Ngokukhanga okuphezulu emikhiqizweni ehlukahlukene yezimboni, ithusi libukwa njengento eguquguqukayo kakhulu.
Ama-foils ethusi akhiqizwa ngezinqubo ezikhethekile zokukhiqiza ngaphakathi kwe-foil mill ehlanganisa zombili ukugoqa okushisayo nokubandayo.
Kanye ne-aluminium, ithusi lisetshenziswa kabanzi emikhiqizweni yezimboni njengento eguquguqukayo phakathi kwezinto ezingezinhle kakhulu zensimbi. Ikakhulu eminyakeni yamuva, isidingo se-foil yethusi sesidluliselwe imikhiqizo kagesi kufaka phakathi izingcingo, amakhamera edijithali, namadivayisi we-IT.
I-Foil Fabrication
Ama-Foils ama-Frow Compus akhiqizwa nge-electrodeposition noma ukugoqa. Okwe-Electrodeposition High Grade Copper kufanele ichithwe ku-acid ukukhiqiza i-electrolyte ye-Copper. Lesi sixazululo se-electrolyte siphonswa emgqonyeni wezigungu okuphakathi nendawo, okujikelezayo okukhokhiswa ngogesi. Kule migqomo ifilimu elincanyana le-zethusi yi-electrodepos. Le nqubo iyaziwa nangokuthi Pliating.
Enqubweni yokukhiqiza ye-Electrodepososited, i-foil ye-Copper ifakwe kwisigubhu esijikelezayo se-titanium esikhaleni se-zethusi lapho ixhunywe khona emthonjeni we-voltage voltage. I-CATHODE inamathiselwe kwisigubhu kanti i-anode ifakwe kwikhambi le-elecpercytete yethusi. Lapho insimu kagesi isetshenziswa, ithusi lifakwa kwisigubhu njengoba lijikeleza ngejubane elihamba kancane. Indawo yethusi esihlangothini lwesigubhu ibushelelezi ngenkathi uhlangothi oluphambene lunzima. Ijubane lesigubhu esihamba kancane, ubukhulu bethusi bathola futhi okuphambene nalokho. I-Copper ikhangwa futhi yanqwabelana endaweni ye-cathode yesigubhu se-titanium. Uhlangothi lwe-matte ne-drum lwe-foil ye-post kudlula ngemijikelezo yokwelashwa ehlukene ukuze ithusi lilungele ukubonwa kwe-PCB. Izindlela zokwelapha zithuthukisa ukunamathela phakathi kwe-Copper ne-Dielectric interlayer ngesikhathi senqubo yokuqashwa kweCopper Crad. Enye inzuzo yokwelashwa ukwenza njenge-anti-tarnish ejenti ngokunciphisa i-oxidation yethusi.
Umdwebo 1:I-Electrodeposososited Procuting Prodvice Procepectifice 2 ibonisa izinqubo zokukhiqiza zemikhiqizo ye-Colled Copper. Imishini yokugoqa ihlukaniswe izinhlobo ezintathu; Okungukuthi, ukugaya okushisayo okushisayo, ama-coller rolling mills, kanye nama-foil mill.
Amakhoyili ama-foils ancanyana akhiwa futhi athola ukwelashwa okulandelayo kwamakhemikhali nokwelashwa kuze kube yilapho senziwa esimweni sabo sokugcina. Ukubuka konke kwenqubo yenqubo yokugoqa kwama-foils ethusi kunikezwe kuMdwebo 2. Ibhulokhi yethusi eliphonswe (ubukhulu be-5mx1mx130mm) bufudunyezwa kuze kube ngu-750 ° C. Ngemuva kwalokho, kuyashisa kuvuselelwa emuva ngezinyathelo eziningana phansi kuya ku-1/10 ngobukhulu bayo bokuqala. Ngaphambi kokuba kubanda kokuqala okubandayo kwesikali esivela ekuthini ukwelashwa kokushisa sisuswa ngokugaya. Enqubweni yokugoqa okubandayo Ubukhulu buyancishiswa baba cishe ngo-4 mm futhi amashidi akhiwa amakhoyili. Le nqubo ilawulwa ngendlela yokuthi izinto zithola isikhathi eside futhi zingashintshi ububanzi bayo. Njengoba amashidi engakwazi ukwakhiwa okuthe xaxa kulesi simo (okuqukethwe kusebenza kulukhuni kakhulu) athola ukwelashwa okushisa futhi afudunyezwa cishe ngo-550 ° C.
