Rogers Microwave RF Automotive Radar PCB
PCB zaus siab rau Millimeter Wave Automotive Radar
5G thiab kev mus ncig ua si hauv xov tooj ntawm tes yog cov khoom lag luam ntawm kev sib koom ua ke tob ntawm kev lag luam tsheb nrog cov thev naus laus zis tshiab xws li kev sib txuas lus, kev txawj ntse ntawm lub cev thiab kev suav lej siab ntawm IoT. Lawv yog cov lus qhia tseem ceeb rau kev txhim kho ntse thiab kev sib txuas lus ntawm kev lag luam tsheb thoob ntiaj teb thiab kev thauj mus los. Lub tsheb tsav tsheb uas muaj 5G thev naus laus zis tuaj yeem ua tiav kev tsav tsheb nyab xeeb dua thiab kev caij tsheb xis dua. Kev xa xov tooj 5G sai dua yuav muab sijhawm ntau dua rau lub tsheb los muab cov lus taw qhia thiab kev ua tiav, yog li ua kom muaj kev nyab xeeb ntawm kev tsav tsheb thiab muab kev tsav tsheb zoo dua.
Daim ntawv thov tseem ceeb hauv kev tsav tsheb tsis siv neeg yog millimeter wave radar sensors, uas feem ntau siv cov ntaub ntawv xws li RO3003G2TM, RO3003TM, RO4830TM, CLTE-MWTM, thiab lwm yam. Lawv siv dav hauv 77GHz millimeter wave radar thiab muaj dielectric constant ruaj khov heev thiab ultra-low dissipation factor (qhov dissipation factor ntawm 0.001 feem ntau sim ntawm 10 GHz). Tib lub sijhawm, cov qauv tsis muaj iav fiber ntxiv txo qhov sib txawv ntawm dielectric constant hauv millimeter wave frequency band, Tshem tawm cov fiberglass effect ntawm lub teeb liab ntxiv ua rau theem ruaj khov ntawm lub radar sensor.
Nrog kev txhim kho ntawm cov radar sensors hauv 79 GHz zaus band (77-81 GHz), lawv cov teeb liab bandwidth dav dua tuaj yeem txhim kho qhov kev daws teeb meem ntawm radar sensors, nce lub kaum sab xis scanning, thiab txawm tias ua tiav 4D imaging.

Cov lus qhia txog cov lus qhia ntawm (Rogers) RO3003 ™ PCB zaus siab
(Rogers) RO3003™ Cov khoom siv ntau zaus yog cov khoom siv PTFE sib xyaw uas muaj cov khoom siv ceramics, siv rau PCBs hauv kev siv microwave thiab RF. Tus qauv tsim tshwj xeeb ua rau cov khoom siv ruaj khov thiab tshem tawm qhov kev hloov pauv ntawm dielectric constant ntawm cov khoom siv PTFE dav dav ntawm qhov kub thiab txias.
Rogers RO3003™ Cov khoom siv zaus siab tseem muaj cov dielectric constants ruaj khov (Dk: 0.00+/-0.04) thiab dissipation factor (Df: 0.0010 ntawm 10GHz) ntawm qhov kub thiab zaus sib txawv. Haum heev rau cov ntawv thov xws li automotive millimeter wave radar (77 GHz), advanced driving assistance systems (ADAS) thiab 5G wireless infrastructure (millimeter wave).
RO3003™ substrate muaj kev ruaj khov zoo heev, ua rau nws yooj yim rau cov neeg tsim qauv siv cov ntaub ntawv nrog cov dielectric constants sib txawv hauv ib txheej circuit thaum tsim cov multi-layer circuits yam tsis muaj teeb meem warping lossis kev ntseeg tau. Lub thermal expansion coefficient ntawm RO3003™ substrate hauv X/Y kev taw qhia yog 17/16 (ppm/℃). Tus nqi no yog sib npaug rau thermal expansion coefficient ntawm tooj liab, yog li tus nqi ib txwm ntawm etching shrinkage (ci tom qab etching) ntawm cov khoom yog tsawg dua 0.5mils/nti, qhia txog kev ruaj khov zoo heev. CTE hauv Z kev taw qhia yog 25 (ppm/℃), thiab txawm tias nyob rau hauv qhov kub thiab txias hnyav, cov khoom no tseem tuaj yeem ua kom muaj kev ruaj khov ntawm electroplated los ntawm qhov.
Daim Duab 1: Kev hloov pauv ntawm qhov kub thiab txias ntawm dielectric constant ntawm RO3003 thiab RO3035 laminates
Raws li pom hauv daim duab saum toj no, cov dielectric constants ntawm RO3003 thiab RO3035 laminates qhia tau tias muaj kev ruaj khov zoo nrog qhov kub thiab txias. Tsis muaj kev hloov pauv ntawm dielectric constant ntawm chav tsev kub zoo li PTFE iav fiber.
Daim Duab 2: Qhov sib txawv ntawm RO3003 thiab RO3035.
Daim duab saum toj no qhia txog kev faib tawm ntawm cov yam ntxwv dissipation hauv RO3003 thiab RO3035 laminates. RO3003-RO3035 Txoj kev sim: IPC-TM-65025.5.5 Cov xwm txheej sim: 10 GHz 23 °C.
