Inkqubo yokwenziwa kweFoil yeCopper kwiFactory

Ngesibheno esiphezulu kwiimveliso ezininzi zeemveliso, ubhedu lubonwa njengento eninzi kakhulu.

Iifoyile zobhedu ziveliswa ziinkqubo zokwenziwa ezithe ngqo ngaphakathi kwelitye lokusila elibandakanya ukuqengqeleka okushushu nokubanda.

Kunye ne-aluminiyam, ubhedu lusetyenziswa ngokubanzi kwiimveliso zemizi-mveliso njengezinto eziguquguqukayo kakhulu phakathi kwezinto ezingezizo intsimbi.Ngokukodwa kule minyaka yakutsha nje, imfuno yefoyile yobhedu iye yanda kakhulu kwiimveliso zombane ezibandakanya iiselfowuni, iikhamera zedijithali, kunye nezixhobo ze-IT.

Ukwenziwa kwefoyile

Iifoyile zobhedu ezibhityileyo ziveliswa nge-electrodeposition okanye ngokuqengqeleka.Kuba i-electrodeposition yomgangatho ophezulu wobhedu kufuneka ichithwe kwi-asidi ukuvelisa i-electrolyte yobhedu.Esi sisombululo se-electrolyte simpontshelwa kwimigqomo entywiliselweyo ngokuyinxenye, ejikelezayo etshajwa ngombane.Kule migqomo ifilimu ebhityileyo yobhedu ifakwe kwi-electrodeposited.Le nkqubo ikwabizwa ngokuba yiplating.

Kwinkqubo yokwenziwa kobhedu lwe-electrodeposited, ifoyile yobhedu ifakwa kwi-titanium ejikeleza igubu ukusuka kwisisombululo sobhedu apho iqhagamshelwe kumthombo wombane we-DC.I-cathode ifakwe kwi-drum kwaye i-anode ifakwe kwisisombululo sobhedu se-electrolyte.Xa kufakwe indawo yombane, ubhedu lufakwa kwigubu njengoko lijikeleza ngesantya esicothayo.Umphezulu wobhedu kwicala legubu ugudile ngelixa elinye icala lirhabaxa.Okukhona licotha isantya segubu, kokukhona ubhedu luba ngqindilili kwaye ngokuphambeneyo.Ubhedu luyatsalwa kwaye luqokelelwe kumphezulu we-cathode we-titanium drum.Icala le-matte kunye ne-drum ye-foil yobhedu idlula kwimijikelo yonyango eyahlukeneyo ukuze ubhedu lulungele ukwenziwa kwe-PCB.Unyango luphucula ukunamathela phakathi kobhedu kunye ne-dielectric interlayer ngexesha lenkqubo yokulambisa yobhedu.Enye inzuzo yonyango kukusebenza njenge-anti-tarnish ngokucothisa i-oxidation yobhedu.

Umfanekiso 1:Inkqubo yokuVelisa i-Electrodeposited CopperFigure 2 ubonisa iinkqubo zokwenziwa kweemveliso zobhedu ezisongiweyo.Isixhobo sokuqengqeleka sahlulwe ngokweendidi ezintathu;ezizezi, ii- hot rolling Mills, ii-cold rolling Mill, kunye ne-foil.

Iikhoyili zeefoyile ezibhityileyo ziye zenziwe kwaye zingene kunyango olulandelayo lweekhemikhali kunye noomatshini de zibe yimo yazo yokugqibela.Isishwankathelo sesikim senkqubo yokuqengqeleka kweefoyile zobhedu inikwe kuMfanekiso 2. Ibloko yobhedu olutyhidiweyo (imilinganiselo eqikelelwayo: 5mx1mx130mm) ifudunyezwa ukuya kutsho kuma-750°C.Emva koko, ishushu iqengqeleke ngokubuyisela umva kwizinyuko ezininzi ukuya kuthi ga kwi-1/10 yobukhulu bayo bokuqala.Ngaphambi kokuqengqeleka kokuqala okubandayo izikali ezisuka kunyango lobushushu ziyasuswa ngokusila.Kwinkqubo ebandayo yokuqengqeleka ubunzima buncitshiswe malunga ne-4 mm kwaye amaphepha abunjwa kwiikhoyili.Inkqubo ilawulwa ngendlela yokuba izinto eziphathekayo zithatha ixesha elide kwaye azitshintshi ububanzi bayo.Njengoko ama-sheets engakwazi ukwakhiwa kwakhona kulo mmandla (izinto eziphathekayo zisebenze nzima kakhulu) bafumana unyango olushushu kwaye bashushu malunga ne-550 ° C.
