Kuza kwa 5G imiyoboro yitumanaho rya terefone byakuruye ibiganiro bijyanye no kubaka imiyoboro yihuta ya digitale kwisi yose.Ba injeniyeri barimo gushakisha uburyo bwiza bwo kohereza ibimenyetso na frequence binyuze mubikoresho bisanzwe bigezweho kubibaho byacapwe (PCBs).

Intego yibikoresho byose bya PCB ni ugukwirakwiza amashanyarazi no gutanga insulation hagati yumuringa uyobora ibice.Ibikoresho bikunze kugaragara muri iri tsinda ni FR-4.Ariko, ibisabwa mubuyobozi bwawe byanze bikunze bizaterwa nibintu bitandukanye bya PCB.Igitabo cyo gutoranya ibikoresho bya PCB hepfo, cyakozwe na ABIS, uruganda rukora PCB rwumwuga ufite uburambe bwimyaka irenga 15, ruzakubwira icyo ugomba kureba mugihe cyubwoko butandukanye bwibikoresho bya PCB.

Igishushanyo mbonera cyumuzunguruko gisanzwe kirimo imiyoboro ya dielectric substrate yibanze kimwe na dielectric laminated layer.Ibice bya laminate bizabera umusingi wumuringa wumuringa nindege zingufu.Izi nzego, zikora nkizitandukanya hagati yumuringa uyobora umuringa mugihe ureka amashanyarazi, ikorwa mubikoresho bitandukanye bishingiye kumiterere yabyo.Ibipimo byinshi byihariye byifashishwa mu gusesengura imiterere yumuriro n amashanyarazi yibikoresho kugirango hamenyekane ibikoresho bikwiye bya substrate yibanze hamwe na laminate.Byongeye kandi, ibintu byongeweho nkimiterere yimiti nubukanishi bigomba gusuzumwa ukurikije buri muntu ku giti cye, kubera ko PCB ishobora gukoreshwa mu mashini n’ibigize bishobora guhura n’ubushuhe bwinshi cyangwa bigashyirwa ahantu hakeye bisaba PCB byoroshye.

Igipimo cya dielectric ihoraho (Dk) ikoreshwa mukumenya imikorere y'amashanyarazi ya PCB yihuta ibikoresho.Kugirango ukore nka insulation kumurongo wumuringa nindege zingufu, urashaka ibikoresho bifite agaciro ka Dk gake kubice bya PCB.Ibikoresho byatoranijwe bigomba kandi gukomeza Dk yayo ihamye nkuko bishoboka mugihe cyubuzima bwayo kumurongo utandukanye.Ibintu bigena imikorere yamashanyarazi yibikoresho bya dielectric bikoreshwa muri PCBs ni ubudakemwa bwikimenyetso na impedance.

Kuruhande rwa PCB, ubushyuhe buzakorwa kuko butwara amashanyarazi.Ibikoresho bizagabanuka kubiciro bitandukanye bitewe nubushyuhe bwumuriro ubu bushyuhe buzashyira kumurongo wohereza, ibice, nibikoresho bya dielectric.Byongeye kandi, ubushyuhe bushobora gutuma ibikoresho bimwe byaguka, bikaba bibi kuri PCBs kuko bishobora gutera kunanirwa no gucika.

Mugihe cyo gusuzuma imiti irwanya imiti, ubwoko bwibidukikije ikibaho cyumuzunguruko kizakoreshwa ni ngombwa.Ibikoresho wahisemo bigomba kugira imiti ikomeye yo kurwanya imiti no kwinjiza neza.Byongeye kandi, injeniyeri agomba gushakisha ibikoresho bifite flame retardant, bivuze ko bitazatwika amasegonda arenga 10 kugeza kuri 50 mugihe cyo gutwikwa.Ibice bya PCB birashobora kandi gutangira gutandukana kubushyuhe bwihariye, kubwibyo ni ngombwa kumenya igihe ibi bibaye.

Mugihe uhisemo ibikoresho byiza, gushora amafaranga akwiye, no kugenzura amakosa yakozwe, birashoboka cyane ko ufite imyaka myinshi yibikorwa bitarangwamo ibibazo uhereye kubibaho byacapwe.ABIS Inzitizi zitanga ubuziranenge bwanditse bwumuzingo.Buri PCB dutanga igiciro cyiza kandi cyubatswe neza.Kugira ngo umenye byinshi kuri PCBs, nyamuneka TWANDIKIRE .
