I-Rogers Microwave RF Automotive Radar PCB
I-PCB ephindaphindayo ephezulu ye-Millimeter Wave Automotive Radar
I-5G kunye nokuhamba ngeselula ziimveliso zokudibanisa okunzulu kweshishini leemoto kunye neetekhnoloji zolwazi zesizukulwana esitsha ezifana nonxibelelwano, ubukrelekrele bokwenziwa kunye nekhompyutha esebenza kakuhle ye-IoTs. Ziindlela eziphambili zophuhliso olukrelekrele noludibeneyo lweenkalo zehlabathi zeemoto nezothutho. Isithuthi esizimeleyo esixhotyiswe ngetekhnoloji ye-5G sinokufezekisa ukuqhuba okukhuselekileyo kunye namava okukhwela akhululekileyo. Ukuhanjiswa kwesignali ye-5G ngokukhawuleza kuya kunika inkqubo yesithuthi ixesha elingakumbi lokubonelela ngempendulo kunye nokucubungula, ngaloo ndlela kuqinisekisa ukhuseleko lokuqhuba kunye nokubonelela ngamava okuqhuba asebenzayo ngakumbi.
Eyona nto iphambili ekuqhubeni ngokuzimela zii-millimeter wave radar sensors, ezisebenzisa kakhulu izixhobo ezifana ne-RO3003G2TM, RO3003TM, RO4830TM, CLTE-MWTM, njl. Zisetyenziswa kakhulu kwi-77GHz millimeter wave radar kwaye zine-dielectric constant ezinzileyo kakhulu kunye ne-ultra-low dissipation factor (i-dissipation factor ye-0.001 idla ngokuvavanywa kwi-10 GHz). Kwangaxeshanye, isakhiwo esingena-glass fiber sinciphisa ngakumbi umahluko we-dielectric constant yendawo kwi-millimeter wave frequency band, Ukususa isiphumo se-fiberglass sesignal kwandisa ngakumbi uzinzo lwesigaba se-radar sensor.
Ngophuhliso lwee-sensors ze-radar kwi-79 GHz frequency band (77-81 GHz), i-bandwidth yazo ebanzi yesignali inokuphucula ngakumbi isisombululo see-sensors ze-radar, yonyuse ii-angles zokuskena, kwaye ifikelele kwi-4D imaging.

Itheyibhile yeeparameter zeenkcukacha ze (Rogers)RO3003™ PCB ephindaphindayo
(Rogers) RO3003™ Ii-substrates ezisebenzisa i-PTFE ezigcwele iiseramikhi, ezisetyenziselwa ii-PCB kwi-microwave yorhwebo kunye nezicelo ze-RF. Uyilo olulodwa lunika izinto uzinzo kwaye lususa utshintsho lwenyathelo kwi-dielectric constant yezixhobo ze-PTFE ezisetyenziswa ngokubanzi kubushushu begumbi.
Ii-substrates zeRogers RO3003™ ezisebenzisa i-frequency ephezulu zisenazo ii-dielectric constants ezizinzileyo (Dk: 0.00+/-0.04) kunye ne-dissipation factor (Df: 0.0010 kwi-10GHz) kumaqondo obushushu ahlukeneyo kunye nee-frequency. Zifanelekile kakhulu kwizicelo ezifana ne-automotive millimeter wave radar (77 GHz), iinkqubo zoncedo lokuqhuba eziphambili (ADAS) kunye ne-5G wireless infrastructure (millimeter wave).
I-substrate ye-RO3003™ inozinzo oluhle kakhulu loomatshini, nto leyo eyenza kube lula kubayili ukusebenzisa izixhobo ezinee-dielectric constants ezahlukeneyo kwisekethe yomaleko omnye xa beyila iisekethe zomaleko omninzi ngaphandle kweengxaki zokugoba okanye zokuthembeka. I-coefficient yokwandiswa kobushushu ye-RO3003™ substrate kwicala le-X/Y yi-17/16 (ppm/℃). Eli xabiso lilingana ne-coefficient yokwandiswa kobushushu yobhedu, ngoko ke ixabiso eliqhelekileyo lokuncitshiswa kwe-etching (ukubhaka emva kokugcada) kwezinto lingaphantsi kwe-0.5mils/intshi, nto leyo ebonisa uzinzo oluhle kakhulu. I-CTE kwicala le-Z yi-25 (ppm/℃), kwaye nakwiindawo zobushushu ezinzima, ezi zinto zisenokuqinisekisa uzinzo lwe-electroplated ngokusebenzisa imingxunya.
Umfanekiso 1: Utshintsho oluxhomekeke kubushushu lwe-dielectric constant ye-RO3003 kunye ne-RO3035 laminates
Njengoko kubonisiwe kumfanekiso ongentla, ii-dielectric constants ze-RO3003 kunye ne-RO3035 laminates zibonisa uzinzo oluhle kunye nobushushu. Akukho tshintsho lwenyathelo kwi-dielectric constant kubushushu begumbi njenge-PTFE glass fiber.
Umfanekiso 2: Into yokusasaza i-RO3003 kunye ne-RO3035.
Lo mfanekiso ungentla ubonisa ukusasazwa kwezinto ezisasazwayo kwi-RO3003 kunye ne-RO3035 laminates. Indlela yovavanyo lwe-RO3003-RO3035: IPC-TM-65025.5.5 Iimeko zovavanyo: 10 GHz 23 °C.
