa, makina azachipatala ndi zina.
Radar yamagalimoto; Antena ya GPS; Dongosolo lolumikizirana la mafoni: amplifier yamagetsi ndi antena; Antena yoyikidwa yolumikizirana opanda zingwe; Satellite yotumizira mwachindunji; Dongosolo la chingwe lolumikizira deta; Wowerenga mita yakutali ndi bolodi lamagetsi, ndi zina zotero;
