1. Isingeniso Se-Copper Foil
Ucwecwe lwethusi (ucwecwe lwethusi): uhlobo lwempahla ye-cathode electrolytic, ucwecwe lwensimbi oluncane, oluqhubekayo olufakwe kungqimba oluyisisekelo lwebhodi lesifunda, olusebenza njengomqhubi we-PCB. Inamathela kalula kungqimba lwe-insulating, yamukela isendlalelo sokuzivikela esiphrintiwe, futhi yakha iphethini yesifunda ngemva kokugqwala. Ukuhlolwa kwesibuko sethusi (ukuhlolwa kwesibuko sethusi): ukuhlolwa kokugqwala kwe-flux, kusetshenziswa ifilimu ye-vacuum deposition epuleti lengilazi.
I-foil yethusi yenziwe ngethusi kanye nengxenye ethile yezinye izinsimbi. I-copper foil ngokuvamile ine-foil engu-90 kanye ne-foil engu-88, okusho ukuthi, okuqukethwe kwethusi kungu-90% no-88%, futhi ubukhulu bungu-16 * 16cm. I-copper foil iyinto esetshenziswa kakhulu yokuhlobisa. Okufana nalokhu: amahhotela, amathempeli, izithombe zikaBuddha, izimpawu zegolide, ama-tile mosaics, imisebenzi yezandla, njll.
2. Izici zomkhiqizo
I-copper foil inezici eziphansi ze-oxygen engaphezulu futhi ingaxhunywa kuma-substrates ahlukahlukene, njengezinsimbi, izinto zokuvikela ukushisa, njll., futhi inobubanzi obubanzi bokushisa. Isetshenziswa kakhulu ekuvikelweni kwe-electromagnetic kanye ne-antistatic. I-foil yethusi eqhutshwayo ibekwe phezu kwe-substrate futhi ihlanganiswe ne-substrate yensimbi, ene-conductivity enhle kakhulu futhi inikeza umphumela wokuzivikela we-electromagnetic. Ingahlukaniswa ngokuthi: i-self-adhesive copper foil, i-foil yethusi eqhutshwa kabili, i-foil eyodwa-conducting yethusi, njll.
I-foil yethusi yezinga le-elekthronikhi (ukuhlanzeka okungaphezu kuka-99.7%, ukujiya okungu-5um-105um) kungenye yezinto eziyisisekelo embonini ye-electronics. Ukuthuthukiswa okusheshayo kwemboni yolwazi lwe-elekthronikhi, ukusetshenziswa kwe-foil yethusi ebangeni le-elekthronikhi kuyanda, futhi imikhiqizo isetshenziswa kabanzi kumshini wokubala wezimboni, imishini yokuxhumana, imishini ye-QA, amabhethri e-lithium-ion, amathelevishini avamile, amarekhodi evidiyo, abadlali be-CD, amakhophi, izingcingo, isimo somoya, izingxenye ze-elekthronikhi zezimoto, ama-game consoles, njll. Izimakethe zasekhaya nezangaphandle zinesidingo esikhulayo sephepha lethusi le-electronic grade, ikakhulukazi ucwecwe lwethusi lwe-elekthronikhi olusebenza kakhulu. Izinhlangano ezifanele zochwepheshe zibikezela ukuthi ngo-2015, isidingo sasekhaya saseShayina sephepha le-electronic grade copper sizofinyelela amathani angu-300,000, futhi iChina izoba isizinda sokukhiqiza esikhulu kunazo zonke emhlabeni samabhodi esekethe aphrintiwe namafoyili ethusi. Imakethe ye-elekthronikhi ye-copper foil, ikakhulukazi ucwecwe olusebenza kahle kakhulu, inethemba. .
3. ukunikezwa komhlaba wonke kwefoyili yethusi
Ucwecwe lwethusi lwezimboni lungahlukaniswa ngokujwayelekile lube izigaba ezimbili: ucwecwe lwethusi olugoqiwe (ucwecwe lwethusi lwe-RA) kanye nocwecwe lwethusi lwesixazululo sephoyinti (ucwecwe lwethusi lwe-ED). Phakathi kwazo, i-foil yethusi egoqiwe ine-ductility enhle nezinye izici, ezisetshenziswa ekuqaleni kwenqubo yebhodi elithambile. I-copper foil, ne-electrolytic copper foil inenzuzo yezindleko eziphansi zokukhiqiza kune-foil yethusi egoqiwe. Njengoba ucwecwe lwethusi olugoqiwe luyinto ebalulekile yokusetshenziswa kwamabhodi aguquguqukayo, ukuthuthukiswa kwezici kanye noshintsho lwentengo yefoyili yethusi egoqiwe kunomthelela othile embonini yebhodi eguquguqukayo.
Njengoba kunabakhiqizi abambalwa be-foil yethusi egoqiwe, futhi ubuchwepheshe busezandleni zabanye abakhiqizi, amakhasimende anezinga eliphansi lokulawula amanani kanye nokunikezwa. Ngakho-ke, ngaphandle kokuthinta ukusebenza komkhiqizo, i-electrolytic copper foil isetshenziswa esikhundleni sokugoqa i-Copper foil iyisisombululo esingaba khona. Kodwa-ke, uma izici ezibonakalayo zecwecwe le-copper ngokwalo zizothinta izici ezihlabayo eminyakeni embalwa ezayo, ukubaluleka kocwecwe lwethusi olugoqiwe kuzokwanda futhi emikhiqizweni emincane noma emincane, kanye nemikhiqizo yamafrikhwensi aphezulu ngenxa yokucatshangelwa kokuxhumana ngocingo.
Kunezithiyo ezimbili ezinkulu ekukhiqizeni ucwecwe lwethusi olugoqiwe, izithiyo zensiza kanye nezithiyo zobuchwepheshe. Umgoqo wezinsiza ubhekisela esidingweni sezinto zokusetshenziswa zethusi ukuze zisekele ukukhiqizwa kwephepha lethusi eligoqiwe, futhi kubaluleke kakhulu ukusebenzisa izinsiza. Ngakolunye uhlangothi, izithiyo zobuchwepheshe zidikibalisa abasanda kungena abasha. Ngaphezu kobuchwepheshe be-calendering, ukwelashwa kwendawo noma ubuchwepheshe bokwelashwa kwe-oxidation nakho kuyasetshenziswa. Amafekthri amaningi amakhulu emhlabeni jikelele anamalungelo obunikazi obuchwepheshe obuningi kanye nobuchwepheshe obubalulekile ethi Know How, okwandisa izithiyo zokungena. Uma abasanda kuhlanganyela besebenza ngemva kokuvuna nokukhiqiza, bavinjelwa izindleko zabakhiqizi abakhulu, futhi akulula ukujoyina ngempumelelo imakethe. Ngakho-ke, i-foil yethusi egoqwe emhlabeni wonke isengeyemakethe ngokukhethekile okuqinile.
3. ukuthuthukiswa kwe-foil yethusi
Icwecwe le-Copper ngesiNgisi i-electrodepositedcopperfoil, into ebalulekile ekwenzeni i-copper clad laminate (CCL) kanye nebhodi lesifunda eliphrintiwe (PCB). Ekuthuthukisweni okusheshayo kwanamuhla kwemboni yolwazi lwe-elekthronikhi, i-electrolytic copper foil ibizwa ngokuthi: “inethiwekhi ye-neural” yesiginali yomkhiqizo we-elekthronikhi kanye nokudluliswa kwamandla nokuxhumana. Kusukela ngo-2002, inani lokukhiqiza lamabhodi wesifunda aphrintiwe e-China liye ladlula indawo yesithathu emhlabeni, futhi ama-laminates e-copper clad, i-substrate material ye-PCBs, nawo abe ngumkhiqizi wesithathu ngobukhulu emhlabeni. Ngenxa yalokho, imboni ye-electrolytic copper foil yaseShayina ithuthuke ngokugxumagxuma kanye nemingcele eminyakeni yamuva nje. Ukuze siqonde futhi siqonde isikhathi esidlule nesamanje somhlaba kanye nokuthuthukiswa kwemboni yensimbi yethusi ye-electrolytic yaseChina, futhi sibheke ngabomvu ikusasa, ochwepheshe be-China Epoxy Resin Industry Association babuyekeze ukuthuthuka kwayo.
Ngokombono womnyango wokukhiqiza kanye nokuthuthukiswa kwemakethe yemboni ye-electrolytic ye-copper foil, inqubo yayo yokuthuthukiswa ingahlukaniswa ngezikhathi ezintathu ezinkulu zokuthuthukiswa: i-United States yasungula ibhizinisi lokuqala lomhlaba le-copper foil kanye nesikhathi lapho imboni ye-electrolytic copper foil yaqala khona; Ucwecwe lwethusi lwaseJapan Isikhathi lapho amabhizinisi elawula ngokugcwele imakethe yomhlaba; isikhathi lapho umhlaba uhlukaniswe ngezigaba eziningi ukuze uqhudelane ngemakethe.
