Kupanga kwa PCB kwanthawi zonse sikupitilira 10A, makamaka pakompyuta ndi makanema ogulitsa, nthawi zambiri amapitilirabe pa PCB sapitirira 2a.

Komabe, zinthu zina zimapangidwira kuti zikhale zowomba zamphamvu, ndipo zomwe zikupitilira zitha kufikira pafupifupi 80a. Poganizira nthawi yomweyo komanso kusiya malire a kachitidwe kalikonse, komwe kumapitilira muyeso kuyenera kupirira zoposa 100A.

Ndiye funso ndi loti, Kodi ndi mtundu wanji wa PCB yomwe ingapirire pakali pano ya 100a?

Njira 1: Masankhidwe pa PCB

Kuti mudziwe zambiri za PCB, timayamba ndi kapangidwe ka PCB. Tengani PCB yowonjezera kawiri. Bolo lamtunduwu nthawi zambiri limakhala ndi kapangidwe katatu: khungu lanu, ndi khungu lamkuwa. Khungu lamkuwa ndi njira yomwe ilipo kale ndi chizindikiro mu PCB idadutsa.

Malinga ndi chidziwitso cha sayansi yapakati yapakati, titha kudziwa kuti kukana kwa chinthu kumagwirizana ndi nkhaniyo, malo okhala, ndi kutalika. Popeza zomwe timachita pakhungu lamkuwa, kusamvana kuli kokhazikika. Malo okhala pamtanda amatha kuwonedwa ngati makulidwe a khungu lamkuwa, lomwe ndi makulidwe amkuwa mu pCB process zosankha.

Nthawi zambiri makulidwe amkuwa amafotokozedwa ku OZ, makulidwe amkuwa a 1 oz ndi 35 um, 2 oz ndi 70 um, ndi zina zambiri. Kenako zitha kutsimikiziridwa mosavuta kuti pamene zikuluzikulu zikaperekedwa pa PCB, zingwe ziyenera kukhala zazifupi komanso zandiweyani, komanso zokulirapo, ndi makulidwe amkuwa cha PCB, yabwinoko.

Kwenikweni, mu ukadaulo, palibe muyezo wokhwima kwambiri. Nthawi zambiri amagwiritsidwa ntchito mu ukadaulo: Mkulu wa mkuwa / kutentha - mai wala, zisonyezo zitatuzi kuti muyeze luso la PCB bolodi la PCB.
