Kugadzira Nemazvo uye Kushandiswa Kwakagadziriswa kweRolled Copper Foil — Kubva Pakuongorora Maitiro Kusvika Pakusimudzira Maindasitiri

Foiri yemhangura yakamonerwainoita basa rakakosha mumaindasitiri epamusoro akadai semasekete emagetsi, mabhatiri matsva esimba, uye kudzivirirwa kwemagetsi. Kushanda kwayo uye kuvimbika kwayo kunoenderana nekunyatsoita kwayo kugadzirwa uye kugona kwayo kugadzirisa. Chinyorwa chino chinoongorora rwendo rwakazara rwekugadzira rolledfoil yemhangurakubva pamaonero ehunyanzvi uye inotsanangura kuti inosimudzira sei maindasitiri emazuva ano kuburikidza nemhinduro dzakagadzirirwa ivo.

I. Maitiro Ekugadzira Akajairika: Kuenzanisa Kururama uye Kushanda Zvakanaka

1. Kukanda Ingot Yemhangura: Nzvimbo Yekutanga Yekuchena Nemaumbirwo
Uchishandisa mhangura yemagetsi yakachena kwazvo (≥99.99%), chinhu chacho chinonyungudutswa ne vacuum uye chinokandwa nguva dzose muma ingots ane ukobvu hwe 100–200mm. Mwero wekutonhodza unodzorwa zvakasimba kuitira kuti zvive zvakanaka, zvakaenzana uye kudzivirira kutsemuka panguva yekumonera kunotevera.

2. Kutenderedza Kunopisa: Danho rekutanga rekuderedza ukobvu
Ma ingts emhangura anomonerwa nekupisa kusvika pa5–10mm pa700–900°C achishandisa chigayo chinodzoserwa. Kuzora kwakasimba kunoderedza kupera kweroller uye kunoderedza kushushikana kwemukati kubva mukukanda, zvichiisa hwaro hwekumonera kwakanyatsonaka.

3. Kuunganidza: Kuchenesa uye Kushanda Pamusoro
Musanganiswa we nitric-sulfuric acid (10–15% concentration) unoshandiswa kubvisa oxidation. Kurapa ne electro-polishing kunoderedza surface roughness (Ra) kusvika pasi pe 0.2μm, zvichiita kuti pave nemigumisiro yakanaka pakuenderera mberi nekutenderera.

4. Kutenderera Kwakarurama: Kuzadzisa Kururama kweMakironi
Kupfuura nepakati pema "cold-rolling" kunoderedza mhangura kusvika pa 0.1–0.2mm. Ne "high-rigidity mills" uye "laser thickness gauges" (±2μm accuracy), kusiyana kwehukobvu kunochengetwa mukati me 1%. Simba rekutenderera nekumanikidzwa zvinodzorwa nokungwarira kudzivirira kutsemuka kwemucheto.

5. Kutenderedza Foil: Kugadzira Nzvimbo Dzakatetepa Zvikuru
Zvigayo zvemafoil zvemhando yepamusoro zvinoshandisa micro-gap adjustment uye oil-film lubrication kuti zvisvike pakukora kwe9–90μm. Kupenya kwepamusoro kunodarika ISO 1302 grade 12, kwakakodzera kushandiswa kwe5G high-frequency skin effect.

6. Kubvisa mafuta: Danho rekupedzisira rekuchenesa pamusoro
Kuchenesa kwe ultrasonic pamwe chete ne alkaline degreasing (pH 11–13) kunobvisa mafuta anotenderera akasara. Carbon residue inodzorwa pasi pe 5mg/m², zvichiita kuti pave nehwaro hwakachena hwekugadzirisa pamusoro.

7. Kucheka nekuisa zvinhu muzvikamu: Kunyatsogadzirwa kweindasitiri nerunako rwemhando yepamusoro
Mapadza akaputirwa nedhaimani anokwana ±0.1mm pakureba. Zvigadzirwa zvinoputirwa mufirimu rekudzivirira oxidation uye zvinochengetwa mumamiriro ekunze anodzora (25±2°C, ≤70% RH) kuitira kuti zvinhu zvirambe zvakanaka.

II. Kugadziriswa Kwakakodzera: Kuvandudza Mashandiro Akanangana Neindasitiri

1. Annealing: Kugadzirisa Zvimiro zveMichina

Hasha Dzakapfava (O):Yakavharirwa pa400–600°C pasi pemhepo yeH₂/N₂ kwemaawa 2–4. Simba rekudhonza rinodzikira kusvika pa200–250MPa uye kureba kunokwira kusvika pa25–40%, zvakanakira kukotama kwesimba remuchina weflex circuit.

Hasha Dzakaoma (H):Inoramba iine simba rakasimba (400–500MPa), ichivimbisa kugadzikana kwezvikamu zveIC.

2. Kurapa Pamusoro: Kuvandudzwa Kwebasa

Kukwesha:Kucheka kwemakemikari kunoumba mapundu e1–2μm, zvichiwedzera kunamira kwe resin ku1.5N/mm kana kupfuura—kugadzirisa matambudziko ekubvisa maburi mumabhodhi e5G.

Kuisa Nickel/Tin:Mapendi e 0.1–0.3μm anopa simba rekudzivirira ngura re 10×, akakodzera ma EV battery tabs.

Kupfeka Kwekupisa Kwakanyanya:Kuputira neZn nano-coating kunochengetedza kugadzikana kwefoil pa300°C, zvichizadzisa zvinodiwa zvewaya dzemuchadenga.

III. Kupa Maindasitiri Akakosha Simba kuburikidza neKuvandudza Maitiro

Zvemagetsi:Foil ye9μm yakabatana ne roughening inogonesa HDI board line rowths pasi pe12μm, zvichibatsira smartphone miniaturization.

Mabhatiri emagetsi:Foil ine hunyoro hwakapfava ine kureba kwe ≥20% inogona kugara kwenguva dzinopfuura 3000 dzenzeve, zvichiita kuti bhatiri rive rakavimbika.

Kudzivirira EMI:Foil ine nickel-plated inoita kuti 120dB zivivirwe pa10GHz, iyo yakakodzera nzvimbo dzedata.

IV. CIVEN METAL: Kuisa Standard muCustom Copper Foil Solutions

Semutungamiri mufoiri yemhangura yakakungurutswakugadzira,Simbi yeCIVENyakagadzira sisitimu yekugadzira inochinjika inosanganisa maitiro akajairwa nemaitiro ekugadzirisa emodular:

Maworkshop akachena zvakanyanya uye kudzorwa kweMES kunogonesa ±2μm ukobvu uye kutsetseka ≤1I.

Zvitofu zvinogadziriswa zvinogadziriswa zvinobata kusvika ku20 maodha akasiyana panguva imwe chete.

"Raibhurari yekurapa pamusoro" yemunhu inosanganisira mhando gumi nembiri dzekukwesha uye sarudzo sere dzekushandisa electroplating, ine maawa makumi manomwe nemaviri ekupindura.

Kugadzirisa mashandiro uye kuwana zvinhu zvakawanda zvinoderedza mitengo yefoil yakagadzirwa nevatengi ne15–20% zvichienzaniswa neavhareji yemusika.

Kubva pama ingots ane saizi ye millimeter kusvika pama foil akatetepa-micron, kugadzira ma foil emhangura akamoneredzwa mutambo wesainzi yezvinhu uye mainjiniya ekugadzirisa. Sezvo shanduko dze5G nesimba dzichiitika, makambani chete anosanganisa kunyatsorongeka kwakajairika nekugadzirisa kwakadzama ndiwo anogona kuramba ari pamberi.Simbi yeCIVENari kutungamira shanduko iyi, achibatsira Chinafoil yemhanguraindasitiri iri kukwira zvakanyanya mudungwe wezvinhu zvinokosha pasi rose.
