1. Mbiri Yachitukuko cha Copper Foil
Mbiri yazojambula zamkuwazitha kuyambika m'zaka za m'ma 1930, pomwe woyambitsa waku America a Thomas Edison adapanga chivomerezo chopanga mosalekeza kupanga zojambula zachitsulo zopyapyala, zomwe zidakhala mpainiya waukadaulo wamakono wa electrolytic copper foil. Pambuyo pake, Japan idayambitsa ndi kupanga ukadaulo uwu m'zaka za m'ma 1960, ndipo China idakwanitsa kupanga zojambula zamkuwa koyambirira kwa zaka za m'ma 1970.
2.Kupanga zojambula zamkuwa
Chojambula chamkuwaamagawidwa m'magulu awiri: zojambulazo zamkuwa (RA) ndi zojambula zamkuwa za electrolytic (ED).
Zojambula za Copper:zopangidwa ndi njira zakuthupi, zosalala pamwamba, conductivity zabwino kwambiri komanso mtengo wokwera.
Chojambula chamkuwa cha Electrolytic:zopangidwa ndi electrolytic deposition, zotsika mtengo, ndipo ndiye chinthu chachikulu pamsika.
Mwa iwo, zojambula zamkuwa za electrolytic zitha kugawidwa m'mitundu ingapo kuti zikwaniritse zosowa zosiyanasiyana:
● Chojambula chamkuwa cha HTE:kutentha kwambiri kukana, ductility mkulu, oyenera Mipikisano wosanjikiza matabwa PCB, monga mkulu-ntchito maseva ndi zipangizo avionics.
Mlandu: Ma seva ochita bwino kwambiri a Inspur Information amagwiritsa ntchito zojambula zamkuwa za HTE kuti athane ndi kasamalidwe ka kutentha ndi nkhani za kukhulupirika pamakompyuta ochita bwino kwambiri.
● zojambula zamkuwa za RTF:Imawongolera kumamatira pakati pa zojambulazo zamkuwa ndi gawo lapansi lotsekera, lomwe limagwiritsidwa ntchito kwambiri pamagawo owongolera zamagetsi pamagalimoto.
Mlandu: Makina oyang'anira mabatire a CATL amagwiritsa ntchito zojambula zamkuwa za RTF kuti zitsimikizire kudalirika komanso kukhazikika pansi pamikhalidwe yovuta kwambiri.
● Chojambula chamkuwa cha ULP:mbiri yotsika kwambiri, kuchepetsa makulidwe a matabwa a PCB, oyenera kuzinthu zamagetsi zamagetsi monga mafoni a m'manja.
Mlandu: Bokosi la ma smartphone la Xiaomi limagwiritsa ntchito zojambula zamkuwa za ULP kuti apange mawonekedwe opepuka komanso owonda.
● Chojambula chamkuwa cha HVLP:high-frequency ultra-low profile copper copper, imayamikiridwa kwambiri ndi msika chifukwa cha machitidwe ake abwino otumizira ma siginecha. Lili ndi ubwino waukulu kuuma, yosalala roughened pamwamba, wabwino matenthedwe bata, makulidwe yunifolomu, etc., amene angachepetse chizindikiro imfa mu mankhwala amagetsi. Izo ntchito mkulu-liwiro kufala matabwa PCB monga maseva apamwamba-mapeto ndi malo deta.
Mlandu: Posachedwapa, Solus Advanced Materials, m'modzi mwa ogulitsa kwambiri a CCL ku Nvidia ku South Korea, adalandira chilolezo chomaliza cha Nvidia ndipo adzapereka zojambula zamkuwa za HVLP ku Doosan Electronics kuti zigwiritsidwe ntchito mumbadwo watsopano wa Nvidia wa AI accelerators omwe Nvidia akukonzekera kukhazikitsa chaka chino.
3.Mafakitale ofunsira ndi milandu
●Printed Circuit Board (PCB)
Chojambula chamkuwa, monga conductive wosanjikiza wa PCB, ndi mbali yofunika kwambiri pa zipangizo zamagetsi.
Mlandu: Bolodi la PCB lomwe limagwiritsidwa ntchito mu seva ya Huawei lili ndi zojambulazo zamkuwa zapamwamba kwambiri kuti zikwaniritse mapangidwe ovuta a dera komanso kukonza kwa data mwachangu.
● Batri ya lithiamu-ion
Monga chotolera chamakono cha electrode, zojambula zamkuwa zimagwira ntchito yofunika kwambiri mu batri.
Mlandu: Battery ya lithiamu-ion ya CATL imagwiritsa ntchito zojambulazo zamkuwa za electrolytic, zomwe zimathandizira kachulukidwe wamagetsi a batri ndi kuchuluka kwake komanso kutulutsa bwino.
● Electromagnetic Shielding
M'makina azachipatala a MRI ndi malo olumikizirana, zojambula zamkuwa zimagwiritsidwa ntchito kuteteza kusokoneza kwamagetsi.
Mlandu: Zida za MRI za United Imaging Medical zimagwiritsa ntchito zojambulazo za mkuwa potchingira ma electromagnetic shielding, kuwonetsetsa kumveka bwino komanso kulondola kwa kujambula.
● Flexible Printed Circuit Board
Chojambula chamkuwa chopukutidwa ndi choyenera pazida zamagetsi zopindika chifukwa cha kusinthasintha kwake.
Mlandu: Xiaomi wristband imagwiritsa ntchito PCB yosinthika, pomwe zojambulazo zamkuwa zimapereka njira yoyendetsera bwino ndikusunga kusinthasintha kwa chipangizocho.
● Consumer electronics, makompyuta ndi zipangizo zina
Zojambula za Copper zimagwira ntchito yofunika kwambiri m'mabodi am'manja a zida monga mafoni am'manja ndi laputopu.
Mlandu: Ma laputopu a Huawei a MateBook amagwiritsa ntchito zojambula zamkuwa zowoneka bwino kuti zitsimikizire kuti chipangizocho chimagwira ntchito bwino komanso chodalirika.
● Zamagetsi zamagalimoto M'magalimoto amakono
zojambula zamkuwa zimagwiritsidwa ntchito pazinthu zazikulu zamagetsi monga mayunitsi owongolera injini ndi kasamalidwe ka batri.
Mlandu: Magalimoto amagetsi a Weilai amagwiritsa ntchito zojambulazo zamkuwa kuti azitha kuyendetsa bwino batire komanso chitetezo.
● Pazida zoyankhulirana monga masiteshoni a 5G ndi ma routers
zojambulazo zamkuwa zimagwiritsidwa ntchito kuti zitheke kufalitsa deta mwachangu kwambiri.
Mlandu: Zida zoyambira za Huawei za 5G zimagwiritsa ntchito zojambula zamkuwa zowoneka bwino kwambiri kuti zithandizire kutumiza ndi kukonza data mwachangu.
