I-foil yethuli ye-ed empilweni yethu yansuku zonke

I-Copper ingenye yezinsimbi eziguquguqukayo emhlabeni. Izakhiwo zayo ezihlukile zikwenza kufanelekile ukuthola izicelo eziningi, kufaka phakathi ukuqina kukagesi. I-Copper isetshenziswa kakhulu kwizimboni zikagesi nakwezogesi, futhi ama-foils ethusi ayizakhi ezibalulekile zokukhiqiza amabhodi wesifunda (ama-PCB). Phakathi kwezinhlobo ezahlukene ze-foils zethusi ezisetshenziselwa ukukhiqizwa kwama-PCB, i-Fropper Foil yiyona esetshenziswa kakhulu.

I-Folip Foil ikhiqizwa yi-Electro-Deposition (ED), okuyinqubo efaka ukubekwa kwama-athomu ethusi e-Metallic ebusweni nge-Electric yamanje. I-foil ye-Copper ephumela iyihlanzekile kakhulu, umfaniswano, futhi inezakhiwo ezinhle kakhulu zemishini kanye nogesi.

Enye yezinzuzo eziphambili ze-Ed Copper Foil ukufana kwayo. Inqubo ye-Electro-Deposition iqinisekisa ukuthi ubukhulu be-foil yethusi bungaguquki kulo lonke umphezulu wayo, obucayi ekukhiqizweni kwe-PCB. Ubukhulu be-Foil ye-Copper ngokuvamile buchazwa ngama-microns, futhi kungasukela kuma-microns ambalwa kuya kumashumi amancane ama-microns, kuya ngohlelo lokusebenza. Ubukhulu be-foil yethusi bunquma ukuqina kwalo kagesi, futhi i-foil enkulu ngokuvamile inokuqhutshwa okuphezulu.

Ngaphezu kokufana kwayo, i-Fopper Foil inezakhiwo ezinhle kakhulu zemishini. Iguquguqukayo kakhulu futhi ingagonywa kalula, yakhiwe futhi yasungulwa ukuze ivumelane ne-contours ye-PCB. Lokhu kuvumelana nalokhu kwenza kube yinto efanelekile yokukhiqiza ama-PCB ane-geometries eyinkimbinkimbi nemiklamo eyinkimbinkimbi. Ngaphezu kwalokho, ukulahleka okuphezulu kwe-foil yethusi kuyakuvumela ukumelana nokugoba okuphindaphindiwe nokuguquguquka ngaphandle kokuqhekeka noma ukuqhekeka.

Enye impahla ebalulekile ye-ed yethusi ye-foil ingukuqhubekela phambili kukagesi. I-Copper ingenye yezinsimbi ezisebenzayo kakhulu, futhi i-foil yethuli ye-ed inokuphakelayo okungaphezulu kwe-5 × 10 ^ 7 s. Lesi sigaba esiphakeme sokuphakelayo sibalulekile ekukhiqizweni kwama-PCB, lapho kunika amandla ukudluliswa kwezimpawu zikagesi phakathi kwezakhi. Ngaphezu kwalokho, ukumelana kukagesi okuphansi kwe-foil yethusi kunciphisa ukulahleka kwamandla wesiginali, okubucayi ngesivinini esikhulu kanye nezinhlelo zokusebenza ezivame kakhulu.

I-Folip Foil ye-Ed futhi imelana kakhulu ne-oxidation kanye nokugqwala. I-Copper iphendula ngo-oksijini emoyeni ukuze kwakheke ungqimba oluncanyana lwe-oxide ekhohlisayo ebusweni bayo, obungahlehlisa ukuvumelanisa kukagesi. Kodwa-ke, i-Folip Foil ehlelekile ihlanganiswe ngengqimba yezinto zokuvikela, ezinjenge-tin noma i-nickel, ukuvikela i-oxidation futhi ithuthukise ukuzungulwa kwayo.

Ekuphetheni, i-Fropper Foil iyindlela ehlukahlukene futhi ebalulekile ekukhiqizweni kwama-PCB. Ukufana kwayo, ukuguquguquka kwayo, ukuqina kukagesi okuphezulu, kanye nokumelana ne-oxidation kanye nokugqwala kwenze kube yinto efanelekile yokukhiqiza ama-PCB ane-geometries eyinkimbinkimbi kanye nezidingo eziphezulu. Ngesidingo esikhulayo sesivinini esiphakeme kanye ne-elekthronikhi ephezulu kakhulu, ukubaluleka kwe-ed Copper Foil kusethelwa kuphela eminyakeni ezayo.
