I-copper foilimikhiqizo isetshenziswa kakhulu embonini yebhethri ye-lithium, imboni yerediyethakanye nemboni ye-PCB.
I-1.I-Electro deposited foil yethusi (i-ED copper foil) ibhekisela kucwecwe lwethusi olwenziwe nge-electrodeposition. Inqubo yayo yokukhiqiza iyinqubo ye-electrolytic. I-cathode roller izomunca ama-ion ethusi ensimbi ukuze yakhe i-electrolytic foil eluhlaza. Njengoba i-cathode roller ijikeleza ngokuqhubekayo, i-foil eluhlaza ekhiqizwa ngokuqhubekayo idonswa futhi ihlutshiwe ku-roller. Ngemva kwalokho iyagezwa, yomiswe, futhi ifakwe emqulwini we-foil eluhlaza.
I-2.RA, ucwecwe lwethusi olugoqiwe, lwenziwa ngokucubungula insimbi yethusi ibe yizingothi zethusi, bese icolwa futhi isuswe amafutha, bese ishisa ngokuphindaphindiwe igoqe futhi ifakwe ngekhalenda ezingeni lokushisa eliphezulu elingaphezu kuka-800°C.
I-3.HTE, ucwecwe lwe-electro lokwelulwa kwezinga lokushisa eliphezulu olufakwe ngethusi, lucwecwe lwethusi olugcina ukuphakama okuhle kakhulu ekushiseni okuphezulu (180℃). Phakathi kwazo, ubude be-foil yethusi engu-35μm no-70μm obukhulu obusezingeni lokushisa eliphezulu (180℃) kufanele bugcinwe ngaphezu kuka-30% wobude ekamelweni lokushisa. Ibizwa nangokuthi i-HD copper foil (i-high ductility copper foil).
I-4.RTF, ucwecwe lwethusi oluhlanekezelwe emuva, olubizwa nangokuthi i-reverse copper foil, ithuthukisa ukunamathela futhi yehlise ukuhwashala ngokungeza inhlaka ethile endaweni ecwebezelayo yefoyili yethusi ye-electrolytic. Ubulukhuni ngokuvamile buphakathi kuka-2-4um. Uhlangothi lwe-foil yethusi oluhlanganiswe nongqimba lwe-resin lunobunzima obuphansi kakhulu, kanti uhlangothi olumaholoholo lwecwecwe lethusi lubheke ngaphandle. I-foil ye-copper ephansi ye-roughness ye-laminate iyasiza kakhulu ekwenzeni amaphethini wesifunda esihle kungqimba lwangaphakathi, futhi uhlangothi olubi luqinisekisa ukunamathela. Lapho indawo esezingeni eliphansi isetshenziselwa amasignali amafrikhwensi aphezulu, ukusebenza kukagesi kuba ngcono kakhulu.
I-5.DST, icwecwe le-copper eliseceleni eliphindwe kabili, i-roughening zombili izindawo ezibushelelezi nezimangelengele. Inhloso eyinhloko ukunciphisa izindleko futhi ulondoloze ukwelashwa kwendawo yethusi kanye nezinyathelo ze-browning ngaphambi kokuqothula. Okubi ukuthi indawo yethusi ayikwazi ukuklwejwa, futhi kunzima ukususa ukungcola uma isingcolisiwe. Uhlelo lokusebenza luyancipha kancane kancane.
I-6.LP, i-foil yethusi yephrofayili ephansi. Amanye amacwecwe ethusi anamaphrofayili aphansi ahlanganisa ucwecwe lwethusi lwe-VLP (ucwecwe lwethusi oluphansi kakhulu), ucwecwe lwethusi lwe-HVLP (i-High Volume Low Pressure), i-HVLP2, njll. ngaphandle kwamakristalu ekholomu, futhi angamakristalu e-lamellar anemiphetho eyisicaba, evumela ukudluliswa kwesignali.
I-7.RCC, ucwecwe lwethusi oluhlanganiswe ne-resin, eyaziwa nangokuthi ucwecwe lwethusi lwe-resin, ucwecwe lwethusi olunamathelisiwe. Kuwucwecwe lwethusi oluncane lwe-electrolytic (ukujiya ngokuvamile ≦18μm) olunongqimba olulodwa noma ezimbili zeglue ye-resin eyakhiwe ngokukhethekile (ingxenye eyinhloko ye-resin ngokuvamile i-epoxy resin) embozwe endaweni eqinile, futhi isincibiliki sisuswa ngokomiswa ngaphakathi. kuhhavini, futhi inhlaka iba yisigaba B esilapheke kancane.
I-8.UTF, ucwecwe lwethusi oluncane kakhulu, lubhekisela kucwecwe lwethusi olunogqinsi olungaphansi kuka-12μm. Okuvame kakhulu i-foil yethusi engaphansi kwe-9μm, esetshenziselwa ukwakhiwa kwamabhodi wesifunda aphrintiwe anamasekhethi amahle futhi ngokuvamile asekelwa umthwali.
Icwecwe lethusi lekhwalithi ephezulu sicela uthinteinfo@cnzhj.com
