Gudanar da jirgin wutar lantarki yana taka muhimmiyar rawa a cikin ƙirar PCB. A cikin cikakken aikin ƙira, sarrafa wutar lantarki na iya ƙayyade yawan nasarar nasarar 30% – 50% na aikin. A wannan karon, za mu gabatar da muhimman abubuwan da yakamata a yi la’akari da su a cikin sarrafa jirgin sama mai ƙarfi a cikin ƙirar PCB.
1. Lokacin yin aikin sarrafa wutar lantarki, abin da ya kamata a fara la’akari da shi shine ƙarfin ɗaukar nauyinsa na yanzu, gami da ɓangarori biyu.
(a) Ko faɗin layin wutar ko faɗin takardar jan ƙarfe ya wadatar. Don la’akari da faɗin layin wutar, da farko ku fahimci kaurin jan ƙarfe na Layer inda ake sarrafa siginar wutar. A ƙarƙashin tsari na al’ada, kaurin jan ƙarfe na saman Layer (saman / ƙasa Layer) na PCB shine 1oz (35um), kuma kaurin tagulla na cikin ciki zai zama 1oz ko 0.5oz gwargwadon ainihin yanayin. Domin kauri 1oz na jan ƙarfe, a ƙarƙashin yanayin al’ada, 20MIL na iya ɗaukar kusan 1A na yanzu; 0.5oz jan kauri. A ƙarƙashin yanayin al’ada, 40mil na iya ɗaukar kusan 1A na yanzu.
(b) Ko girman da adadin ramukan sun hadu da ƙarfin samar da wutar lantarki a halin yanzu yayin canjin Layer. Na farko, fahimtar ƙarfin kwarara guda ɗaya ta rami. A ƙarƙashin yanayi na al’ada, hauhawar zafin jiki shine digiri 10, wanda za’a iya komawa zuwa teburin da ke ƙasa.
“Teburin kwatancen ta ta diamita da ƙarfin kwararar wutar” teburin kwatancen ta ta diamita da ƙarfin kwararar wutar
Ana iya gani daga teburin da ke sama cewa madaidaicin mil 10 na iya ɗaukar 1A na yanzu. Sabili da haka, a cikin ƙira, idan ƙarfin wutan lantarki yana 2A na yanzu, aƙalla vias 2 yakamata a haƙa lokacin amfani da 10mil vias don maye gurbin rami. Gabaɗaya, lokacin ƙira, zamuyi la’akari da haƙa ƙarin ramuka akan tashar wutar lantarki don kiyaye ɗan gefe.
2. Abu na biyu, ya kamata a duba hanyar ikon. Musamman, ya kamata a yi la’akari da bangarorin biyu masu zuwa.
(a) Hanyar wutar yakamata ta zama takaitacciya. Idan ya yi tsayi da yawa, raguwar ƙarfin wutan lantarki zai yi tsanani. Rage ƙarfin lantarki mai yawa zai haifar da gazawar aikin.
(b) Rarraba wutar lantarki na samar da wutar lantarki za a kiyaye shi akai -akai kamar yadda zai yiwu, kuma ba a yarda da tsiri mai tsini da raunin dumbbell ba.
