Ibi bivuze iki kubikoresho byihuta bya PCB?
Mbere ya byose, mugihe ushushanya no kubaka ibirindiro bya PCB, ibintu bifatika bigomba gushyirwa imbere. 5g PCbs igomba kubahiriza ibisobanuro byose mugihe utwaye no kwakira ibizamini, atanga amashanyarazi, no gutanga kugenzura imirimo yihariye. Byongeye kandi, ibibazo bya PCB bizakenera gukemurwa, nko kubungabunga ubunyangamugayo kumuvuduko mwinshi, ubuyobozi bwubushyuhe, nuburyo bwo gukumira kwivanga kwivanga (eMI) hagati yamakuru nimbaho.
Ibimenyetso bivanze Kwakira Igishushanyo mbonera cyumuzunguruko
Uyu munsi, sisitemu nyinshi zijyanye na 4G na 3g PCB. Ibi bivuze ko ibice byohereza kandi wakire urwego rwinshi ni 600 MHz kugeza 5.925 GHZ, hamwe numuyoboro wa Barwidth ni 20 MHZ kuri sisitemu ya iot. Iyo ushushanya PCB ya 5G ya sisitemu ya 5G, ibi bice bizakenera imirongo milimeter ya 28 ghz, 30 ghz cyangwa 77 ghz, bitewe nibisabwa. Ku miyoboro igwidth, sisitemu ya 5G izatunganya 100mhz munsi ya 6GHz na 400mhz hejuru ya 6GHz.
Iyi mbuto yo hejuru ninshuro nyinshi zizakenera gukoresha ibikoresho bikwiye muri PCB kugeza icyarimwe no kohereza ibimenyetso byo hepfo no kohereza ibimenyetso byo hasi kandi hejuru nta gutakaza ibimenyetso na EMI. Ikindi kibazo nuko ibikoresho bizahinduka byoroshye, byoroshye, kandi bito. Kubera uburemere bukabije, ingano nimbogamizi zo mu kirere, ibikoresho bya PCB bigomba guhinduka no kwizirika kwakira ibikoresho byose bya microelectronic ku kibaho cy'umuzunguruko.
Kuri PCB umuringa, ibimenyetso byoroheje kandi kugenzura amakosa bigomba gukurikizwa. Inzira gakondo ya etching ikoreshwa kuri 3G na 4G ryihuta cyane PCB irashobora guhindurwa muburyo bwo kwahinduwe igice cyahinduwe. Ibi bisobanuro bya kimwe cya kabiri cyongeraho bizatanga byinshi byukuri ninkuta zigororotse.
Urufatiro rwibikoresho narwo rurimburwa. Amasosiyete yacapweko Amasosiyete akaba yacapwe niga ibikoresho hamwe nubushake buhoraho nka 3, kuko ibikoresho bisanzwe kugirango PCB yihuta cyane ari 3.5 kugeza 5.5. Ikirahure kibisi cyirahuri, igihombo cyo hasi gitunguranye, umuringa wihariye umuringa uzahinduka amahitamo yo kwihuta pcb, bityo akabuza igihombo cyibimenyetso no kuzamura ubunyangamugayo.
Ikibazo cya EMI
EMI, CrosStalk hamwe nubushobozi bwa parasitike nibibazo nyamukuru byimbaho. Kugirango uhangane na Crostalk na EMI bitewe numurongo wa Analog na Digital kuri The Conanty, birasabwa cyane gutandukanya ibimenyetso. Gukoresha imbaho nyinshi zizatanga ibisobanuro byiza kugirango umenye uburyo bwo gushyiramo ibice byihuta cyane kugirango inzira zinzira zidasanzwe zihagarikwa, mugihe ibimenyetso bya AC na DC bitandukanya. Ongeraho ikingira no kuyungurura mugihe ushyira ibice bigomba no kugabanya umubare wa emi kuri PCB.
Kugirango tumenye neza ko nta nenge zigufi kandi zifungura imirongo migufi cyangwa ifunguye imirongo yubugenzuzi bwa copper, inoze ihamye (aio) hamwe na metrologiya yo hejuru na 2D izakoreshwa kugirango igenzure ibikurikira kandi ikabapima. Iyi tekinoroji izafasha abakora PCB gushakisha uburyo bwo gutesha agaciro ibimenyetso.
Inzitizi zo mu bushyuhe
Umuvuduko mwinshi wibimenyetso bizatera ikigezweho binyuze muri PCB kugirango utanga ubushyuhe bwinshi. Ibikoresho bya PCB kubikoresho byimirire nibice byibanze bizakenera gukemura bihagije umuvuduko mwinshi usabwa nikoranabuhanga rya 5G. Niba ibikoresho bidahagije, birashobora gutera ibimenyetso byumuringa, gukuramo, kugabanuka no kurwana, kuko ibyo bibazo bizatera PCB kwangirika.
Kugirango uhangane nubushyuhe bwo hejuru, ababikora bazakenera kwibanda ku guhitamo ibikoresho bikemura ibibazo byubushyuhe nibibazo byumva neza. Ibikoresho hamwe nubushyuhe bwo hejuru, kwimura ubushyuhe buhebuje, hamwe nubuzima buhoraho bugomba gukoreshwa mugukora pcb nziza kugirango utange ibiranga 5G bisabwa kuriyi porogaramu.
