Ibishushanyo mbonera bya PCB bisanzwe ntibirenza 10A, cyane cyane murugo rwa elegitoroniki n’abaguzi, mubisanzwe imiyoboro ikomeza kuri PCB ntabwo irenga 2A.

Nyamara, ibicuruzwa bimwe byabugenewe gukoresha amashanyarazi, kandi imiyoboro ikomeza irashobora kugera kuri 80A.Urebye akanya ako kanya hanyuma ugasiga intera kuri sisitemu yose, umuyoboro uhoraho wamashanyarazi ugomba kuba ushobora kwihanganira ibirenga 100A.

Noneho ikibazo niki, ni ubuhe bwoko bwa PCB bushobora kwihanganira umuyoboro wa 100A?

Uburyo 1: Imiterere kuri PCB

Kugirango tumenye ubushobozi burenze-bwa PCB, tubanza gutangirana na PCB imiterere.Fata urugero rwa PCB ebyiri.Ubu bwoko bwumuzunguruko busanzwe bufite ibice bitatu: uruhu rwumuringa, isahani, nuruhu rwumuringa.Uruhu rwumuringa ninzira inyuramo nibimenyetso muri PCB.

Dukurikije ubumenyi bwa fiziki yo mumashuri yisumbuye, turashobora kumenya ko kurwanya ikintu bifitanye isano nibikoresho, agace kambukiranya, n'uburebure.Kubera ko ikigezweho kigenda kuruhu rwumuringa, kurwanywa birakosowe.Agace kambukiranya igice gashobora gufatwa nkubunini bwuruhu rwumuringa, aribwo uburebure bwumuringa muburyo bwo gutunganya PCB.

Mubisanzwe uburebure bwumuringa bugaragarira muri OZ, uburebure bwumuringa bwa 1 OZ ni 35 um, 2 OZ ni 70 um, nibindi.Noneho birashobora kwemezwa byoroshye ko mugihe umuyoboro munini ugomba kunyuzwa kuri PCB, insinga zigomba kuba ngufi kandi nini, kandi umubyimba mwinshi wumuringa wa PCB, nibyiza.

Mubyukuri, mubuhanga, ntamahame akomeye yuburebure bwinsinga.Mubisanzwe bikoreshwa mubuhanga: uburebure bwumuringa / kuzamuka kwubushyuhe / diameter ya wire, ibi bipimo bitatu kugirango bipime ubushobozi bwo gutwara ubu bubiko bwa PCB.
