Rogers Microwave RF Automotive Radar PCB
PCB-ga soo noqnoqonaya ee Millimeter Wave Automotive Radar
5G iyo safarka moobiilka ayaa ah wax soo saarka is dhexgalka qoto dheer ee warshadaha baabuurta oo leh tignoolajiyada macluumaadka jiilka cusub sida isgaarsiinta, sirdoonka macmal iyo xisaabinta waxqabadka sare ee IoTs. Waxay yihiin jihooyinka ugu muhiimsan ee horumarinta caqliga iyo iskuxiran ee gawaarida caalamiga ah iyo gaadiidka. Baabuurka iskii u madaxbannaan ee ku qalabaysan tignoolajiyada 5G waxa uu gaadhi karaa wadida badbaado leh iyo waayo-aragnimo raaxo leh. Gudbinta calaamadaha 5G ee ugu dhakhsaha badan waxay siin doontaa nidaamka gaadiidka wakhti dheeraad ah si ay u bixiyaan jawaab celin iyo habayn, si loo hubiyo badbaadada wadista iyo bixinta khibrad wadista oo hufan.
Codsiga ugu weyn ee wadista iskeed u madaxbannaan waa millimitirka hirarka radar-ka, kuwaas oo inta badan isticmaala qalabka sida RO3003G2TM, RO3003TM, RO4830TM, CLTE-MWTM, iwm. factor (cutubka kala daadsanaanta 0.001 ayaa inta badan lagu tijaabiyaa 10 GHz). Isla mar ahaantaana, qaab dhismeedka aan lahayn fiber galaas ayaa sii yareynaya kala duwanaanshaha joogtada ah ee dielectric maxaliga ah ee wareegga hirarka millimitirka, baabi'inta saameynta fiberglass ee calaamadda waxay sii kordhisaa xasilloonida wejiga dareenka radar.
Iyada oo horumarinta dareemayaasha radar ee 79 GHz band soo noqnoqda (77-81 GHz), baaxadda calaamadahooda ballaaran waxay sii wanaajin karaan xallinta dareemayaasha radar, kordhinta xaglaha iskaanka, iyo xitaa waxay gaaraan sawirka 4D.

Shaxda cabbirka qeexida ee (Rogers) RO3003™ PCB-ga soo noqnoqonaya
(Rogers) RO3003™ Substrates-yada soo noqnoqda ee sarreeya waa PTFE oo isku dhafan oo ay ka buuxaan ceramics, oo loo isticmaalo PCB-yada mikrowaytka ganacsiga iyo codsiyada RF. Naqshadaynta gaarka ah waxay siisay walxaha xasiloonida waxayna meesha ka saaraysaa isbeddelka tallaabada ee joogtada ah ee dielectric ee ujeeddada guud ee PTFE ee heerkulka qolka.
Rogers RO3003™ Substrate-ka soo noqnoqda ee sarreeya ayaa weli leh joogtooyin dielectric ah oo deggan (Dk: 0.00+/-0.04) iyo factor dissipation (Df: 0.0010 at 10GHz) heerkul kala duwan iyo soo noqnoqoshada. Aad ugu habboon codsiyada sida radar milimitirka baabuurta (77 GHz), nidaamyada kaalmada wadista horumarsan (ADAS) iyo kaabayaasha wireless 5G (mawjadaha millimitirka).
RO3003 ™ substrate wuxuu leeyahay xasillooni farsamo oo heer sare ah, taasoo ka dhigaysa mid ku habboon naqshadeeyayaasha inay adeegsadaan agabyo leh koronto kala duwan oo wareeg ah marka la naqshadeynayo wareegyada lakabyada badan iyada oo aan la isku halleyn karin ama la isku halleyn karin. Isku-dhafka fidinta kulaylka ee RO3003 ™ substrate ee jihada X/Y waa 17/16 (ppm/℃). Qiimahani waxa uu u dhigmaa iskudarka balaadhinta kulaylka ee naxaasta, markaa qiimaha caadiga ah ee etching yaraynta (dubidda ka dib etching) walaxda ayaa ka yar 0.5mils/inch, oo muujinaysa xasillooni cabbir heersare ah. CTE ee jihada Z waa 25 (ppm/℃), iyo xitaa jawiga heerkulka adag, maaddadani waxay weli xaqiijin kartaa xasilloonida korantada ee godadka.
Jaantus 1: Kala duwanaanshaha ku-tiirsanaanta heerkulka ee joogtada ah dielectric ee RO3003 iyo RO3035 laminates
Sida ku cad shaxanka kore, joogtooyinka dielectric ee RO3003 iyo RO3035 laminates waxay muujinayaan xasilooni wanaagsan oo heerkul ah. Ma jiro isbeddel tallaabo ah oo joogto ah dielectric heerkulka qolka sida fiber galaas PTFE.
Jaantus 2: Qodobka kala-baxa ee RO3003 iyo RO3035.
Jaantuska kore wuxuu muujinayaa qaybinta qodobbada kala daadsanaanta ee RO3003 iyo RO3035 laminates. RO3003-RO3035 Habka tijaabada: IPC-TM-65025.5.5 Xaaladaha tijaabada: 10 GHz 23 °C.
