Ucwecwe lwethusi lwe-CNZHJ lunokuhamba kahle kukagesi, ukuhlanzeka okuphezulu, ukunemba okuhle, i-oxidation encane, ukumelana namakhemikhali okuhle, kanye nokufakwa kalula. Ngesikhathi esifanayo, ukuze kuhlangatshezwane nezidingo zokucubungula zamakhasimende ahlukene, i-CNZHJ ingakwazi ukusika i-foil yethusi ibe amashidi, angasindisa amakhasimende izindleko eziningi zokucubungula.
Iisithombe sokubukekaye-foil yethusi kanye nesithombe sokuskena se-electron microscope simi kanje:
Ubukhulu nesisindo se-foil yethusi(Kucashunwe ku-IPC-4562A)
Ugqinsi lwethusi lwebhodi le-PCB eligqoke ithusi livamise ukuvezwa ngama-ounces (oz), 1oz=28.3g, njengo-1/2oz, 3/4oz, 1oz, 2oz. Isibonelo, isisindo sendawo esingu-1oz/ft² silingana no-305 g/㎡ kumayunithi e-metric. , iguqulelwe ukuminyana kwethusi (8.93 g/cm²), okulingana nokujiya okungu-34.3um.
Incazelo ye-foil yethusi "1/1": i-foil yethusi enendawo yesikwele esingu-1 kanye nesisindo se-ounce engu-1; usakaze i-ounce yethusi ngokulinganayo epuleti elinendawo engu-1 square foot.
Ubukhulu nesisindo se-foil yethusi
☞ED, i-Electrodeposited copper foil (ED copper foil), ibhekisela kucwecwe lwethusi olwenziwe nge-electrodeposition. Inqubo yokukhiqiza iyinqubo ye-electrolysis. Imishini ye-Electrolysis ngokuvamile isebenzisa i-roller engaphezulu eyenziwe nge-titanium material njenge-cathode roller, ingxubevange encibilikayo esekelwe ku-lead engancibiliki njenge-anode, futhi i-sulfuric acid yengezwa phakathi kwe-cathode ne-anode. I-electrolyte yethusi, ngaphansi kwesenzo samanje esiqondile, ine-ion yensimbi yethusi ekhangiswe kurola ye-cathode ukuze yakhe ucwecwe lwangempela lwe-electrolytic. Njengoba i-cathode roller iqhubeka nokujikeleza, ucwecwe lwangempela olukhiqiziwe lukhangiswa ngokuqhubekayo futhi luhlutshiwe ku-roller. Ngemva kwalokho iyagezwa, yomiswe, futhi ifakwe emqulwini we-foil eluhlaza. Ukuhlanzeka kwe-foil yethusi kungu-99.8%.
☞RA, ucwecwe lwethusi olugoqiwe, lukhishwa kunsimbi yethusi ukuze kukhiqizwe ithusi lebhamuza, elincibilikiswa, licutshungulwe, lihlanzwe ngogesi, bese lenziwa izingothi zethusi ezingaba wugqinsi oluyi-2mm. Ingot yethusi isetshenziswa njengento eyisisekelo, efakwe emanzini anosawoti, encibilikisiwe, futhi ishiswe futhi igoqwe (endaweni ende) emazingeni okushisa angaphezu kuka-800 ° C izikhathi eziningi. Ubumsulwa 99.9%.
☞HTE, ucwecwe lwekhopha olunezinga eliphezulu lokushisa elenziwe nge-electrodeposited, icwecwe lethusi eligcina ubude obuhle kakhulu emazingeni okushisa aphezulu (180°C). Phakathi kwazo, ukunwetshwa kwe-foil yethusi enogqinsi okungama-35μm no-70μm ekushiseni okuphezulu (180℃) kufanele kugcinwe kungaphezu kuka-30% wobude ekamelweni lokushisa. Ibizwa nangokuthi i-HD copper foil (i-high ductility copper foil).
I-☞DST, icwecwe lekhopha elihlanjululwe emaceleni amabili, yenza rough kokubili indawo ebushelelezi nengamaholoholo. Inhloso eyinhloko yamanje ukunciphisa izindleko. Ukuqinisa indawo ebushelelezi kungasindisa ukwelapha kwendawo yethusi kanye nezinyathelo zokuba nsundu ngaphambi kokucwasa. Ingasetshenziswa njengesendlalelo sangaphakathi se-foil yethusi yamabhodi anezingqimba eziningi, futhi ayidingi ukuba ibe nsundu (imnyama) ngaphambi kokukhanyisa amabhodi anezingqimba eziningi. Okubi ukuthi indawo yethusi akufanele iklwebhe, futhi kunzima ukuyikhipha uma kukhona ukungcola. Njengamanje, ukusetshenziswa kocwecwe lwethusi olunamacala amabili kuncipha kancane kancane.
☞I-UTF, ucwecwe lwethusi oluncane kakhulu, isho ucwecwe lwethusi olunogqinsi olungaphansi kuka-12μm. Okuvame kakhulu ama-foil ethusi angaphansi kuka-9μm, asetshenziswa kumabhodi wesekethe aphrintiwe ukwenza amasekhethi amahle. Ngenxa yokuthi ucwecwe lwethusi oluncane kakhulu kunzima ukuluphatha, ngokuvamile lusekelwa umthwali. Izinhlobo zokuthwala zihlanganisa i-copper foil, i-aluminium foil, ifilimu ye-organic, njll.
