Ihiganwa rya PCB

Niki kibaho cyumuzunguruko cyinshi, kandi ni izihe nyungu zumurongo wumuzunguruko wa PCB? Nkuko izina ribigaragaza, ikibaho cyumuzunguruko cyinshi bivuze ko ikibaho cyumuzunguruko gifite ibice birenga bibiri gishobora kwitwa ibice byinshi. Nasesenguye ikibaho cyumuzingi wibice bibiri mbere, kandi ikibaho cyumuzunguruko cyinshi kirenze ibice bibiri, nkibice bine, ibice bitandatu, igorofa ya munani nibindi. Byumvikane ko ibishushanyo bimwe ari imirongo itatu cyangwa ibice bitanu byumuzunguruko, byitwa kandi ibice byinshi byumuzunguruko wa PCB. Kinini kuruta igishushanyo mbonera cyicyerekezo cyibice bibiri, ibice bitandukanijwe no kubika insimburangingo. Nyuma ya buri cyiciro cyumuzingi cyacapwe, buri cyiciro cyumuzenguruko cyuzuzanya no gukanda. Nyuma yibyo, gucukura umwobo bikoreshwa kugirango umenye imiyoboro hagati yumurongo wa buri cyiciro.
Ibyiza byibibaho byinshi byumuzunguruko wa PCB ni uko imirongo ishobora kugabanywa mubice byinshi, kugirango ibicuruzwa byinshi bishoboke. Cyangwa ibicuruzwa bito birashobora kugerwaho nibibaho byinshi. Nka: ibibaho byumurongo wa terefone igendanwa, umushinga wa micro, ibyuma bifata amajwi nibindi bicuruzwa bisa nkibinini. Mubyongeyeho, ibice byinshi birashobora kongera ubworoherane bwibishushanyo, kugenzura neza impedance itandukanye hamwe nimbogamizi imwe, hamwe nibisohoka byiza bya signal zimwe.
Imirongo myinshi yumuzunguruko nigicuruzwa byanze bikunze byiterambere ryikoranabuhanga rya elegitoronike mu cyerekezo cyihuta, imikorere myinshi, ubushobozi bunini nubunini buto. Hamwe niterambere ryiterambere ryikoranabuhanga rya elegitoronike, cyane cyane mugukoresha kwagutse kandi byimbitse gukoresha imiyoboro minini na ultra-nini nini nini ihuriweho, imiyoboro myinshi icapye igenda itera imbere byihuse mu cyerekezo cy’ubucucike bukabije, busobanutse neza, n’umubare wo hejuru. . , Impumyi ihumye yashyinguye umwobo muremure uburebure bwa aperture nubundi buryo bwikoranabuhanga kugirango uhuze isoko.
Bitewe no gukenera umuvuduko mwinshi muri mudasobwa ninganda zo mu kirere. Birasabwa kongera ubwinshi bwipfunyika, hamwe no kugabanya ingano yibice bitandukanijwe hamwe niterambere ryihuse rya mikorobe, ibikoresho bya elegitoronike biratera imbere muburyo bwo kugabanya ingano nubuziranenge; bitewe no kugabanya umwanya uhari, ntibishoboka kubibaho byanditseho impande zombi kandi byanditseho impande ebyiri Byongeye kwiyongera mubucucike bwinteko bigerwaho. Kubwibyo, birakenewe gutekereza gukoresha imiyoboro myinshi yacapwe kuruta impande zombi. Ibi birema ibisabwa kugirango habeho imbaho ​​zumuzunguruko.
