Tom ntej: Rogers Microwave RF Automotive Radar PCB
High-frequency PCB rau millimeter Wave Automotive Radar
5G thiab mobile mus ncig yog cov khoom lag luam ntawm kev sib sib zog nqus ntawm kev lag luam tsheb nrog cov ntaub ntawv tshiab tiam tshiab xws li kev sib txuas lus, kev txawj ntse txawj ntse thiab kev ua haujlwm siab ntawm IoTs. Lawv yog cov lus qhia tseem ceeb rau kev txawj ntse thiab kev sib txuas ntawm kev tsim kho tsheb thoob ntiaj teb thiab kev thauj mus los. Lub tsheb autonomous nruab nrog 5G thev naus laus zis tuaj yeem ua tiav kev tsav tsheb nyab xeeb thiab kev caij tsheb zoo dua. Kev xa tawm sai dua 5G teeb liab yuav muab sijhawm rau lub tsheb ntau dua los muab kev tawm tswv yim thiab ua tiav, yog li ua kom muaj kev nyab xeeb ntawm kev tsav tsheb thiab muab kev tsav tsheb zoo dua.
Cov ntawv thov tseem ceeb hauv kev tsav tsheb tsis muaj zog yog millimeter yoj radar sensors, uas feem ntau siv cov ntaub ntawv xws li RO3003G2TM, RO3003TM, RO4830TM, CLTE-MWTM, thiab lwm yam. yam (qhov cuam tshuam ntawm 0.001 feem ntau kuaj ntawm 10 GHz). Nyob rau tib lub sijhawm, cov qauv tsis muaj iav fiber ntau ntxiv txo qhov kev hloov pauv ntawm lub zos dielectric tas li nyob rau hauv millimeter yoj zaus band, tshem tawm cov nyhuv fiberglass ntawm lub teeb liab ntxiv ua rau cov theem stability ntawm lub radar sensor.
Nrog rau kev txhim kho ntawm radar sensors hauv 79 GHz zaus band (77-81 GHz), lawv cov teeb liab dav dav tuaj yeem txhim kho qhov kev daws teeb meem ntawm radar sensors, nce lub kaum ntse ntse scan, thiab txawm tias ua tiav 4D duab.

Specification parameter rooj ntawm (Rogers) RO3003 ™ High-frequency PCB
(Rogers) RO3003 ™ High zaus substrates yog PTFE cov ntaub ntawv sib xyaw uas muaj cov ceramics, siv rau PCBs hauv kev lag luam microwave thiab RF daim ntaub ntawv. Tus tsim tshwj xeeb endows cov khoom nrog kev ruaj ntseg thiab tshem tawm cov kauj ruam hloov hauv dielectric tas li ntawm cov khoom siv PTFE dav dav ntawm chav tsev kub.
Rogers RO3003™ High zaus substrates tseem muaj cov dielectric ruaj khov (Dk: 0.00+/-0.04) thiab dissipation factor (Df: 0.0010 ntawm 10GHz) ntawm qhov sib txawv ntawm qhov kub thiab ntau zaus. Zoo heev rau kev siv xws li tsheb millimeter yoj radar (77 GHz), kev tsav tsheb siab tshaj (ADAS) thiab 5G wireless infrastructure (millimeter yoj).
RO3003 ™ substrate muaj kev ruaj ntseg zoo heev, ua rau nws yooj yim rau cov neeg tsim khoom siv cov khoom sib txawv dielectric tsis tu ncua hauv ib txheej txheej txheej thaum tsim cov txheej txheem ntau yam tsis muaj teeb meem los yog kev ntseeg siab. Lub thermal expansion coefficient ntawm RO3003 ™ substrate nyob rau hauv X / Y kev taw qhia yog 17/16 (ppm / ℃). Tus nqi no yog sib npaug rau cov thermal expansion coefficient ntawm tooj liab, yog li tus nqi raug ntawm etching shrinkage (ci tom qab etching) ntawm cov khoom yog tsawg dua 0.5mils / nti, ua kom pom kev ruaj ntseg zoo heev. CTE nyob rau hauv Z kev taw qhia yog 25 (ppm / ℃), thiab txawm nyob rau hauv hnyav kub ib puag ncig, cov khoom no tseem tuaj yeem ua kom ruaj khov ntawm electroplated los ntawm qhov.
Daim duab 1: Qhov kub thiab txias hloov pauv ntawm dielectric tas li ntawm RO3003 thiab RO3035 laminates
Raws li pom nyob rau hauv daim duab saum toj no, lub dielectric qhov tsis tu ncua ntawm RO3003 thiab RO3035 laminates pom zoo stability nrog kub. Tsis muaj kev hloov pauv hauv dielectric tas li ntawm chav tsev kub zoo li PTFE iav fiber ntau.
Daim duab 2: Dissipation factor ntawm RO3003 thiab RO3035.
Daim duab saum toj no qhia txog kev faib tawm ntawm cov txheej txheem dissipation hauv RO3003 thiab RO3035 laminates. RO3003-RO3035 Test method: IPC-TM-65025.5.5 Test tej yam kev mob: 10 GHz 23 ° C.
