Rogers Microwave RF Automotive Radar PCB
High-frequency PCB for Millimeter Wave Automotive Radar
I-5G kunye nokuhamba ngeselula ziyimveliso yokuhlanganiswa okunzulu kweshishini leemoto kunye nobuchwepheshe bolwazi lwesizukulwana esitsha njengonxibelelwano, i-intelligence yokwenziwa kunye ne-high-performance computing ye-IoTs. Zezona zalathiso ziphambili zophuhliso olukrelekrele kunye nothungelwano lwemimandla yeemoto kunye nezothutho zehlabathi. Isithuthi esizimeleyo esixhotyiswe ngetekhnoloji ye-5G sinokufikelela ekuqhubeni okukhuselekileyo kunye namava okukhwela akhululeke ngakumbi. Ukuhanjiswa komqondiso okhawulezayo we-5G kuya kunika inkqubo yesithuthi ixesha elingakumbi lokubonelela ngengxelo kunye nokusetyenzwa, ngaloo ndlela iqinisekisa ukhuseleko lokuqhuba kunye nokubonelela ngamava okuqhuba asebenzayo.
Esona sicelo siphambili kwi-autonomous drive yi-millimeter wave wave radar sensors, esetyenziswa ikakhulu izinto ezifana ne-RO3003G2TM, RO3003TM, RO4830TM, CLTE-MWTM, njl. Zisetyenziswa ngokubanzi kwi-77GHz millimeter wave radar kwaye zine-dielectric ezinzileyo kunye ne-ultra-low dissipation. factor (i-disipation factor ye-0.001 ivame ukuvavanywa kwi-10 GHz). Kwangaxeshanye, ulwakhiwo ngaphandle kwefiber yeglasi kunciphisa ngakumbi ukuguquguquka kwe-dielectric rhoqo kwi-millimeter wave frequency band, Ukuphelisa umphumo we-fiberglass wesignali kwandisa ukuzinza kwesigaba se-radar sensor.
Ngophuhliso lwe-radar sensors kwi-79 GHz frequency band (77-81 GHz), i-bandwidth yesignali ebanzi inokuphucula ngakumbi isisombululo se-radar sensors, ukwandisa i-engile yokuskena, kunye nokufezekisa i-imaging ye-4D.

Itheyibhile yokuchaza iparamitha ye (Rogers)RO3003™ Isantya esiphezulu sePCB
(Rogers) I-RO3003™ Ii-substrates zefrikhwensi eziphakamileyo zizimathiriyeli ezihlanganisiweyo ze-PTFE ezizaliswe ngeeseramikhi, ezisetyenziselwa ii-PCBs kurhwebo lwe-microwave kunye nosetyenziso lweRF. Uyilo olulodwa lunika izinto ngokuzinza kwaye luphelise utshintsho lwenyathelo kwi-dielectric constant ye-PTFE yenjongo jikelele yezixhobo kwiqondo lokushisa.
I-Rogers RO3003™ Ii-substrates eziphezulu ze-frequency zisenazo ii-dielectric constants ezizinzile (Dk: 0.00+/-0.04) kunye ne-dissipation factor (Df: 0.0010 kwi-10GHz) kumaqondo okushisa ahlukeneyo kunye nee-frequencies. Ifaneleke kakhulu kwizicelo ezifana ne-automotive millimeter wave radar (77 GHz), iinkqubo zokuncedisa ukuqhuba (ADAS) kunye ne-5G yeziseko ezingenazintambo (i-millimeter wave).
I-RO3003 ™ substrate inozinzo olugqwesileyo lomatshini, nto leyo eyenza kube lula ukuba abaqulunqi basebenzise imathiriyeli enee-dielectric constants ezahlukeneyo kwisekethe yomgangatho omnye xa kuyilwa iisekethe ezinomaleko amaninzi ngaphandle kokurhwaphiliza okanye ukuthembeka. I-coefficient yokwandiswa kwe-thermal ye-RO3003™ substrate kwicala le-X/Y yi-17/16 (ppm/℃). Eli xabiso lilingana ne-coefficient yokwandiswa kwe-thermal yobhedu, ngoko ke ixabiso eliqhelekileyo le-etching shrinkage (ukubhaka emva kokutshitshiswa) kwezinto ezingaphantsi kwe-0.5mils / intshi, ebonisa uzinzo olubalaseleyo lwe-dimensional. I-CTE kwicala le-Z yi-25 (ppm / ℃), kwaye nakwiindawo zokushisa ezinzima, le nto inokuqinisekisa ukuzinza kwe-electroplated ngokusebenzisa imingxuma.
Umzobo 1: Ukuhluka okuxhomekeke kwiqondo lokushisa kwe-dielectric constant ye-RO3003 kunye ne-RO3035 laminates
Njengoko kuboniswe kulo mfanekiso ungentla, i-dielectric constants ye-RO3003 kunye ne-RO3035 laminates ibonisa ukuzinza okulungileyo kunye nobushushu. Akukho nyathelo utshintsho kwi-dielectric engaguqukiyo kwiqondo lobushushu begumbi njenge-PTFE yeglasi yefiber.
Umzobo 2: I-Disipation factor ye-RO3003 kunye ne-RO3035.
Lo mzobo ungentla ubonisa ukusasazwa kwezinto ezichithwayo kwi-RO3003 kunye ne-RO3035 laminates. RO3003-RO3035 Indlela yokuvavanya: IPC-TM-65025.5.5 Iimeko zovavanyo: 10 GHz 23 °C.
