Binyuze kuri (VIA), uyu ni umwobo usanzwe ukoreshwa mu kuyobora cyangwa guhuza imirongo yumuringa wumuringa hagati yimiterere yimyitwarire mubice bitandukanye byubuyobozi bwumuzunguruko.Kurugero (nkibyobo bihumye, umwobo washyinguwe), ariko ntushobora gushyiramo ibice biganisha cyangwa umuringa usize umuringa wibindi bikoresho bishimangira.Kuberako PCB ikorwa no kwegeranya ibice byinshi byumuringa, buri gice cyumuringa kizaba gitwikiriwe nigice cyiziritse, kugirango ibice byumuringa bidashobora kuvugana, kandi guhuza ibimenyetso biterwa no kunyura mu mwobo (Via ), nuko hariho umutwe wigishinwa ukoresheje.
Ikiranga ni: kugirango uhuze ibyifuzo byabakiriya, unyuze mu mwobo wibibaho byumuzunguruko ugomba kuzuzwa umwobo.Muri ubu buryo, mugikorwa cyo guhindura inzira ya aluminiyumu icomeka inzira, mesh yera ikoreshwa kugirango yuzuze mask yagurishijwe hamwe nu mwobo wacometse ku kibaho cyumuzunguruko kugirango umusaruro uhamye.Ubwiza bwizewe kandi gusaba biratunganye.Vias ahanini igira uruhare rwo guhuza no kuyobora imiyoboro.Hamwe niterambere ryihuse ryinganda za elegitoroniki, ibisabwa bihanitse nabyo bishyirwa mubikorwa hamwe na tekinoroji yo hejuru yububiko bwacapwe.Inzira yo gucomeka ikoresheje umwobo irakoreshwa, kandi ibisabwa bikurikira bigomba kuba byujujwe icyarimwe: 1. Hano hari umuringa unyuze mu mwobo, kandi masike yo kugurisha irashobora gucomeka cyangwa ntayo.2. Hagomba kuba amabati hamwe nisasu mu mwobo, kandi hagomba kubaho umubyimba runaka (4um) ko nta wino ya mask yo kugurisha ishobora kwinjira mu mwobo, bikavamo amasaro yihishe mu mwobo.3. Binyuze mu mwobo bigomba kuba bifite umucuruzi wacururizaga ucomeka, opaque, kandi ntugomba kugira impeta zamabati, amasaro y amabati, hamwe nibisabwa.
Umwobo uhumye: Ni uguhuza umuzenguruko wo hanze muri PCB hamwe nigice cyimbere cyegeranye mugushiraho umwobo.Kuberako impande zinyuranye zidashobora kuboneka, byitwa impumyi zinyuze.Mugihe kimwe, murwego rwo kongera imikoreshereze yumwanya hagati yumuzunguruko wa PCB, hifashishijwe impumyi.Nukuvuga, unyuze mu mwobo kugeza hejuru yubutaka bwacapwe.
Ibiranga: Ibyobo bihumye biherereye hejuru no hepfo yubutaka bwumuzunguruko hamwe nubujyakuzimu.Byakoreshejwe muguhuza umurongo wubuso n'umurongo w'imbere hepfo.Ubujyakuzimu bw'umwobo mubusanzwe ntiburenza igipimo runaka (aperture).Ubu buryo bwo kubyaza umusaruro busaba kwitondera byumwihariko ubujyakuzimu (Z axis) kugirango bibe byiza.Niba utitondeye, bizatera ingorane zo gukwirakwiza amashanyarazi mu mwobo, kuburyo hafi nta ruganda rubyemera.Birashoboka kandi gushyira ibice byumuzingi bigomba guhuzwa mbere murwego rwumuzunguruko.Imyobo yabanje gucukurwa, hanyuma ikomatanyirizwa hamwe, ariko harasabwa ibikoresho byukuri byo guhuza no guhuza.
Viyasi yashyinguwe ni ihuriro hagati yumuzunguruko uwo ariwo wose imbere muri PCB ariko ntabwo ihujwe nuburyo bwo hanze, kandi bivuze kandi binyuze mumyobo itaguka hejuru yubuyobozi bwumuzunguruko.
Ibiranga: Iyi nzira ntishobora kugerwaho mugucukura nyuma yo guhuza.Igomba gucukurwa mugihe cyurwego rwumuzunguruko.Ubwa mbere, igice cyimbere gihujwe igice hanyuma amashanyarazi mbere.Hanyuma, irashobora guhuzwa rwose, ikaba iyobora kurusha umwimerere.Imyobo hamwe nu mwobo uhumye bifata igihe kinini, igiciro rero nicyo gihenze cyane.Ubu buryo busanzwe bukoreshwa gusa kubibaho byumuzunguruko mwinshi kugirango wongere umwanya ukoreshwa wizindi nzego
Mubikorwa byo kubyara PCB, gucukura ni ngombwa cyane, ntabwo ari uburangare.Kuberako gucukura ari ugucukura ibyasabwaga binyuze mu mwobo ku mbaho zometseho umuringa kugirango utange amashanyarazi kandi ukosore imikorere yigikoresho.Niba imikorere idakwiye, hazabaho ibibazo murwego rwo kunyura mu mwobo, kandi igikoresho ntigishobora gukosorwa ku kibaho cy’umuzunguruko, kizagira ingaruka ku mikoreshereze, kandi ikibaho cyose kizaseswa, bityo inzira yo gucukura ni ngombwa cyane.
