3. da duniya samar da tagulla foil

Za a iya raba foil na jan ƙarfe na masana'antu fiye da nau'i biyu: birgima na jan karfe (RA copper foil) da bayani na jan karfe (ED copper foil). Daga cikin su, murfin jan ƙarfe na birgima yana da kyakkyawan ductility da sauran halaye, wanda aka yi amfani da shi a farkon tsarin jirgi mai laushi. Rufin jan ƙarfe, da foil ɗin tagulla na electrolytic yana da fa'idar ƙananan farashin masana'anta fiye da birgima na jan karfe. Tun da birgima na jan karfe yana da mahimmancin albarkatun ƙasa don allon sassa masu sassauƙa, haɓaka halaye da canje-canjen farashi na bangon jan ƙarfe na birgima yana da wani tasiri akan masana'antar jirgi mai sassauƙa.

Tun da akwai ƙarancin masana'antun da aka yi birgima na tagulla, kuma fasahar kuma tana hannun wasu masana'antun, abokan ciniki suna da ƙarancin iko akan farashi da samarwa. Don haka, ba tare da shafar aikin samfur ba, ana amfani da foil ɗin jan ƙarfe na lantarki maimakon mirgina foil ɗin Copper shine mafita mai yuwuwa. Duk da haka, idan abubuwan da ke cikin jikin tagulla da kanta za su yi tasiri ga abubuwan da ke haifar da etching a cikin 'yan shekaru masu zuwa, mahimmancin rubutun tagulla na birgima zai sake karuwa a cikin ƙananan samfurori ko ƙananan samfurori, da samfurori masu girma saboda la'akari da sadarwa.

Akwai manyan cikas guda biyu ga samar da foil ɗin tagulla na birgima, cikas na albarkatu da cikas na fasaha. Katangar albarkatun tana nufin buƙatar albarkatun tagulla don tallafawa samar da foil ɗin tagulla, kuma yana da matukar muhimmanci a mamaye albarkatu. A gefe guda, cikas na fasaha na hana ƙarin sabbin masu shiga. Baya ga fasahar calending, ana kuma amfani da fasahar jiyya ta sama ko oxidation. Yawancin manyan masana'antu na duniya suna da haƙƙin fasaha da yawa da fasaha mai mahimmanci Sani Ta yaya, wanda ke ƙara shingen shiga. Idan sabbin masu shigowa bayan girbi da samarwa, farashin manyan masana'antun ke hana su, kuma ba shi da sauƙi a samu nasarar shiga kasuwa. Sabili da haka, naɗaɗɗen bangon jan ƙarfe na duniya har yanzu yana cikin kasuwa tare da keɓantacce mai ƙarfi.

3. ci gaban tagulla foil

Rufin Copper a Turanci shi ne electrodepositedcopperfoil, wanda shine muhimmin abu don kera laminate na jan karfe (CCL) da kuma bugu na allo (PCB). A cikin saurin ci gaban masana'antar bayanai ta lantarki a yau, ana kiran foil ɗin tagulla na electrolytic: “cibiyar sadarwa ta jijiyoyi” na siginar samfuran lantarki da watsa wutar lantarki da sadarwa. Tun daga shekara ta 2002, yawan adadin allunan da'irar da aka buga a kasar Sin ya zarce matsayi na uku a duniya, kuma laminates na jan karfe, kayan da ake amfani da su na PCBs, sun zama na uku mafi girma a duniya. A sakamakon haka, masana'antar sarrafa tagulla ta kasar Sin ta samu ci gaba ta hanyar tsalle-tsalle a cikin 'yan shekarun nan. Domin fahimtar da fahimtar al'amuran da suka shude da kuma halin da ake ciki a duniya, da ci gaban masana'antar sarrafa tagulla ta kasar Sin, da sa ido a nan gaba, kwararru daga kungiyar masana'antar Epoxy Resin Resin na kasar Sin sun yi nazari kan ci gabanta.

Daga hangen nesa na samar da sashen da kasuwar ci gaban electrolytic tagulla masana'antu, da ci gaban tsarin za a iya raba uku manyan ci gaban lokaci: {asar Amirka ta kafa na farko duniya tagulla tsare sha'anin da kuma lokacin da electrolytic tagulla masana'antu fara; Bakin jan ƙarfe na Jafananci Lokacin da kamfanoni ke mamaye kasuwar duniya gabaɗaya; lokacin da duniya ke da yawa-polarized don yin gasa don kasuwa.
