1.Txoj kev tsim keeb kwm ntawm tooj liab ntawv ci
Keeb kwm ntawmtooj liab ntawv cituaj yeem taug qab rov qab mus rau xyoo 1930s, thaum American inventor Thomas Edison tau tsim ib daim ntawv pov thawj rau kev tsim khoom txuas ntxiv ntawm cov ntawv hlau nyias, uas tau los ua tus pioneer ntawm niaj hnub electrolytic tooj liab ntawv ci tshuab. Tom qab ntawd, Nyiv tau tshaj tawm thiab tsim cov thev naus laus zis no hauv xyoo 1960, thiab Tuam Tshoj tau ua tiav qhov loj ntawm cov ntawv ci tooj liab nyob rau thaum ntxov 1970s.
2.Classification ntawm tooj liab ntawv ci
tooj liab ntawv ciFeem ntau yog muab faib ua ob pawg: dov tooj liab ntawv ci (RA) thiab electrolytic tooj liab ntawv ci (ED).
Rolled tooj liab ntawv ci:ua los ntawm lub cev txhais tau tias, nrog du nto, zoo heev conductivity thiab tus nqi siab.
Electrolytic tooj liab ntawv ci:ua los ntawm electrolytic deposition, nrog tus nqi qis, thiab yog cov khoom tseem ceeb ntawm kev ua lag luam.
Ntawm lawv, electrolytic tooj liab ntawv ci tuaj yeem muab faib ua ntau hom kom tau raws li cov kev xav tau sib txawv:
● HTE tooj liab ntawv nyiaj:kub tsis kam, siab ductility, haum rau ntau txheej PCB boards, xws li cov servers ua haujlwm siab thiab cov khoom siv avionics.
Case: Inspur Information's high-performance servers siv HTE copper foil los hais txog kev tswj xyuas thermal thiab teeb liab teeb meem kev ncaj ncees hauv kev ua haujlwm siab.
● RTF tooj liab ntawv ci:Txhim kho qhov adhesion ntawm tooj liab ntawv nyiaj thiab insulating substrate, feem ntau siv nyob rau hauv automotive electronic control units.
Case: CATL's roj teeb tswj system siv RTF tooj liab ntawv ci los xyuas kom meej kev ntseeg tau thiab ruaj khov nyob rau hauv huab cua txias.
● ULP tooj liab ntawv ci:ultra-low profile, txo cov thickness ntawm PCB boards, haum rau nyias cov khoom siv hluav taws xob xws li smartphones.
Case: Xiaomi's smartphone motherboard siv ULP tooj liab ntawv ci kom ua tiav cov qauv sib dua thiab nyias.
● HVLP tooj liab ntawv nyiaj:high-frequency ultra-low profile tooj liab ntawv ci, tshwj xeeb tshaj yog muaj nuj nqis los ntawm kev ua lag luam rau nws cov teeb liab kis tau zoo heev. Nws muaj qhov zoo ntawm qhov siab hardness, du roughened nto, zoo thermal stability, uniform thickness, thiab lwm yam, uas tuaj yeem txo cov teeb liab poob hauv cov khoom hluav taws xob. Nws yog siv rau high-ceev kis tau tus mob PCB boards xws li high-end servers thiab cov ntaub ntawv chaw.
Case: Tsis ntev los no, Solus Advanced Materials, yog ib qho ntawm Nvidia cov neeg muab khoom tseem ceeb CCL hauv Kaus Lim Qab Teb, tau txais Nvidia daim ntawv tso cai tsim khoom loj kawg thiab yuav muab HVLP tooj liab ntawv ci rau Doosan Electronics rau siv hauv Nvidia tiam tshiab ntawm AI accelerators uas Nvidia npaj yuav tshaj tawm xyoo no.
3.Application industries thiab rooj plaub
● Printed Circuit Board (PCB)
tooj liab ntawv ci, raws li cov txheej txheem ntawm PCB, yog ib qho tseem ceeb ntawm cov khoom siv hluav taws xob.
Case: Lub rooj tsavxwm PCB siv hauv Huawei tus neeg rau zaub mov muaj cov ntawv ci tooj liab siab kom ua tiav cov qauv tsim hluav taws xob thiab cov ntaub ntawv ceev ceev.
● Lithium-ion roj teeb
Raws li qhov tsis zoo electrode tam sim no collector, tooj liab ntawv ua lub luag haujlwm tseem ceeb hauv lub roj teeb.
Case: CATL's lithium-ion roj teeb siv cov hluav taws xob electrolytic copper foil, uas txhim kho lub roj teeb lub zog ceev thiab kev them nqi thiab kev ua haujlwm tawm.
●Electromagnetic shielding
Hauv cov khoom siv kho mob MRI thiab cov chaw sib txuas lus, cov ntawv ci tooj liab yog siv los tiv thaiv electromagnetic cuam tshuam.
Case: United Imaging Medical's MRI cov cuab yeej siv cov khoom siv tooj liab rau electromagnetic shielding, kom ntseeg tau qhov tseeb thiab qhov tseeb ntawm cov duab.
● Yooj yim luam tawm Circuit Board
Rolled tooj liab ntawv ci yog tsim rau cov khoom siv hluav taws xob kho tau vim nws qhov yooj yim.
Case: Xiaomi wristband siv lub PCB hloov tau yooj yim, qhov twg tooj liab ntawv ci muab txoj hauv kev tsim nyog thaum tswj qhov hloov pauv ntawm lub cuab yeej.
● Consumer electronics, computers thiab lwm yam khoom siv
Copper foil plays lub luag haujlwm tseem ceeb hauv motherboards ntawm cov khoom siv xws li smartphones thiab laptops.
Case: Huawei's MateBook series ntawm lub laptops siv cov ntawv ci tooj liab zoo heev los xyuas kom meej qhov kev ua tau zoo thiab kev ntseeg siab ntawm lub cuab yeej.
● Automotive electronics Nyob rau hauv cov tsheb niaj hnub
Cov ntawv ci tooj liab yog siv rau hauv cov khoom siv hluav taws xob tseem ceeb xws li lub cav tswj cov cav thiab cov roj teeb tswj cov tshuab.
Case: Weilai lub tsheb hluav taws xob siv cov ntawv ci tooj liab los txhim kho cov roj teeb kom zoo thiab kev nyab xeeb.
● Hauv cov khoom siv sib txuas lus xws li 5G hauv paus chaw nres tsheb thiab routers
tooj liab ntawv ci yog siv los ua kom tau cov ntaub ntawv ceev ceev.
Case: Huawei's 5G lub hauv paus chaw nres tsheb cov cuab yeej siv cov ntawv ci tooj liab ua tau zoo los txhawb kev xa cov ntaub ntawv ceev thiab kev ua haujlwm.
