1. Introduction to Copper Foil

Copper Foil (Copper Foil): He ʻano mea electrolytic cathode, he ʻeleʻele ʻeleʻele a hoʻomau i waiho ʻia ma ka papa kumu o ka papa kaapuni, e hana ana ma ke ʻano he alakaʻi o ka PCB. Hoʻopili maʻalahi ia i ka papa insulating, ʻae i ka papa pale i paʻi ʻia, a hana i ke ʻano kaapuni ma hope o ka ʻino. ʻO ka hoʻāʻo aniani keleawe (hōʻike aniani keleawe): kahi hoʻāʻo corrosion flux, me ka hoʻohana ʻana i kahi kiʻiʻoniʻoni maloʻo ma ka pā aniani.

Hana ʻia ke keleawe keleawe a me kekahi hapa o nā metala ʻē aʻe. ʻO ka pahu keleawe maʻamau he 90 foil a me 88 foil, ʻo ia hoʻi, ʻo ka ʻike keleawe he 90% a me 88%, a ʻo ka nui he 16 * 16cm. ʻO Copper foil ka mea hoʻonaninani nui loa. E like me: nā hōkele, nā luakini, nā kiʻi Buddha, nā hōʻailona gula, nā mosaics tile, nā mea hana lima, etc.

2. Nā hiʻohiʻona huahana

He haʻahaʻa haʻahaʻa nā hiʻohiʻona o ka oxygen i ka pahu keleawe a hiki ke hoʻopili ʻia i nā substrate like ʻole, e like me nā metala, nā mea insulating, a me nā mea ʻē aʻe, a he ākea ākea ākea. Hoʻohana nui ʻia i ka pale electromagnetic a me ka antistatic. Hoʻokomo ʻia ka pahu keleawe conductive ma ka ʻili o ka substrate a hui pū ʻia me ka substrate metala, nona ka conductivity maikaʻi loa a hāʻawi i ka hopena pale electromagnetic. Hiki ke hoʻokaʻawale ʻia i: paʻi keleawe paʻa ponoʻī, pahu pahu pahu pālua pālua, pahu keleawe hoʻokahi, etc.

ʻO ka pahu keleawe papa uila (maʻemaʻe ma luna o 99.7%, mānoanoa 5um-105um) kekahi o nā mea kumu o ka ʻoihana uila. ʻO ka hoʻomohala wikiwiki ʻana o ka ʻoihana ʻike uila, ke hoʻonui nei ka hoʻohana ʻana i ka pepa keleawe uila uila, a hoʻohana nui ʻia nā huahana i nā helu helu ʻoihana, nā lako kamaʻilio, nā lako QA, nā pā lithium-ion, nā kīwī kīwila, nā mea hoʻopaʻa wikiō, nā mea pāʻani CD, nā kope kope, kelepona, ea ea, nā ʻāpana uila kaʻa, nā ʻoliʻoli pāʻani, a me nā mea ʻē aʻe. Ke piʻi nui nei nā mākeke kūloko a me nā ʻāina ʻē no ka pepa keleawe uila, ʻoi aku ka hana kiʻekiʻe. Wahi a nā hui ʻoihana pili i ka makahiki 2015, hiki i ka 300,000 tons ke koi kūloko o Kina no ka pepa keleawe papa uila, a e lilo ʻo Kina i kumu hana nui loa o ka honua no nā papa kaapuni paʻi a me nā pahu keleawe. Manaʻo maikaʻi ka mākeke no ka pepa keleawe papa uila, ʻoi aku ka nui o ka pahu kiʻekiʻe. .

3. ka hoʻolako honua o ke keleawe foil

Hiki ke hoʻokaʻawale ʻia nā ʻāpana keleawe ʻenehana i ʻelua mau ʻāpana: ʻōwili keleawe ʻōwili (RA copper foil) a me point solution copper foil (ED copper foil). Ma waena o lākou, he ductility maikaʻi a me nā hiʻohiʻona ʻē aʻe, i hoʻohana ʻia i ke kaʻina papa palupalu mua. Copper foil, a me electrolytic copper foil i ka pono o ka emi manufacturing kumu ma mua o'ōwili keleawe foil. No ka mea he mea koʻikoʻi ka ʻōpala keleawe i ʻōwili ʻia no nā papa maʻalahi, ʻo ka hoʻomaikaʻi ʻana i nā hiʻohiʻona a me nā hoʻololi kumukūʻai o ka pahu keleawe i ʻōwili ʻia i kekahi hopena i ka ʻoihana papa maʻalahi.

Ma muli o ka liʻiliʻi o nā mea hana o ka pahu keleawe i ʻōwili ʻia, a aia hoʻi ka ʻenehana i ka lima o kekahi mau mea hana, he haʻahaʻa haʻahaʻa ka mana o nā mea kūʻai aku ma luna o ke kumukūʻai a me ka lako. No laila, me ka hoʻopili ʻole ʻana i ka hana huahana, hoʻohana ʻia ka foil keleawe electrolytic ma kahi o ka ʻōwili ʻia ʻana o Copper foil kahi hopena kūpono. Eia nō naʻe, inā e hoʻopili nā waiwai kino o ka pahu keleawe i nā mea etching i nā makahiki e hiki mai ana, e hoʻonui hou ʻia ka mea nui o ka pahu keleawe i ʻōwili ʻia i nā huahana lahilahi a lahilahi paha, a me nā huahana kiʻekiʻe ma muli o ka noʻonoʻo ʻana i ke kelepona.

ʻElua mau mea keakea nui i ka hana ʻana i nā ʻāpana keleawe i ʻōwili ʻia, nā pilikia kumu a me nā pilikia ʻenehana. ʻO ka pale kumu waiwai e pili ana i ka pono o ke keleawe maka mea e kākoʻo ai i ka hana ʻana o ka pahu keleawe i ʻōwili ʻia, a he mea nui loa ka noho ʻana i nā kumuwaiwai. Ma ka ʻaoʻao ʻē aʻe, hoʻonāwaliwali nā pilikia ʻenehana i nā mea komo hou. Ma waho aʻe o ka ʻenehana calendering, hoʻohana ʻia ka ʻenehana lapaʻau oxidation. ʻO ka hapa nui o nā hale hana honua he nui nā patent ʻenehana a me nā ʻenehana kī Know How, kahi e hoʻonui ai i nā pale i ke komo ʻana. Inā ʻo ka poʻe komo hou i ka hoʻoili ʻana a me ka hana ʻana, ua kāohi ʻia lākou e ke kumukūʻai o nā mea hana nui, a ʻaʻole maʻalahi ke komo ʻana i ka mākeke. No laila, ʻo ka global rolled copper foil no ka mākeke me ka ikaika kūʻokoʻa.

3. ka hoʻomohala ʻana o ke keleawe keleawe

ʻO Copper Foil ma ka ʻōlelo Pelekania he electrodepositedcopperfoil, he mea nui ia no ka hana ʻana i ka copper clad laminate (CCL) a me ka papa kaapuni paʻi (PCB). I ka hoʻomohala wikiwiki ʻana o ka ʻoihana ʻike uila, ua kapa ʻia ʻo electrolytic copper foil: ka "neural network" o ka hōʻailona huahana uila a me ka hoʻouna ʻana i ka mana a me ke kamaʻilio. Mai ka makahiki 2002, ua ʻoi aku ka waiwai o nā papa kaapuni i paʻi ʻia ma Kina i ke kolu o ka wahi ma ka honua, a ua lilo nā laminates keleawe, ka mea substrate o nā PCB, i ke kolu o ka mea hana nui loa ma ka honua. ʻO ka hopena, ua hoʻomohala ʻia ka ʻoihana copper foil electrolytic o Kina e nā lele a me nā palena i nā makahiki i hala. I mea e hoʻomaopopo a hoʻomaopopo i ka wā i hala a me kēia manawa o ka honua a me ka hoʻomohala ʻana o ka ʻoihana keleawe electrolytic o Kina, a nānā i mua i ka wā e hiki mai ana, ua loiloi nā poʻe loea mai ka China Epoxy Resin Industry Association i kona hoʻomohala ʻana.

Mai ka hiʻohiʻona o ka ʻoihana hana a me ka ulu ʻana o ka mākeke o ka ʻoihana electrolytic copper foil, hiki ke hoʻokaʻawale ʻia kāna kaʻina hana hoʻomohala i ʻekolu mau manawa hoʻomohala nui: ua hoʻokumu ʻo ʻAmelika Hui Pū ʻIa i ka ʻoihana keleawe keleawe mua loa a me ka manawa i hoʻomaka ai ka ʻoihana electrolytic copper foil; ʻO ka pahu keleawe Iapana ʻO ka manawa i hoʻokō pono ai nā ʻoihana i ka mākeke honua; ʻO ka manawa i hoʻohālikelike ʻia ka honua e hoʻokūkū no ka mākeke.
