I-Rogers Microwave RF Automotive Radar PCB
I-PCB evame kakhulu ye-Millimeter Wave Automotive Radar
I-5G kanye nokuhamba ngeselula kuyimikhiqizo yokuhlanganiswa okujulile kwemboni yezimoto nobuchwepheshe bolwazi besizukulwane esisha njengokuxhumana, ubuhlakani bokwenziwa kanye nokubala okuphezulu kwama-IoT. Yiziqondiso eziyinhloko zentuthuko ehlakaniphile nenethiwekhi yezinkambu zomhlaba wonke zezimoto nezokuthutha. Imoto ezimele ehlonyiswe ngobuchwepheshe be-5G ingafinyelela ukushayela okuphephile kanye nokuhlangenwe nakho kokugibela okunethezekile. Ukudluliswa kwesignali ye-5G okusheshayo kuzonikeza uhlelo lwemoto isikhathi esengeziwe sokunikeza impendulo kanye nokucubungula, ngaleyo ndlela kuqinisekiswe ukuphepha kokushayela futhi kunikeze ulwazi lokushayela olusebenza kahle.
Ukusetshenziswa okuyinhloko ekushayeleni okuzenzakalelayo izinzwa ze-radar zamagagasi e-millimeter, ezisebenzisa kakhulu izinto ezifana ne-RO3003G2TM, RO3003TM, RO4830TM, CLTE-MWTM, njll. Zisetshenziswa kabanzi ku-radar yamagagasi e-millimeter angu-77GHz futhi zine-dielectric constant eqinile kakhulu kanye ne-ultra-low dissipation factor (i-dissipation factor engu-0.001 ivame ukuhlolwa ku-10 GHz). Ngesikhathi esifanayo, isakhiwo esingenayo i-glass fiber sinciphisa kakhulu ukuhlukahluka kwe-dielectric constant yendawo kubhendi yamagagasi e-millimeter, Ukususa umphumela we-fiberglass wesignali kukhulisa kakhulu ukuzinza kwesigaba senzwa ye-radar.
Ngokuthuthukiswa kwezinzwa ze-radar kubhendi yemvamisa engu-79 GHz (77-81 GHz), ububanzi be-bandwidth yazo yesiginali bungathuthukisa kakhulu ukuxazululwa kwezinzwa ze-radar, kwandise ama-engeli okuskena, futhi kufezwe ngisho nokuthwebula izithombe ze-4D.
I-Rogers PCB yenzwa ye-radar yamagagasi e-millimeter (bheka isithombe 1 no-2 ukuthola imininingwane)
Ithebula lepharamitha yokucaciswa kwe-(Rogers)RO3003™ I-PCB enemvamisa ephezulu
(Rogers) I-RO3003™ Ama-substrate e-frequency ephezulu ayizinto ezihlanganisiwe ze-PTFE ezigcwele izinto zobumba, ezisetshenziselwa ama-PCB kuma-microwave ebhizinisi kanye nezinhlelo ze-RF. Umklamo oyingqayizivele unikeza izinto ukuqina futhi uqeda ushintsho lwesinyathelo ku-dielectric constant yezinto ze-PTFE ezisetshenziswayo ezijwayelekile ekushiseni kwegumbi.
Ama-substrate e-Rogers RO3003™ ane-dielectric constants ezinzile (Dk: 0.00+/-0.04) kanye ne-dissipation factor (Df: 0.0010 ku-10GHz) emazingeni okushisa ahlukene kanye nama-frequency. Afaneleka kakhulu kuzinhlelo zokusebenza ezifana ne-automotive millimeter wave radar (77 GHz), izinhlelo zokusiza ukushayela ezithuthukisiwe (ADAS) kanye nengqalasizinda engenantambo ye-5G (i-millimeter wave).
I-substrate ye-RO3003™ inokuqina okuhle kakhulu kwemishini, okwenza kube lula ngabaklami ukusebenzisa izinto ezinezingqimba ezihlukene ze-dielectric kusekethe enezingqimba eyodwa lapho beklama amasekethe anezingqimba eziningi ngaphandle kwezinkinga zokugoba noma zokuthembeka. I-coefficient yokwandisa ukushisa ye-substrate ye-RO3003™ kusiqondiso se-X/Y ingu-17/16 (ppm/℃). Leli nani lilingana ne-coefficient yokukhulisa ukushisa yethusi, ngakho-ke inani elijwayelekile lokuncibilika kwe-etching (ukubhaka ngemva kokusika) kwezinto lingaphansi kuka-0.5mils/intshi, okubonisa ukuzinza okuhle kakhulu kobukhulu. I-CTE kusiqondiso se-Z ingu-25 (ppm/℃), futhi ngisho nasezindaweni zokushisa ezinzima, le nto isengaqinisekisa ukuzinza kwe-electroplated ngokusebenzisa izimbobo.
Umfanekiso 1: Ukwehluka okuncike ekushiseni kwe-dielectric constant ye-RO3003 kanye ne-RO3035 laminates
Njengoba kuboniswe esithombeni esingenhla, ama-dielectric constant e-RO3003 kanye ne-RO3035 laminates abonisa ukuzinza okuhle ngokushisa. Akukho ushintsho lwesinyathelo kuma-dielectric constant ekushiseni kwegumbi njenge-PTFE glass fiber.
Umfanekiso 2: Isici sokusaphazeka kwe-RO3003 kanye ne-RO3035.
Isithombe esingenhla sibonisa ukusatshalaliswa kwezinto zokusaphazeka kuma-laminate e-RO3003 kanye ne-RO3035. Indlela yokuhlola ye-RO3003-RO3035: IPC-TM-65025.5.5 Izimo zokuhlola: 10 GHz 23 °C.
Isicelo
Ukusetshenziswa kwe-substrate enemvamisa ephezulu (bheka isithombe 3-1 ukuthola imininingwane)
Imikhiqizo evamile yezingxenye ezisetshenziswa kakhulu: i-ARLON i-substrate enemvamisa ephezulu, i-TACONIC i-substrate enemvamisa ephezulu, i-ROGERS i-substrate enemvamisa ephezulu, i-Shengyi, i-Taiguang, i-Taiyao, i-Fushide, i-Wangling kanye neminye imikhiqizo eminingi.
