Rogers Microwave RF Mota Radar PCB
PCB yepamusoro-soro yeMillimeter Wave Automotive Radar
5G nekufamba nefoni zvibereko zvekubatanidzwa kwakadzama kweindasitiri yemotokari neruzivo rwechizvarwa chitsva rwakadai sekutaurirana, huchenjeri hwekugadzira uye kugona kwemakombiyuta eIoT. Ndiwo mafambiro makuru ekuvandudza kwakangwara uye kwakabatana kweminda yepasi rose yemotokari nekutakura. Mota inozvimiririra ine tekinoroji ye5G inogona kuwana kutyaira kwakachengeteka uye ruzivo rwakasununguka rwekutasva. Kutumira masaini e5G nekukurumidza kuchapa sisitimu yemotokari nguva yakawanda yekupa mhinduro nekugadzirisa, nokudaro ichivimbisa kuchengetedzeka kwekutyaira uye kupa ruzivo rwekutyaira rwunoshanda zviri nani.
Chinonyanya kushandiswa mukutyaira kwega i millimeter wave radar sensors, iyo inonyanya kushandisa zvinhu zvakaita seRO3003G2TM, RO3003TM, RO4830TM, CLTE-MWTM, nezvimwewo. Dzinoshandiswa zvakanyanya mu 77GHz millimeter wave radar uye dzine dielectric constant yakasimba uye ultra-low dissipation factor (dissipation factor ye 0.001 inowanzo edzwa pa 10 GHz). Panguva imwe chete, chimiro chisina girazi fiber chinoderedzawo kusiyana kwe local dielectric constant mu millimeter wave frequency band, Kubvisa fiberglass effect yesignal kunowedzerawo kugadzikana kwe phase ye radar sensor.
Nekugadzirwa kwemasensa eradar mu79 GHz frequency band (77-81 GHz), bandwidth yavo yakakura yesignali inogona kuwedzera kugadzirisa kwemasensa eradar, kuwedzera maangle ekuskena, uye kutoita kuti pave ne4D imaging.
Rogers PCB ye sensor ye radar ye millimeter wave (ona mufananidzo 1 ne2 kuti uwane rumwe ruzivo)
Tafura yemaparamita ekutsanangurwa e (Rogers)RO3003™ High-frequency PCB
(Rogers) RO3003™ Zvishandiso zve PTFE zvinogadzirwa ne ceramics, zvinoshandiswa paPCB muma microwave neRF applications. Dhizaini iyi yakasiyana inoita kuti zvinhu zvigadzikane uye inobvisa kuchinja kwe dielectric constant yezvinhu zve PTFE zvinoshandiswa pakupisa kwemumba.
Rogers RO3003™ High frequency substrates ichiri ne stable dielectric constants (Dk: 0.00+/-0.04) uye dissipation factor (Df: 0.0010 pa10GHz) patembiricha dzakasiyana uye ma frequency. Yakakodzera kwazvo kumashandisirwo akadai se automotive millimeter wave radar (77 GHz), advanced driving assistance systems (ADAS) uye 5G wireless infrastructure (millimeter wave).
Substrate yeRO3003™ ine kugadzikana kwakanaka kwazvo kwemuchina, zvichiita kuti zvive nyore kune vagadziri kushandisa zvinhu zvine ma dielectric constants akasiyana mudunhu re single-layer pavanenge vachigadzira ma multi-layer circuits pasina matambudziko ekukombama kana ekuvimbika. Kuwanda kwekuwedzera kwekupisa kwe RO3003™ substrate munzira ye X/Y i17/16 (ppm/℃). Kukosha uku kwakaenzana nekuwedzera kwekupisa kwe copper, saka kukosha kwakajairika kwekupwanya (kubika mushure mekucheka) kwezvinhu kuri pasi pe 0.5mils/inch, zvichiratidza kugadzikana kwakanaka kwazvo. CTE iri munzira ye Z i25 (ppm/℃), uye kunyangwe munzvimbo dzakaoma dzekupisa, zvinhu izvi zvinogona kuramba zvichivimbisa kugadzikana kwe electroplated kuburikidza nemaburi.
Mufananidzo 1: Kusiyana kwe dielectric constant yeRO3003 neRO3035 laminates kunoenderana nekupisa
Sezvakaratidzwa mumufananidzo uri pamusoro apa, ma "dielectric constant" e "RO3003" ne "RO3035 laminates" anoratidza kugadzikana kwakanaka nekupisa. Hapana shanduko ye "dielectric constant" pakupisa kwemumba senge "PTFE glass fiber".
Mufananidzo 2: Chinhu chinobvisa RO3003 neRO3035.
Mufananidzo uri pamusoro apa unoratidza kupararira kwezvinhu zvinoparadzira mu RO3003 ne RO3035 laminates. RO3003-RO3035 Nzira yekuyedza: IPC-TM-65025.5.5 Mamiriro ekuyedza: 10 GHz 23 °C.
Kushandiswa
Kushandisa substrate ine mafrequency akawanda (ona mufananidzo 3-1 kuti uwane rumwe ruzivo)
Mhando dzakajairika dzesubstrates dzine mafrequency akawanda: ARLON substrate ine mafrequency akawanda, TACONIC high-frequency substrate, ROGERS high-frequency substrate, Shengyi, Taiguang, Taiyao, Fushide, Wangling nedzimwe mhando dzakawanda. Kambani: Rogers, Taconic, F4B, TP-2, FR-4 nedzimwe substrates dzine mafrequency akawanda, dzakakurumidza kutora sampuli mukati memaawa makumi maviri nemana.
Rogers, semutengesi anotungamira pasi rose wezvinhu zvakakosha, ane mugove wemusika unopfuura 50% pasi rose uye ane makore makumi maviri eruzivo muindasitiri mumunda we antenna RF yechiteshi chepasi.
Zvinhu zveRogers zvine mafrequency akawanda zvinoumbwa ne3000 series, 4000 series, 5000 series, nezvimwewo.
RICHPCBA inonyanya kugadzira ma microwave RF PCB ane 2-68 layer nezvimwe zvigadzirwa, nezvinhu zveRogers zvine frequency yakakwira zviripo, zvinounzwa mumapakeji azvo ekutanga nemamodheru akasiyana-siyana. Tinopa masevhisi eRogers ekugadzira, kugadzira uye kugadzirisa ma PCB ane frequency yakakwira.
Minda yekushandisa maPCB ane maPCB akawanda: anoshandiswa zvakanyanya mumidziyo yekutaurirana, kudzora maindasitiri, dzimba dzakangwara, magetsi akagadzirwa, michina yekurapa nedzimwe nzvimbo.
Radar yemotokari; antenna yeGPS; Sisitimu yekutaurirana nefoni: amplifier yemagetsi neantenna; Antena yakaiswa yekutaurirana pasina waya; Satellite yekutumira zvakananga; Sisitimu yetambo yekubatanidza data; Muverengi wemita uri kure uye backboard yemagetsi, nezvimwewo;
