Annealing Copper Foil: Kutsegula Magwiridwe Owonjezera a Mapulogalamu Apamwamba

M'mafakitale apamwamba kwambiri monga kupanga zamagetsi, mphamvu zongowonjezwdwa, ndi zakuthambo,adagulung'undisa mkuwa zojambulazondi yamtengo wapatali chifukwa cha kusinthasintha kwake, kusungunuka, komanso pamwamba pake. Komabe, popanda kuyika bwino, zojambula zamkuwa zopindidwa zimatha kuvutitsidwa ndi kuuma kwa ntchito komanso kupsinjika kotsalira, ndikuchepetsa kugwiritsidwa ntchito kwake. Annealing ndi njira yovuta kwambiri yomwe imakonza microstructure yazojambula zamkuwa, kukulitsa katundu wake pakugwiritsa ntchito movutikira. Nkhaniyi ikufotokoza za mfundo za annealing, momwe zimakhudzira ntchito zakuthupi, komanso kuyenera kwake pazinthu zosiyanasiyana zapamwamba.

1. Njira Yowonjezera: Kusintha kwa Microstructure kwa Zapamwamba Zapamwamba

Panthawi yogubuduza, makhiristo amkuwa amapanikizidwa ndikutalikitsidwa, ndikupanga mawonekedwe a ulusi wodzaza ndi kusokonezeka komanso kupsinjika kotsalira. Kuwumitsa ntchito kumeneku kumabweretsa kuuma kowonjezereka, kuchepetsedwa kwa ductility (elongation ya 3% -5% yokha), ndi kuchepa pang'ono kwa conductivity mpaka pafupifupi 98% IACS (International Annealed Copper Standard). Annealing imayankha izi kudzera mundondomeko yoyendetsedwa ndi "kutentha-kusunga-kuzizira":

1. Kutentha Gawo: Ndizojambula zamkuwaimatenthedwa mpaka kutentha kwake, komwe kumakhala pakati pa 200-300 ° C kwa mkuwa wangwiro, kuti ayambitse kuyenda kwa atomiki.
2. Holding Phase: Kusunga kutentha kumeneku kwa maola 2-4 kumapangitsa kuti mbewu zopotoka ziwonongeke, ndipo mbewu zatsopano, zofanana, zomwe zimakhala ndi kukula kwa 10-30μm.
3. Gawo Lozizira: Kuzizira pang'onopang'ono kwa ≤5 ° C / min kumalepheretsa kuyambitsa zovuta zatsopano.

Kuthandizira Data:

• Kutentha kwa Annealing kumakhudzanso kukula kwambewu. Mwachitsanzo, pa 250 ° C, mbewu za pafupifupi 15μm zimapindula, zomwe zimapangitsa kuti mphamvu ya 280 MPa ikhale yolimba. Kuchulukitsa kutentha mpaka 300 ° C kumakulitsa mbewu mpaka 25μm, kuchepetsa mphamvu mpaka 220 MPa.
• Kusunga nthawi yoyenera ndikofunikira. Pa 280 ° C, kugwira kwa maola atatu kumapangitsa kuti 98% iwonetsedwenso, monga kutsimikiziridwa ndi X-ray diffraction analysis.

2. Zida Zowonjezera Zowonjezera: Precision and Oxidation Prevention

Kuwotchera koyenera kumafuna ng'anjo zapadera zotetezedwa ndi mpweya kuti zitsimikizire kugawa kwa kutentha kofanana ndikupewa okosijeni:

1. Furnace Design: Kuwongolera kutentha kodziyimira pawokha kwamitundu ingapo (mwachitsanzo, masinthidwe a magawo asanu ndi limodzi) kumawonetsetsa kuti kusintha kwa kutentha kudutsa m'lifupi mwa zojambulazo kumakhalabe mkati mwa ± 1.5°C.
2. Kuteteza Atmosphere: Kuyambitsa nayitrogeni yoyera kwambiri (≥99.999%) kapena kusakaniza kwa nayitrogeni-hydrogen (3% -5% H₂) kumasunga milingo ya okosijeni pansi pa 5 ppm, kuletsa kupanga ma oxides amkuwa (kuchuluka kwa oxide wosanjikiza <10 nm).
3. Conveyance System: Zoyendera zopanda kupsinjika zimathandizira kuti zojambulazo zikhale zosalala. ng'anjo zapamwamba zowongoka zimatha kugwira ntchito mwachangu mpaka 120 metres pamphindi, ndikutha tsiku lililonse matani 20 pang'anjo iliyonse.

Nkhani Yophunzira: Makasitomala omwe amagwiritsa ntchito ng'anjo yoyatsira gasi yopanda mafuta adakumana ndi ma oxidation ofiira pazojambula zamkuwapamwamba (zokhala ndi okosijeni mpaka 50 ppm), zomwe zimatsogolera ku ma burrs pakuwotcha. Kusinthira ku ng'anjo yoteteza mpweya kunapangitsa kuti pakhale roughness (Ra) ya ≤0.4μm komanso zokolola zabwino za etching mpaka 99.6%.

3. Kupititsa patsogolo Kachitidwe: Kuchokera ku "Industrial Raw Material" kupita ku "Functional Material"

Annealed mkuwa zojambulazozikuwonetsa kusintha kwakukulu:

Zowonjezera izi zimapangitsa kuti zojambulazo zikhale zabwino kwa:

1. Flexible Printed Circuits (FPCs): Ndi kutalika kopitilira 20%, zojambulazo zimapirira mikombero yopindika yopitilira 100,000, kukwaniritsa zofuna za zida zopindika.
2. Zotolera Zamakono Za Battery Lithium-Ion: Zojambula zofewa (HV <90) zimakana kusweka panthawi yopaka ma elekitirodi, ndipo zojambulazo zowonda kwambiri za 6μm zimasunga kulemera kosasinthasintha mkati mwa ± 3%.
3. Magawo Apamwamba-Frequency: Kuvuta kwapamtunda pansi pa 0.5μm kumachepetsa kutayika kwa chizindikiro, kumachepetsa kutayika kwa kuika ndi 15% pa 28 GHz.
4. Zida Zotchingira za Electromagnetic: Conductivity ya 101% IACS imatsimikizira chitetezo cha osachepera 80 dB pa 1 GHz.

4. CIVEN METAL: Upainiya Wotsogola Wotsogola waukadaulo wa Annealing

CIVEN METAL yachita zotsogola zingapo paukadaulo wa annealing:

1. Kutentha kwanzeru: Kugwiritsa ntchito ma algorithms a PID okhala ndi mayankho a infrared, kukwaniritsa kuwongolera kutentha kwa ± 1 ° C.
2. Kusindikiza Kowonjezera: Makoma a ng'anjo yamitundu iwiri yokhala ndi chiwongola dzanja champhamvu amachepetsa kugwiritsa ntchito gasi ndi 30%.
3. Grain Orientation Control: Kupyolera mu gradient annealing, kutulutsa zojambulazo zolimba mosiyanasiyana kutalika kwake, ndi kusiyana kwamphamvu komwe kumakhalako mpaka 20%, oyenera zigawo zovuta zosindikizidwa.

Kutsimikizira: CIVEN METAL's RTF-3 reverse-treated foil, post-annealing, yatsimikiziridwa ndi makasitomala kuti agwiritsidwe ntchito mu 5G base station PCBs, kuchepetsa kutayika kwa dielectric ku 0.0015 pa 10 GHz ndikuwonjezera maulendo opatsirana ndi 12%.

5. Kutsiliza: Kufunika Kwambiri kwa Annealing mu Copper Foil Production

Annealing ndi zambiri kuposa "kutentha-kuzizira" ndondomeko; ndi kuphatikiza kwaukadaulo kwazinthu sayansi ndi uinjiniya. Pogwiritsa ntchito mawonekedwe a microstructural monga malire a tirigu ndi ma dislocation,zojambula zamkuwakusintha kuchokera ku "ntchito yolemetsa" kupita ku dziko "logwira ntchito", kulimbikitsa kupita patsogolo kwa mauthenga a 5G, magalimoto amagetsi, ndi teknoloji yovala. Pamene njira zowonjezeretsa zikupita ku nzeru zochulukirapo komanso kukhazikika - monga CIVEN METAL kupanga ng'anjo zoyendetsedwa ndi haidrojeni kuchepetsa mpweya wa CO₂ ndi 40% - zojambula zamkuwa zokulungidwa zatsala pang'ono kutsegula zatsopano pakugwiritsa ntchito njira zamakono.
