I-Copper ingenye yezinsimbi ezisebenza ngezindlela ezihlukahlukene kakhulu emhlabeni. Izakhiwo zayo eziyingqayizivele ziyenza ifaneleke ezinhlobonhlobo zezinhlelo zokusebenza, kufaka phakathi ukuqhutshwa kukagesi. I-Copper isetshenziswa kakhulu ezimbonini zikagesi neze-elekthronikhi, futhi ama-foil ethusi ayizingxenye ezibalulekile zokukhiqiza amabhodi esekethe aphrintiwe (PCBs). Phakathi kwezinhlobo ezahlukene zamafoyili ethusi asetshenziswa ekukhiqizeni ama-PCB, i-ED copper foil iyona esetshenziswa kakhulu.
I-ED ye-copper foil ikhiqizwa i-electro-deposition (ED), okuyinqubo ehilela ukubekwa kwama-athomu ethusi endaweni eyinsimbi kusetshenziswa amandla kagesi. I-foil yethusi ewumphumela ihlanzeke kakhulu, iyafana, futhi inezakhiwo ezinhle kakhulu zomshini nogesi.
Enye yezinzuzo eziyinhloko ze-ED copper foil ukufana kwayo. Inqubo ye-electro-deposition iqinisekisa ukuthi ukujiya kwefoyili yethusi kuyahambisana kuyo yonke indawo yayo, okubalulekile ekukhiqizeni i-PCB. Ubukhulu befoyili yethusi ngokuvamile bucaciswa kuma-microns, futhi bungasukela kuma-microns ambalwa kuye kwamashumi amaningana ama-microns, kuye ngohlelo lokusebenza. Ubukhulu be-foil yethusi bunquma ukuqhutshwa kwayo kagesi, futhi i-foil ewugqinsi ngokuvamile inokusebenza okuphezulu.
Ngaphezu kokufana kwayo, i-ED ye-copper foil inezakhiwo ezinhle kakhulu zemishini. Iguquguquka kakhulu futhi ingagoba kalula, ibunjwe, futhi yakheke ukuze ilingane ne-PCB. Lokhu kuvumelana nezimo kuyenza ibe into efanelekile yokukhiqiza ama-PCB anejometri eyinkimbinkimbi kanye nemiklamo eyinkimbinkimbi. Ngaphezu kwalokho, i-ductility ephezulu ye-foil yethusi ivumela ukuthi imelane nokugoba okuphindaphindiwe nokuguquguquka ngaphandle kokuqhekeka noma ukuphuka.
Enye impahla ebalulekile ye-ED yethusi ye-copper yi-conductivity yayo kagesi. I-Copper ingenye yezinsimbi ezihamba phambili, futhi i-ED ye-copper foil ine-conductivity engaphezu kuka-5×10^7 S/m. Leli zinga eliphezulu le-conductivity libalulekile ekukhiqizeni ama-PCB, lapho lenza khona ukudluliswa kwezimpawu zikagesi phakathi kwezingxenye. Ngaphezu kwalokho, ukumelana nogesi okuphansi kwe-foil yethusi kunciphisa ukulahlekelwa amandla esignali, okubalulekile ekusetshenzisweni kwejubane eliphezulu kanye ne-high-frequency.
I-ED ye-copper foil nayo imelana kakhulu ne-oxidation nokugqwala. I-Copper ihlangana nomoya-mpilo emoyeni ukuze yakhe ungqimba oluncane lwe-copper oxide ebusweni bayo, olungafaka engozini ukusebenza kwayo kukagesi. Kodwa-ke, ucwecwe lwethusi lwe-ED luvamise ukumbozwa ngongqimba lwezinto ezivikelayo, njengethayela noma i-nickel, ukuze kuvinjelwe i-oxidation futhi kuthuthukiswe ukudayiswa kwayo.
Sengiphetha, i-ED copper foil iyinto eguquguqukayo futhi ebalulekile ekukhiqizeni ama-PCB. Ukufana kwayo, ukuguquguquka, ukuguquguquka kukagesi okuphezulu, nokumelana ne-oxidation nokugqwala kuyenza ibe into efanelekile yokukhiqiza ama-PCB anamajometri ayinkimbinkimbi kanye nezidingo zokusebenza okuphezulu. Ngokukhula kwesidingo sama-elekthronikhi anesivinini esikhulu kanye nemvamisa ephezulu, ukubaluleka kwefoyili yethusi ye-ED kusethwe ukuthi kukhule eminyakeni ezayo.
