1. Intshayelelo yeFoil yeCopper
I-foil yobhedu (i-copper foil): uhlobo lwe-cathode electrolytic material, i-conductor ye-PCB enqabileyo, eqhubekayo efakwe kwisiseko sebhodi yesekethe, esebenza njengomqhubi we-PCB. Ibambelela ngokulula kwi-insulating layer, iyamkela umaleko wokukhusela oprintiweyo, kwaye wenze iphethini yesiphaluka emva kokubola. Uvavanyo lwesipili sobhedu (uvavanyo lwesipili sobhedu): uvavanyo lwe-flux corrosion, usebenzisa ifilimu ye-vacuum deposition kwipleyiti yeglasi.
I-foil yobhedu yenziwe ngobhedu kunye nomlinganiselo othile wezinye iintsimbi. I-foil ye-Copper ngokubanzi ine-foil engama-90 kunye ne-88 ye-foil, oko kukuthi, umxholo wobhedu ngu-90% kunye ne-88%, kwaye ubungakanani buyi-16 * 16cm. I-foil yobhedu iyona nto isetyenziswa kakhulu kwizinto zokuhlobisa. Njenge: iihotele, iitempile, imifanekiso eqingqiweyo kaBuddha, iimpawu zegolide, iimosaic zeethayile, imisebenzi yezandla, njl.
2. Iimpawu zemveliso
I-copper foil ineempawu ezisezantsi ze-oksijini kwaye inokudityaniswa kwii-substrates ezahlukeneyo, ezinjengezinyithi, izinto zokukhusela, njl., kwaye inoluhlu olubanzi lokushisa. Isetyenziswa kakhulu kwi-electromagnetic shielding kunye ne-antistatic. I-copper ye-copper foil ifakwe phezu kwe-substrate kwaye idibaniswe ne-metal substrate, ene-conductivity egqwesileyo kwaye inika umphumo wokukhusela i-electromagnetic. Inokwahlulwa ibe yi: i-self-adhesive copper foil, i-foil-conducting copper foil, i-single-conducting copper foil, njl.
Ifoyile yobhedu yomgangatho we-elektroniki (ubunyulu obungaphezulu kwe-99.7%, ubukhulu be-5um-105um) yenye yezinto ezisisiseko kushishino lwe-elektroniki. Uphuhliso olukhawulezayo lweshishini lolwazi lwe-elektroniki, ukusetyenziswa kwefoyile yobhedu yomgangatho we-elektroniki kuyanda, kwaye iimveliso zisetyenziswa ngokubanzi kwiikhatyhuleyitha zoshishino, izixhobo zoNxibelelwano, izixhobo ze-QA, iibhetri ze-lithium-ion, oomabonwakude basekuhlaleni, abarekhodi bevidiyo, abadlali beCD, oomatshini bokufotokopa, iimfonomfono, umoya wokupholisa umoya, iikhomponenti zeemoto ze-elektroniki, izixhobo zomdlalo we-elektroniki, njl.njl. Iimarike zasekhaya nezangaphandle zinemfuno eyandayo yefoyile yobhedu yodidi lwe-elektroniki, ingakumbi ifoyile yobhedu esebenza kwibakala eliphezulu. Imibutho yeengcali ezifanelekileyo ziqikelela ukuba ngo-2015, imfuno yasekhaya yaseTshayina yefoyile yobhedu yodidi lwe-elektroniki iya kufikelela kwiitoni ezingama-300,000, kwaye iTshayina iya kuba sesona siseko sikhulu sokwenza iibhodi zesekethe eziprintiweyo kunye neefoyile zobhedu. Imarike yefoyile yobhedu yomgangatho we-elektroniki, ngakumbi i-foil ephezulu yokusebenza, inethemba. .
3. ukunikezelwa kwehlabathi jikelele kwefoyile yobhedu
I-foil yobhedu ye-Industrial inokwahlulwa ngokuqhelekileyo ibe ngamacandelo amabini: i-foil yobhedu eqengqelekayo (i-RA copper foil) kunye ne-point solution ye-copper foil (i-ED copper foil). Phakathi kwabo, i-foil yobhedu ephothiweyo ine-ductility enhle kunye nezinye iimpawu, ezisetyenziselwa inkqubo yebhodi ethambileyo yokuqala. I-copper foil, kunye ne-electrolytic copper foil ine-advanteji yexabiso eliphantsi lokwenziwa kweendleko kune-rolled copper foil. Ekubeni i-foil yobhedu ephothiweyo yinto ebalulekileyo ekrwada kwiibhodi eziguquguqukayo, ukuphuculwa kweempawu kunye nokutshintshwa kwexabiso le-foil yobhedu ephothiweyo kunempembelelo ethile kwishishini lebhodi eliguquguqukayo.
Ekubeni kukho abavelisi abambalwa be-foil yobhedu eqengqelekayo, kwaye iteknoloji isesandleni sabanye abavelisi, abathengi banezinga eliphantsi lokulawula ixabiso kunye nokubonelela. Ngoko ke, ngaphandle kokuchaphazela ukusebenza kwemveliso, i-electrolytic copper foil isetyenziswa endaweni yokuqengqeleka iCopper foil sisisombululo esinokwenzeka. Nangona kunjalo, ukuba iipropathi ezibonakalayo ze-foil yobhedu ngokwayo ziya kuchaphazela izinto ezithintekayo kwiminyaka embalwa ezayo, ukubaluleka kwe-foil yobhedu eqengqelekayo kuya kunyuka kwakhona kwiimveliso ezinqabileyo okanye ezincinci, kunye neemveliso eziphezulu ze-frequency ngenxa yoqwalaselo lonxibelelwano.
Kukho imiqobo emibini engundoqo ekuvelisweni kwefoyile yobhedu esongiweyo, imiqobo yemithombo kunye nemiqobo yobugcisa. Isithintelo sobutyebi sibhekisa kwimfuno yezinto zobhedu zokuxhasa ukuveliswa kwefoyile yobhedu eqengqelekayo, kwaye kubaluleke kakhulu ukuhlala kwizibonelelo. Kwelinye icala, imiqobo yobugcisa iyabatyhafisa abangeneleli abatsha. Ukongeza kwitekhnoloji ye-calendering, unyango lwangaphezulu okanye iteknoloji yonyango lwe-oxidation iyasetyenziswa. Uninzi lweefektri ezinkulu zehlabathi zinamalungelo awodwa omenzi wetekhnoloji kunye nobuchwephesha obungundoqo Yazi Njani, obunyusa imiqobo ekungeneni. Ukuba abangenisi abatsha emva kokuvuna ukusetyenzwa kunye nokuveliswa, banqandwa ngeendleko zabakhiqizi abakhulu, kwaye akulula ukujoyina ngempumelelo kwimarike. Ke ngoko, ifoyile yobhedu eqengqelekisiweyo yehlabathi iseyeyentengiso kwaye ikhethekile.
3. ukuphuhliswa kwefoyile yobhedu
I-copper foil ngesiNgesi yi-electrodepositedcopperfoil, into ebalulekileyo yokwenziwa kwe-copper clad laminate (CCL) kunye nebhodi yesekethe eprintiweyo (PCB). Kuphuhliso lwanamhlanje olukhawulezayo lweshishini lolwazi lombane, ifoyile yobhedu ye-electrolytic ibizwa ngokuba: “inethiwekhi ye-neural” yophawu lwemveliso ye-elektroniki kunye nokuhanjiswa kwamandla kunye nonxibelelwano. Ukususela ngo-2002, ixabiso lemveliso yeebhodi zesekethe eziprintiweyo e-China liye ladlula indawo yesithathu emhlabeni, kunye ne-laminates yobhedu, i-substrate material ye-PCBs, iye yaba ngumvelisi wesithathu ngobukhulu emhlabeni. Ngenxa yoko, imveliso yefoyile yobhedu yaseTshayina iphuhliswe ngokutsiba kunye nemida kwiminyaka yakutshanje. Ukuze uqonde kwaye uqonde ixesha elidlulileyo nelikhoyo kwihlabathi kunye nophuhliso lweshishini le-foil ye-electrolytic yaseTshayina, kwaye sijonge phambili kwikamva, iingcali ezivela kwi-China Epoxy Resin Industry Association zihlolisise uphuhliso lwayo.
Ngokombono wesebe lemveliso kunye nophuhliso lwemarike yoshishino lwefoyile yobhedu ye-electrolytic, inkqubo yophuhliso lwayo inokwahlulwa ibe ngamaxesha amathathu ophuhliso: iUnited States yaseka ishishini lokuqala lehlabathi lobhedu kunye nexesha apho ushishino lwefoyile yobhedu lwe-electrolytic lwaqala; Ifoyile yobhedu yaseJapan Ixesha apho amashishini elawula ngokupheleleyo imarike yehlabathi; ixesha apho ihlabathi lihlukaniswe ngeendlela ezininzi ukukhuphisana kwimarike.
