Ntawm ntau qhov tsis sib xws ntawm Circuit Board, tooj liab foil thickness qauv ua lub luag haujlwm tseem ceeb. Nws ncaj qha cuam tshuam rau kev ua tau zoo thiab kev ruaj ntseg ntawm kev sib kis tam sim no, thiab cuam tshuam rau kev ua haujlwm ntawm tag nrho cov tshuab hluav taws xob.
1, Common copper foil thickness specifications
Lub thickness ntawm tooj liab ntawv ci ntawm Circuit Court boards feem ntau yog ntsuas nyob rau hauv ounces los yog micrometers. Hauv kev ua lag luam, cov kev qhia tshwj xeeb muaj ntau haiv neeg thiab ntau tshaj . 1oz, txog 35 μ m, yog suav tias yog qhov tseem ceeb tshaj plaws thiab dav siv tuab. Txawm hais tias nws yog niaj hnub computer motherboards, ntsiav tshuaj Circuit Court boards, los yog cov neeg siv khoom siv hluav taws xob hauv Circuit Court boards, qhov tuab no feem ntau siv vim tias nws ua tiav qhov sib npaug ntawm cov khoom siv hluav taws xob thiab cov nqi, thiab tuaj yeem ua tau raws li cov kev xav tau ntawm feem ntau cov circuits. Copper foil nrog lub thickness ntawm 2oz yog zoo heev nyob rau hauv teb uas yuav tsum tau nruj tam sim no nqa peev xwm, xws li siab - fais fab mov module Circuit Court boards thiab industrial qib siab - khoom siv hluav taws xob circuit boards. Nyob rau hauv cov xwm txheej no, cov tam sim no siab txuas ntxiv mus, thiab cov ntawv ci tooj liab tuab tuaj yeem txo qhov kev tiv thaiv, kev tsim hluav taws xob, thiab lub zog poob, ua kom muaj kev ruaj ntseg ntawm Circuit Court . 0.5oz nyias cov ntawv ci tooj liab yog qhov nyiam heev hauv cov khoom siv hluav taws xob uas muaj zog thov rau miniaturization thiab hnav vim nws qhov zoo ntawm kev sib sib zog nqus thiab ua haujlwm me me. Piv txwv li, Circuit Court boards rau cov khoom siv hnav xws li smartwatches thiab Bluetooth earphones tuaj yeem ua tiav qhov kev teeb tsa hauv Circuit Court hauv qhov chaw tsawg. Tsis tas li ntawd, nyob rau hauv ib co tshwj xeeb customized Circuit Court boards uas tsis tshua muaj siab yuav tsum tau tam sim no nqa los yog tshav kub dissipation, 3oz, 4oz los yog txawm thicker tooj liab foils kuj yuav siv tau.
2, Thickness xaiv cov txheej txheem nyob rau hauv txawv scenarios
Cov khoom siv hluav taws xob: Siv cov xov tooj ntawm tes ua piv txwv, qhov chaw sab hauv yog qhov tseem ceeb thiab yuav tsum muaj kev sib koom ua ke ntawm ntau qhov kev ua haujlwm. Lub rooj tsav xwm Circuit Court feem ntau siv cov ntawv ci tooj liab nrog lub thickness ntawm 0.5oz-1oz. Ntawm qhov tod tes, qhov tam sim no ntawm lub xov tooj ntawm tes yog qhov me me thaum lub sijhawm ua haujlwm, yog li tsis tas yuav tsum muaj cov ntawv ci tooj liab tuab kom nqa tau siab tam sim no; Ntawm qhov tod tes, daim ntawv nyias nyias tuaj yeem txo qhov tuab thiab qhov hnyav ntawm lub rooj tsav xwm Circuit Court, uas yog nyob rau hauv txoj kab nrog cov qauv ntawm lub teeb yuag tsim ntawm lub xov tooj ntawm tes. Nyob rau tib lub sijhawm, nws tuaj yeem txo cov kab mob parasitic thaum lub sij hawm xaim hluav taws xob, xyuas kom meej cov teeb liab, thiab txhim kho kev sib txuas lus zoo.
Cov cuab yeej tswj kev lag luam: Cov chaw muaj kev lag luam yog qhov nyuaj, thiab cov khoom siv ua haujlwm feem ntau nrog cov hluav taws xob siab thiab siab tam sim no. Lub rooj tsav xwm Circuit Court ntawm cov tswj lub cev muaj zog loj feem ntau siv cov ntawv ci tooj liab nrog lub thickness ntawm 2oz lossis siab dua. Cov ntawv ci tooj liab tuaj yeem tiv taus qhov muaj zog tam sim no, txo cov cua sov los ntawm kev ua haujlwm, txhim khu kev ntseeg tau thiab ruaj khov ntawm Circuit Court boards nyob rau hauv hnyav kev lag luam ib puag ncig, zam faults los ntawm overheating thiab overcurrent, thiab xyuas kom meej lub continuation ntawm industrial ntau lawm.
Cov khoom siv sib txuas lus siab: Hauv siab - cov xwm txheej sib txuas lus ntau zaus xws li 5G hauv paus chaw nres tsheb Circuit Court boards, qhov yuav tsum tau muaj rau cov ntawv ci tooj liab yog qhov tseeb dua. Nws yog tsim nyog los xyuas kom meej zoo conductivity thaum txo cov teeb liab kis tau tus mob. Feem ntau, cov ntawv ci tooj liab nrog lub thickness ntawm txog 1oz thiab ua ke nrog cov txheej txheem tshwj xeeb saum npoo yog xaiv. Cov ntawv ci tooj liab tuaj yeem txo qhov cuam tshuam ntawm daim tawv nqaij, txo lub zog poob thaum lub teeb liab kis tau tus mob ntawm cov ntawv ci tooj liab, ua kom muaj txiaj ntsig zoo thiab ruaj khov kis tau tus mob siab - zaus teeb liab, thiab ua tau raws li cov kev cai nruj ntawm 5G kev sib txuas lus rau kev kub ceev thiab qis latency.
3, Kev cuam tshuam ntawm cov qauv tuab ntawm kev ua haujlwm ntawm cov rooj tsav xwm hauv Circuit Court
Conductivity: Lub thickness ntawm tooj liab ntawv nyiaj yog ze ze rau nws conductivity. Raws li lub thickness nce, tus ntoo khaub lig-sectional cheeb tsam nce, thiab cov kev tiv thaiv kuj txo. Raws li Ohm txoj cai lij choj, ntawm tib qhov hluav taws xob, qhov me me ntawm qhov tsis kam, qhov kev sib kis tau yooj yim dua, thiab lub zog poob qis dua. Hauv cov kab hluav taws xob siab tam sim no, siv 2oz tooj liab ntawv ci tuaj yeem txo cov kab hluav taws xob poob qis thiab txhim kho lub zog xa hluav taws xob piv rau 1oz tooj liab ntawv ci.
Thaum tshav kub kub dissipation muaj peev xwm: Thaum lub rooj tsav xwm Circuit Court ua haujlwm, nws ua kom muaj cua sov vim qhov dhau ntawm tam sim no. Copper foil, raws li ib qho ntawm cov cua kub dissipation channel, nws cov thickness cuam tshuam rau cov cua sov dissipation nyhuv. Cov ntawv ci tooj liab muaj qhov dav dav ntawm txoj kev tshav kub thiab tuaj yeem ua kom sov sai dua. Nyob rau hauv siab - lub zog LED teeb pom kev zoo tsav tsheb Circuit Court boards, siv cov ntawv ci tooj liab tuab pab txo qhov kub ntawm LED chips, txuas lawv lub neej kev pab cuam, thiab txhim kho tag nrho cov kev ua tau zoo ntawm lub teeb pom kev zoo.
Mechanical zog: Rau qee qhov, cov ntawv ci tooj liab tuab tuaj yeem txhim kho lub zog ntawm cov khoom siv hluav taws xob. Nyob rau hauv cov xwm txheej uas cov khoom siv hluav taws xob tuaj yeem raug kev co thiab cuam tshuam, cov ntawv ci tooj liab tuab tuaj yeem ua rau lub rooj tsav xwm hauv Circuit Court resistant rau dabtsi yog khoov thiab tsis tshua muaj kev tawg, ua kom muaj kev ruaj ntseg ntawm kev sib txuas hauv Circuit Court thiab txo qhov kev pheej hmoo ntawm Circuit Court breaks, luv circuits, thiab lwm yam kev ua txhaum los ntawm txhua yam kev ntxhov siab.
