PCByog ib qho tseem ceeb ntawm cov khoom siv hluav taws xob, thiab cov txheej txheem tooj liab yog qhov tseem ceeb ntawm PCB. Lub thickness ntawm cov ntawv ci tooj liab muaj qhov cuam tshuam loj rau kev ua haujlwm thiab qhov zoo ntawm PCB.
1. Phaj thickness
Lub thickness ntawm lub rooj tsavxwm yog ib qho tseem ceeb hauv kev txiav txim siab lub thickness ntawm tooj liab foil txheej. Feem ntau, lub thicker lub PCB board, lub thickness ntawm tooj liab ntawv ci txheej kuj yuav nce raws li. Cov phaj tuab tuaj yeem nqa cov dej ntws loj thiab lub zog, thiab tau siv dav hauv cov khoom siv hluav taws xob siab.
2. Thaum tshav kub kub dissipation yuav tsum
Copper foil txheej hauv PCB muaj cov thermal conductivity zoo, uas tuaj yeem pab ua kom sov. Nyob rau hauv daim ntawv thov scenarios nrog high tshav kub dissipation yuav tsum, xaiv ib tug thicker tooj liab ntawv ci txheej yuav ua tau kom sov dissipation efficiency.
3. Kev thov tam sim no
Lub thickness ntawm tooj liab ntawv ci txheej kuj yog ze ze rau qhov kev thov tam sim no. Yog hais tias qhov loj tam sim no yuav tsum tau ua nyob rau hauv Circuit Court, ib tug thicker tooj liab ntawv ci txheej yuav tsum tau xaiv kom muaj zog conductivity thiab tsis txhob overheating.
4. Kab complexity
Lub thickness ntawm cov ntawv ci tooj liab txheej ntawm PCB yuav tsum coj mus rau hauv tus account lub complexity ntawm Circuit Court. PCBs nrog high circuit complexity yuav tsum thicker copper foil txheej los xyuas kom meej cov teeb liab kis tau tus mob thiab kev cia siab ntawm Circuit Court.
5. PCB txheej
PCB tuaj yeem tsim los ntawm cov txheej txheem sib txawv xws li ib txheej txheej, ob txheej txheej, ntau txheej, thiab lwm yam. Feem ntau, ntau txheej PCBs yuav tsum muaj cov txheej txheem tooj liab tuab kom nqa tau ntau dua tam sim no thiab cov teeb liab kis tau tus mob.
