Mugihe ibicuruzwa byabakiriya bigenda binini kandi bikomeye, abahuza, bakwiriye kugenzura ingufu nyinshi, bikoreshwa nkibikoresho byo guhinduranya imitwaro kubikoresho bitandukanye byamashanyarazi bisaba amashanyarazi menshi kandi menshi.
Ariko, hamwe nogukenera gukenerwa kubikoresho bito bito, byoroheje, kandi byoroheje, inzira yo gusimbuza abantu benshi hamwe n’ibikoresho bito, birebire - byacapishijwe icyapa cy’umuzunguruko (PCB) gishobora guhagarika umuyaga mwinshi n’umuvuduko mwinshi mubyukuri biriyongera.
Byongeye kandi, abakiriya bamwe, bategereje ko izamuka ry’ibikenerwa mu gihe kiri imbere ndetse n’umusaruro wiyongereye, bakoresha imashini ya PCB kugira ngo bagabanye ibiciro bahuza ibikoresho byo guhinduranya imizigo ku kibaho cyacapwe, nk'igipimo kimwe cyo kugabanya igihe cyo gukora.
Inzitizi zikomeye zo mumitekerereze kunesha mugusimbuza abahuza na rezo ya PCB ni ihinduka rikomeye ryibishushanyo bisabwa kugirango usimbuze insinga gakondo hamwe n "" ikibaho - ".
Icyerekezo cya PCB nigikoresho cyo kugenzura ibikoresho bya elegitoronike byinjijwe ku kibaho cyacapwe. Muguhuza relay hamwe ninama yumuzunguruko, imiterere yumuzunguruko yoroheje kandi igerwaho. Igikorwa cyacyo nyamukuru ni ukugenzura imiyoboro ihanitse hamwe n’umuvuduko muke, bigatuma ikorwa mu buryo bwikora, kurinda umutekano, hamwe no guhinduranya imirongo.
