Tus Qauv PCTs ib txwm tam sim no tsis pub tshaj 10 a, lossis txawm tias 5 A. tshwj xeeb hauv tsev neeg thiab cov neeg siv khoom lag luam nyob rau ntawm PCB tsis pub tshaj 2 a
Txoj kev 1: Layout ntawm PCB
Txhawm rau txiav txim siab tshaj-tam sim no muaj peev xwm ntawm PCB, peb thawj zaug pib nrog PCB cov qauv. Siv ob-txheej pcb ua piv txwv. Qhov no zoo ntawm Circuit Court board feem ntau muaj peb txheej txheej txheej txheem: tawv nqaij tooj liab, phaj, thiab tawv nqaij tawv. Cov tawv nqaij tooj liab yog txoj hauv kev uas tam sim no thiab teeb liab hauv PCB pass. Raws li kev paub ntawm Tsev Kawm Ntawv Middle Bysics, peb tuaj yeem paub tias qhov kev tawm tsam ntawm ib qho khoom yog cuam tshuam nrog cov khoom siv, hla kev hla ntawm thaj chaw, thiab ntev. Txij li peb cov tam sim no sau ntawm cov tawv nqaij tooj liab, qhov tiv taus yog tsau. Qhov chaw hla kev hla tebchaws tuaj yeem raug suav tias yog qhov tuab ntawm cov tawv nqaij tooj liab, uas yog tooj liab tuab hauv cov PCB ua. Feem ntau tooj liab tuab yog qhia tawm hauv OZ, tus tooj liab tuab ntawm 1 oz yog 35 um, 2 oz yog 70 teev, thiab lwm yam. Tom qab ntawd nws tuaj yeem yooj yim xaus lus tias thaum muaj qhov loj tam sim no yog yuav tsum tau dhau ntawm PCB, cov xaim yuav tsum luv thiab tuab, thiab cov ntawv sau zoo dua.
Hauv kev siv tshuab, tsis muaj tus qauv nruj rau qhov ntev ntawm cov xaim. Feem ntau siv hauv kev tsim khoom: tooj liab thickness / kub sawv / cov ntsuas phoo no los ntsuas qhov peev xwm ntawm PCB.
PCB Kev Siv Hluav Taws Xob yog: nce lub tooj liab tuab, thiab txhim kho cov pa xaim hlau, thiab txhim kho cov pa xaim hluav taws xob ntawm tus PCB tuaj yeem txhim kho qhov muaj peev xwm ntawm tus PCB.
Yog li yog tias kuv xav khiav ib qho tam sim no 100 a, Kuv tuaj yeem xaiv lub tooj liab tuab ntawm 4 mm, muab ob npaug rau cov cua sov kom txo tau qhov kev ncua tshav kub kom txo qis ntawm PCB thiab txhim kho kev ruaj khov.

Txoj kev ob: davhlau ya nyob twg
Ntxiv nrog rau kev xaim ntawm PCB, cov ntawv xov hluav taws xob kuj tseem siv tau.
Txhim kho ob peb lub terminals uas tuaj yeem tiv taus 100 lub hnab ntim khoom, xws li cov ntaub qhwv khoom, thiab lwm yam. Nyob rau hauv txoj kev no, cov dej ntws loj tuaj yeem hla cov xov hlau.
03
Txoj kev Peb: Cov Nyiaj Tooj Liab tooj liab Busbar
Txawm tias tooj liab tuav tuaj yeem ua tau customized. Nws yog ib qho kev coj ua hauv kev lag luam los siv cov tooj liab tuav kom nqa cov dej loj. Piv txwv li, transformers, neeg rau zaub mov xwm thiab lwm yam kev siv siv cov tooj liab tuav los nqa cov dej khov loj.

Txoj kev 4: Cov Txheej Txheem Tshwj Xeeb
Ib qho ntxiv, muaj qee cov txheej txheem tshwj xeeb pcb, thiab koj yuav tsis tuaj yeem nrhiav cov chaw tsim khoom hauv Suav teb. Infineon muaj hom PCB nrog rau 3-txheej tooj liab txheej txheej qauv. Sab saum toj thiab hauv qab yog cov teeb liab txheej txheem hluav taws xob, thiab txheej nruab nrab yog cov txheej tooj liab nrog cov tuab ntawm 1.5 mm, uas tau siv tshwj xeeb los npaj lub zog. Hom PCB no yooj yim me me. Ntws saum 100 A.
