Ibikoresho
Nkumuntu utanga tekinoroji ya PCB itandukanye, ingano, kuyobora igihe cyo guhitamo, dufite guhitamo ibikoresho bisanzwe hamwe numuyoboro mugari wubwoko butandukanye bwa PCB ushobora gutwikirwa kandi uhora uboneka munzu.
Ibisabwa kubindi cyangwa kubikoresho byihariye nabyo birashobora kuzuzwa mubihe byinshi, ariko, ukurikije ibisabwa nyabyo, hashobora gukenerwa iminsi igera ku 10 yakazi kugirango ugure ibikoresho.
Twandikire natwe hanyuma muganire kubyo ukeneye hamwe numwe mubigurisha cyangwa itsinda rya CAM.

IKIBAZO Uburyo bwo Kugerageza Uruzitiro Rurenze kandi Bifitanye isano
Nigute ushobora kugerageza urukuta rw'umwobo hamwe n'ibisobanuro bifitanye isano?Urukuta rw'imyobo rukuraho ibitera n'ibisubizo?
Ikizamini cyo gukurura urukuta cyakoreshejwe mbere kubice byacukuwe kugirango byuzuze ibisabwa.Ikizamini rusange nugurisha umugozi kurubaho rwa pcb unyuze mu mwobo hanyuma ugapima agaciro ko gukuramo ukoresheje metero ya tension.Amasezerano yuburambe, indangagaciro rusange ziri hejuru cyane, bigatuma ntakibazo gihari mubisabwa.Ibicuruzwa biratandukanye ukurikije
kubisabwa bitandukanye, birasabwa kohereza kuri IPC ibisobanuro bijyanye.
Ikibazo cyo gutandukanya urukuta ni ikibazo cyo gufatana nabi, muri rusange biterwa nimpamvu ebyiri zisanzwe, icya mbere ni ugufata nabi (Desmear) bituma impagarara zidahagije.Ibindi ni uburyo bwo gutunganya umuringa utagira amashanyarazi cyangwa zahabu itunganijwe neza, Urugero: gukura k'umubyimba mwinshi, munini bizavamo gufatana nabi.Nibyo, hari izindi mpamvu zishobora gutera ikibazo nkiki, icyakora ibi bintu byombi nibibazo bikunze kugaragara.
Hano haribibi bibiri byo gutandukanya urukuta rwumwobo, icya mbere birumvikana ko ari ikizamini gikora ibidukikije bikabije cyangwa bikomeye, bizavamo ikibaho cya pcb kidashobora kwihanganira imihangayiko yumubiri kuburyo itandukanijwe.Niba iki kibazo kitoroshye kugikemura, birashoboka ko ugomba guhindura ibikoresho bya laminate kugirango ubone iterambere.
Niba atari cyo kibazo cyavuzwe haruguru, ahanini biterwa no gufatana nabi hagati y'umuringa n'umwobo.Impamvu zishoboka ziki gice zirimo gukomera bidahagije kurukuta rwumwobo, umubyimba ukabije wumuringa wa chimique, hamwe nudusembwa twa interineti twatewe no gufata nabi imiti yumuringa.Izi zose nimpamvu ishoboka.Birumvikana ko niba ubwiza bwo gucukura ari bubi, imiterere yimiterere yurukuta rwumwobo nayo ishobora gutera ibibazo nkibi.Kubijyanye nibikorwa byibanze byo gukemura ibyo bibazo, bigomba kuba kubanza kwemeza intandaro hanyuma ugakemura inkomoko yabitera mbere yuko bikemuka burundu.
