Uyilo oluqhelekileyo lwe-PCB lungadluli kwi-10 A, okanye 5 A. Kumzila wombane, idla ngokubasebenza ngokuqhubekayo okwangoku kwi-PCB ayidluli 2 a
Indlela yoku-1: Ubume kwi-PCB
Ukufumanisa amandla angaphezulu kwe-PCB, siqala ukuqala ngesakhiwo sePCB. Thatha i-pcb ye-windows kunye nomzekelo. Olu hlobo lwebhodi yesekethe luhlala lunemigangatho emithathu ye-3: ulusu lobhedu, iplate, kunye nolusu lobhedu. Ulusu lobhedu yindlela apho ikhoyo ngoku kwaye isayini kwi-PCB Pass. Ngokutsho kolwazi lwesikolo esiphakathi, siyakwazi ukuba ukuxhathisa kwento inxulumene nezinto ezibonakalayo, indawo enqamlezileyo, kunye nobude. Ukusukela ukuba ukuqhuba kwethu kulusu lobhedu, ukuxhathisa kuyalungiswa. Indawo enqamlezileyo yecandelo inokuthathwa njengobubukhulu bolusu lobhedu, obu bubutyebi bukabhedu kwiinketho zokulungiswa kwe-PCB. Ngokwesiqhelo ubukhulu be-copper ubonakalisiwe kwi-OZ, ubukhulu becala le-1 oz yi-35 m, 2 oz yi-70 ye, njalo njalo. Emva koko inokugqitywa ngokulula ukuba xa i-PCB idluliselwe kwi-PCB, i-wiring kufuneka ibe mfutshane kwaye ibe mfutshane, kwaye inomkhuhlane wobhedu lwe-PCB, engcono.
Kubunjineli bokwenyani, akukho mgangatho ongqongqo wobude be-wiring. Ihlala isetyenziswa kubunjineli: ubukhulu becala / ubushushu obunyukayo / ububanzi be-wire, ezi zikhombisi zintathu zokulinganisa ukuthutha iBhodi yePCB.
Amava e-PCB Wiring ngu: Ukonyusa ubukhulu bobhedu, ukwandisa ububanzi be-wire, kunye nokuphucula ukungavisisani kobushushu kwe-PCB kunokuphucula amandla okuthwasa i-PCB.
Ke ukuba ndifuna ukuqhuba ubukhulu be-100 ka-A, ndingakhetha ubungqingqwa be-4 oz, bamisela umkhondo obenziweyo ukuya kwi-15 mm, kwaye bongeze isinki esisikiweyo sokunciphisa ubushushu be-PCB kunye nokuphucula uzinzo.

Indlela yesibini: Isiphelo sendlela
Ukongeza kwi-wiring kwi-PCB, izithuba ze-wiring zinokusetyenziswa.
Lungisa iindawo ezininzi ezinokukukhathalela i-100 A kwi-PCB okanye iqokobhe lemveliso, i-PHBS, iikholamu zePCB, iikholamu zobhedu, njl. Ngale ndlela, imijikelezo emikhulu inokudlula kwiingcingo.
03
Indlela yesithathu: isiko lobhedu
Nokuba imivalo yobhedu inokwenziwa ngokwezifiso. Yinto eqhelekileyo kumzi-mveliso ukuze usebenzise imivalo yobhedu ukuba ithwale imisinga enkulu. Umzekelo, abaguquli, iikhabhathi zeseva kunye nezinye iinkqubo zisebenzisa imivalo yobhedu ukuba zithwale imisinga enkulu.

Indlela 4: Inkqubo ekhethekileyo
Ukongeza, zikho iinkqubo ezizodwa zePCB, kwaye awukwazi ukufumana uMvelisi e-China. I-infineson inohlobo lwe-PCB ene-3-ferper copper yoshicilelo. Iingqimba eziphezulu nezingaphantsi zezantsi zizimboli zomqondiso, kwaye umyinge ophakathi luphawu lobhedu olunobunzima be-1.5 mm, esetyenziselwa ngokukodwa ukucwangcisa amandla. Olu hlobo lwe-PCB lunokuba mncinci ngobukhulu. Ukuhamba ngaphezulu kwe-100 A.
