Annealing Rolled Copper Foil: Ho notlolla Ts'ebetso e Ntlafetseng bakeng sa Likopo tse Tsoetseng Pele

Liindastering tsa theknoloji e phahameng tse kang tlhahiso ea lisebelisoa tsa elektronike, matla a tsosolositsoeng, le sefofane,foil ea koporo e kentsoengke ea bohlokoa ka lebaka la ho sebetsa ha eona hantle, ho fokola le ho boreleli. Leha ho le joalo, ntle le ho kolobisoa hantle, foil ea koporo e kolobisitsoeng e ka ba le bothata ba ho thatafala ha mosebetsi le khatello e setseng, e fokotsang tšebeliso ea eona. Annealing ke ts'ebetso ea bohlokoa e ntlafatsang sebopeho sa microstructure eafoil ea koporo, e ntlafatsang thepa ea eona bakeng sa likopo tse batlang. Sengoliloeng sena se shebisisa melao-motheo ea annealing, phello ea eona ts'ebetsong ea thepa, le ho tšoaneleha ha eona bakeng sa lihlahisoa tse fapaneng tsa maemo a holimo.

1. The Annealing Process: Transforming Microstructure for Superior Properties

Nakong ea ts'ebetso ea ho roala, likristale tsa koporo lia hatelloa le ho phahamisoa, ho theha sebopeho sa fibrous se tletseng ho kheloha le khatello ea kelello e setseng. Ho thatafala ha mosebetsi ona ho fella ka ho thatafala ho eketsehileng, ho fokotsa ductility (e telele ea 3% -5% feela), le ho fokotseha hanyenyane ha conductivity ho hoo e ka bang 98% IACS (International Annealed Copper Standard). Annealing e rarolla mathata ana ka tatelano e laoloang ea "heating-holding-cooling":

1. Mokhahlelo oa ho futhumatsa: Thefoil ea koporoe futhumatsoa ho mocheso oa eona oa recrystallization, hangata pakeng tsa 200-300 ° C bakeng sa koporo e hloekileng, ho kenya tšebetsong motsamao oa athomo.
2. Ho tšoara Mokhahlelo: Ho boloka mocheso ona ka lihora tse 2-4 ho lumella lijo-thollo tse sothehileng hore li senyehe, 'me lijo-thollo tse ncha, tse lekanang le tsona li thehoe, ka boholo ba 10-30μm.
3. Mokhahlelo oa ho Pholisa: Tekanyo e liehang ea ho pholile ea ≤5 ° C / min e thibela ho kenngoa ha khatello e ncha.

Lintlha tse tšehetsang:

• Anealing mocheso o ama ka ho toba boholo ba lijo-thollo. Ka mohlala, ka 250 ° C, lijo-thollo tse ka bang 15μm li finyelloa, e leng se hlahisang matla a matla a 280 MPa. Ho eketsa mocheso ho 300 ° C ho holisa lijo-thollo ho 25μm, ho fokotsa matla ho 220 MPa.
• Nako e nepahetseng ea ho boloka e bohlokoa. Ho 280 ° C, ho ts'oara lihora tse 3 ho netefatsa ho feta 98% recrystallization, joalo ka ha ho netefalitsoe ke tlhahlobo ea X-ray diffraction.

2. Lisebelisoa tse Tsoetseng Pele tsa Anealing: Precision and Oxidation Prevention

Ho kenngoa ka katleho ho hloka libopi tse khethehileng tse sirelelitsoeng ka khase ho netefatsa hore mocheso o ajoa ka mokhoa o ts'oanang le ho thibela oxidation:

1. Moqapi oa Sebōpi: Taolo ea mocheso e ikemetseng ea libaka tse ngata (mohlala, tlhophiso ea libaka tse tšeletseng) e netefatsa phapang ea mocheso ho pholletsa le bophara ba foil e lula ka har'a ± 1.5°C.
2. Sepakapaka se Sireletsang: Ho hlahisa naetrojene e hloekileng (≥99.999%) kapa motsoako oa nitrogen-hydrogen (3% -5% H₂) o boloka maemo a oksijene ka tlase ho 5 ppm, ho thibela ho thehoa ha li-oxide tsa koporo (oxide layer thickness <10 nm).
3. Tsamaiso ea Tsamaiso: Lipalangoang tse se nang tsitsipano tsa lirolara li boloka foil e bataletse. Libōpi tse tsoetseng pele tse otlolohileng li ka sebetsa ka lebelo la ho fihla ho limithara tse 120 ka motsotso, ka matla a letsatsi le letsatsi a lithane tse 20 ka sebōpi ka seng.

Thuto-pale: Moreki ea sebelisang sebopi se sa chesehang sa khase o ile a fumana oxidation e khubelu holim'afoil ea koporobokaholimo (litekanyo tsa oksijene ho fihla ho 50 ppm), tse lebisang ho li-burrs nakong ea etching. Ho fetohela sebōping sa sepakapaka se sireletsang ho ile ha fella ka ho rarahana holimo (Ra) ea ≤0.4μm le lihlahisoa tse ntlafetseng tsa etching ho 99.6%.

3. Ntlafatso ea Ts'ebetso: Ho tloha ho "Industrial Raw Material" ho ea ho "Functional Material"

Anealed koporo foile bonts'a lintlafatso tse kholo:

Lintlafatso tsena li etsa hore foil ea koporo e annealed e be e loketseng bakeng sa:

1. Flexible Printed Circuits (FPCs): Ka bolelele bo fetang 20%, foil e mamella lipotoloho tse feto-fetohang tse fetang 100,000, e fihlela litlhoko tsa lisebelisoa tse phuthoang.
2. Babokelli ba Hona Joale Ba Battery ea Lithium-Ion: Li-foil tse bonolo (HV <90) li hanela ho phunyeha nakong ea ho roala ha electrode, 'me li-foil tse tšesaane tsa 6μm li boloka boima ba 'mele ka hare ho ± 3%.
3. Li-Substrates tsa Maqhubu a Phahameng: Bokhopo bo ka tlase ho 0.5μm bo fokotsa tahlehelo ea matšoao, bo fokotsa tahlehelo ea ho kenya ka 15% ho 28 GHz.
4. Lisebelisoa tsa Ts'ireletso ea Motlakase: Conductivity ea 101% IACS e netefatsa katleho ea tšireletso ea bonyane 80 dB ho 1 GHz.

4. CIVEN METAL: Theknoloji ea Bopula-maliboho ea Indasteri e Eteletseng Pele ea Annealing

CIVEN METAL e fihletse likhatelopele tse 'maloa ho theknoloji ea annealing:

1. Taolo ea Mocheso e Bohlale: Ho sebelisa li-algorithms tsa PID ka maikutlo a infrared, ho finyella ho nepahala ha taolo ea mocheso oa ± 1 ° C.
2. Tiiso e Matlafalitsoeng: Mabota a sebōpi a nang le mats'eliso a khatello a matla a fokotsa tšebeliso ea khase ka 30%.
3. Taolo ea Boithuto ba lijo-thollo: Ka gradient annealing, ho hlahisa li-foil tse nang le bothata bo sa tšoaneng ho latela bolelele ba tsona, tse nang le phapang ea matla a sebakeng seo ho fihla ho 20%, tse loketseng likarolo tse thata tsa setempe.

Netefatso: CIVEN METAL's RTF-3 reverse-treated foil, post-annealing, e tiisitsoe ke bareki bakeng sa tšebeliso ea li-PCB tsa setsi sa 5G, ho fokotsa tahlehelo ea dielectric ho 0.0015 ho 10 GHz le ho eketsa litekanyetso tsa phetisetso ka 12%.

5. Qetello: Bohlokoa ba Leano la ho Anehela ka Tlhahiso ea Lesela la Koporo

Annealing ke ntho e fetang feela "mocheso o pholileng"; ke kopanyo e rarahaneng ea mahlale a thepa le boenjiniere. Ka ho laola likarolo tsa microstructural joalo ka meeli ea lijo-thollo le li-dilocation,foil ea koporoliphetoho ho tloha "mosebetsing o thata" ho ea sebakeng se "sebetsang", se tšehetsang tsoelo-pele litabeng tsa puisano tsa 5G, likoloi tsa motlakase, le theknoloji e aparoang. Ha lits'ebetso tsa annealing li ntse li tsoela pele ho ea bohlaleng bo boholo le bo tsitsitseng - joalo ka nts'etsopele ea CIVEN METAL ea libopi tsa haedrojene tse fokotsang tlhahiso ea CO₂ ka 40% - foil ea koporo e kolobisitsoeng e ikemiselitse ho bula menyetla e mecha lits'ebetsong tse tsoetseng pele.
