1.Development History of Copper Foil
Nhoroondo yefoil yemhangurainogona kuteverwa kumashure kuma1930s, apo mugadziri weAmerica Thomas Edison akagadzira patent yekuenderera mberi kugadzirwa kwesimbi yakatetepa foil, iyo yakave piyona wemazuva ano electrolytic copper foil tekinoroji. Mushure mezvo, Japan yakaunza uye yakagadzira tekinoroji iyi muma1960s, uye China yakawana yakakura-inoenderera mberi kugadzirwa kwemhangura foil mukutanga kwema1970.
2.Kuronga kwemhangura foil
Copper foilinonyanya kukamurwa muzvikamu zviviri: yakakungurutswa yemhangura foil (RA) uye electrolytic copper foil (ED).
Yakakungurutswa copper foil:yakagadzirwa nemaitiro emuviri, ine nzvimbo yakatsetseka, yakanaka conductivity uye mutengo wakakwira.
Electrolytic mhangura foil:yakagadzirwa ne electrolytic deposition, ine mutengo wakaderera, uye ndicho chigadzirwa chikuru pamusika.
Pakati pavo, electrolytic mhangura foil inogona kugovaniswazve mumhando dzakawanda kusangana nezvinodiwa zvakasiyana zvekushandisa:
● HTE copper foil:yakakwirira tembiricha kuramba, yakakwirira ductility, yakakodzera multi-layer PCB mabhodhi, akadai yepamusoro-performance maseva uye avionics midziyo.
Nyaya: Inspur Information's high-performance servers anoshandisa HTE copper foil kugadzirisa kupisa kwekutonga uye kusaina kutendeseka nyaya mupamusoro-inoshanda komputa.
● RTF foil yemhangura:Inovandudza kunamatira pakati pemhangura foil uye insulating substrate, inowanzoshandiswa mumotokari dzemagetsi ekudzora zvikamu.
Nyaya: CATL's bhatiri manejimendi system inoshandisa RTF mhangura foil kuti ive nechokwadi chekuvimbika uye kugadzikana pasi pemamiriro akanyanya.
●ULP foil yemhangura:Ultra-yakaderera mbiri, inoderedza ukobvu hwePCB mabhodhi, akakodzera kune dzakatetepa zvigadzirwa zvemagetsi senge mafoni.
Nyaya: Xiaomi's smartphone motherboard inoshandisa ULP copper foil kuwana yakareruka uye yakatetepa dhizaini.
● HVLP foil yemhangura:high-frequency ultra-low profile copper foil, inonyanya kukosheswa nemusika nekuda kwekuita kwayo kwechiratidzo chekufambisa. Iyo ine zvakanakira kuomarara kwepamusoro, yakatsetseka yakaomeswa pamusoro, yakanaka kugadzikana kwekupisa, yunifomu ukobvu, nezvimwewo, izvo zvinogona kuderedza kurasikirwa kwechiratidzo muzvigadzirwa zvemagetsi. Inoshandiswa kune yakakwira-kumhanya kutumira PCB mabhodhi akadai seakakwira-magumo maseva uye data data.
Nyaya: Munguva pfupi yapfuura, Solus Advanced Materials, mumwe weNvidia's core CCL suppliers muSouth Korea, akawana Nvidia yekupedzisira misa yekugadzira rezinesi uye achapa HVLP foil yemhangura kuDoosan Electronics kuti ishandiswe muchizvarwa chitsva cheNvidia cheAI accelerators iyo Nvidia inoronga kutanga gore rino.
3.Application maindasitiri uye nyaya
●Printed Circuit Board (PCB)
Copper foil, seye conductive layer yePCB, chinhu chakakosha chemidziyo yemagetsi.
Mhosva: Iyo PCB board inoshandiswa muHuawei's server ine yakakwira-chaiyo mhangura foil kuti iwane yakaoma dhizaini dhizaini uye yakakwirira-yekukurumidza data data.
●Lithium-ion bhatiri
Seyakaipa electrode ikozvino muunganidzi, foil yemhangura inoita basa rakakosha rekuita mubhatiri.
Mhosva: CATL's lithium-ion bhatiri inoshandisa yakanyanya conductive electrolytic copper foil, iyo inovandudza simba rebhatiri kusimba uye kuchaja uye kubuda zvakanaka.
● Electromagnetic Shielding
Mumichina yekurapa michina yeMRI uye zviteshi zvekutaurirana, foil yemhangura inoshandiswa kudzivirira kukanganiswa kwemagetsi.
Nyaya: United Imaging Medical's MRI midziyo inoshandisa copper foil zvinhu zve electromagnetic shielding, kuve nechokwadi chekujeka uye chokwadi chekufungidzira.
●Flexible Printed Circuit Board
Yakakungurutswa yemhangura foil yakakodzera kubhenda midziyo yemagetsi nekuda kwekushanduka kwayo.
Mhosva: Xiaomi wristband inoshandisa inochinjika PCB, uko foil yemhangura inopa inodiwa nzira yekufambisa uchichengetedza kuchinjika kwechishandiso.
● Consumer electronics, makombiyuta uye midziyo yakabatana
Copper foil inoita basa rekutanga mumabhodhi emidziyo yakadai sema smartphones nemalaptops.
Nyaya: Huawei's MateBook akatevedzana emalaptops anoshandisa yakanyanya conductive copper foil kuve nechokwadi chekuita uye kuvimbika kwechishandiso.
●Automotive electronics Mumota dzemazuvano
foil yemhangura inoshandiswa muzvikamu zvakakosha zvemagetsi senge injini yekudzora zvikamu uye mabhatiri manejimendi masisitimu.
Mhosva: Mota dzemagetsi dzeWeilai dzinoshandisa foil yemhangura kuvandudza bhatiri yekuchaja kushanda zvakanaka uye kuchengeteka.
● Mumidziyo yekukurukurirana yakadai se5G base stations uye routers
foil yemhangura inoshandiswa kuwana yakakwirira-kumhanya kufambisa data.
Mhosva: Huawei's 5G base station midziyo inoshandisa yakakwirira-inoshanda mhangura foil kutsigira yakakwirira-kumhanya kufambisa data uye kugadzirisa.
