Ikibaho cyumuzingo cyacapwe (Ikibaho cyumuzunguruko, cyitwa PCB) ni substrate yo guteranya ibice bya elegitoroniki, kandi ni ikibaho cyacapwe kigizwe nu murongo uhuza ingingo hamwe nibice byacapishijwe kumurongo rusange ukurikije igishushanyo mbonera.Igikorwa nyamukuru cya PCB nugukora ibikoresho bitandukanye bya elegitoronike bigizwe numuyoboro wateganijwe mbere, gukina uruhare rwogukwirakwiza relay, ni urufunguzo rwibanze rwa elegitoronike rwibicuruzwa bya elegitoroniki.
Ubwiza bwogukora imbaho zicapye zumuzunguruko ntabwo zigira ingaruka gusa muburyo bwo kwizerwa kwibicuruzwa bya elegitoroniki, ahubwo binagira ingaruka kumarushanwa rusange yibicuruzwa bya sisitemu, PCB rero izwi nka "nyina wibicuruzwa bya elegitoroniki".
Kugeza ubu, ibicuruzwa bitandukanye bya elegitoronike nka mudasobwa bwite, terefone zigendanwa, kamera ya digitale, ibikoresho bya elegitoronike, ibikoresho byo kugendesha ibyogajuru, ibinyabiziga bitwara imodoka nizindi nzitizi, byose bikoresha ibicuruzwa bya PCB, bishobora kugaragara ahantu hose mubuzima bwacu bwa buri munsi.
Hamwe nigishushanyo mbonera cyimikorere itandukanye, miniaturizasi nuburemere bwibicuruzwa bya elegitoronike, ibikoresho bito byongewe kuri PCB, ibyiciro byinshi birakoreshwa, kandi imikoreshereze yubucucike bwibikoresho nayo iriyongera, bigatuma ikoreshwa rya PCB rigoye.
PCB yubusa Ubuyobozi binyuze mubice bya SMT (tekinoroji yubuso bwububiko), cyangwa binyuze muri DIP (inshuro ebyiri kumurongo) gucomeka mugikorwa cyose, byitwa PCBA (Inteko yubuyobozi bwacapwe).
