PCBs hauv cov khoom lag luam yog ib feem tseem ceeb ntawm cov khoom siv hluav taws xob niaj hnub no. Copper thickness yog ib qho tseem ceeb heev hauv cov txheej txheem tsim PCB. Qhov tseeb tooj liab tuab tuaj yeem ua kom zoo thiab ua haujlwm ntawm lub rooj tsav xwm Circuit Court, thiab tseem cuam tshuam rau kev ntseeg tau thiab ruaj khov ntawm cov khoom siv hluav taws xob.

Feem ntau, peb cov tuab tuab yog 17.5um (0.5oz), 35um (1oz), 70um (2oz)

Copper thickness txiav txim qhov hluav taws xob conductivity ntawm Circuit Court board. Tooj liab yog cov khoom siv hluav taws xob zoo heev, thiab nws cov tuab ncaj qha cuam tshuam rau cov nyhuv conductive ntawm lub rooj tsavxwm. Yog tias cov txheej tooj liab nyias dhau lawm, cov khoom siv hluav taws xob tuaj yeem txo qis, ua rau cov teeb liab kis tau los ntawm kev txo qis lossis tsis muaj zog tam sim no. Yog hais tias cov txheej tooj liab yog tuab heev, txawm tias cov conductivity yuav zoo heev, nws yuav ua rau kom tus nqi thiab qhov hnyav ntawm lub rooj tsav xwm Circuit Court. Yog tias txheej tooj liab yog tuab heev, nws yuav yooj yim ua rau cov kua nplaum loj heev, thiab yog tias cov txheej txheem dielectric nyias dhau lawm, qhov nyuaj ntawm kev ua haujlwm hauv Circuit Court yuav nce. Yog li ntawd, 2oz tooj liab thickness feem ntau tsis pom zoo. Hauv kev tsim PCB, qhov tsim nyog tooj liab tuab yuav tsum raug xaiv raws li cov qauv tsim thiab kev siv tiag tiag ntawm lub rooj tsav xwm Circuit Court kom ua tiav cov txiaj ntsig zoo tshaj plaws.

Thib ob, tooj liab thickness kuj muaj qhov cuam tshuam tseem ceeb ntawm kev ua haujlwm kub ntawm lub rooj tsavxwm. Raws li cov khoom siv hluav taws xob niaj hnub no dhau los ua ntau dua thiab muaj zog, muaj cua sov ntau dua thaum lawv ua haujlwm. Kev ua haujlwm zoo thaum tshav kub kub tuaj yeem ua kom ntseeg tau tias qhov kub ntawm cov khoom siv hluav taws xob tswj tau nyob rau hauv qhov chaw nyab xeeb thaum ua haujlwm. Cov txheej tooj liab ua haujlwm raws li cov txheej txheem thermal conductive ntawm lub rooj tsav xwm hauv Circuit Court, thiab nws cov thickness txiav txim siab cov nyhuv thermal dissipation. Yog tias cov txheej tooj liab nyias dhau lawm, cov cua sov yuav tsis ua thiab dissipated zoo, ua rau muaj kev pheej hmoo ntawm cov khoom overheating.

Yog li ntawd, tooj liab thickness ntawm PCB tsis tuaj yeem nyias dhau. Thaum lub sij hawm tsim PCB txheej txheem, peb kuj tuaj yeem nteg tooj liab nyob rau hauv qhov chaw dawb paug los pab lub tshav kub dissipation ntawm PCB board. Hauv kev tsim PCB, xaiv qhov tsim nyog tooj liab tuab tuaj yeem ua kom ntseeg tau tias lub rooj tsav xwm hauv Circuit Court muaj cov cua sov zoo. kev ua tau zoo los xyuas kom muaj kev nyab xeeb ntawm cov khoom siv hluav taws xob.

Tsis tas li ntawd, tooj liab thickness kuj muaj qhov cuam tshuam tseem ceeb ntawm kev ntseeg siab thiab kev ruaj ntseg ntawm lub rooj tsav xwm Circuit Court. Cov txheej tooj liab tsis tsuas yog ua haujlwm raws li cov txheej txheem hluav taws xob thiab thermally conductive, tab sis kuj tseem ua haujlwm raws li kev txhawb nqa thiab kev sib txuas txheej rau lub rooj tsav xwm hauv Circuit Court. Lub thickness ntawm tooj liab zoo tuaj yeem muab cov khoom siv dag zog txaus los tiv thaiv lub rooj tsav xwm Circuit Court los ntawm kev khoov, tawg lossis qhib thaum siv. Nyob rau tib lub sijhawm, qhov tsim nyog tooj liab tuab tuaj yeem ua kom cov vuam zoo ntawm lub rooj tsav xwm hauv Circuit Court thiab lwm yam khoom thiab txo qhov kev pheej hmoo ntawm vuam tsis xws luag thiab tsis ua haujlwm. Yog li ntawd, hauv PCB kev tsim khoom, xaiv qhov tsim nyog tooj liab tuab tuaj yeem txhim kho kev ntseeg tau thiab ruaj khov ntawm lub rooj tsav xwm hauv Circuit Court thiab txuas ntxiv lub neej kev pab cuam ntawm cov khoom siv hluav taws xob.

Txhawm rau ua kom tiav, qhov tseem ceeb ntawm tooj liab thickness hauv PCB tsim tsis tuaj yeem tsis quav ntsej. Qhov tseeb tooj liab tuab tuaj yeem ua kom muaj hluav taws xob conductivity, kev ua haujlwm kub dissipation, kev ntseeg tau thiab ruaj khov ntawm lub rooj tsav xwm hauv Circuit Court.

Hauv cov txheej txheem tsim khoom tiag tiag, nws yog qhov tsim nyog los xaiv qhov tsim nyog tooj liab tuab raws li cov khoom siv hluav taws xob tsim hluav taws xob, cov kev xav tau ntawm kev ua haujlwm, thiab kev tswj tus nqi kom ntseeg tau tias qhov zoo thiab kev ua haujlwm ntawm cov khoom siv hluav taws xob. Tsuas yog nyob rau hauv txoj kev no tuaj yeem ua tau zoo PCBs kom tau raws li qhov kev ua tau zoo thiab kev ntseeg siab ntawm cov khoom siv hluav taws xob niaj hnub no.
