Hauv PCB (luam tawm cov boardracuit board) kev tsim qauv, kev xaiv tooj ntawm tooj liab qhov yog qhov tseem ceeb cuam tshuam rau kev ua tau zoo thiab kev ntseeg tau ntawm Circuit Court Board.
Ntawm no yog cov laj thawj yog vim li cas qee cov laug cam xaiv xaiv siv tus tooj liab tuab li:
1. Tam sim no nqa cov khoom lag luam tuab ntau dua tuaj yeem txhim kho cov laug cam ntawm PCB, tshwj xeeb yog nyob rau hauv kev loj hlob tam sim no, kom muaj kev phom sij thiab kev ntseeg tau ntawm Circuit Txwv.
2. Cua sov dissipation actikea siab dua cov laug cam ntau dua tuaj yeem ua kom cua sov thiab muaj peev xwm muaj kev tiv thaiv cua sov thiab cov khoom siv zoo dua.
3. Cov paib muaj zog dua tooj liab lub qhov hluav taws xob thiab kev kis tus kab mob thiab kev sib kis tau zoo dua qub, uas tuaj yeem zoo dua ua kom tau teeb liab qhov tseeb thiab kev ruaj ntseg.
4. Vuam Kev Kawm
Ib qho tuab dua tooj liab tuab tuaj yeem txhim kho kev ua tau zoo ntawm PCB cov laug cam, tshwj xeeb tshaj yog hauv cov pob qij txha ua kom zoo dua qub, ua kom muaj kev sib txuas nrog, kom muaj kev sib txuas thiab smorting.
5. Cov neeg siv zog tsis tsim nyog tooj liab lub zog tuaj yeem muab cov tshuab hluav taws xob kom tiv thaiv tau lub zog Circuit Court Board los ntawm khoov, tawg, lossis solding thaum siv. Meanwhile, ib qho tsim nyog tooj liab hlau tuaj yeem ua kom cov vuam zoo ntawm cov Cirtral Board thiab lwm cov kev pheej hmoo ntawm vuam tsis xws luag thiab ua tsis tiav.
6. Daim ntawv thov yuav tsum tau ua kab uas xav tau siab tam sim no, tus tooj liab tuab yuav tsum yog widened thiab tsa. Yog tias widened, nws yuav nyob thaj chaw tiaj tiaj, ua rau PCB loj kom nce, ua tus nqi thiab ntim tsis zoo li qub. Los ntawm kev siv tooj liab kom nce qhov siab, cov teeb meem saum toj no tuaj yeem zam tau.
7. Cov ntawv thov siab tam sim no
Tuab tooj liab pcb (xws li 5oz tooj) yog tsim nyog rau cov tshuab lossis khoom siv nrog cov peev txheej siab tam sim no, xws li cov tshuab hnyav siv hauv kev lag luam. Lawv tuaj yeem ua haujlwm ib txwm muaj nyob ntawm qib siab thiab lawv qib kev ua tau yuav tsis txo qis. Tsis tas li ntawd, cov yeeb yam no ua rau nws haum rau txhua lub zog siv hluav taws xob thiab tshuab.
