I-Annealing Rolled Copper Foil: Ukuvula Ukusebenza Okuthuthukisiwe Kwezinhlelo Zokusebenza Ezithuthukisiwe

Ezimbonini zobuchwepheshe obuphezulu njengokukhiqiza izinto zikagesi, amandla avuselelekayo, kanye nezindiza,i-foil yethusi egoqiweiyaziswa ngokuhambisa kwayo okuhle kakhulu, ukuguguleka, kanye nobuso obubushelelezi. Kodwa-ke, ngaphandle kokugoqwa okufanele, i-foil yethusi egoqiwe ingahlushwa ukuqina komsebenzi kanye nokucindezeleka okusele, okunciphisa ukusetshenziswa kwayo. Ukugoqwa kuyinqubo ebalulekile ethuthukisa isakhiwo sayo esincanei-foil yethusi, ithuthukisa izakhiwo zayo ukuze zisetshenziswe ngokuzikhandla. Lesi sihloko sigxila ezimisweni zokufaka i-annealing, umthelela wayo ekusebenzeni kwezinto ezibonakalayo, kanye nokufaneleka kwayo emikhiqizweni ehlukahlukene yekhwalithi ephezulu.

1. Inqubo Yokunamathela: Ukuguqula Isakhiwo Esincane Sezakhiwo Eziphakeme

Ngesikhathi senqubo yokugoqa, amakristalu ethusi ayacindezelwa futhi ande, okudala isakhiwo esinemicu egcwele ukuhlukana kanye nokucindezeleka okusele. Lokhu kuqina komsebenzi kuphumela ekuqineni okukhulu, ukuncipha kokuguquguquka (ukunwebeka okungu-3%-5%) kuphela, kanye nokwehla okuncane kokuqhuba ugesi kuya cishe ku-98% IACS (International Annealed Copper Standard). I-Annealing ibhekana nalezi zinkinga ngochungechunge olulawulwayo "lokubamba ukushisa-ukupholisa":

1. Isigaba Sokushisa: Ii-foil yethusiishiswa ekushiseni kwayo kokuphinda isetshenziswe, ngokuvamile phakathi kuka-200-300°C ukuze ithole ithusi elihlanzekile, ukuze kusebenze ukunyakaza kwama-athomu.
2. Isigaba Sokubamba: Ukugcina leli zinga lokushisa amahora angu-2-4 kuvumela okusanhlamvu okusontekile ukuthi kubole, kanye nokusanhlamvu okusha, okulinganayo, osayizi bako basukela ku-10-30μm.
3. Isigaba Sokupholisa: Izinga lokupholisa elihamba kancane elingu-≤5°C/min livimbela ukwethulwa kwezingcindezi ezintsha.

Idatha Esekelayo:

• Izinga lokushisa elincibilikayo lithinta ngqo usayizi wezinhlamvu. Isibonelo, ku-250°C, izinhlamvu ezingaba ngu-15μm ziyafinyelelwa, okuholela ekuqineni okunamandla okungu-280 MPa. Ukwandisa izinga lokushisa libe ngu-300°C kwandisa izinhlamvu zibe ngu-25μm, kunciphisa amandla abe ngu-220 MPa.
• Isikhathi esifanele sokubamba sibalulekile. Ku-280°C, ukubamba amahora amathathu kuqinisekisa ukuphinda kusetshenziswe kabusha kwekristalu okungaphezu kuka-98%, njengoba kuqinisekiswe ukuhlaziywa kwe-X-ray diffraction.

2. Imishini Yokunamathisela Ethuthukisiwe: Ukuvimbela Ukunemba Nokushiswa Kwe-Oxidation

Ukufakwa kwe-anneal okuphumelelayo kudinga izitofu ezikhethekile ezivikelwe ngegesi ukuqinisekisa ukusatshalaliswa kokushisa okufanayo nokuvimbela ukungcoliswa:

1. Umklamo Wesithando Somlilo: Ukulawulwa kokushisa okuzimele kwezindawo eziningi (isb., ukucushwa kwezindawo eziyisithupha) kuqinisekisa ukuthi ukushintshashintsha kokushisa kulo lonke ububanzi befoyili kuhlala ngaphakathi kuka-±1.5°C.
2. Isimo Esivikelayo: Ukwethula i-nitrogen ehlanzekile kakhulu (≥99.999%) noma ingxube ye-nitrogen-hydrogen (3%-5% H₂) kugcina amazinga omoya-mpilo engaphansi kuka-5 ppm, okuvimbela ukwakheka kwama-oxide ethusi (ubukhulu bengqimba ye-oxide <10 nm).
3. Uhlelo Lokuthutha: Ukuthuthwa kwe-roller okungenangcindezi kugcina i-foil ithambile. Izitofu ezithuthukisiwe zokufaka i-annealing zingasebenza ngesivinini esifinyelela kumamitha ayi-120 ngomzuzu, ngomthamo wansuku zonke wamathani angama-20 ngesitofu ngasinye.

Ucwaningo lwesigameko: Iklayenti elisebenzisa isithando somlilo esingenagesi esingenawo umoya lithole ukushiswa okubomvu ku-oxidationi-foil yethusiubuso (okuqukethwe komoya-mpilo kufika ku-50 ppm), okuholela kuma-burrs ngesikhathi sokusika. Ukushintshela esithandweni somoya esivikelayo kuholele ekubeni lukhuni kobuso (Ra) okungu-≤0.4μm kanye nokuthuthukiswa kokusika okuthuthukisiwe kwaba ngu-99.6%.

3. Ukuthuthukiswa Kokusebenza: Kusukela “Ezinto Ezingavuthiwe Zezimboni” Kuya “Ezinto Ezisebenzayo”

I-foil yethusi ehlanganisiwekukhombisa ukuthuthuka okuphawulekayo:

Lezi zithuthukisi zenza i-foil yethusi eqoshiwe ifaneleke kakhulu:

1. Amasekethe Aphrintiwe Aguquguqukayo (ama-FPC): Njengoba i-foil inwebeka ngaphezu kuka-20%, ikwazi ukumelana nemijikelezo yokugoba engaphezu kuka-100,000, ihlangabezana nezidingo zamadivayisi agoqekayo.
2. Abaqoqi Bamanje Bebhethri Le-Lithium-Ion: Ama-foil athambile (HV<90) amelana nokuqhekeka ngesikhathi sokumbozwa kwe-electrode, kanti ama-foil amancane kakhulu angu-6μm agcina isisindo siqinile ngaphakathi kuka-±3%.
3. Izingxenyana Ezivame Kakhulu: Ukungalungi komphezulu okungaphansi kuka-0.5μm kunciphisa ukulahleka kwesiginali, kunciphisa ukulahleka kokufakwa ngo-15% ku-28 GHz.
4. Izinto Zokuvikela Ama-electromagnetic: Ukuqhuba kwe-IACS okungu-101% kuqinisekisa ukusebenza kahle kokuvikela okungenani okungu-80 dB ku-1 GHz.

4. I-CIVEN METAL: Ubuchwepheshe Bokusungula I-Annealing Obuhamba Phambili Embonini

I-CIVEN METAL ifinyelele intuthuko eminingana kubuchwepheshe bokunamathisela:

1. Ukulawula Izinga Lokushisa Elihlakaniphile: Ukusebenzisa ama-algorithm e-PID anempendulo ye-infrared, kufinyelela ukunemba kokulawula izinga lokushisa okungu-±1°C.
2. Ukuvalwa Okuthuthukisiwe: Izindonga zesithando somlilo ezinezingqimba ezimbili ezinesinxephezelo sokucindezela okunamandla zinciphisa ukusetshenziswa kwegesi ngo-30%.
3. Ukulawulwa Kokuqondisa Okusanhlamvu: Ngokusebenzisa i-gradient annealing, ukukhiqiza ama-foil anobunzima obuhlukahlukene ngobude bawo, ngomehluko wamandla wendawo ofika ku-20%, afanele izingxenye eziyinkimbinkimbi ezigxiviziwe.

Ukuqinisekiswa: I-foil ye-RTF-3 ye-CIVEN METAL ehlungwe emuva, ngemuva kokuncibilikiswa, iqinisekiswe ngamakhasimende ukuthi isetshenziswe kuma-PCB esiteshi se-5G, okunciphisa ukulahleka kwe-dielectric kube ngu-0.0015 ku-10 GHz kanye nokwandisa amazinga okudlulisa ngo-12%.

5. Isiphetho: Ukubaluleka Kwamasu Kokunamathisela Ekukhiqizweni Kwe-Copper Foil

Ukuhlanganisa izinto kungaphezu kwenqubo "yokupholisa ukushisa"; kuwukuhlanganiswa okuyinkimbinkimbi kwesayensi yezinto zokwakha kanye nobunjiniyela. Ngokulawula izici zesakhiwo ezincane njengemingcele yokusanhlamvu kanye nokuhlukaniswa,i-foil yethusiizinguquko kusukela esimweni "esinzima" kuya esimweni "esisebenzayo", okusekela intuthuko kwezokuxhumana ze-5G, izimoto zikagesi, kanye nobuchwepheshe obugqokwayo. Njengoba izinqubo zokudonsa zithuthuka ziye ekuhlakanipheni okukhulu nasekuzinzeni—njengokuthuthukiswa kwe-CIVEN METAL kwezitofu ezisebenzisa i-hydrogen ezinciphisa ukukhishwa kwe-CO₂ ngo-40%—i-foil yethusi egoqiwe ilungele ukuvula amandla amasha ezinhlelweni zokusebenza ezisezingeni eliphezulu.
