Annealing Rolled Copper Foil: Kutsegula Magwiridwe Abwino a Mapulogalamu Apamwamba

Mu mafakitale apamwamba monga kupanga zamagetsi, mphamvu zongowonjezwdwanso, ndi ndege,zojambulazo zamkuwa zokulungidwaimayamikiridwa chifukwa cha mphamvu yake yabwino kwambiri yoyendetsera zinthu, kusinthasintha, komanso malo ake osalala. Komabe, popanda kulumikizidwa bwino, zojambulazo zamkuwa zopindidwa zimatha kuvutika ndi kuuma kwa ntchito komanso kupsinjika kotsalira, zomwe zimalepheretsa kugwiritsidwa ntchito kwake. Kuphimba ndi njira yofunika kwambiri yomwe imakonza kapangidwe kake ka microstructurepepala la mkuwa, kukulitsa mphamvu zake kuti zigwiritsidwe ntchito movutikira. Nkhaniyi ikufotokoza mfundo za annealing, momwe imakhudzira magwiridwe antchito a zinthu, komanso momwe imagwiritsidwira ntchito pazinthu zosiyanasiyana zapamwamba.

1. Njira Yowonjezera: Kusintha Kapangidwe ka Kapangidwe ka Zinthu Zapamwamba

Pa nthawi yozungulira, makhiristo a mkuwa amakanikizidwa ndi kutalikitsidwa, zomwe zimapangitsa kuti ulusi ukhale wodzaza ndi kusokonezeka komanso kupsinjika kotsalira. Kulimba kumeneku kumapangitsa kuti kuuma kukhale kowonjezereka, kuchepetsedwa kwa ductility (kutalika kwa 3%-5%) yokha, komanso kuchepa pang'ono kwa conductivity kufika pa pafupifupi 98% IACS (International Annealed Copper Standard). Annealing imathetsa mavutowa kudzera mu "kutentha-kuzizira-kogwira" kolamulidwa:

1. Gawo Lotenthetsera: Thepepala la mkuwaimatenthedwa kufika kutentha kwake kofanana ndi kubwezeretsanso kwa crystallization, nthawi zambiri pakati pa 200-300°C kuti ipange mkuwa weniweni, kuti iyambe kuyendetsa ma atomu.
2. Gawo LogwiraKusunga kutentha kumeneku kwa maola 2-4 kumalola kuti tirigu wopotoka uwole, ndipo tirigu watsopano, wofanana, upangike, wokhala ndi kukula kuyambira 10-30μm.
3. Gawo Loziziritsa: Kuzizira pang'onopang'ono kwa ≤5°C/min kumalepheretsa kuyambitsa mavuto atsopano.

Deta Yothandizira:

• Kutentha kwa annealing kumakhudza mwachindunji kukula kwa tirigu. Mwachitsanzo, pa 250°C, tirigu wa pafupifupi 15μm umafika, zomwe zimapangitsa kuti mphamvu yokoka ikhale 280 MPa. Kuonjezera kutentha kufika pa 300°C kumakulitsa tirigu kufika pa 25μm, kuchepetsa mphamvu kufika pa 220 MPa.
• Nthawi yoyenera yogwira ntchito ndi yofunika kwambiri. Pa kutentha kwa 280°C, kugwira ntchito kwa maola atatu kumatsimikizira kuti makristalo opangidwanso ndi 98%, monga momwe zatsimikiziridwa ndi X-ray diffraction analysis.

2. Zipangizo Zapamwamba Zopangira Annealing: Kuteteza Moyenera ndi Kutulutsa Oxidation

Kuphimba bwino kumafuna uvuni wapadera wotetezedwa ndi mpweya kuti zitsimikizire kuti kutentha kumafalikira mofanana ndikuletsa okosijeni:

1. Kapangidwe ka Ng'anjo: Kuwongolera kutentha kodziyimira pawokha m'malo ambiri (monga, kukhazikika kwa madera asanu ndi limodzi) kumatsimikizira kuti kusiyana kwa kutentha m'lifupi mwa zojambulazo kumakhalabe mkati mwa ±1.5°C.
2. Mpweya Woteteza: Kuyambitsa nayitrogeni woyera kwambiri (≥99.999%) kapena kusakaniza kwa nayitrogeni-hydrogen (3%-5% H₂) kumasunga mpweya wochepa pansi pa 5 ppm, zomwe zimaletsa kupangika kwa ma oxide amkuwa (makulidwe a oxide layer <10 nm).
3. Dongosolo Lonyamulira: Kuyendetsa ma roller opanda kupsinjika kumasunga foil kukhala yopyapyala. Ma uvuni apamwamba opindika amatha kugwira ntchito pa liwiro lofika mamita 120 pamphindi, ndi mphamvu ya tsiku ndi tsiku ya matani 20 pa ng'anjo iliyonse.

Phunziro la NkhaniKasitomala wogwiritsa ntchito ng'anjo yosagwiritsa ntchito mpweya adakumana ndi kufiira kwa okosijeni papepala la mkuwapamwamba (mpweya wokwanira mpaka 50 ppm), zomwe zimapangitsa kuti pakhale ma burrs panthawi yocheka. Kusintha kupita ku ng'anjo yoteteza mpweya kunapangitsa kuti pamwamba pakhale roughness (Ra) ya ≤0.4μm ndipo kukongoletsa kukongoletsa kunafika pa 99.6%.

3. Kupititsa patsogolo Magwiridwe Antchito: Kuchokera ku "Zida Zopangira Mafakitale" mpaka "Zida Zogwirira Ntchito"

Zojambula zamkuwa zophimbidwa ndi Annealedakuwonetsa kusintha kwakukulu:

Zowonjezera izi zimapangitsa kuti pepala la mkuwa lopangidwa ndi annealed likhale labwino kwambiri pa:

1. Ma Circuits Osindikizidwa Osinthasintha (FPCs): Ndi kutalika kopitilira 20%, foilyo imatha kupindika maulendo opitilira 100,000, kukwaniritsa zofunikira za zida zopindika.
2. Osonkhanitsa Ma Battery a Lithium-Ion Current: Ma foil ofewa (HV<90) amakana kusweka akamapaka ma elekitirodi, ndipo ma foil opyapyala kwambiri a 6μm amasunga kulemera kofanana mkati mwa ±3%.
3. Ma Substrate Omwe Amasinthasintha Kwambiri: Kukhwima kwa pamwamba pansi pa 0.5μm kumachepetsa kutayika kwa chizindikiro, kuchepetsa kutayika kwa choyikira ndi 15% pa 28 GHz.
4. Zipangizo Zotetezera Magetsi: Kuthamanga kwa 101% IACS kumatsimikizira kuti chitetezo cha 80 dB pa 1 GHz chimagwira ntchito bwino.

4. CIVEN METAL: Ukadaulo Wotsogola Kwambiri pa Mafakitale

Kampani ya CIVEN METAL yapita patsogolo kwambiri paukadaulo wopangira zinthu zofewa:

1. Kulamulira Kutentha KwanzeruKugwiritsa ntchito ma algorithms a PID okhala ndi infrared feedback, kukwaniritsa kulondola kwa kutentha kwa ±1°C.
2. Kusindikiza Kowonjezereka: Makoma a ng'anjo okhala ndi zigawo ziwiri okhala ndi mphamvu yowonjezereka amachepetsa kugwiritsa ntchito mpweya ndi 30%.
3. Kuwongolera Kuyang'ana kwa Tirigu: Kudzera mu gradient annealing, kupanga ma foil okhala ndi kuuma kosiyanasiyana kutalika kwawo, ndi kusiyana kwa mphamvu komwe kulipo mpaka 20%, koyenera pazinthu zovuta zosindikizidwa.

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

5. Mapeto: Kufunika Kwambiri kwa Kuyika Zinthu mu Kupanga Foil ya Mkuwa

Kuyika zinthu m'nthaka si njira yongozizira kwambiri; ndi njira yophatikiza zinthu ndi uinjiniya. Mwa kusintha zinthu monga malire a tirigu ndi kusuntha kwa nthaka,pepala la mkuwakusintha kuchoka pa ntchito yolimba kupita ku ntchito "yogwira ntchito", zomwe zikuthandiza kupita patsogolo pa kulumikizana kwa 5G, magalimoto amagetsi, ndi ukadaulo wovalidwa. Pamene njira zothira mafuta zikusintha kupita ku nzeru zazikulu komanso kukhazikika—monga momwe CIVEN METAL imapangidwira popanga uvuni woyendetsedwa ndi hydrogen womwe umachepetsa mpweya wa CO₂ ndi 40%—zolembera zamkuwa zokulungidwa zakonzeka kutsegula zinthu zatsopano mu ntchito zamakono.
