I-Annealing Rolled Copper Foil: Ukuvula Ukusebenza Okuphuculweyo Kwezicelo Eziphambili

Kwimizi-mveliso yobuchwepheshe obuphezulu efana nokuvelisa izinto ze-elektroniki, amandla avuselelekayo, kunye neenqwelo-moya,ifoyile yobhedu eqengqiweyoixatyiswa kakhulu ngenxa yokuqhuba kwayo kakuhle, ukuguguleka kwayo, kunye nomphezulu wayo ogudileyo. Nangona kunjalo, ngaphandle kokuqhoboshelwa ngokufanelekileyo, i-foil yobhedu egoqiweyo inokuba nengxaki yokuqina komsebenzi kunye noxinzelelo olushiyekileyo, nto leyo ethintela ukusetyenziswa kwayo. Ukuqhoboshelwa yinkqubo ebalulekileyo ephucula ulwakhiwo lwayo oluncinciifoyile yobhedu, ukuphucula iipropati zayo ukuze zisetyenziswe ngendlela efunwayo. Eli nqaku liza kujonga imigaqo yokufakelwa kwe-annealing, impembelelo yayo ekusebenzeni kwezinto, kunye nokufaneleka kwayo kwiimveliso ezahlukeneyo zexabiso eliphezulu.

1. Inkqubo yokuNyula: Ukuguqula ulwakhiwo lweMicros ukuze lube ziiPropati eziPhezulu

Ngexesha lenkqubo yokuqengqeleka, iikristale zobhedu ziyacinezelwa kwaye zandiswe, nto leyo eyenza isakhiwo esineefayibha ezizaliswe kukwahlukana kunye noxinzelelo olushiyekileyo. Oku kuqina komsebenzi kubangela ukwanda kobunzima, ukuncipha kokuguquguquka (ukwandiswa kwe-3%-5%) kuphela, kunye nokwehla okuncinci kokuqhuba ukuya kwi-98% ye-IACS (i-International Annealed Copper Standard). I-Annealing ijongana nale micimbi ngolandelelwano olulawulwayo "lokubamba ubushushu-ukupholisa":

1. Isigaba sokufudumeza: Iifoyile yobheduifudunyezwa ukuya kubushushu bayo bokuphinda i-crystallization, ngesiqhelo phakathi kwama-200-300°C ukuze ifumane ubhedu olucocekileyo, ukuze isebenze intshukumo yeathomu.
2. Isigaba sokubamba: Ukugcina obu bushushu kangangeeyure ezi-2-4 kuvumela iinkozo ezijijekileyo ukuba zibole, kwaye iinkozo ezintsha, ezilinganayo, zenzeke, ezinobukhulu obuqala kwi-10-30μm.
3. Isigaba sokuPholisa: Isantya sokuphola esicothayo se-≤5°C/min sithintela ukungeniswa koxinzelelo olutsha.

Idatha exhasayo:

• Ubushushu obuncitshisiweyo buchaphazela ngokuthe ngqo ubungakanani beenkozo. Umzekelo, kwi-250°C, iinkozo ezimalunga ne-15μm ziyafumaneka, nto leyo ebangela amandla okutsalwa angama-280 MPa. Ukunyusa ubushushu ukuya kwi-300°C kwandisa iinkozo ukuya kwi-25μm, kunciphisa amandla ukuya kwi-220 MPa.
• Ixesha elifanelekileyo lokubamba libalulekile. Kwi-280°C, ukubamba iiyure ezi-3 kuqinisekisa ukuphinda kusetyenziswe ikristale ngaphezulu kwe-98%, njengoko kuqinisekiswe luhlalutyo lwe-X-ray diffraction.

2. Izixhobo zoQokelelo oluPhambili: Uthintelo lokuChaneka kunye nokuNqanda iOksijini

Ukufakelwa ngempumelelo kufuna izitofu ezikhethekileyo ezikhuselwe yigesi ukuqinisekisa ukusasazwa kobushushu obufanayo kunye nokuthintela i-oxidation:

1. Uyilo lweSithando somlilo: Ulawulo lobushushu oluzimeleyo oluneendawo ezininzi (umz., uqwalaselo lweendawo ezintandathu) luqinisekisa ukuba umahluko wobushushu kububanzi befoyile uhlala ngaphakathi kwe-±1.5°C.
2. Umoya oKhuselayo: Ukungenisa i-nitrogen ecocekileyo kakhulu (≥99.999%) okanye umxube we-nitrogen-hydrogen (3%-5% H₂) kugcina amanqanaba eoksijini engaphantsi kwe-5 ppm, okuthintela ukwakheka kwee-copper oxides (ubukhulu be-oxide layer <10 nm).
3. Inkqubo yoThutho: Uthutho lwerola olungenaxinzelelo lugcina i-foil ithambile. Ii-annealing furnitures eziphambili zingasebenza ngesantya esifikelela kwi-120 yeemitha ngomzuzu, kwaye umthamo wemihla ngemihla ziitoni ezingama-20 ngesi-furniture.

Into yokuphonononga: Umthengi osebenzisa isithando sokutshisa igesi esingangenisi mandla wafumana i-oxidation ebomvu kwiifoyile yobheduumphezulu (umxholo weoksijini ukuya kuthi ga kwi-50 ppm), nto leyo ekhokelela kwi-burrs ngexesha lokugrumba. Ukutshintshela kwi-atmosphere okhuselayo kubangele uburhabaxa bomphezulu (Ra) obuyi-≤0.4μm kunye nokuphucula isivuno sokugrumba ukuya kwi-99.6%.

3. Uphuculo Lokusebenza: Ukusuka “Kwizinto Ezingavuthwanga Zemizi-mveliso” ukuya “Kwizinto Ezisebenzayo”

Ifoyile yobhedu efakwe kwi-Annealedibonisa uphuculo olubalulekileyo:

Ezi zinto zongezayo zenza i-alnealed copper foil ilungele:

1. Iisekethe eziprintiweyo eziguquguqukayo (ii-FPC): Ngokwandiswa okungaphezulu kwama-20%, ifoyile imelana nemijikelo yokugoba engaphezu kwe-100,000, ihlangabezana neemfuno zezixhobo ezigoqekayo.
2. Abaqokeleli bangoku bebhetri yeLithium-Ion: Iifoyile ezithambileyo (HV<90) ziyamelana nokuqhekeka ngexesha lokugqunywa kwe-electrode, kwaye iifoyile ezibhityileyo kakhulu ze-6μm zigcina ubunzima buqinile ngaphakathi kwe-±3%.
3. Iisubstrates eziQhelekileyo kakhulu: Uburhabaxa bomphezulu obungaphantsi kwe-0.5μm kunciphisa ukulahleka kwesiginali, kunciphisa ukulahleka kokufakwa nge-15% kwi-28 GHz.
4. Izixhobo zokukhusela nge-electromagnetic: Ukuqhuba kwe-IACS eyi-101% kuqinisekisa ukusebenza kakuhle kokukhusela kwe-80 dB ubuncinane kwi-1 GHz.

4. I-CIVEN METAL: Itekhnoloji yokuQala i-Annealing ePhambili kwiShishini

I-CIVEN METAL iphumelele inkqubela phambili kwitekhnoloji yokufakela izinto ezingafunekiyo:

1. Ulawulo lobushushu olukrelekrele: Ukusebenzisa ii-algorithms ze-PID ezinempendulo ye-infrared, ukufikelela kulawulo lobushushu oluchanekileyo lwe-±1°C.
2. Utywino Oluphuculweyo: Iindonga zesithando somlilo ezineengqimba ezimbini ezinembuyekezo yoxinzelelo oluguquguqukayo zinciphisa ukusetyenziswa kwegesi ngama-30%.
3. Ulawulo lokuQhelaniswa kweeNkozo: Ngokusebenzisa i-gradient annealing, ukuvelisa iifoyile ezinobunzima obahlukeneyo kubude bazo, kunye nomahluko wamandla asekuhlaleni ukuya kuthi ga kwi-20%, ezifanelekileyo kwiindawo ezixineneyo ezinesitampu.

Ukuqinisekiswa: Ifoyile ye-RTF-3 ye-CIVEN METAL evuselelwe ngasemva, emva kokuqhoboshelwa, iqinisekiswe ngabathengi ukuba isetyenziswe kwi-PCB zesikhululo se-5G, nto leyo enciphisa ilahleko ye-dielectric ukuya kwi-0.0015 kwi-10 GHz kwaye yonyusa amazinga othumelo nge-12%.

5. Isiphelo: Ukubaluleka koBuchule bokuNgcwaba kwiMveliso yeFoyile yoCopper

Ukutsalwa kwe-Annealing kungaphezulu nje kwenkqubo "yokupholisa ubushushu"; kukuhlanganiswa okuntsonkothileyo kwesayensi yezinto kunye nobunjineli. Ngokulawula iimpawu zesakhiwo esincinci ezifana nemida yeenkozo kunye nokudilika,ifoyile yobheduutshintsho ukusuka kwimeko "enzima yokusebenza" ukuya kwimeko "esebenzayo", nto leyo exhasa uphuhliso kunxibelelwano lwe-5G, izithuthi zombane, kunye netekhnoloji enxitywayo. Njengoko iinkqubo zokukhupha umoya ziguqukela kubukrelekrele obukhulu kunye nokuzinza—njengophuhliso lwe-CIVEN METAL lwee-ovens ezisebenzisa i-hydrogen ezinciphisa ukukhutshwa kwe-CO₂ ngama-40%—i-copper foil egoqiweyo ikulungele ukuvula amandla amatsha kwizicelo zangoku.
