Ni ubuhe bwoko bwa PCB bushobora kwihanganira 100 A?

Ubusanzwe igishushanyo mbonera cya PCB ntikirenza 10 A, cyangwa na 5 A. Cyane cyane murugo no mubikoresho bya elegitoroniki byabaguzi, mubisanzwe amashanyarazi ahoraho kuri PCB ntarenza 2 A

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.

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

Uburambe bwa PCB ni: kongera umubyimba wumuringa, kwagura diameter, no kunoza ubushyuhe bwa PCB birashobora kongera ubushobozi bwo gutwara PCB.

Niba rero nshaka gukora umuyoboro wa 100 A, nshobora guhitamo umubyimba wumuringa wa 4 OZ, ugashyiraho ubugari bwumurongo kuri mm 15, ibimenyetso byimpande zombi, hanyuma nkongeramo ubushyuhe kugirango ugabanye ubushyuhe bwa PCB no kunoza ituze.

Uburyo bwa kabiri: terminal

Usibye insinga kuri PCB, inyandiko zoherejwe zirashobora no gukoreshwa.

Kosora ama terefone menshi ashobora kwihanganira 100 A kuri PCB cyangwa igicuruzwa cyibicuruzwa, nkibiti byo hejuru byubutaka, PCB ya terefone, inkingi z'umuringa, nibindi.Muri ubu buryo, imigezi minini irashobora kunyura mu nsinga.

Uburyo bwa gatatu: umuringa wumuringa

Ndetse utubari twumuringa turashobora gutegurwa.Ni akamenyero gasanzwe mu nganda gukoresha utubari twumuringa kugirango utware imigezi minini.Kurugero, transformateur, seriveri yububiko nizindi porogaramu zikoresha umuringa wumuringa kugirango utware imigezi minini.

Uburyo bwa 4: Inzira idasanzwe

Mubyongeyeho, hariho izindi progaramu zidasanzwe za PCB, kandi ntushobora kubona uruganda mubushinwa.Infineon ifite ubwoko bwa PCB ifite igishushanyo mbonera cya 3.Hejuru no hepfo ibice byerekana ibimenyetso, naho igice cyo hagati ni umuringa ufite umubyimba wa mm 1.5, ukoreshwa muburyo bwo gutegura ingufu.Ubu bwoko bwa PCB burashobora kuba buto mubunini.Temba hejuru ya 100 A.
