5G le maeto a mehala ke lihlahisoa tsa kopanyo e tebileng ea indasteri ea likoloi le mahlale a morao-rao a tlhahiso-leseling a kang puisano, bohlale ba maiketsetso le khomphutha ea ts'ebetso e phahameng ea li-IoT. Ke litataiso tsa mantlha bakeng sa nts'etsopele e bohlale le ea marang-rang ea libaka tsa lefatše tsa likoloi le lipalangoang. Koloi e ikemetseng e nang le theknoloji ea 5G e ka fumana ho khanna ho bolokehileng le boiphihlelo bo botle ba ho palama. Phatlalatso ea lets'oao la 5G e potlakileng e tla fa sistimi ea koloi nako e eketsehileng ea ho fana ka maikutlo le ts'ebetso, ka hona e netefatsa polokeho ea ho khanna le ho fana ka boiphihlelo bo nepahetseng ba ho khanna.
Kopo e ka sehloohong ea ho khanna ka boipuso ke li-millimeter wave radar sensors, tseo haholo-holo li sebelisang lisebelisoa tse kang RO3003G2TM, RO3003TM, RO4830TM, CLTE-MWTM, joalo-joalo Li sebelisoa haholo ho 77GHz millimeter wave radar 'me li na le dielectric tse tsitsitseng kamehla le ultra-low dissipation. factor (a dissipation factor of 0.001 hangata e lekoa ho 10 GHz). Ka nako e ts'oanang, sebopeho se se nang fiber ea khalase se fokotsa ho fapana ha dielectric kamehla sebakeng sa millimeter wave frequency band, Ho felisa phello ea fiberglass ea lets'oao ho eketsa botsitso ba karolo ea sensor ea radar.
Ka nts'etsopele ea li-sensor tsa radar ho 79 GHz frequency band (77-81 GHz), bandwidth ea bona e pharalletseng e ka ntlafatsa le ho feta tharollo ea li-radar sensors, ho eketsa li-angles tsa scanning, esita le ho fihlela litšoantšo tsa 4D.

Specification parameter table ea (Rogers)RO3003™ High-frequency PCB
(Rogers) RO3003™ Li-substrates tse phahameng tsa maqhubu ke lisebelisoa tse kopaneng tsa PTFE tse tlatsitsoeng ka lirafshoa, tse sebelisetsoang li-PCB lits'ebetsong tsa microwave le tsa RF. Moqapi o ikhethang o etsa hore thepa e be le botsitso 'me e felise phetoho ea mehato ea dielectric kamehla ea lisebelisoa tsa PTFE ka kakaretso mocheso oa kamore.
Rogers RO3003™ Li-substrates tse phahameng tsa maqhubu li ntse li e-na le lisebelisoa tse tsitsitseng tsa dielectric (Dk: 0.00 +/-0.04) le dissipation factor (Df: 0.0010 ho 10GHz) ka mocheso o fapaneng le maqhubu. E loketse haholo lits'ebetsong tse joalo ka radar ea koloi millimeter wave (77 GHz), sistimi e tsoetseng pele ea lithuso tsa ho khanna (ADAS) le 5G wireless infrastructure (millimeter wave).
RO3003 ™ substrate e na le botsitso bo botle ba mochini, e etsa hore ho be bonolo ho baqapi ho sebelisa lisebelisoa tse nang le li-contants tse fapaneng tsa dielectric potolohong ea lera le le leng ha ba rala lipotoloho tse nang le mekhahlelo e mengata ntle le mathata a ntoa kapa a ts'epahalo. Coefficient ea katoloso ea mocheso ea RO3003™ substrate ka lehlakoreng la X/Y ke 17/16 (ppm/℃). Boleng bona bo lekana le coefficient ea katoloso ea mocheso ea koporo, kahoo boleng bo tloaelehileng ba ho nyenyefala ha etching (ho baka ka mor'a etching) ea thepa e ka tlase ho 0.5mils/inch, ho bonts'a botsitso bo botle ba sebopeho. The CTE ka Z tataiso ke 25 (ppm/℃), esita le libakeng tse thata mocheso, thepa ena ntse ka etsa bonnete ba botsitso ba electroplated ka masoba.
