Ukwenziwa kwe-PCB ye-RO4725JXR

Ukwenziwa kwe-PCB ye-RO4725JXR yamabhodi e-antenna e-PIM ephansi kuncike ekugcineni izindawo ze-RF kanye nezixhumi zemishini zihambisana. I-PIM ephansi iyisici sokuhlanganiswa okuqediwe, ngakho-ke ukukhethwa kwe-laminate, i-geometry yethusi, ukuqeda, ukuhlanzeka kanye nezixhumi ze-connector kufanele kusebenze ndawonye. Ukwenziwa kwe-PCB ye -Rogers RO4725JXR kukhethwa amabhodi e-antenna lapho i-PIM ephansi, ukufana kwephaneli, kanye nokuziphatha kwe-RF okuphindaphindwayo kubalulekile. I-RO4725JXR iyi-laminate ye-antenna ye-Dk 2.55 esetshenziswa ekwakhiweni kwesiteshi sesisekelo, i-antenna esatshalaliswa, kanye nemiklamo ye-antenna ye-array. Ukubhalwa kwe-Rogers kubeka i-RO4725JXR ye-PIM encishisiwe kanye nokulahlekelwa kokufakwa okuphansi, kanye nokusebenza kwe-PIM okuphansi okubonisiwe okungcono kune--160 dBc ngaphansi kwesimo sokuhlola esishiwo. I-Highleap Electronics ibuyekeza i-laminate callout, uhlelo lwethusi, ukwakheka kwephaneli, i-plating, ukuqeda kwe-solder, izindawo ze-connector, kanye namarekhodi okuhlola ngaphambi kokukhishwa kokukhiqiza.

Okuqukethwe

1. Uma i-RO4725JXR iyi-Antenna PCB Material efanele
2. I-PIM Ephansi Ixhomeke Ekuhlanzekeni Kokukhiqiza, Hhayi Igama Le-Laminate Kuphela
3. Izakhiwo Zezinto Ezithinta Ukukhiqizwa
4. Isibuyekezo se-DFM kanye ne-Stackup Ngaphambi Kokucaphuna
5. Izilawuli Zenqubo Yokukhiqiza
6. Iphakheji ye-RFQ kanye namarekhodi okukhiqiza

Ububanzi bezinto ezibonakalayo: Leli khasi liphathelene nokwakhiwa kwe-PCB kusetshenziswa izinto ezishiwo yiRogers. I-Highleap Electronics ikhiqiza ibhodi eliqediwe kanye ne-PCBA; ukukhiqizwa kwe-laminate kanye nokuthengiswa kwezinto ezibonakalayo kungaphandle kobubanzi besevisi yethu.

Uma i-RO4725JXR iyi-Antenna PCB Material efanele

I-RO4725JXR isetshenziselwa amabhodi e-antenna adinga ukulahlekelwa okuphansi, ukuziphatha okuzinzile kwe-dielectric, ukucutshungulwa okungenalo i-lead, kanye nokulawulwa okucophelelayo kwe-intermodulation. Ibaluleke kakhulu kuma-antenna asesiteshini esiyisisekelo, izinhlelo ze-antenna ezisatshalaliswayo, amanethiwekhi okuphakelayo e-RF, kanye nehadiwe yokuxhumana yangaphandle lapho iphutha elincane endleleni yamanje lingathinta ukusebenza kokugcina kwe-RF.

Ukukhetha izinto kufanele kuhlotshaniswe nesidingo se-antenna esiqediwe. Uma umkhiqizo uzohlolwa i-PIM, umdwebo we-PCB kanye ne-RFQ kufanele kuhlonze ithagethi, isixhumi esibonakalayo, ukuqeda kwendawo, izici zethusi, imfuneko yokuhlanza, nokuthi ngabe umhlinzeki unesibopho sokuhlanganiswa yini. Le mininingwane ibaluleke kakhulu kunokumane uqambe i-laminate. Uma uhlu olufushane lwezinto ze-antenna luhlanganisa ne-RO4533, ukuqhathanisa i-laminate ye-antenna ye-RO4533 kufanele kusebenzise imodeli yemvamisa ehlukile kanye nencazelo yebhodi.

I-PIM Ephansi Ixhomeke Ekuhlanzekeni Kokukhiqiza, Hhayi Igama Le-Laminate Kuphela

Kumabhodi e-antenna, i-laminate ye-PIM ephansi iyindawo yokuqala kuphela. Ukushintshashintsha okungenamsebenzi kungathinteka ukungaqhubeki okuncane kanye nokuhlangana kwensimbi okungaphelele, okuhlanganisa i-copper plating engaguquki, izindawo zokuxhumana ezingcolisiwe, ama-connector pad aqinile, ama-solder joints aqhekekile, ama-burrs, i-hardware ekhululekile, noma ukuqeda okulinganayo. Yingakho ukukhiqizwa kwe-RO4725JXR kufanele kuphathwe njengenqubo ye-RF elawulwayo kunokuba kube yi-oda le-PCB elijwayelekile elinezingqimba ezimbili. Uma i-AD250C nayo ikhethwe njenge-antenna, ukwakhiwa kwe-antenna ye-AD250C ephansi ye-PIM kudinga izidingo zayo ze-geometry ye-dielectric evunyiwe, ithusi kanye nezixhumi.

Ukugxila okuningiliziwe ekukhiqizeni kufanele kube yindlela yamanje ye-RF. I-Highleap ihlola izici zethusi, izimbobo ezifakwe amapulangwe, ama-connector launch pads, i-solder mask clearances, imiphetho yendlela, ukuphathwa kwamaphaneli, izindawo zokunamathisela izixhumi, kanye nanoma yisiphi isixhumi esibonakalayo esingaba ukuxhumana okungekho emgqeni. I-burr encane enqenqemeni, i-launch pad eklwebhekile, noma insalela ezungeze indawo yesixhumi ingase ingabonakali ingathi sína ekuhlolweni okuvamile okubonakalayo, kodwa kungabaluleka ukuthi i-antenna eqediwe ilinganiswa nini nge-PIM.

Uma i-antenna iyingxenye yesiteshi sesisekelo, i-DAS, i-repeater, noma iyunithi ye-RF yangaphandle, i-RFQ kufanele isho ithagethi ye-PIM, uhlobo lwesixhumi, imvamisa yokuhlola, izinga lamandla, indlela yokwamukela, nokuthi ngabe i-Highleap icaphuna ukwenziwa kwe-PCB engenalutho kuphela noma ukuhlanganiswa kwe-PCB . Lolu lwazi lushintsha indlela umhlinzeki alawula ngayo ukuhlanza, ukupakisha, ukuvikelwa kwephedi yesixhumi, ukushiswa kwe-solder, kanye nokuhlolwa okuphumayo.

• Cacisa i-PIM target edingekayo kanye nendlela yokuhlola ngaphambi kokucaphuna ukuthi umkhiqizo oqediwe uzohlolwa nini yi-PIM.
• Vikela izindawo zokuqalisa izixhumi kanye nezindawo zokuthintana ekulimaleni, ezinsaleleni, ezimbotsheni, nasekuphathweni kabi.
• Buyekeza ihadiwe yokuhlanganisa kanye namajoyinti okusoda kanye nenqubo yebhodi elingenalutho, hhayi ngemva kokulethwa kwe-PCB.

Izakhiwo ze-RO4725JXR Ezihlobene Nokwenziwa Kwe-PIM Ephansi

Isibuyekezo se-DFM kanye ne-Stackup Ngaphambi Kokucaphuna

Isilinganiso esithembekile siqala ngesethi ephelele ye-Gerber, amafayela okubhoboza, uhlu lwe-net, uhlaka lwebhodi, umdwebo we-stackup, i-callout yezinto zokwakha, isisindo sethusi, ukuqeda kobuso, amanothi emaski e-solder, ama-impedance target, kanye nanoma yiziphi izidingo zokuhlanganisa. I-Highleap ihlola ukuthi umklamo ungenziwa ngokuphindaphindiwe yini ngaphambi kokuqala kwamathuluzi.

Izilawuli Zenqubo Yokukhiqiza

Indlela yenqubo kufanele ikhethwe ngaphambi kokuba izinto zikhishwe ukuze zikhiqizwe. Izilawuli ezijwayelekile zifaka phakathi ukuqinisekiswa kwezinto, ukuhlolwa kwesendlalelo sangaphakathi, ukubuyekezwa kwe-lamination, ikhwalithi yokubhoboza, ukulungiswa kwemigodi, i-copper plating, ukubhaliswa kwemaski ye-solder, ukuqeda kwendawo, ukunemba komzila, ukuhlolwa kukagesi, kanye nokuhlolwa kokugcina. I-Highleap ibuyekeza izici ze-antenna, incazelo yethusi, ukuqeda kwendawo kanye nokubhoboza kucatshangelwa izidingo ze-PIM ephansi. Lapho kudingeka ukuhlolwa kwe-PIM, indlela yokwamukela kufanele ifane nehadiwe ehlanganisiwe kunokuba ibhodi elingenalutho lodwa. Amanani empahla eqondile kufanele ahlolwe ngokumelene nemibhalo yamanje yomhlinzeki webanga elicacisiwe kanye nokwakhiwa.

Ukuze kuphindwe kwakhiwe nge-PIM ephansi, gcina ukuqeda kwendawo okuvunyelwe, indlela yokuhlanza, ukwakhiwa kwethusi, isixhumi esibonakalayo kanye namarekhodi ezinto ezingenayo. Izinguquko zenqubo kufanele zihlolwe ngendlela efanayo yokufaneleka kwe-RF kunokwamukelwa okuvamile kwebhodi elingenalutho kuphela.

Iphakheji ye-RFQ kanye namarekhodi okukhiqiza

Izinhlelo zokusebenza ezijwayelekile zifaka phakathi ama-antenna asesiteshini esiyisisekelo, ama-phased arrays, ihadiwe ye-DAS, amanethiwekhi okuphakelayo kwe-RF, amabhodi angasebenzi aphansi e-PIM, kanye nama-antenna subassemblies lapho izinguquko ezincane zenqubo zingathinta ukusebenza kwe-RF yezinga lesistimu.

Thumela amafayela e-Gerber, idatha yokubhoboza, uhlaka lwebhodi, ubukhulu be-RO4725JXR, isisindo sethusi, ukuqeda kobuso, amanothi emaski e-solder, izidingo zephaneli ye-antenna, imininingwane yokuxhuma, okulindelwe yi-PIM, ubuningi, kanye neshejuli yokukhiqiza.

Ngokwakhiwa kwe-RO4725JXR okune-PIM ephansi, ubufakazi obuwusizo bungafaka phakathi ukulandeleka kwezinto, amarekhodi okuphela kwendawo, izilawuli zokuhlanzeka, ukuhlolwa kwemishini kanye nendlela yokuhlola ye-RF esetshenziselwa ukwamukelwa kwe-PIM ephansi. Amadokhumenti kufanele amboze izimo zebhodi kuya kusixhumi kanye ne-metal-interface ezingathinta ukuhlanganiswa okuqediwe. Nge-RFQ, faka umdwebo we-antenna, ibhendi yemvamisa, i-PIM target, i-stackup, ukuqeda, imininingwane yesixhumi kanye nobuningi. Lokhu kunikeza umenzi umkhawulo ocacile wokukhiqiza kanye nokuhlolwa.
