Ukukhiqiza i-RO3003 PCB

Ukukhiqizwa kwe-RO3003 PCB kwamabhodi e-radar kanye ne-mmWave kuncike ekuqineni kobukhulu njengoba kunjalo nangokucaciswa kwezinto. Lapho ama-trace, ama-feed kanye nezindiza zokubhekisela ziba zincane ngogesi, ukubekezelelana kokukhiqiza okwabelwe i-geometry eqediwe kuba yingxenye yomklamo we-RF. Ibhodi le-radar elingu-77 GHz lithengwa njengepulatifomu yesenzwa esisebenzayo, hhayi njengeshidi le-RO3003. Ekugcineni ikhasimende likhathalela ukulungiswa kwe-antenna, isigaba se-feed-network, ukulahlekelwa kokubuyiselwa kokuqalisa, ukufana kokuhlanganiswa kanye nokusebenza kwe-radar ngaphezu kokushisa. Yingakho umhlinzeki we-radar PCB kumele alawule uchungechunge lokubekezelelana oluphelele esikhundleni sokwethula ithebula ledatha le-laminate njengobufakazi bokukwazi.

I-Highleap Electronics isekela ama-prototype e-radar PCB e-RO3003 kanye nokwakhiwa komkhiqizo, okuhlanganisa ukwenziwa kwe-thin-core, ukubhaliswa kwe-antenna, ukulungiswa kwembobo ehambisana ne-PTFE, ithusi elilawulwayo, ukuhlanganiswa kwe-RFIC kanye nokulinganiswa kwesihloko sokuqala okuvunyelwene ngakho. I-Highleap Electronics ihlela ukubuyekezwa kokukhiqiza mayelana nezinqumo ezinquma ukuthi i-prototype ye-radar ingaba uhlelo lokukhiqiza oluphindaphindwayo.

Amabhodi e-RO3003 e-RF ehlanganisiwe kanye nezakhiwo ze-radar alawulwa ngokuzungeza i-geometry ye-RF ekhishwe. Ukubuyekezwa kokwenziwa kugxile kakhulu ekwakhiweni kwe-dielectric, ubukhulu be-antenna noma umugqa wokudlulisela, ukubhoboza kanye nokubhaliswa ukuze ibhodi elenziwe lihlale lihambisana nemodeli yokuklama.

Kungani i-RO3003 isetshenziswa ku-PCB ye-Automotive Radar

I-RO3003 ihlanganisa ukulahlekelwa okuphansi kwe-dielectric, ukuziphatha kwe-dielectric okulawulwayo kanye nokwakhiwa kwe-PTFE egcwele ingilazi engenangilazi. Lezi zakhiwo ziwusizo ku-radar engu-76-81 GHz ngoba izici ze-antenna kanye nenethiwekhi yokuphakelayo zincane ngokwanele ukuthi ukuhlukahluka kwezinto zasendaweni kanye ne-geometry kushintshe isigaba, i-impedance kanye ne-resonance. Ukukhetha izinto kunciphisa iqembu elilodwa lezinto eziguquguqukayo, kodwa akususi isidingo sokulawula ithusi, ukujiya, umsebenzi wobuciko kanye nokuhlanganiswa. Ngezinhlelo zokusebenza ze-radar yezimoto, izidingo ze-Rogers PCB eziqondene ne-radar kufanele zichaze imingcele ye-antenna kanye nokuqinisekiswa okuzungeze ukukhetha izinto.

Uchungechunge lokubekezelelana kwe-radar

Kumaza e-mmWave, iphutha elinobukhulu obubukeka buncane ku-PCB evamile lingaba likhulu ngogesi. Umdwebo wokukhiqiza kufanele ukhombe ubukhulu be-RF obulawula ukugqama kwe-antenna, ukuxhuma kanye nesigaba. Kufanele futhi kusungule ama-datum avamile phakathi kwephethini ye-antenna, uhlaka oluqondisiwe, izici zezindlu kanye namathuluzi okuhlanganisa.

Ngokuphathelene nomongo wesistimu ngale kwe-laminate, amakhasi e -PCB ye-radar yezimoto ye-Highleap kanye ne -millimeter-wave radar PCB ahlanganisa ukwakheka kwamamojula, ukuhlanganiswa kwe-antenna kanye nokucatshangelwa kokukhiqiza.

Ububanzi bezinto ezibonakalayo: igama lomkhiqizo weRogers lisetshenziselwa ukuhlonza i-laminate echazwe ekwakheni i-PCB. I-Highleap Electronics inikeza ukwenziwa nokuhlanganiswa kwe-PCB, kuyilapho i-laminate itholakala futhi iqinisekiswa ngokwehlukana.

Izinselele Zokukhiqiza ze-RO3003 Radar PCB

Indlela yokwenziwa kumele igcine i-geometry esetshenziswa kumodeli ye-electromagnetic. Lokhu kuqala ngokuqinisekiswa kwezinto kanye nokubuyiselwa kwephaneli, bese kuqhubeka ngokuthwebula izithombe, ukuqopha, ukubhoboza, ukusebenza kwemigodi, ukucwebezela, ukuhambisa kanye nokuhlolwa kokugcina. Inzuzo ye-radar ayikwazi ukunqunywa kusuka kukhuphoni ye-impedance eqondile kuphela ngoba i-array kanye nokuqaliswa kungase kwehluleka ngenkathi ikhuphoni idlula.

Ama-cores amancane kanye nokukhetha kwethusi

Ukwakhiwa kwe-RO3003 okuncane kuthuthukisa ukuqina futhi kungasekela izakhiwo ezihlangene kahle, kodwa kwandisa ukuzwela ekujiyeni kwethusi, iphrofayili ye-etch kanye nokuphathwa. I-foil yethusi kufanele ikhethwe ngaphambi kokuba umklamo uqandiswe. I-foil ebushelelezi inganciphisa ukulahlekelwa umqhubi, kuyilapho ithusi lokugcina elifakwe insimbi lisashintsha ububanzi bomugqa kanye negebe. Uma imodeli ithatha ithusi elingenalutho kodwa ukukhiqizwa kufaka phakathi ukuqeda phezu kwesici esibalulekile, impendulo ingase ishintshe.

Ukubhoboza nokusebenza okuhambisana ne-PTFE

I-RO3003 idinga umzila wokwenziwa ofanele i-PTFE egcwele i-ceramic. Amapharamitha okubhoboza, ukususwa kwe-smear noma ukusebenza kwendawo, ukulungiswa kwemigodi nodonga kanye nokunamathela kwe-plating kumele kulawulwe ndawonye. Amabhodi amancane e-radar angasebenzisa imigodi embalwa, kodwa yonke inguquko yomhlabathi kanye nokuqaliswa kwayo isathinta ukubuya kwamanje kanye nokuvikela. Ikhwalithi yomphetho nayo ibalulekile lapho uhlaka luchaza khona isikhala se-antenna noma lufanelana nendlu ekhiqizwe ngomshini.

Ukwenziwa kwemvamisa ephezulu kuncike ezinqumweni zethusi kanye nokuqeda. Bheka i-copper foil kanye nokuqeda kobuso be-PCB yemvamisa ephezulu ukuze uthole ukuxhumana phakathi kwephrofayili yomqhubi, i-plating kanye nokulahlekelwa yi-RF.

Kusukela ku-RO3003 Prototype PCB kuya ekukhiqizweni

I-prototype ye-radar kufanele iphathwe njengokwakhiwa kokuxhumana. Umgomo ukuxhuma imodeli yokuklama nobukhulu obuqediwe kanye nokusebenza kwe-RF okuhlanganisiwe, bese unquma ukuthi yiziphi izilawuli okumele zihlale kuzo zonke izindawo zokukhiqiza. Isihloko sokuqala singafaka ukubika kobukhulu obubalulekile, i-microsection, i-impedance noma ukuqinisekiswa komugqa, izilinganiso zokuqalisa kanye nokuhlolwa kwe-radar yezinga le-module noma i-S-parameter okunikezwe ikhasimende noma okuvunyelwene ngakho nefektri.

Ukulawulwa kokushintsha kwezinto zokwakha kanye nokwakhiwa

I-RO3003, i-RO3003G2 kanye nezinye i-radar laminates azikwazi ukushintshaniswa ngaphandle kokubuyekezwa. Ukushintsha kungashintsha i-Dk, ukwakhiwa kwethusi, ukuziphatha kobukhulu, umzila wokucubungula kanye nobukhulu obutholakalayo. Ukuqokwa kwezinto ezivunyiwe kanye nokubuyekezwa komhlinzeki kufanele kuhlale kumadokhumenti okugcina kanye nokuthenga. Uma kuphakanyiswa ushintsho, kufanele luhlolwe ngokumelene nomodeli okhishwe kanye nohlelo lokufaneleka. Ukuqhubekela ezidingweni zokwenziwa kwe-RO3003G2 kufanele kusekelwe idatha eqondile ye-laminate kanye noshintsho lokwakhiwa oluvunyiwe.

Iphakheji yokufaneleka ye-Radar PCB

Ukukhishwa komkhiqizo kufanele kubonise ibhendi yerada, ubukhulu obubalulekile, ukwakhiwa kwethusi, ukuhlanganiswa okuqediwe, ukuqeda ubuso, ukugcina imaski, izidingo zokubhoboza kanye nokudlula, ama-data e-outline, amakhuphoni okuhlola kanye ne-interfaces yokuhlanganisa. Kumamojula erada ahlanganisiwe, iphakheji kufanele futhi ifake i-BOM, idatha yokubeka, okulindelwe yi-stencil, izilawuli zomswakama, ukuphathwa kwe-RFIC kanye nemikhawulo yokuhlola. I-Highleap ibuyekeza ukwakhiwa kwezingqimba, incazelo yethusi, ngokuguqulwa kanye nokuqeda ubuso ngesakhiwo se-RF. Kuma-antenna noma izakhiwo ze-mmWave, isihloko sokuqala kufanele siqhathaniswe nokwakhiwa okulingisiwe kunokuba kwahlulelwe kuphela ngokuhlolwa okubonakalayo. Amanani empahla eqondile kufanele ahlolwe ngokumelene nemibhalo yamanje yomhlinzeki webanga elicacisiwe kanye nokwakhiwa.

I-Highleap ingaxhumanisa ukukhiqizwa kwebhodi elingenalutho ne -BGA kanye nokuhlanganiswa kwe-PCB okune-pitch encane lapho i-radar IC noma iprosesa idinga ukubekwa okulawulwayo kanye nokugeleza kabusha. Uhlelo lwephrothokholi, uhlelo oluphansi kanye nohlelo lokukhiqiza oluphindaphindwayo luyaqinisekiswa ngemuva kokutholakala kwezinto kanye nobubanzi bokufaneleka bubuyekezwa.

Imibuzo yokukhiqiza i-radar

Ingabe i-RO3003 yodwa yanele ukusungula ukusebenza kohlelo lwe-77 GHz? Cha. I-geometry ye-antenna, ithusi, ukwakheka kokuqalisa, ukuhlanganiswa kanye nendlu kusalokhu kuyingxenye yohlelo lwe-RF.

Ingabe i-antenna kufanele imbozwe yi-solder mask? Kuphela uma imodeli yomklamo kanye nokuqinisekiswa kufaka phakathi isimo esiqondile se-mask. Izakhiwo eziningi ze-radar zisebenzisa i-defined mask-outs.

Yini okufanele ilinganiswe esihlokweni sokuqala? Impendulo incike ekwakhiweni, kodwa ubukhulu obubalulekile, ukujiya kwe-core, ukubhaliswa, ukuziphatha kokuqalisa kanye nokusabela kwe-RF okuhlanganisiwe kuvame ukuba usizo kakhulu kunokuqhubeka kuphela. Ukuze uthole ikhotheshini, faka ibhendi yokusebenza, i-stackup, ukujiya kwebhodi, ithusi, izici zokulawula ukuvimba kanye nendlela yokuhlola i-RF. Leyo mininingwane ivumela umenzi ukuthi abize ukunemba kwangempela okudingekayo ekwakhiweni kwe-RO3003.
