Mapangidwe anthawi zonse a PCB sapitilira 10A, makamaka zamagetsi am'nyumba ndi ogula, nthawi zambiri zomwe zikuchitika pa PCB sizidutsa 2A.

Komabe, zinthu zina zimapangidwira mawaya amagetsi, ndipo zomwe zikuchitika nthawi zonse zimatha kufika pafupifupi 80A.Poganizira zomwe zikuchitika nthawi yomweyo ndikusiya malire a dongosolo lonse, mphamvu yowonjezera yamagetsi yamagetsi iyenera kupirira kuposa 100A.

Ndiye funso ndilakuti, ndi mtundu wanji wa PCB womwe ungapirire ndi 100A yamakono?

Njira 1: Mapangidwe a PCB

Kuti tidziwe momwe PCB ilili, timayamba ndi mawonekedwe a PCB.Tengani pawiri wosanjikiza PCB monga chitsanzo.Mtundu uwu wa board board nthawi zambiri umakhala ndi magawo atatu: khungu lamkuwa, mbale, ndi khungu lamkuwa.Khungu lamkuwa ndi njira yomwe magetsi ndi chizindikiro mu PCB amadutsa.

Malingana ndi chidziwitso cha sayansi ya sukulu ya pulayimale, tikhoza kudziwa kuti kukana kwa chinthu kumakhudzana ndi zinthu, malo ozungulira, ndi kutalika.Popeza kuti panopa timayendetsa pakhungu lamkuwa, resistivity imakhazikika.Dera lamtanda limatha kuwonedwa ngati makulidwe a khungu lamkuwa, lomwe ndi makulidwe amkuwa muzosankha za PCB.

Nthawi zambiri makulidwe amkuwa amawonetsedwa mu OZ, makulidwe amkuwa a 1 OZ ndi 35 um, 2 OZ ndi 70 um, ndi zina zotero.Ndiye zikhoza kuganiziridwa mosavuta kuti pamene mphamvu yaikulu iyenera kuperekedwa pa PCB, waya ayenera kukhala waufupi komanso wandiweyani, ndipo makulidwe a mkuwa a PCB, ndibwino.

Kwenikweni, mu engineering, palibe muyezo wokhazikika wautali wa waya.Nthawi zambiri ntchito uinjiniya: mkuwa makulidwe / kutentha kukwera / waya awiri, zizindikiro zitatuzi kuyeza panopa kunyamula mphamvu ya bolodi PCB.
