Igishushanyo cya RF PCB kuva ku nyigisho kugeza ku bikorwa: Ubuyobozi bwuzuye bw'ubuhanga bwa Rich Full Joy
Mu nganda z'ikoranabuhanga zigenda zitera imbere vuba muri iki gihe, Igishushanyo cya PCB cya RF (Radio Frequency)bigira uruhare runini mu gutuma porogaramu zihuta cyane kandi zikora inshuro nyinshi nka Itumanaho rya 5G, IoT, indege, na radar y'imodokaNk'ikigo gifite uburambe buhanitse bw'imyaka myinshi mu ikoranabuhanga rya PCB rikoresha ikoranabuhanga rigezweho, Ibyishimo Byuzuye Bikungahayeyishimiye gusangira ibitekerezo by’abahanga ku bashushanya PCB bashaka guhangana n’ibibazo byo gushushanya inama za RF.
Ibimenyetso bya RF muri rusange bikora muri Intera iri hagati ya 300MHz na 300GHz, no gushushanya PCB kuri bene iyo miyoboro bitanga imbogamizi zidasanzwe zitagaragara muri sisitemu zikoresha umuvuduko muto. Muri zo harimo ubunyangamugayo bw'ikimenyetso, Guhagarika EMI, imikorere y'ibikoresho bya dielectric, na guhuza neza impedanceMuri iyi nyandiko yuzuye, turasuzuma uburyo bwiza n'ingamba zo gushushanya kugira ngo twubake PCB za RF zizewe kandi zikora neza.
Gusobanukirwa RF PCBs
An RF PCBni ikigo cy’itumanaho cyacapwe gikorera ku maradiyo, akenshi gihuza byombi ikoranabuhangana ibice bya analoge, bashinga icyo bita ikibaho cy'ibimenyetso bivanzeIkibazo kiri hano kiri mu gucunga imikoranire hagati y'ubwoko bw'ibimenyetso, kuko imiterere idakwiye ishobora gutera ibibazo bikomeye byo kubangamira no kugarura ishusho.
Biterwa na Gukoresha ingufu, RF PCBs zishobora gushyirwa mu byiciro bikurikira:
- PCB za RF zifite ingufu nke, bishyira imbere urusaku ruke n'uburyo ibimenyetso bifatwa
- PCB za RF zifite imbaraga nyinshi, bisaba imiterere ikomeye y'ubushyuhe n'imbaraga zidahindagurika
Buri cyiciro gisaba ibitekerezo byihariye mu gihe cyo gushushanya.
Amabwiriza y'ingenzi yo gushushanya PCB ya RF
1, Guhitamo Ibikoresho: Ishingiro ry'Imikorere ya RF
Guhitamo ibikoresho bya substrate bigira ingaruka zitaziguye ubunyangamugayo bw'ikimenyetso, guhagarara neza k'ubushyuhe, na guhuza kw'impedansimu ntera nini y'impinduka. Ibipimo by'ingenzi birimo:
Igipimo cy'ingufu z'ubushyuhe (CTE)
CTE igomba kuba ijyanye n'ibice bishyirwaho. Igipimo cyo kwaguka kidahuye gishobora gutuma ingingo z'icyuma zicika cyangwa zigacikamo ibice—cyane cyane muri PCB za RF z'urwego rwinshiIbi ni ingenzi ku nzego zizewe cyane nka indegena itumanaho.
Dielectric Constant (Dk)
Dr asobanura uburyo ibimenyetso bikwirakwira vuba. Sisitemu za RF zikunze gusaba ibikoresho bya Drk bike kandi bihamyekugira ngo hagenzurwe neza impedansi no kugabanya ubwiza bwayo. Muri 5G na milimetero-waveporogaramu, ibikoresho bya Dr bike nka RO4350Bcyangwa RT/duroidni byiza cyane.
Ikintu cyo gukwirakwiza (Df)
Df yerekana igihombo cya dielectric. Mu ihererekanya ry'amashanyarazi rikoresha frequency nyinshi, Df yo hasiNi ingenzi cyane kugira ngo hagabanywe kugabanuka kw'ibimenyetso no kubungabunga ubuziranenge bw'imiterere y'amajwi mu gihe cy'intera.
Inama y'inzobere:Ibikoresho nka RO4000, RO3000, na Laminate zishingiye kuri PTFEni ibipimo ngenderwaho mu nganda kuri RF PCB. Udupapuro tw'umuringa tworoshye kandi dufite ubukana buke nabyo bifasha kugabanya igihombo cy'ibimenyetso bivuye ku ngaruka z'uruhu.
2, Igishushanyo mbonera cya Layer Stackup cyakozwe neza
Gushyira hamwe kw'ibice bigira ingaruka ku kugabanya EMI, kudahungabana kw'impedansi, no kunoza uburyo ibimenyetso bikoreshwa.
Ishyirwa hagati y'ibice
Ibice bya RF bigomba gushyirwa ku murongo ukurikije imikorere yabyo n'urwego rw'imbaraga. Gumana umwanya uhagije hagati ya ibikoresho bikoresha ingufu nyinshina imiyoboro ya analoge igaragara cyanekugabanya kwivanga kw'ibintu no kunoza uburyo ubushyuhe bukwirakwira.
Imiterere yihariye
Irinde ibintu birebire cyangwa byatandukanijwe, bikora nk'aho antene zitagenzurwaNiba byanze bikunze, bigabanya ukoresheje uburyo bwo kurinda ubutaka cyangwa kugenzura uburebure bwabyo.
Gushyira ibice by'ingenzi mu bikorwa
Shyira ibice hakurikijwe urujya n'uruza rw'ikimenyetsona amatsinda y'imikorere. Imiyoboro migufi igabanya uburyo bwo gusohora ibimenyetso no gutakaza ibimenyetso. Tanga umwanya uhagije wo gupima no kongera gukoresha uburyo bwo kubigeraho.
Umubare w'Ibyiciro n'Imiterere
Koresha urwego rwo hejuru mu gukoresha RF, imiterere y'ubutaka hagati, n'urwego rwo hasi kugira ngo ubone imirongo y'ikoranabuhanga cyangwa umuvuduko muto. inzira zo kugaruka ku butaka bukomeyekugabanya uburyo bwo gusohora umuyoboro (loop inductance) n'uburyo bwo gupima (EMI).
Gukuraho Ingufu
Buri IC isaba gutandukanya ibintu mu buryo bw'ibanzekugira ngo uyungurure urusaku rw'ingufu. Shyira capacitors zo gukuraho uduce hafi y'udupira tw'ingufu, ukoreshe agaciro gakwiye ku bijyanye n'umuvuduko wa IC n'imiterere ya impedance.
3. Uburyo bwo gukoresha ikimenyetso cya RF neza
Uburyo bwo gukoresha RF ni siyansi. Intego ni ugukomeza impedansi igenzurwana kwangirika guke kw'ibimenyetso.
Komeza kumenya ibikurikira
Imirongo migufi ingana no kugabanya ubushobozi bwo gutekereza no kugarura ibitekerezo. Irinde ko inzira zinyuramo zidakenewe zihagarara.
Irinde inzira zinyura kuri parallel
Irinde ibimenyetso bya RF bihurirana n'ibitari ibya RF. Imirima ihujwe iyobora kuri kuganira ku buryo bunyuranyije n'amategekoNiba bidashoboka, ongera intera kandi ushyireho uburyo bwo kurinda ubutaka.
Sobanura amanota y'ikizamini
Amanota y'ikizamini agomba kuba bitandukanyijwe n'imirongo y'ibimenyetsokugira ngo hirindwe ko ibimenyetso bihindagurika mu gihe cyo kwemeza.
Smart Bends
Impande za RF zigomba kuba uruziga cyangwa uburebure, ntabwo ikarishye. Komeza uburebure bw'umurambararo bungana nibura Ubugari bwa 2x bw'ikimenyetsokugira ngo hirindwe ko ikimenyetso cyagaruka.
