Feem ntau, tooj liab thickness ntawm tus qauv PCB yog 1oz rau 3oz. Thick-copper PCBs lossis hnyav-tooj ​​liab PCBs yog hom PCBs uas qhov hnyav tooj liab tiav yog ntau tshaj 4oz (140μm).Cov tooj liab tuab tso cai rau PCB loj-cross-sections rau cov loads siab tam sim no thiab txhawb kom muaj cua sov dissipation. Cov qauv tsim feem ntau yog multilayer lossis ob sab. Nrog rau PCB thev naus laus zis no nws kuj tseem tuaj yeem ua ke cov txheej txheem zoo ntawm cov txheej txheem txheej txheej thiab cov txheej tooj liab tuab hauv cov txheej txheej sab hauv.
Cov tuab-tooj ​​liab PCB belongs rau ib hom tshwj xeeb ntawm PCB. nws cov khoom siv hluav taws xob, cov khoom siv substrate, cov txheej txheem ntau lawm, daim ntawv thov teb yog txawv ntawm cov qauv PCBs. Lub plating ntawm tuab tooj liab circuits tso cai rau PCB cov tuam txhab ua kom cov tooj liab hnyav nyob rau ntawm cov phab ntsa thiab plated qhov, uas tuaj yeem txo cov lej thiab cov hneev taw. Thick-tooj ​​liab plating integrates high-tam sim no thiab tswj circuits, ua high-density nrog yooj yim board qauv yuav ua tau tiav.
Kev tsim kho ntawm cov
1.Increase tam sim no muaj peev xwm zoo heev
2.Higher endurance rau thermal strains
3.Zoo dua tshav kub dissipation
4.Increase lub mechanical zog ntawm connectors thiab PTH qhov
5. Txo cov khoom loj
Kev siv cov tuab-tooj ​​liab PCBs
Nrog rau kev nce ntawm cov khoom siv hluav taws xob ntau, qhov kev thov rau tuab-tooj ​​liab PCBs tau nce ntau heev. Niaj hnub no cov tuam txhab PCB tau them nyiaj ntau dua rau kev siv cov khoom siv tooj liab tuab los daws cov thermal efficiency ntawm high-power electronics.
Cov tuab-tooj ​​liab PCBs feem ntau loj tam sim no substrate, thiab cov PCBs loj tam sim no feem ntau yog siv rau hauv lub zog module thiab cov khoom siv hluav taws xob hauv tsheb. Ib txwm siv tsheb, hluav taws xob, thiab hluav taws xob hluav taws xob siv hluav taws xob siv cov ntaub ntawv tseem ceeb ntawm kev sib kis xws li xaim cable thiab cov ntawv hlau. Tam sim no cov tuab-tooj ​​liab boards hloov daim ntawv sib kis, uas tsis tsuas yog tuaj yeem txhim kho cov khoom tsim tau thiab txo lub sij hawm tus nqi ntawm kev xaim, tab sis kuj nce kev ntseeg siab ntawm cov khoom kawg. Nyob rau tib lub sijhawm, cov boards loj heev tam sim no tuaj yeem txhim kho kev tsim kev ywj pheej ntawm kev xaim, yog li paub txog qhov miniaturization ntawm tag nrho cov khoom.
Thick-tooj ​​liab Circuit Court PCB ua lub luag haujlwm hloov tsis tau hauv cov ntawv thov nrog lub zog siab, siab tam sim no, thiab kev xav tau txias siab. Cov txheej txheem tsim khoom thiab cov khoom siv hnyav-tooj ​​liab PCBS muaj ntau qhov kev xav tau ntau dua li cov qauv PCBs. Nrog cov cuab yeej siv siab heev thiab cov kws tshaj lij engineers, YMS muab cov tuab-tooj ​​liab PCBs nrog cov khoom zoo rau cov neeg siv khoom hauv tsev thiab txawv teb chaws.
