I-Annealing Copper Foil: Ukuvula Ukusebenza Okuthuthukisiwe Kwezinhlelo Zokusebenza Ezithuthukile

Ezimbonini zobuchwepheshe obuphezulu njengokukhiqiza i-electronics, amandla avuselelekayo, kanye ne-aerospace,i-foil yethusi egoqweibaluleke kakhulu ngenxa ye-conductivity yayo enhle kakhulu, ukusebenziseka kalula, kanye nendawo ebushelelezi. Kodwa-ke, ngaphandle kokufakwa kahle kwe-anneal, ucwecwe lwethusi olugoqiwe lungahlupheka ngenxa yokuqina komsebenzi kanye nengcindezi eyinsalela, kunciphise ukusebenziseka kwayo. I-Annealing kuyinqubo ebucayi ecolisa i-microstructure yeucwecwe lwethusi, ithuthukisa izakhiwo zayo zezicelo ezifunayo. Lesi sihloko sidingida emigomeni yokudonsa, umthelela wayo ekusebenzeni kwempahla, nokufaneleka kwayo emikhiqizweni ehlukahlukene esezingeni eliphezulu.

1. Inqubo Yokuhlanganisa: Ukuguqula I-Microstructure Yezakhiwo Eziphakeme

Phakathi nenqubo yokugoqa, amakristalu ethusi ayacindezelwa futhi anwetshwe, okwenza isakhiwo esine-fibrous esigcwele ukuhlukaniswa nokucindezeleka okusele. Lo msebenzi wokuqina uphumela ekukhuleni kokuqina, ukuncipha kwe-ductility (ukwelula okungu-3% -5%) kuphela, kanye nokuncipha kancane kokuqhutshwa kwe-conductivity kuya cishe ku-98% IACS (International Annealed Copper Standard). I-Annealing ibhekana nalezi zinkinga ngokulandelana okulawulwayo kokuthi "i-heating-holding-cooling":

1. Isigaba Sokushisa: Iucwecwe lwethusiishisiswe kumazinga okushisa ayo okuvuselela kabusha, ngokuvamile phakathi kuka-200-300 ° C ukuze uthole ithusi elihlanzekile, ukuze kusebenze ukunyakaza kwe-athomu.
2. Isigaba sokubamba: Ukugcina lokhu kushisa kwamahora angu-2-4 kuvumela okusanhlamvu okuhlanekezelwe ukubola, kanye nezinhlamvu ezintsha, ezilinganayo ukuze zakheke, ezinobukhulu obusuka ku-10-30μm.
3. Isigaba sokupholisa: Izinga lokupholisa elihamba kancane elingu-≤5°C/min livimbela ukwethulwa kokucindezeleka okusha.

Idatha esekelayo:

• Izinga lokushisa le-annealing lithonya ngokuqondile usayizi wokusanhlamvu. Isibonelo, ku-250 ° C, izinhlamvu ezingaba ngu-15μm zifinyelelwa, okuholela kumandla okuqina we-280 MPa. Ukwenyusa izinga lokushisa libe ngu-300°C kwandisa okusanhlamvu ku-25μm, kwehlisa amandla ku-220 MPa.
• Isikhathi esifanele sokubamba sibalulekile. Ku-280°C, ukubamba amahora angu-3 kuqinisekisa ukuguqulwa kabusha kwekristalu okungaphezulu kuka-98%, njengoba kuqinisekiswe ukuhlaziya kwe-X-ray diffraction.

2. Izinto Ezithuthukisiwe Zokuhlanganisa: Ukunemba kanye Nokuvimbela I-oxidation

Ukuthungatha okusebenzayo kudinga amaziko akhethekile avikelwe ngegesi ukuze kuqinisekiswe ukusatshalaliswa kwezinga lokushisa okufanayo nokuvimbela ukugcotshwa kwe-oxidation:

1. Idizayini yesithando somlilo: Ukulawulwa kwezinga lokushisa okuzimele kwezindawo eziningi (isb., ukucushwa kwendawo eyisithupha) kuqinisekisa ukuhlukahluka kwezinga lokushisa kulo lonke ububanzi be-foil kuhlala ngaphakathi ku-±1.5°C.
2. I-Protective Atmosphere: Kwethulwa i-nitrogen ephezulu (≥99.999%) noma ingxube ye-nitrogen-hydrogen (3% -5% H₂) igcina amazinga e-oxygen engaphansi kuka-5 ppm, ivimbela ukwakheka kwama-oxide ethusi (ugqinsi lwengqimba ye-oxide <10 nm).
3. I-Conveyance System: Ukuthuthwa kwamarola angenayo ingcindezi kugcina ucwecwe oluthambile. Izithando zokushisa eziphakeme eziqondile zingasebenza ngesivinini esingafika kumamitha angu-120 ngomzuzu, namandla osuku angamathani angama-20 isithando somlilo ngasinye.

Ucwaningo lwesigameko: Iklayenti elisebenzisa isithando somlilo esingangenisi lithole i-oxidation ebomvuucwecwe lwethusiindawo engaphezulu (okuqukethwe komoya-mpilo kufika ku-50 ppm), okuholela kuma-burrs ngesikhathi sokucwiliswa. Ukushintshela esithandweni somlilo esivikelayo kubangele ukuhwaqamuka kwendawo (Ra) okungu-≤0.4μm kanye nesivuno esithuthukisiwe sokunamathisela sibe ngu-99.6%.

3. Ukuthuthukiswa kokusebenza: Kusuka “ku-Industrial Raw Material” kuya “ku-Functional Material”

I-foil yethusi ene-anealedikhombisa ukuthuthuka okubalulekile:

Lezi zithuthukisi zenza i-foil yethusi e-annealed ilungele:

1. Ama-Flexible Printed Circuits (FPCs): Ngobude obungaphezu kuka-20%, i-foil ikwazi ukumelana nemijikelezo yokugoba eguquguqukayo engaphezu kuka-100,000, ihlangabezana nezidingo zamadivayisi asongekayo.
2. Iziqoqi Zamanje Zebhethri Le-Lithium-Ion: Ama-foil athambile (HV<90) amelana nokuqhekeka ngesikhathi sokumbozwa kwe-electrode, futhi ama-foil angu-6μm azacile kakhulu agcina ukufana kwesisindo ngaphakathi kuka-±3%.
3. I-High-Frequency Substrates: Ubulukhuni bobuso obungaphansi kuka-0.5μm kunciphisa ukulahlekelwa kwesignali, kunciphisa ukulahlekelwa kokufaka ngo-15% ku-28 GHz.
4. Izinto Zokuvikela Ze-Electromagnetic: Ukusebenza kwe-101% IACS kuqinisekisa ukusebenza kahle kokuvikela okungenani okungu-80 dB ku-1 GHz.

4. I-CIVEN METAL: I-Pioneering Industry-Leading Annealing Technology

I-CIVEN METAL izuze ukuthuthuka okuningana kubuchwepheshe bokufaka i-annealing:

1. Intelligent Temperature Control: Ukusebenzisa ama-algorithms e-PID anempendulo ye-infrared, ukufeza ukunemba kokulawula izinga lokushisa okungu-±1°C.
2. Ukuvalwa Okuthuthukisiwe: Izindonga zesithando somlilo ezinezingqimba ezimbili ezinesinxephezelo somfutho oguqukayo zinciphisa ukusetshenziswa kwegesi ngo-30%.
3. Grain Orientation Control: Ngokuhlanganisa ama-gradient annealing, akhiqiza ama-foil anobunzima obuhlukahlukene ngobude bawo, anomehluko wamandla wendawo afika ku-20%, afanele izingxenye ezinezigxivizo eziyinkimbinkimbi.

Ukuqinisekisa: I-RTF-3 ye-RTF-3 ye-RTF-3 ye-reverse-treated foil, post-annealing, iqinisekiswe amaklayenti ukuze isetshenziswe kuma-PCB asesiteshini se-5G, kunciphisa ukulahlekelwa kwe-dielectric ku-0.0015 ku-10 GHz futhi kukhuphula izinga lokudlulisela ngo-12%.

5. Isiphetho: Ukubaluleka Kwesu Lokunamathisela Ekukhiqizeni I-Copper Foil

I-Annealing ingaphezu kwenqubo "yokushisa-okupholile"; kuwukuhlanganiswa okuyinkimbinkimbi kwesayensi yezinto zokwakha kanye nobunjiniyela. Ngokukhohlisa izici ze-microstructural ezifana nemingcele yokusanhlamvu nokugudluzwa,ucwecwe lwethusiizinguquko ezisuka “ekusebenzeni nzima” ukuya esimweni “esisebenzayo,” okusekela intuthuko kwezokuxhumana kwe-5G, izimoto zikagesi, nobuchwepheshe obugqokekayo. Njengoba izinqubo zokuhlanganisa zithuthukela ekuhlakanipheni okukhulu nasekuqhubekeni phambili—njengokuthuthukiswa kwe-CIVEN METAL kwezithando ze-hydrogen ezinciphisa ukukhishwa kwe-CO₂ ngo-40%—ucwecwe lwethusi olugoqiwe lulungele ukuvula amandla amasha ekusetshenzisweni okuphambili.
