CNZHJ's copper foil ine yakanakisa magetsi conductivity, kuchena kwepamusoro, kurongeka kwakanaka, kushomeka oxidation, yakanaka makemikari kuramba, uye nyore etching. Panguva imwecheteyo, kuitira kuti isangane nezvinodiwa zvekugadzirisa zvevatengi vakasiyana, CNZHJ inogona kucheka foil yemhangura mumashiti, iyo inogona kuchengetedza vatengi mari yakawanda yekugadzirisa.
Themufananidzo wekuonekwayefoiri yemhangura uye inoenderana neelectronic microscope scanning picture ndeaya anotevera:
Ukobvu uye uremu hwemhangura foil(Yakatorwa kubva kuIPC-4562A)
Hukobvu hwemhangura hwePCB copper-clad board kazhinji hunoratidzwa muimperial ounces (oz), 1oz=28.3g, senge 1/2oz, 3/4oz, 1oz, 2oz. Semuenzaniso, huwandu hwenzvimbo ye1oz/ft² hwakaenzana ne305 g/㎡ mumametric units. , yakashandurwa necopper density (8.93 g/cm²), yakaenzana nehukobvu hwe34.3um.
Tsanangudzo yemhangura yemhangura "1/1": foil yemhangura ine nzvimbo ye 1 square foot uye uremu hwe1 ounce; kuparadzira 1 ounce yemhangura zvakaenzana pandiro ine nzvimbo ye 1 square foot.
Ukobvu uye uremu hwemhangura foil
☞ED, Electrodeposited copper foil (ED copper foil), zvinoreva foil yemhangura yakagadzirwa neelectrodeposition. Iyo nzira yekugadzira ndeye electrolysis process. Electrolysis midziyo inowanzo shandisa roller yepamusoro yakagadzirwa netitanium zvinhu se cathode roller, yepamusoro soluble lead-based alloy kana isingagadzike titanium-based corrosion-resistant coating seanode, uye sulfuric acid inowedzerwa pakati pecathode uye anode. Copper electrolyte, pasi pekuita kweyakananga ikozvino, ine simbi yemhangura ions yakashambadzirwa pane cathode roller kuti igadzire electrolytic yepakutanga foil. Sezvo iyo cathode roller ichiramba ichitenderera, iyo yakagadzirwa yepakutanga foil inoramba ichishambadzirwa uye yakapepetwa paroller. Zvadaro inogezwa, yoomeswa, uye yoiswa mupumburu wefoiri mbishi. Iyo yemhangura foil kuchena ndeye 99.8%.
☞RA, Yakakungurutswa annealed copper foil, inotorwa kubva mumhangura ore kugadzira blister mhangura, iyo inonyungudutswa, inogadziriswa, inonatswa nemagetsi, uye inogadzirwa kuita ingots dzemhangura dzinenge 2mm gobvu. Iyo ingot yemhangura inoshandiswa seyakagadzika zvinhu, iyo yakanyungudutswa, yakasvibiswa, uye inopisa-yakakungurutswa uye yakakungurutswa (mune nzira refu) pakudziya kwepamusoro pe800 ° C kwenguva dzakawanda. Kuchena 99.9%.
☞HTE, tembiricha yakakwira elongation electrodeposited copper foil, ifoiri yemhangura inochengetedza kurebesa kwakanyanya pakudziya kwepamusoro (180°C). Pakati pavo, kurebesa kwefoiri yemhangura ine ukobvu hwe35μm uye 70μm pakupisa kwepamusoro (180 ℃) kunofanirwa kuchengetedzwa kune inopfuura 30% yehuremu pakudziya kwekamuri. Iyo inonziwo HD copper foil (yakakwirira ductility copper foil).
☞DST, kaviri padivi kurapwa foil yemhangura, inoomesa zvese zviri zviviri zvakatsetseka uye zvakakasharara nzvimbo. Chinangwa chikuru chezvino ndechekuderedza mari. Roughening yakatsetseka pamusoro anogona kuchengetedza mhangura pamusoro kurapwa uye browning matanho asati lamination. Inogona kushandiswa seyemukati mutsetse wemhangura foil kune akawanda-layer mapuranga, uye haidi kuve yakasvibira (yakasviba) isati yaturika mabhodhi akawanda-layer. Izvo zvisingabatsiri ndezvokuti nzvimbo yemhangura haifaniri kucheneswa, uye zvakaoma kubvisa kana pane kusvibiswa. Parizvino, kushandiswa kwekaviri-sided yakarapwa foil yemhangura iri kuderera zvishoma nezvishoma.
☞UTF, yakanyanyisa kutetepa foil yemhangura, inoreva foil yemhangura ine ukobvu isingasviki 12μm. Anonyanya kuzivikanwa mapepi emhangura ari pasi pe9μm, ayo anoshandiswa pamabhodhi edunhu akadhindwa ekugadzira maseketi akanaka. Nekuti yakanyanya kutetepa foil yemhangura inonetsa kubata, inowanzo tsigirwa nemutakuri. Mhando dzevatakuri dzinosanganisira foil yemhangura, aluminium foil, organic film, nezvimwe.
