PCBs hauv cov khoom sib tshooj yog qhov tseem ceeb ntawm cov khoom siv hluav taws xob niaj hnub no. Tooj liab tuab yog qhov tseem ceeb heev hauv PCB kev ua tiav. Tus tooj liab tuab tuaj yeem ua kom muaj kev ua tau zoo thiab ua tau zoo ntawm Circuit Coud Board, thiab tseem cuam tshuam txog kev ntseeg tau thiab muaj kev ruaj ntseg ntawm cov khoom siv hluav taws xob.
Feem ntau, peb cov tooj liab tuab yog 17.5um (0.5oz), 35um (1oz), 70um (2oz)
Tooj liab tuab txiav txim siab hluav taws xob hluav taws xob ntawm cov Circuitity Board. Tooj liab yog cov khoom siv tau zoo tshaj plaws, thiab nws cov thickness ncaj qha cuam tshuam cov kev coj ua ntawm Circuit Court Board. Yog tias cov txheej tooj liab kuj dhau heev, cov khoom ua tau zoo yuav txo qis, ua rau cov paib kev sib tw kis lossis qhov tsis muaj peev xwm tam sim no. Yog tias txheej tooj liab tooj tuab heev, txawm hais tias qhov kev coj ua yuav zoo heev, nws yuav ua rau tus nqi thiab qhov hnyav ntawm Circuit Courruit Board. Yog tias cov tawv tooj liab tawv tawv tawv tawv tawv tawv, nws yuav ua rau cov kua nplaum loj, thiab yog tias cov txheej dielectric yog cov tawv dhau lawm, qhov nyuaj ntawm Circuit Court kev yuav nce ntxiv. Yog li ntawd, 2oz tooj liab tuab yog feem ntau tsis pom zoo. Hauv PCB tsim, cov tooj liab tooj liab tsim nyog yuav tsum tau xaiv raws cov qauv yuav tsum muaj thiab cov ntawv thov Circuit Court kom ua tiav cov nyhuv zoo tshaj plaws.
Thib ob, tooj liab tuab kuj muaj qhov cuam tshuam tseem ceeb rau kev ua haujlwm kub dissipation ntawm lub Circuit Court Board. Raws li niaj hnub hluav taws xob ua haujlwm tau ntau dua thiab muaj zog ntau dua, ntau dua thiab ntau dua kub kub yog tsim thaum lawv ua haujlwm. Kev kub kub sov disspation kev ua tau zoo tuaj yeem paub tseeb tias qhov kub ntawm cov hluav taws xob sib xyaw ua haujlwm hauv kev ua haujlwm. Tus tooj liab txheej ua haujlwm ua cov thermal conductive txheej ntawm Cirtral Board, thiab nws cov tuab txiav txim siab cov nyhuv kub dissipation nyhuv. Yog hais tias lub tooj liab txheej yuag dhau, tshav kub tsis tuaj yeem ua thiab dissipated zoo, ua kom muaj kev pheej hmoo ntau ntawm cov khoom siv overheating.
Yog li ntawd, tooj liab tuab ntawm tus PCB tsis tuaj yeem yuag. Thaum lub sijhawm PCB tsim, peb tuaj yeem tso tooj liab nyob hauv thaj chaw dawb paug los pab cov tshav kub dissipation of PCB board. Hauv PCB tsim, xaiv cov tooj liab tickness tsim nyog tuaj yeem paub tseeb tias Circuit Court Board tau ua kom sov dissipation. Kev ua tau zoo kom ua tau kev nyab xeeb ntawm cov hluav taws xob sib xyaw.
Ib qho ntxiv, Copper Thickness tseem muaj qhov cuam tshuam tseem ceeb rau kev ntseeg tau thiab muaj kev ruaj ntseg ntawm Circuit Court Board. Cov txheej tooj liab tsis tsuas yog siv hluav taws xob thiab siv hluav taws xob, tab sis kuj ua haujlwm ua kev txhawb nqa thiab kev sib txuas txheej rau cov Circuit Court Board. Lub zog tooj liab kom zoo tuaj yeem muab cov tshuab ua kom muaj zog kom tiv thaiv cov Circuit Court Board los ntawm khoov, tawg lossis qhib thaum siv. Nyob rau tib lub sijhawm, cov tooj liab tooj tau tsim nyog tuaj yeem ua kom cov vuam muag vuam thiab lwm cov kev pheej hmoo thiab txo qhov kev pheej hmoo ntawm vuam tsis zoo thiab tsis ua haujlwm. Yog li ntawd, hauv PCB raug tsim, xaiv cov tooj liab tooj liab tuaj yeem txhim kho kev ntseeg tau thiab muaj kev ruaj ntseg ntawm cov khoom pabcuam hluav taws xob.
Txhawm rau suav, qhov tseem ceeb ntawm tooj liab tuab hauv PCB kev tsim khoom tsis tuaj yeem tsis quav ntsej. Tus tooj liab tuab tuaj yeem ua kom cov hluav taws xob conduction, tshav kub dissipation kev ua tau zoo, kev cia siab thiab muaj kev ruaj ntseg ntawm Circuit Court Board.
Hauv cov txheej txheem tsim kev tsim khoom, nws yog ib qho tsim nyog los xaiv cov tooj liab uas tsim nyog raws li cov kev tsim nyog, thiab tswj hwm cov khoom siv hluav taws xob. Tsuas yog nyob rau hauv txoj kev no tuaj yeem zoo pcbs tau tsim tawm kom tau raws li kev ua tau zoo thiab siab ntseeg tau cov khoom siv hluav taws xob niaj hnub.
