Annealing Rolled Copper Foil: Qhib Kev Ua Haujlwm Zoo Dua Rau Cov Ntawv Thov Siab Dua

Hauv cov lag luam siv thev naus laus zis siab xws li kev tsim khoom siv hluav taws xob, lub zog rov ua dua tshiab, thiab aerospace,ntawv ci tooj liab dovyog qhov muaj nqis rau nws qhov kev coj ua zoo heev, malleability, thiab qhov chaw du. Txawm li cas los xij, yog tsis muaj kev annealing zoo, cov ntawv ci tooj liab dov tuaj yeem raug kev txom nyem los ntawm kev ua haujlwm hardening thiab kev ntxhov siab seem, txwv nws txoj kev siv tau. Annealing yog ib qho txheej txheem tseem ceeb uas txhim kho cov microstructure ntawmntawv ci tooj liab, txhim kho nws cov khoom rau cov ntawv thov uas nyuaj. Tsab xov xwm no tshawb nrhiav txog cov ntsiab cai ntawm kev ua kom sov, nws qhov cuam tshuam rau kev ua haujlwm ntawm cov khoom siv, thiab nws qhov tsim nyog rau ntau yam khoom lag luam siab.

1. Cov Txheej Txheem Annealing: Hloov pauv Microstructure rau Cov Khoom Zoo Tshaj Plaws

Thaum lub sijhawm dov, cov siv lead ua los ntawm tooj liab raug nias thiab ntev, tsim cov qauv fibrous uas muaj cov kev tawg thiab kev ntxhov siab seem. Qhov kev ua haujlwm no ua rau muaj kev tawv ntxiv, txo qhov ductility (ntev tsuas yog 3% -5%), thiab txo qis me ntsis ntawm kev coj ua mus txog li 98% IACS (International Annealed Copper Standard). Annealing daws cov teeb meem no los ntawm kev tswj hwm "kev kub-tuav-txias" ua ntu zus:

1. Theem cua sov: Lubntawv ci tooj liabyog cua sov rau nws qhov kub recrystallization, feem ntau ntawm 200-300 ° C rau tooj liab ntshiab, los ua kom lub zog atomic txav mus los.
2. Kev Tuav TheemKev tswj qhov kub no li 2-4 teev yuav ua rau cov noob tawg ua tej daim me me, thiab cov noob tshiab, uas sib npaug zos los tsim, nrog rau qhov loj li ntawm 10-30μm.
3. Theem TxiasQhov txias qeeb ntawm ≤5°C/min tiv thaiv kev nkag mus ntawm kev ntxhov siab tshiab.

Cov Ntaub Ntawv Txhawb Nqa:

• Qhov kub ntawm kev ua kom cov hlau kub hnyiab ncaj qha cuam tshuam rau qhov loj ntawm cov hlau. Piv txwv li, thaum kub txog 250°C, cov hlau loj li ntawm 15μm, ua rau lub zog tensile ntawm 280 MPa. Thaum kub txog 300°C, cov hlau loj dua mus txog 25μm, thiab lub zog txo mus txog 220 MPa.
• Lub sijhawm tuav kom tsim nyog yog qhov tseem ceeb heev. Thaum kub txog 280°C, tuav tau 3 teev yuav ua kom muaj kev rov ua dua tshiab ntau dua 98%, raws li tau txheeb xyuas los ntawm kev tshuaj xyuas X-ray diffraction.

2. Cov Khoom Siv Annealing Siab Tshaj Plaws: Kev Tiv Thaiv Kev Ua Kom Tiav Thiab Kev Tiv Thaiv Oxidation

Kev ua kom kub hnyiab zoo xav tau cov cub tawg tshwj xeeb uas tiv thaiv roj kom ntseeg tau tias qhov kub sib npaug thiab tiv thaiv kev oxidation:

1. Tsim Lub Cub Hluav Taws XobKev tswj qhov kub thiab txias ywj pheej ntawm ntau thaj chaw (piv txwv li, kev teeb tsa rau thaj chaw) ua kom qhov kub thiab txias hloov pauv thoob plaws qhov dav ntawm daim ntawv ci tseem nyob hauv ± 1.5 ° C.
2. Huab Cua Tiv ThaivKev siv cov nitrogen uas muaj purity siab (≥99.999%) lossis cov nitrogen-hydrogen sib xyaw (3%-5% H₂) ua rau cov pa oxygen qis dua 5 ppm, tiv thaiv kev tsim cov tooj liab oxides (oxide txheej tuab <10 nm).
3. Kev Thauj Mus LosKev thauj mus los uas tsis muaj kev sib txhuam ua rau daim ntawv ci tiaj tus. Cov cub tawg annealing ntsug siab heev tuaj yeem ua haujlwm ntawm qhov ceev txog li 120 meters ib feeb, nrog rau lub peev xwm txhua hnub ntawm 20 tons ib lub cub tawg.

Kev Kawm Txog Cov Ntaub NtawvIb tug neeg siv khoom siv lub cub tawg uas tsis yog inert gas annealing tau ntsib kev oxidation liab ntawm qhovntawv ci tooj liabqhov chaw (cov pa oxygen txog li 50 ppm), ua rau muaj burrs thaum lub sijhawm etching. Hloov mus rau lub cub tawg tiv thaiv huab cua ua rau qhov roughness ntawm qhov chaw (Ra) ntawm ≤0.4μm thiab txhim kho cov txiaj ntsig etching mus txog 99.6%.

3. Kev Txhim Kho Kev Ua Haujlwm: Los ntawm "Cov Khoom Siv Raw Hauv Kev Lag Luam" mus rau "Cov Khoom Siv Ua Haujlwm"

Annealed tooj liab ntawv ciqhia txog kev txhim kho tseem ceeb:

Cov kev txhim kho no ua rau cov ntawv ci tooj liab annealed zoo tagnrho rau:

1. Cov Voj Voog Luam Tawm Yooj Yim (FPCs): Nrog rau kev ntev tshaj 20%, cov ntawv ci no tiv taus ntau tshaj 100,000 lub voj voog khoov dynamic, ua tau raws li qhov xav tau ntawm cov khoom siv foldable.
2. Cov Khoom Siv Sau Tam Sim No ntawm Lithium-Ion BatteryCov ntawv ci mos dua (HV <90) tiv taus kev tawg thaum lub sijhawm txheej electrode, thiab cov ntawv ci 6μm nyias heev tswj tau qhov hnyav sib xws hauv ± 3%.
3. Cov Khoom Siv Zaus SiabQhov roughness ntawm qhov chaw qis dua 0.5μm txo qhov poob ntawm lub teeb liab, txo qhov poob ntawm kev ntxig los ntawm 15% ntawm 28 GHz.
4. Cov Khoom Siv Tiv Thaiv Hluav Taws XobKev coj hluav taws xob ntawm 101% IACS ua kom muaj kev tiv thaiv zoo tsawg kawg 80 dB ntawm 1 GHz.

4. CIVEN METAL: Kev Siv Tshuab Annealing Ua Tus Thawj Coj Hauv Kev Lag Luam

CIVEN METAL tau ua tiav ntau yam kev nce qib hauv kev siv tshuab annealing:

1. Kev Tswj Kub NtsuasSiv cov txheej txheem PID nrog cov lus teb infrared, ua tiav qhov kev tswj kub ntawm ± 1 ° C.
2. Kev Sealing Zoo Dua: Phab ntsa cua sov ob txheej nrog kev them nyiaj rau lub zog dynamic txo cov roj siv los ntawm 30%.
3. Kev Tswj Xyuas Kev Taw Qhia Txog Cov NplejLos ntawm kev gradient annealing, tsim cov ntawv ci nrog ntau qhov nyuaj raws li lawv qhov ntev, nrog rau qhov sib txawv ntawm lub zog hauv zos txog li 20%, tsim nyog rau cov khoom sib xyaw ua ke.

Kev lees paubCIVEN METAL's RTF-3 reverse-treated foil, post-annealing, tau raug lees paub los ntawm cov neeg siv khoom rau kev siv hauv 5G chaw nres tsheb PCBs, txo qhov poob dielectric mus rau 0.0015 ntawm 10 GHz thiab nce tus nqi kis tau los ntawm 12%.

5. Xaus Lus: Qhov Tseem Ceeb ntawm Kev Ua Kub Hauv Kev Tsim Cov Ntawv Nyiaj Tooj Liab

Kev ua kom kub hnyiab tsis yog ib qho txheej txheem "kub-txias" xwb; nws yog kev sib koom ua ke ntawm cov ntaub ntawv tshawb fawb thiab kev tsim kho. Los ntawm kev tswj cov yam ntxwv me me xws li cov ciam teb ntawm cov noob thiab kev tawg,ntawv ci tooj liabkev hloov pauv ntawm "ua haujlwm-nyuaj" mus rau lub xeev "ua haujlwm tau zoo", txhawb nqa kev nce qib hauv 5G kev sib txuas lus, tsheb fais fab, thiab thev naus laus zis hnav tau. Raws li cov txheej txheem annealing hloov zuj zus mus rau kev txawj ntse ntau dua thiab kev ruaj khov - xws li CIVEN METAL txoj kev loj hlob ntawm cov cub tawg hydrogen-powered txo CO₂ emissions los ntawm 40% - dov tooj liab ntawv ci tau npaj los qhib cov peev xwm tshiab hauv kev siv txiav-ntug.
