I-Anealing Copper Foil: Ukuvula iNtsebenzo eYongezelelweyo kwii-Applications eziPhezulu

Kumashishini obuchwepheshe obuphezulu njengokwenza izinto zombane, amandla avuselelekayo, kunye ne-aerospace,ifoyile yobhedu esongwayoixabiseke kakhulu ngenxa yokuqhuba kakuhle kwayo, ukuthambile, kunye nomphezulu ogudileyo. Nangona kunjalo, ngaphandle kwe-annealing eyiyo, ifoyile yobhedu esongiweyo inokubandezeleka ngenxa yokuqina komsebenzi kunye noxinzelelo olushiyekileyo, inciphisa ukusetyenziswa kwayo. I-Anealing yinkqubo ebalulekileyo ephucula i-microstructure yeifoyile yobhedu, iphucula iipropati zayo kwizicelo ezifunayo. Eli nqaku lijonge kwimigaqo yokucoca, impembelelo yayo ekusebenzeni kwezinto, kunye nokufaneleka kwayo kwiimveliso ezahlukeneyo eziphezulu.

1. Inkqubo yokuHlola: Ukuguqula iMicrostructure kwiiPropati eziPhezulu

Ngethuba lenkqubo yokuqengqeleka, iikristale zethusi zixinzelelwe kwaye zide, zenze isakhiwo se-fibrous esizaliswe ngokuchithwa kunye noxinzelelo oluseleyo. Lo msebenzi unzima uphumela ekukhuleni kobunzima, ukunciphisa i-ductility (i-elongation ye-3% -5%) kuphela, kunye nokuncipha okuncinci kwi-conductivity malunga ne-98% ye-IACS (i-International Annealed Copper Standard). I-Anealing ijongana nale miba ngolandelelwano olulawulwayo “lokubamba-ukupholisa”:

1. Isigaba sokufudumeza: Iifoyile yobheduifudunyezwa kwiqondo lobushushu bayo, phakathi kwe-200-300 ° C yobhedu olusulungekileyo, ukwenza intshukumo yeathomu isebenze.
2. Isigaba sokubamba: Ukugcina lo bushushu kwiiyure ezingama-2-4 kuvumela iinkozo ezigqwesileyo ukuba zibole, kunye nentsha, i-equiaxed grains ukuba ifake, kunye nobukhulu obuvela kwi-10-30μm.
3. Isigaba sokupholisa: Isantya sokupholisa esicothayo se-≤5 ° C / min sithintela ukuqaliswa koxinzelelo olutsha.

Idatha exhasayo:

• Ubushushu be-anealing buchaphazela ngokuthe ngqo ubungakanani beenkozo. Ngokomzekelo, kwi-250 ° C, iinkozo ezimalunga ne-15μm zifezekisiwe, okukhokelela kumandla obunzima be-280 MPa. Ukwandisa izinga lokushisa ukuya kwi-300 ° C kwandisa iinkozo ukuya kwi-25μm, ukunciphisa amandla kwi-220 MPa.
• Ixesha elifanelekileyo lokubamba libalulekile. Kwi-280 ° C, ukubamba kweeyure ze-3 kuqinisekisa ngaphezu kwe-98% ye-recrystallization, njengoko kuqinisekiswe uhlalutyo lwe-X-ray diffraction.

2. Izixhobo eziPhezulu zokuHlola: Ukuchaneka kunye noThintelo lwe-Oxidation

Ukufunxa okusebenzayo kufuna iziko ezikhethekileyo ezikhuselwe ngegesi ukuqinisekisa ukuhanjiswa kwamaqondo afanayo kunye nokuthintela i-oxidation:

1. Uyilo lwesithando somlilo: Ulawulo lweqondo lobushushu oluzimeleyo lwezowuni ezininzi (umzekelo, ubumbeko lwezowuni emithandathu) luqinisekisa ukuguquguquka kobushushu kububanzi befoyile buhlala bungaphakathi kwe ±1.5°C.
2. Umoya okhuselayo: Ukwazisa i-nitrogen ephezulu ecocekileyo (≥99.999%) okanye i-nitrogen-hydrogen mix (3% -5% H₂) igcina amanqanaba e-oksijini ngaphantsi kwe-5 ppm, ukukhusela ukubunjwa kwee-oxides zethusi (ubukhulu be-oxide layer <10 nm).
3. Inkqubo yoHambo: I-tension-free roller transport igcina i-foil flatness. Iifurnas eziphucukileyo ezithe nkqo zinokusebenza ngesantya ukuya kuthi ga kwi-120 yeemitha ngomzuzu, ezinomthamo wemihla ngemihla weetoni ezingama-20 kwiziko ngalinye.

Into yokuphonononga: Umxhasi osebenzisa iziko lokufunxa irhasi engeyiyo inert uye wafumana oxidation ebomvuifoyile yobheduumphezulu (umxholo weoksijini ukuya kuthi ga kwi-50 ppm), ekhokelela kwi-burrs ngexesha lokubetha. Ukutshintshela kwisithando somoya esikhuselayo kubangele ubuninzi bomhlaba (Ra) we-≤0.4μm kunye nokuphucula isivuno se-etching kwi-99.6%.

3. Ukomelezwa kokuSebenza: Ukusuka “kwiMpathi ekrwada ye-Industrial” ukuya “kwiMathiriyeli eSebenzayo”

I-foil yobhedu ene-anealedibonisa uphuculo olubalulekileyo:

Ezi zixhasi zenza ifoyile yobhedu ene-anealed ilungele:

1. IiSekethe eziShicileleyo eziFlebileyo (FPCs): Ngobude obungaphezulu kwe-20%, ifoyile imelana nemijikelo yokugoba eguquguqukayo engaphezu kwe-100,000, ihlangabezana neemfuno zezixhobo ezisongekayo.
2. Abaqokeleli bangoku bebhetri yeLithium-Ion: Iifolthi ezithambileyo (HV<90) zixhathisa ukuqhekeka ngexesha lokutyalwa kwe-electrode, kunye ne-ultra-thin 6μm iifolthi zigcina ubunzima obungaguqukiyo ngaphakathi ± 3%.
3. IiSubstrates eziPhakamileyo: Uburhabaxa bomphezulu obungaphantsi kwe-0.5μm bunciphisa ukulahleka komqondiso, ukunciphisa ilahleko yokufaka nge-15% kwi-28 GHz.
4. Izinto zokuKhusela i-Electromagnetic: I-Conductivity ye-101% IACS iqinisekisa ukusebenza kokukhusela ubuncinane be-80 dB kwi-1 GHz.

4. I-CIVEN METAL: I-Pioneering Industry-Lead Linealing Technology

I-CIVEN METAL ifezekise uphuculo oluninzi kwitekhnoloji yokudibanisa:

1. Ulawulo lobushushu obukrelekrele: Ukusebenzisa i-algorithms ye-PID ngempendulo ye-infrared, ukufezekisa ulawulo lweqondo lokushisa oluchanekileyo ± 1 ° C.
2. Utywino olongezelelweyo: Iindonga zesithando se-double-layer kunye nembuyekezo yoxinzelelo oluguquguqukayo lunciphisa ukusetyenziswa kwegesi ngama-30%.
3. Ulawulo lokuqhelaniswa neenkozo: Ngokudibanisa i-gradient annealing, ukuvelisa iifoyile ezinobunzima obahluka-hlukeneyo ngobude bazo, ezinomahluko wamandla engingqi ukuya kuthi ga kwi-20%, ezifanelekileyo kumalungu antsonkothileyo anesitampu.

Ukuqinisekiswa: I-CIVEN METAL ye-RTF-3 i-reverse-treated foil, i-post-annealing, iqinisekisiwe ngabaxhasi bokusetyenziswa kwi-PCB yesiseko se-5G, ukunciphisa ilahleko ye-dielectric kwi-0.0015 kwi-10 GHz kunye nokunyusa izinga lokuhambisa nge-12%.

5. Isiphelo: Ukubaluleka koBuchule boKuhlonyelwa kwiMveliso yeFoil yeCopper

I-Anealing ingaphezulu kwenkqubo "epholileyo yobushushu"; ludibaniso oluntsonkothileyo lwenzululwazi yemathiriyeli kunye nobunjineli. Ngokulawula iimpawu ze-microstructural ezifana nemida yeenkozo kunye nokuchithwa,ifoyile yobheduutshintsho olusuka "kumsebenzi onzima" ukuya kwimeko "esebenzayo", exhasa ukuqhubela phambili kwi-5G yonxibelelwano, izithuthi zombane, kunye nobuchwepheshe obunxitywayo. Njengoko iinkqubo ze-annealing ziguqukela kubukrelekrele obukhulu kunye nozinzo-ezifana nophuhliso lwe-CIVEN METAL lweziko ezisebenza nge-hydrogen ezinciphisa ukukhutshwa kwe-CO₂ nge-40%-ifoyile yobhedu eqengqelekisiweyo ilungele ukuvula amandla amatsha kwizicelo ezibukhali.
