Degreasing Kurapwa kweRolled Copper Foil: Core process uye Kiyi Simbiso yeCoating uye Thermal Lamination Performance.

Yakakungurutswa yemhangura foilchinhu chakakosha muindasitiri yedunhu remagetsi, uye kuchena kwayo kwemukati uye kwemukati kunotaridza kuvimbika kwemaitiro ekudzika senge coating uye thermal lamination. Ichi chinyorwa chinoongorora magadzirirwo ayo kurapa kwekudzikisa kunonatsiridza mashandiro emhangura yakakungurutswa foil kubva kune ese ekugadzira uye mashandisiro maonero. Kushandisa data chaiyo, inoratidza kuchinjika kwayo kune yakakwirira-tembiricha yekugadzirisa mamiriro. CIVEN METAL yakagadzira proprietary yakadzika degreasing process iyo inotyora kuburikidza neindasitiri mabhodhoro, ichipa yakakwirira-yakavimbika mhangura foil mhinduro dzepamusoro-kuguma kwemagetsi kugadzira.

1. Nheyo yeKuderedza Maitiro: Kubvisa Kaviri Kwepamusoro uye Mukati Girisi

1.1 Residual Oiri Nyaya muRolling process

Munguva yekugadzirwa kwefoiri yemhangura yakakungurutswa, ingots dzemhangura dzinopinda nhanho dzakawanda dzekukunguruka kugadzira foil zvinhu. Kudzikisira kupisa kwekupisa uye kupfeka kwema roll, mafuta ekuzora (akadai semamineral oils uye synthetic esters) anoshandiswa pakati pemapumburu uyefoil yemhangurapamusoro. Nekudaro, iyi nzira inotungamira mukuchengetwa kwegirisi kuburikidza nenzira mbiri dzekutanga:

• Surface adsorption: Pasi pekumanikidzika, firimu remafuta remicron-scale (0.1-0.5μm gobvu) rinonamatira kune yemhangura foil pamusoro.
• Kupinda mukati: Panguva yekutenderera deformation, iyo yemhangura yemhangura inogadzira microscopic defects (yakadai se dislocation uye voids), ichibvumira grease molecules (C12-C18 hydrocarbon cheni) kupinda mukati foil kuburikidza capillary chiito, kusvika pakadzika 1-3μm.

1.2 Kuganhurirwa kweNzira dzechinyakare dzekuchenesa

Nzira dzakajairwa dzekuchenesa pamusoro (semuenzaniso, kugeza alkaline, kupukuta doro) bvisa chete mafirimu emafuta epamusoro, uchiwana chiyero chekubvisa chingangoita.70-85%, asi haashande pakurwisa girizi inonyudzwa mukati. Yekuedza data inoratidza kuti pasina kudzika kwakadzika, girisi yemukati inobudazve pamusoro pepamusoro mushureBika kwemaminitsi makumi matatu pa 150 ° C, ine re-deposition rate ye0.8-1.2g/m², zvichikonzera "kusvibiswa kwechipiri."

1.3 Mabudiro eTekinoroji muKudzikisira Kwakadzika

CIVEN METAL inoshandisa a"makemikari kudhirowa + ultrasonic activation"composite process:

1. Kutorwa kwemakemikari: Tsika chelating agent (pH 9.5-10.5) inoparadza mamorekuru marefu-chain grease, achigadzira ma-soluble complexes emvura.
2. Ultrasonic rubatsiro: 40kHz yakakwira-frequency ultrasound inogadzira cavitation mhedzisiro, kutyora simba rinosunga pakati pegirisi yemukati nemhangura lattice, kuwedzera girisi kupera simba.
3. Vacuum drying: Kukurumidza kupera mvura mumuviri pa -0.08MPa kudzvinyirira kwakashata kunodzivirira oxidation.

Iyi nzira inoderedza mafuta akasara kune≤5mg/m²(kusangana neIPC-4562 zviyero zve ≤15mg/m²), kubudirira> 99% kubvisa kushanda zvakanakayegirisi inobatwa nemukati.

2. Yakananga Impact yeDegreasing Kurapa pane Coating uye Thermal Lamination Maitiro

2.1 Kuwedzeredzwa kwekunamira muCoating Application

Coating zvinhu (zvakadai sePI adhesives uye photoresists) inofanira kuumba mamolecular-level bond nefoil yemhangura. Residual grease inotungamira kune zvinotevera nyaya:

• Yakaderedzwa interface simba: Iyo hydrophobicity yegirizi inowedzera iyo yekubata kona yeaya yekuputira mhinduro kubva15 ° kusvika 45 °, kutadzisa weti.
• Inhibited chemical bonding: Iyo grease layer inovhara hydroxyl (-OH) mapoka pamusoro pemhangura, kudzivirira maitiro nemapoka anoshanda eresin.

Performance Kuenzanisa kweDegreased vs. Regular Copper Foil:

2.2 Kuvimbika Kwakawedzerwa muThermal Lamination

Munguva yekupisa kwepamusoro-tembiricha (180-220 ° C), girisi yakasara mune yakajairwa foil yemhangura inotungamira mukukundikana kwakawanda:

• Bubble kuumbwa: vaporized girisi inogadzira10-50μm mabhuru(density> 50/cm²).
• Interlayer delamination: Girisi inoderedza masimba evan der Waals pakati peepoxy resin uye foil yemhangura, inoderedza simba reganda ne30-40%.
• Dielectric kurasikirwa: Girisi yemahara inokonzera dielectric inogara ichichinja (Dk musiyano> 0.2).

Mushure1000 maawa e85°C/85% RH kuchembera, CIVEN METALCopper Foilzviratidzo:

• Bubble density: <5/cm² (indasitiri avhareji> 30/cm²).
• Peel simba: Anochengeta1.6N/cm(yekutanga kukosha1.8N/cm, degradation rate chete 11%).
• Dielectric kugadzikana: Dk musiyano ≤0.05, musangano5G millimeter-wave frequency zvinodiwa.

3. Indasitiri Mamiriro uye CIVEN METAL's Benchmark Position

3.1 Zvinetso zveIndasitiri: Mutengo-Unotyairwa Maitiro Kurerutsa

Over90% yevagadziri vemhangura yakakungurutswakurerutsa kugadzirisa kudzikisa mitengo, uchitevera a basic workflow:

Kukunguruka → Wachisa Mvura (Na₂CO₃ mhinduro) → Kuomesa → Kupeta

Iyi nzira inongobvisa girisi yepamusoro, ine post-wash surface resistivity fluctuations ye±15%(CIVEN METAL's process inochengetedza mukati±3%).

3.2 CIVEN METAL's "Zero-Defect" Quality Control System

• Online monitoring: X-ray fluorescence (XRF) kuongororwa kwechokwadi-nguva yekuonekwa kwezvinhu zvakasara zvepasi (S, Cl, nezvimwewo).
• Kukurumidza kuchembera bvunzo: Kutevedzera zvakanyanyisa200°C/24hmamiriro ekuita kuti zero girisi ibude zvakare.
• Yakazara-maitiro traceability: Imwe neimwe roll inosanganisira QR kodhi inobatanidza nayo32 key process parameters(semuenzaniso, kupisa kwekushisa, simba re ultrasonic).

4. Mhedziso: Degreasing Treatment-The Foundation of High-End Electronics Manufacturing

Deep degreasing kurapwa kwefoiri yemhangura yakakungurutswa haingori nzira yekusimudzira asi yekumberi-kufunga kugadzirisa kune ramangwana maapplication. CIVEN METAL yekubudirira tekinoroji inosimudzira kuchena kwemhangura foil kusvika padanho reatomu, ichipa.simbisiro yezvinhunokutihigh-density interconnects (HDI), mota flexible circuits, nemimwe minda yepamusoro.

Mu5G uye AIoT nguva, makambani chete ari kugonacore cleaning technologiesinogona kutyaira hunyanzvi hweramangwana muindasitiri yemagetsi copper foil.
