Kev kho degreasing ntawm Rolled Copper Foil: Cov txheej txheem tseem ceeb thiab kev lees paub tseem ceeb rau txheej txheej thiab thermal lamination Performance

Rolled tooj liab ntawv ciyog cov khoom siv tseem ceeb hauv kev lag luam hauv hluav taws xob, thiab nws qhov chaw thiab kev huv hauv tsev ncaj qha txiav txim siab qhov kev ntseeg siab ntawm cov txheej txheem qis qis xws li txheej txheej thiab thermal lamination. Kab lus no txheeb xyuas cov txheej txheem los ntawm kev kho degreasing optimizes qhov kev ua tau zoo ntawm cov ntawv yob tooj liab los ntawm kev tsim khoom thiab kev xav. Siv cov ntaub ntawv tiag tiag, nws qhia tau tias nws hloov tau mus rau qhov kub thiab txias ua cov xwm txheej. CIVEN METAL tau tsim cov txheej txheem sib sib zog nqus degreasing uas tawg los ntawm kev lag luam cov fwj, muab cov kev ntseeg siab ntawm cov ntawv ci tooj liab rau kev tsim hluav taws xob high-end.

1. Lub hauv paus ntawm cov txheej txheem degreasing: Dual tshem tawm ntawm nto thiab sab hauv roj

1.1 Cov teeb meem roj seem hauv cov txheej txheem Rolling

Thaum lub sij hawm tsim cov ntawv ci tooj liab, tooj liab ingots undergo ntau cov kauj ruam dov los tsim cov ntawv ci. Txhawm rau txo qis kev sib txhuam kub thiab yob hnav, lubricants (xws li cov roj ntxhia thiab hluavtaws esters) yog siv los ntawm cov yob thiabtooj liab ntawv cinto. Txawm li cas los xij, cov txheej txheem no ua rau cov roj khaws cia los ntawm ob txoj hauv kev tseem ceeb:

• Nto adsorption: Nyob rau hauv dov siab, ib tug micron-scale roj zaj duab xis (0.1-0.5μm tuab) adheres rau tooj liab ntawv ci nto.
• Internal nkag: Thaum lub sij hawm dov deformation, tooj liab lattice tsim microscopic defects (xws li dislocations thiab voids), tso cai roj molecules (C12-C18 hydrocarbon chains) nkag mus rau hauv cov ntawv ci los ntawm capillary nkaus, mus txog qhov tob ntawm 1-3μm.

1.2 Cov kev txwv ntawm kev tu ib txwm siv

Cov txheej txheem ntxuav saum npoo (piv txwv li, alkaline ntxuav, dej cawv so) tshem tawm tsuas yog cov roj pleev xim, ua tiav qhov kev tshem tawm txog70-85%, tab sis yog ineffective tiv thaiv internally absorbed roj. Kev sim cov ntaub ntawv qhia tau hais tias tsis muaj kev sib sib zog nqus degreasing, cov roj sab hauv rov tshwm sim tom qab30 feeb ntawm 150 ° C, nrog ib tug re-deposition tus nqi ntawm0.8-1.2g / m², ua rau "thib ob sib kis."

1.3 Technological Breakthroughs hauv Deep Degreasing

CIVEN METAL ntiav ib"Tshuaj extraction + ultrasonic activation"txheej txheem sib xyaw:

1. Tshuaj rho tawm: Tus neeg saib xyuas kev cai (pH 9.5-10.5) decomposes ntev-chain roj molecules, tsim cov dej-soluble complexes.
2. Ultrasonic kev pab: 40kHz high-frequency ultrasound generates cavitation los, rhuav lub binding quab yuam ntawm sab hauv roj thiab cov tooj liab lattice, txhim khu cov roj dissolution efficiency.
3. Nqus kom qhuav: Lub cev qhuav dej sai ntawm -0.08MPa tsis zoo siab tiv thaiv oxidation.

Cov txheej txheem no txo ​​cov roj residue rau≤ 5mg / m²(raws li IPC-4562 tus qauv ntawm ≤15mg / m²), ua tiav> 99% tshem tawm efficiencyrau sab hauv absorbed roj.

2. Kev cuam tshuam ncaj qha ntawm kev kho degreasing ntawm txheej txheej thiab thermal lamination txheej txheem

2.1 Adhesion Enhancement nyob rau hauv daim ntawv thov txheej

Cov ntaub ntawv txheej (xws li PI adhesives thiab photoresists) yuav tsum tsim cov molecular-theem bonds nrogtooj liab ntawv ci. Residual roj ua rau cov teeb meem hauv qab no:

• Txo lub zog interfacial: Lub hydrophobicity ntawm roj nce lub kaum sab xis ntawm cov txheej txheem daws los ntawm15 ° txog 45 °, cuam tshuam kev ntub dej.
• Inhibited chemical bonding: Cov roj txheej thaiv cov pawg hydroxyl (-OH) ntawm cov tooj liab, tiv thaiv kev cuam tshuam nrog cov pab pawg resin nquag.

Kev sib piv ntawm Degreased vs. Regular Copper Foil:

2.2 Txhim kho kev ntseeg siab hauv Thermal Lamination

Thaum lub sij hawm kub-kub lamination (180-220 ° C), roj residual hauv cov ntawv ci tooj liab ua rau ntau qhov ua tsis tiav:

• Ua npuas ncauj: Vaporized roj tsim10-50μm npuas(qhov ceev> 50 / cm²).
• Interlayer delamination: Roj txo van der Waals rog ntawm epoxy resin thiab tooj liab ntawv ci, txo tev lub zog los ntawm30-40%.
• Dielectric poob: Dawb roj ua rau dielectric qhov hloov pauv (Dk variation> 0.2).

Tom qab1000 teev ntawm 85 ° C / 85% RH laus, CIVEN METALCopper Foilkhoom pov thawj:

• npuas ntom: <5/cm² (kev lag luam nruab nrab> 30/cm²).
• Peel zog: Khaws1.6 N / cm(tus nqi pib1.8 N / cm, degradation tus nqi tsuas yog 11%).
• Dielectric stability: Dk variation ≤0.05, kev sib ntsib5G millimeter-yoj zaus yuav tsum.

3. Kev Lag Luam Status thiab CIVEN METAL's Benchmark Position

3.1 Kev Sib Tw Kev Lag Luam: Tus Nqi-Driven Txheej Txheem Simplification

Tshaj90% ntawm dov tooj liab ntawv ci manufacturersua kom yooj yim rau kev txiav cov nqi, ua raws li kev ua haujlwm yooj yim:

Rolling → Dej Ntxuav (Na₂CO₃ tov) → ziab → Winding

Txoj kev no tsuas yog tshem tawm cov roj saum npoo av, nrog rau tom qab ntxuav qhov chaw tiv thaiv kev hloov pauv ntawm± 15%(CIVEN METAL tus txheej txheem tswj nyob rau hauv± 3%).

3.2 CIVEN METAL's "Zero-Defect" Kev Tswj Xyuas Zoo

• Kev saib xyuas online: X-ray fluorescence (XRF) tsom xam rau lub sij hawm tshawb pom ntawm cov khoom seem seem (S, Cl, thiab lwm yam).
• Accelerated aging tests: Simulating heev200 ° C / 24 teevtej yam kev mob los xyuas kom meej xoom roj rov tshwm sim.
• Tag nrho cov txheej txheem traceability: Txhua yob suav nrog QR code txuas rau32 cov txheej txheem tseem ceeb(piv txwv li, degreasing kub, ultrasonic zog).

4. Xaus: Degreasing Treatment—Lub Foundation ntawm High-End Electronics Manufacturing

Kev sib sib zog nqus degreasing ntawm dov tooj liab ntawv ci tsis yog ib qho kev hloov kho tshiab xwb tab sis kev xav txog kev hloov mus rau yav tom ntej. CIVEN METAL's breakthrough technology txhim kho cov ntawv ci tooj liab kom huv si rau qib atomic, muabkhoom-theem kev ruaj ntsegrauHigh-density interconnects (HDI), automotive hloov pauv circuits, thiab lwm yam high-end teb.

Hauv5G thiab AIoT era, tsuas yog tuam txhab uas muag masteringcore tu technologiestuaj yeem tsav cov kev tsim kho tshiab yav tom ntej hauv kev lag luam hluav taws xob tooj liab.
