1.Umlando Wokuthuthukiswa Kwe-Copper Foil
Umlando weucwecwe lwethusiingalandelelwa emuva kuma-1930s, lapho umsunguli waseMelika u-Thomas Edison esungula ilungelo lobunikazi lokwenziwa okuqhubekayo kwe-foil yensimbi encane, eyaba iphayona lobuchwepheshe besimanje be-electrolytic copper foil. Kamuva, i-Japan yethula futhi yathuthukisa lobu buchwepheshe ngeminyaka yawo-1960, futhi i-China yazuza ukukhiqizwa okukhulu okuqhubekayo kwe-foil yethusi ekuqaleni kwawo-1970.
2.Ukuhlukaniswa kwe-foil yethusi
I-copper foilihlukaniswe ngokuyinhloko izigaba ezimbili: ucwecwe lwethusi olugoqiwe (RA) kanye nocwecwe lwethusi lwe-electrolytic (ED).
I-foil yethusi egoqiwe:eyenziwe ngezindlela ezingokomzimba, ezinobuso obushelelezi, i-conductivity enhle kakhulu kanye nezindleko eziphezulu.
I-Electrolytic copper foil:eyenziwe nge-electrolytic deposition, enezindleko eziphansi, futhi ingumkhiqizo ojwayelekile emakethe.
Phakathi kwazo, ucwecwe lwethusi lwe-electrolytic lungabuye luhlukaniswe lube izinhlobo eziningi ukuze kuhlangatshezwane nezidingo ezahlukahlukene zohlelo lokusebenza:
●HTE icwecwe lethusi:ukumelana nokushisa okuphezulu, i-ductility ephezulu, ifanele amabhodi e-PCB anezingqimba eziningi, njengamaseva asebenza kahle kakhulu kanye nemishini ye-avionics.
Ikesi: Amaseva e-Inspur Information asebenza kahle kakhulu asebenzisa ucwecwe lwethusi lwe-HTE ukuze abhekane nokuphathwa okushisayo kanye nezinkinga zobuqotho besignali kukhompyutha esebenza kahle kakhulu.
●I-RTF ye-copper foil:Ithuthukisa ukunamathela phakathi kwe-copper foil kanye ne-insulating substrate, evame ukusetshenziswa kumayunithi okulawula ugesi wezimoto.
Icala: Isistimu yokuphatha ibhethri ye-CATL isebenzisa i-RTF ye-copper foil ukuqinisekisa ukwethembeka nokuzinza ngaphansi kwezimo ezimbi kakhulu.
● I-ULP ye-copper foil:iphrofayili ephansi kakhulu, enciphisa ukujiya kwamabhodi e-PCB, afanele imikhiqizo emincane ye-elekthronikhi efana nama-smartphone.
Ikesi: I-motherboard ye-smartphone ye-Xiaomi isebenzisa i-ULP ye-copper foil ukuze ithole idizayini elula nencane.
● I-copper foil ye-HVLP:i-high-frequency ultra-low profile foil yethusi, yaziswa kakhulu imakethe ngokusebenza kwayo okuhle kakhulu kokudlulisa isignali. Inezinzuzo zobulukhuni obuphezulu, indawo ebushelelezi eqinile, ukuzinza okuhle kokushisa, ukujiya okufanayo, njll., okunganciphisa ukulahlekelwa kwesignali emikhiqizweni ye-elekthronikhi. Isetshenziselwa amabhodi we-PCB wokudlulisela ngesivinini esiphezulu njengamaseva aphezulu kanye nezikhungo zedatha.
Icala: Muva nje, i-Solus Advanced Materials, omunye wabahlinzeki be-Nvidia abayinhloko be-CCL eSouth Korea, ithole ilayisense yokugcina yokukhiqiza ngobuningi be-Nvidia futhi izohlinzeka nge-HVLP i-copper foil ku-Doosan Electronics ukuze isetshenziswe esizukulwaneni esisha se-Nvidia se-AI accelerator uNvidia ahlela ukuyethula kulo nyaka.
3.Izimboni zezicelo namacala
●Printed Circuit Board (PCB)
I-copper foil, njengongqimba olusebenzayo lwe-PCB, luyingxenye ebalulekile yezinto zikagesi.
Ikesi: Ibhodi le-PCB elisetshenziswa kuseva ye-Huawei liqukethe i-foil yethusi enembayo ephezulu ukuze kuzuzwe umklamo oyinkimbinkimbi wesekethe kanye nokucubungula idatha ngesivinini esikhulu.
●Ibhethri ye-lithium-ion
Njengomqoqi wamanje we-electrode engalungile, ucwecwe lwethusi ludlala indima ebalulekile ebhethrini.
Ikesi: Ibhethri ye-lithium-ion ye-CATL isebenzisa ucwecwe lwethusi lwe-electrolytic olusebenza kakhulu, oluthuthukisa ukuminyana kwamandla ebhethri nokushaja nokusebenza kahle kokukhipha.
●I-Electromagnetic Shielding
Emishinini yezokwelapha ye-MRI kanye neziteshi eziyisisekelo zokuxhumana, i-copper foil isetshenziselwa ukuvikela ukuphazamiseka kukagesi.
Ikesi: Imishini ye-MRI ye-United Imaging Medical isebenzisa i-copper foil ukuvikela ugesi, iqinisekisa ukucaca nokunemba kwesithombe.
● Ibhodi Lesifunda Eliphrintiwe Eliguquguqukayo
I-foil yethusi egoqiwe ifaneleka kumadivayisi kagesi agobekayo ngenxa yokuguquguquka kwayo.
Ikesi: I-Xiaomi wristband isebenzisa i-PCB eguquguqukayo, lapho i-copper foil inikeza indlela edingekayo yokuqondisa ngenkathi igcina ukuguquguquka kwedivayisi.
