Chojambula chamkuwamankhwala makamaka ntchito lithiamu batire makampani, mafakitale a radiatorndi makampani a PCB.
1.Electro yoyikidwa mkuwa (ED copper foil) imatanthawuza zojambula zamkuwa zopangidwa ndi electrodeposition. Kupanga kwake ndi njira ya electrolytic. Chodzigudubuza cha cathode chidzayamwa ayoni amkuwa achitsulo kuti apange zojambulazo za electrolytic yaiwisi. Pamene cathode roller imazungulira mosalekeza, zojambulazo zaiwisi zomwe zimapangidwira zimatengedwa mosalekeza ndikupukuta pa chogudubuza. Kenako amatsukidwa, kuumitsa, ndi kuikidwa mu mpukutu wa zojambulazo zaiwisi.
2.RA, Chojambula chamkuwa chopukutira, chimapangidwa pokonza miyala yamkuwa kukhala zitsulo zamkuwa, kenako pickling ndi degreasing, ndi mobwerezabwereza kutentha kugudubuza ndi calendering pa kutentha pamwamba pa 800 ° C.
3.HTE, mkulu kutentha elongation elekitirodi waikamo mkuwa zojambulazo, ndi zojambulazo mkuwa kuti amakhala elongation kwambiri pa kutentha kwambiri (180 ℃). Pakati pawo, elongation wa 35μm ndi 70μm wandiweyani mkuwa zojambulazo pa kutentha (180 ℃) ayenera anakhalabe pa oposa 30% ya elongation firiji. Amatchedwanso HD copper zojambulazo (high ductility copper foil).
4.RTF, Chojambula chamkuwa chosinthidwa, chomwe chimatchedwanso reverse copper foil, chimathandizira kumamatira ndikuchepetsa kukhwinyata powonjezera zokutira zinazake za utomoni pamtunda wonyezimira wa chojambula chamkuwa cha electrolytic. Nthawi zambiri, makulidwe ake ndi 2-4um. Mbali ya zojambulazo zamkuwa zomwe zimamangiriridwa ku utomoni wosanjikiza zimakhala ndi ukali wochepa kwambiri, pamene mbali yolimba ya zojambulazozo imayang'ana kunja. Chojambula chochepa cha mkuwa cha laminate chimathandiza kwambiri kupanga mapangidwe abwino a dera lamkati, ndipo mbali yowopsya imatsimikizira kumamatira. Pamene malo otsika kwambiri amagwiritsidwa ntchito pazidziwitso zapamwamba, mphamvu zamagetsi zimakhala bwino kwambiri.
5.DST, pawiri mbali mankhwala mkuwa zojambulazo, roughening onse pamalo osalala ndi akhakula. Cholinga chachikulu ndi kuchepetsa ndalama ndi kupulumutsa mkuwa pamwamba mankhwala ndi browning masitepe pamaso lamination. Choyipa chake ndi chakuti pamwamba pa mkuwa sichitha kukanda, ndipo zimakhala zovuta kuchotsa kuipitsidwako kamodzi koipitsidwa. Ntchito ikucheperachepera pang'onopang'ono.
6.LP, chojambula chotsika chamkuwa. Zojambula zina zamkuwa zokhala ndi mbiri yapansi zimaphatikizapo zojambulazo za VLP zamkuwa (zojambula zochepa kwambiri zamkuwa), zojambula zamkuwa za HVLP (High Volume Low Pressure), HVLP2, ndi zina zotero. opanda makhiristo a columnar, ndipo ndi makhiristo a lamellar okhala ndi m'mphepete mwathyathyathya, omwe amathandizira kufalitsa ma siginecha.
7.RCC, zojambulazo zopangidwa ndi utomoni zamkuwa, zomwe zimadziwikanso kuti zojambulazo zamkuwa, zomatira zomata zamkuwa. Ndi chojambula chopyapyala chamkuwa cha electrolytic (makhuthala nthawi zambiri amakhala ≦18μm) yokhala ndi guluu umodzi kapena ziwiri za guluu wopangidwa mwapadera (gawo lalikulu la utomoni nthawi zambiri ndi utomoni wa epoxy) wokutidwa pamwamba pa roughened, ndipo zosungunulira zimachotsedwa poyanika mkati. uvuni, ndi utomoni amakhala theka-anachiritsidwa B siteji.
8.UTF, chojambula chamkuwa chowonda kwambiri, chimatanthawuza zojambulazo zamkuwa zokhala ndi makulidwe osakwana 12μm. Chodziwika kwambiri ndi zojambula zamkuwa zomwe zili pansi pa 9μm, zomwe zimagwiritsidwa ntchito popanga matabwa ozungulira osindikizidwa okhala ndi mabwalo abwino ndipo nthawi zambiri amathandizidwa ndi chonyamulira.
