Kev faib tawm los ntawm Kev Tsim Khoom
High-kawg tooj liab ntawv ci feem ntau muab faib ua ob pawg raws li kev tsim khoom:
Electrodeposited (ED) Copper Foil: Ua los ntawm electrochemical deposition. Nws tuav lub lag luam thoob ntiaj teb (kwv yees . 90%), muab tus nqi qis dua thiab muaj zog tensile ntau dua, tab sis muaj qhov yooj yim dua. Nws cov qauv nplej yog columnar, thiab tus qauv nto roughness (Rz) yog nyob ib ncig ntawm 7-8 μm, yuav tsum tau kho tshwj xeeb kom txo cov teeb liab poob rau kev siv ntau zaus. Advanced khoom muaj xws li:
HVLP daim ntawv: Nta ultra-tsawg profile nrog nto roughness Tsawg dua lossis sib npaug li 2.5 μm, siv hauv 5G hauv paus chaw nres tsheb thiab AI servers.
RTF daim ntawv: Siv rov qab- txheej txheem kho kom ua tiav qhov tsis zoo, nrog cov thev naus laus zis hloov mus los ntawm ntau tiam neeg.
Rolled thiab Annealed (RA) Copper Foil: Ua los ntawm lub cev dov thiab annealing. Nws muaj cov qauv fiber ntau, kev ua tau zoo dua qub (muaj peev xwm tiv taus kaum tawm txhiab tus khoov), thiab qhov chaw du (Rz Tsawg dua lossis sib npaug li 1.1 μm). Nws purity feem ntau yog ntau dua los yog sib npaug rau 99.9%, nrog me ntsis conductivity zoo dua ED ntawv ci. Advanced variants muaj xws li siab-kub los tiv thaiv- oxidation foil thiab nto-kho foils (xws li, blackened/reddened) rau txhim kho electromagnetic shielding.
Kev faib tawm los ntawm Thickness & Physical Properties
Qhov kev faib tawm no tsom mus rau cov kev xav tau tshwj xeeb ntawm kev ua haujlwm:
Ultra-Thin/Peelable Foil: Thickness ntau ntawm 3-12 μm. Tseem ceeb heev rau IC substrate thiab 2.5D / 3D siab ntim ntim, daws cov teeb meem hauv lub zog thiab txhim khu kev qha tev tawm ntawm qhov hnyav heev.
Hnyav/Thick Copper FoilThickness Ntau dua lossis sib npaug rau 70 μm (Ntau dua lossis sib npaug rau 2 oz / ft²). Tsim los rau siab -cov ntawv siv hluav taws xob xws li EV powertrains thiab lub zog cia modules, yuav tsum muaj lub zog tam sim no - nqa peev xwm, thermal conductivity, thiab tev lub zog.
Tsawg-Profile/Low-Poob Copper Foil: Engineered rau siab - zaus thiab siab - ceev circuits. Cov ntsiab lus tseem ceeb suav nrog qhov roughness tsawg dua lossis sib npaug li 2.5 μm thiab dielectric poob (Df) Tsawg dua lossis sib npaug rau 0.002. Kev thov yog tsav los ntawm 6G kev sib txuas lus thiab siab - cov chaw ceev cov ntaub ntawv, nrog rau AI servers siv ntau dua li ib txwm muaj.
Classification los ntawm Surface Treatment & Function
Kev hloov kho saum npoo ua kom muaj cov haujlwm tshwj xeeb:
Ob -Sided Smooth Foil: Ob tog muaj qhov roughness tsawg heev (tsawg dua lossis sib npaug li 1.3 μm). Siv nyob rau hauv siab - ntom ntom interconnect (HDI) boards rau smartphones thiab wearable devices.
Composite Copper Foil: Sawv cev rau kev cuam tshuam kev tsim kho tshiab, suav nrog:
Tooj-Aluminium Composite: Ua ke cov tooj liab conductivity nrog txhuas lub teeb yuag, txo tus nqi rau cov neeg siv khoom siv hluav taws xob roj teeb.
PET-Based Composite Foil: Features hlau -PET-hlau "sandwich" qauv, txiav tooj liab siv los ntawm ~ 70% thaum txhim kho kev nyab xeeb thiab lub zog ceev rau lithium - ion roj teeb. Lub khw no xav tias yuav loj hlob tuaj.
Kev faib tawm los ntawm Thawj Daim Ntawv Thov Field
Kev siv PCB: Kev lag luam thoob ntiaj teb rau siab -kawg PCB ntawv ci tau loj hlob tsis tu ncua. Cov txheej txheem thev naus laus zis tau taw qhia mus rau ib txwm muaj - qis roughness (piv txwv li, Tsawg dua lossis sib npaug li 0.3 μm rau qhov tseeb - tiam HVLP) thiab cov foils nyias (< 3 μm), driving upgrades in electrolytes and production equipment.
Lithium-Ion Battery Applications: Categorized los ntawm thickness rau hauv ultra-nyias (tsawg dua los yog sib npaug rau 6 μm), nyias (6-12 μm), thiab txheem (12-18 μm). Qhov sib txawv yog mus rau nyias foils kom muaj roj teeb lub zog ceev, nrog rau kev lag luam ntau lawm ntawm 4.5 μm thickness.
Environmental & Industry Trends
Kev lag luam yog zoo li los ntawm ob lub zog loj:
Green Manufacturing: Cov kev cai ib puag ncig tau thawb kev siv lead ua - cov txheej txheem dawb, chromium- pub dawb passivation, thiab cov dej khib nyiab siab tshaj rov ua dua tshiab thiab kho tshuab.
Kev Txhim Kho Cov Khoom Siv Hauv Tsev: Kev tsim khoom hauv zos ntawm siab -kawg tooj liab foils yog nrawm. Kev sib koom ua lag luam rau cov khoom lag luam hauv tsev ua tau siab heev PCB ntawv nyiaj tau npaj siab yuav nce ntxiv, nrog rau cov tuam txhab paub txog cov thev naus laus zis tseem ceeb thiab ua tiav qhov ntsuas yuav ua rau kev loj hlob yav tom ntej.
Cov txheej txheem kev faib tawm rau siab -kawg tooj liab ntawv ci qhia txog kev lag luam tsis tu ncua ntawm kev ua haujlwm ntawm cov khoom siv. Los ntawm cov txheej txheem kho kom zoo ntawm ED ntawv ci mus rau qhov hloov pauv siab ntawm RA foil, thiab los ntawm kev tawg hauv ultra- cov ntawv nyias nyias mus rau kev cuam tshuam cov qauv sib xyaw, thaj chaw tau hloov zuj zus mus rauthinner, qis dua - poob, thiab siab dua - kev cia siabcov ntaub ntawv. Kev nrawm nrawm ntawm kev tsim khoom hauv tsev thiab cov qauv nruj dua ib puag ncig yuav yog tus tsav tsheb tseem ceeb, thawb kev lag luam mus rau kev txhim kho zoo dua.
