Rogers Microwave RF Automotive Radar PCB
PCB yothamanga kwambiri ya Millimeter Wave Automotive Radar
5G ndi kuyenda kwa mafoni ndizinthu zakuphatikizana kwakukulu kwamakampani amagalimoto okhala ndi matekinoloje azidziwitso am'badwo watsopano monga kulumikizana, luntha lochita kupanga komanso kugwiritsa ntchito kwambiri makompyuta a ma IoT. Ndiwo mayendedwe ofunikira pakukula kwanzeru komanso kolumikizidwa pamayendedwe apadziko lonse lapansi magalimoto ndi zoyendera. Galimoto yodziyimira yokha yokhala ndi ukadaulo wa 5G imatha kuyendetsa bwino komanso kukwera bwino. Kutumiza mwachangu kwa ma siginecha a 5G kudzapatsa makina agalimoto nthawi yochulukirapo kuti apereke mayankho ndi kukonza, potero kuwonetsetsa kuti magalimoto ali otetezeka komanso kuti azitha kuyendetsa bwino kwambiri.
Ntchito yaikulu pakuyendetsa galimoto ndi ma millimeter wave radar sensors, omwe amagwiritsa ntchito kwambiri zinthu monga RO3003G2TM, RO3003TM, RO4830TM, CLTE-MWTM, ndi zina zotero. Amagwiritsidwa ntchito kwambiri pa 77GHz millimeter wave radar ndipo amakhala ndi dielectric yokhazikika komanso yotsika kwambiri. factor (a dissipation factor of 0.001 nthawi zambiri amayesedwa pa 10 GHz). Nthawi yomweyo, kapangidwe kake kopanda magalasi opangira magalasi kumachepetsanso kusinthasintha kwa dielectric m'deralo mu millimeter wave frequency band, Kuchotsa mawonekedwe amtundu wa fiberglass kumawonjezera kukhazikika kwa gawo la sensor ya radar.
Ndi chitukuko cha masensa a radar mu 79 GHz frequency band (77-81 GHz), bandwidth yawo yokulirapo imatha kupititsa patsogolo kusinthika kwa masensa a radar, kukulitsa ma ngodya, komanso kukwanitsa kujambula kwa 4D.
Rogers PCB ya millimeter wave radar sensor (onani chithunzi 1 ndi 2 kuti mumve zambiri)
Specification parameter table ya (Rogers)RO3003™ High-frequency PCB
(Rogers) RO3003™ Magawo apamwamba kwambiri ndi zida za PTFE zodzazidwa ndi zoumba, zomwe zimagwiritsidwa ntchito pa PCB muzamalonda za microwave ndi ntchito za RF. Kapangidwe kapadera kamapangitsa kuti zinthuzo zikhale zokhazikika ndipo zimathetsa kusintha kwa dielectric kosasintha kwa zida za PTFE zomwe zimagwiritsidwa ntchito nthawi zonse kutentha.
Magawo a Rogers RO3003™ High frequency substrates 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. Zoyenera kwambiri kumapulogalamu monga automotive millimeter wave radar (77 GHz), advanced drive assist systems (ADAS) ndi 5G wireless infrastructure (millimeter wave).
Gawo laling'ono la RO3003 ™ lili ndi kukhazikika kwamakina, zomwe zimapangitsa kuti zikhale zosavuta kwa opanga kugwiritsa ntchito zida zokhala ndi ma dielectric mosiyanasiyana pagawo lagawo limodzi popanga mabwalo osanjikiza ambiri popanda zovuta kapena zodalirika. Kukula kwamafuta a gawo lapansi la RO3003™ ku mbali ya X/Y ndi 17/16 (ppm/℃). Mtengowu ndi wofanana ndi kuchuluka kwa matenthedwe amkuwa, kotero kuti mtengo wa etching shrinkage (kuphika pambuyo pa kukokera) wa zinthuzo ndi zosakwana 0.5mils/inchi, kusonyeza kukhazikika kwa dimensional. The CTE mu Z malangizo ndi 25 (ppm/℃), ndipo ngakhale m'madera otentha kutentha, zinthu zimenezi akadali kuonetsetsa bata electroplated kudzera mabowo.
Chithunzi 1: Kutentha kumadalira kusiyana kwa dielectric constant RO3003 ndi RO3035 laminates
Monga momwe tawonetsera pamwambapa, ma dielectric constants a RO3003 ndi RO3035 laminates amasonyeza kukhazikika kwabwino ndi kutentha. Palibe kusintha kwa ma dielectric pafupipafupi kutentha kwa firiji ngati PTFE galasi fiber.
Chithunzi 2: Zowonongeka za RO3003 ndi RO3035.
Chithunzi pamwambapa chikuwonetsa kugawidwa kwa zinthu zowonongeka mu RO3003 ndi RO3035 laminates. RO3003-RO3035 Njira yoyesera: IPC-TM-65025.5.5 Zoyeserera: 10 GHz 23 °C.
Kugwiritsa ntchito
Kugwiritsa ntchito gawo laling'ono la High-frequency (onani chithunzi 3-1 kuti mumve zambiri)
Mitundu yodziwika bwino yamagawo apamwamba kwambiri: gawo laling'ono la ARLON lalitali, gawo laling'ono la TACONIC, gawo laling'ono la ROGERS, Shengyi, Taiguang, Taiyao, Fushide, Wangling ndi mitundu ina yambiri. Katundu wamakampani: Rogers, Taconic, F4B, TP-2, FR-4 ndi magawo ena othamanga kwambiri, amafulumizitsa sampuli mkati mwa maola 24.
Rogers, monga mtsogoleri wotsogola padziko lonse lapansi wamagawo apadera, ali ndi gawo la msika wopitilira 50% padziko lonse lapansi komanso zaka 20 zazaka zambiri zamakampani pantchito ya base station antenna RF.
Rogers high-frequency materials amapangidwa ndi 3000 series, 4000 series, 5000 series, etc.
RICHPCBA imagwira ntchito popanga ma 2-68 layer microwave RF PCB ndi zinthu zina, zokhala ndi zida za Rogers zopezeka mosavuta, zotumizidwa kunja mumapaketi ake oyambira okhala ndi mitundu ingapo. Timapereka zitsanzo za ma Rogers apamwamba kwambiri a PCB, kupanga ndi kukonza ntchito.
Magawo ogwiritsira ntchito ma PCB othamanga kwambiri: amagwiritsidwa ntchito kwambiri pazida zoyankhulirana, kuwongolera mafakitale, nyumba zanzeru, zida zamagetsi makonda, makina azachipatala ndi magawo ena.
Radar yamagalimoto; GPS mlongoti; Njira yolumikizirana yam'manja : amplifier mphamvu ndi mlongoti; Wokwera mlongoti kulankhulana opanda zingwe; Satellite kufala mwachindunji; Chingwe dongosolo lolumikiza deta; owerenga mita akutali ndi backboard mphamvu, etc;
