Ifoyile yobheduiimveliso zisetyenziswa ikakhulu kushishino ibhetri lithium, ishishini lerediyethakunye noshishino lwePCB.
I-1.I-Electro ifakwe i-copper foil (i-ED copper foil) ibhekisela kwi-foil yobhedu eyenziwe yi-electrodeposition. Inkqubo yokwenziwa kwayo yinkqubo ye-electrolytic. I-cathode roller iya kutsala i-ion zetsimbi zetsimbi ukwenza i-electrolytic foil eluhlaza. Njengoko i-cathode roller ijikeleza ngokuqhubekayo, i-foil eluhlaza eyenziwe ngokuqhubekayo ixutywe kwaye ihlulwe kwi-roller. Emva koko iyahlanjwa, yomiswe, ize ifakwe kumqulu wefoyile ekrwada.
I-2.RA, i-rolled annealed copper foil, yenziwa ngokucubungula i-ore yethusi kwi-ingots zethusi, emva koko i-pickling kunye ne-degreasing, kunye nokutshisa ngokuphindaphindiweyo kunye ne-calendering kwiqondo lokushisa eliphezulu ngaphezu kwe-800 ° C.
3.HTE, ubushushu obuphezulu bobude be-electro efakwe kwifoyile yobhedu, yifoyile yobhedu egcina ubude obugqwesileyo kubushushu obuphezulu (180℃). Phakathi kwazo, ubude be-35μm kunye ne-70μm yefoyile yobhedu engqindilili kubushushu obuphezulu (180℃) kufuneka bugcinwe ngaphezu kwe-30% yobude kwiqondo lobushushu begumbi. Ikwabizwa ngokuba yi-HD copper foil (i-high ductility copper foil).
I-4.RTF, i-foil ye-copper ephathwayo yokubuyela umva, ebizwa ngokuba yi-reverse copper foil, iphucula ukunamathela kunye nokunciphisa uburhabaxa ngokongeza i-resin ethile yokwaleka kwindawo ecwebezelayo yefoyile yobhedu ye-electrolytic. Uburhabaxa ngokubanzi buphakathi kwe-2-4um. Icala lefoyile yobhedu edityaniswe kumgangatho wentlaka inoburhabaxa obuphantsi kakhulu, ngelixa icala elirhabaxa lefoyile yobhedu lijonge ngaphandle. Uburhabaxa befoyile yobhedu obuphantsi be-laminate buluncedo kakhulu ekwenzeni iipatheni zesekethe ezintle kumaleko angaphakathi, kwaye icala elibi liqinisekisa ukunamathela. Xa i-roughness surface ephantsi isetyenziselwa izibonakaliso ze-high-frequency, ukusebenza kombane kuphuculwe kakhulu.
I-5.DST, i-foil yobhedu yonyango yecala eliphindwe kabini, i-roughening zombini iindawo ezigudileyo kunye nezibi. Eyona njongo iphambili kukunciphisa iindleko kunye nokugcina unyango umphezulu ubhedu kunye namanyathelo browning phambi lamination. Ukungalungi kukuba umphezulu wobhedu awukwazi ukukrwela, kwaye kunzima ukususa ungcoliseko xa ungcolisekile. Isicelo sihla kancinci kancinci.
I-6.LP, i-foil yobhedu ephantsi. Ezinye iifoyile zethusi ezineeprofayili ezisezantsi ziquka i-VLP ye-copper foil (I-foil ye-copper ephantsi kakhulu), i-HVLP i-copper foil (i-High Volume Low Pressure), i-HVLP2, njl. ngaphandle kweekristale ze-columnar, kwaye ziikristale ze-lamellar ezinemiphetho ecaba, ehambelana nokuhanjiswa komqondiso.
I-7.RCC, i-resin coated foil copper, eyaziwa ngokuba yi-resin copper foil, i-adhesive-backed copper foil. Yifoyile yobhedu ebhityileyo ye-electrolytic (ukutyeba ngokuqhelekileyo yi-≦18μm) inomaleko omnye okanye emibini yeglue eyenziwe ngokukodwa yeresin (inxalenye ephambili yeresin idla ngokuba yiresin epoxy) eqatywe kumphezulu orhabaxa, kwaye isinyibilikisi sisuswa ngokomiswa ngaphakathi. i-oveni, kwaye i-resin iba yinqanaba B le-semi-cured.
I-8.UTF, ifoyile yobhedu ecekeceke kakhulu, ibhekisa kwifoyile yobhedu enobunzima obungaphantsi kwe-12μm. Eyona nto ixhaphakileyo yi-foil yobhedu engaphantsi kwe-9μm, esetyenziselwa ukuveliswa kweebhodi zesekethe eziprintiweyo kunye neesekethe ezintle kwaye ngokubanzi zixhaswa ngumthwali.
