Kev Kho Mob Degreasing ntawm Cov Ntawv Nyiaj Tooj Liab: Cov Txheej Txheem Tseem Ceeb thiab Kev Paub Tseeb Tseem Ceeb rau Kev Txheej Txheem thiab Kev Ua Haujlwm Thermal Lamination

Cov ntawv ci tooj liab dovyog ib qho khoom siv tseem ceeb hauv kev lag luam hluav taws xob, thiab nws qhov chaw thiab sab hauv huv si ncaj qha txiav txim siab qhov kev ntseeg siab ntawm cov txheej txheem downstream xws li txheej thiab thermal lamination. Tsab xov xwm no tshuaj xyuas cov txheej txheem uas kev kho degreasing ua kom zoo dua qhov kev ua tau zoo ntawm cov ntawv ci tooj liab dov los ntawm ob qho tib si kev tsim khoom thiab kev siv. Siv cov ntaub ntawv tiag tiag, nws qhia txog nws qhov kev hloov pauv mus rau qhov kub siab ua haujlwm. CIVEN METAL tau tsim cov txheej txheem degreasing tob uas tawg los ntawm kev lag luam bottlenecks, muab cov kev daws teeb meem tooj liab siab rau kev tsim khoom siv hluav taws xob siab.

1. Lub Hauv Paus ntawm Cov Txheej Txheem Degreasing: Kev Tshem Tawm Ob Chav ntawm Cov Roj Nto thiab Sab Hauv

1.1 Cov Teeb Meem Roj seem hauv Cov Txheej Txheem Dov

Thaum lub sijhawm tsim cov ntawv ci tooj liab dov, cov hlau tooj liab ingots dhau ntau kauj ruam dov los ua cov ntawv ci. Txhawm rau kom txo qhov kub thiab kev hnav ntawm cov yob, cov roj nplua nyeem (xws li cov roj av thiab cov esters hluavtaws) raug siv ntawm cov yob thiabntawv ci tooj liabnto. Txawm li cas los xij, cov txheej txheem no ua rau cov roj khaws cia los ntawm ob txoj hauv kev tseem ceeb:

• Kev nqus dej ntawm qhov chawNyob rau hauv lub zog dov, ib zaj duab xis roj micron-scale (tuab 0.1-0.5μm) lo rau ntawm qhov chaw ntawm cov ntawv ci tooj liab.
• Kev nkag mus rau sab hauvThaum lub sijhawm dov deformation, lub lattice tooj liab tsim cov qhov tsis zoo me me (xws li dislocations thiab voids), tso cai rau cov roj molecules (C12-C18 hydrocarbon saw) nkag mus rau hauv cov ntawv ci ntawm capillary action, ncav cuag qhov tob ntawm 1-3μm.

1.2 Cov Kev Txwv ntawm Cov Txheej Txheem Ntxuav Ib Txwm Muaj

Cov txheej txheem ntxuav qhov chaw ib txwm muaj (piv txwv li, ntxuav alkaline, so cawv) tsuas yog tshem tawm cov roj ntawm qhov chaw, ua tiav qhov kev tshem tawm ntawm kwv yees li70-85%, tab sis tsis muaj txiaj ntsig tiv thaiv cov roj uas nqus sab hauv. Cov ntaub ntawv sim qhia tau tias yog tsis muaj kev tshem tawm cov roj ntau dhau, cov roj sab hauv rov tshwm sim ntawm qhov chaw tom qab30 feeb ntawm 150 ° C, nrog rau qhov rov qab tso tawm ntawm0.8-1.2g/m², ua rau muaj "kev ua qias tuaj zaum ob."

1.3 Kev Tshawb Fawb Txog Kev Siv Tshuab Hauv Kev Tshem Roj Kom Poob Qis

CIVEN METAL ntiav ib tug"Kev rho tawm tshuaj + kev ua haujlwm ultrasonic"cov txheej txheem sib xyaw ua ke:

1. Kev rho tawm tshuaj lom neegIb tug neeg sawv cev chelating tshwj xeeb (pH 9.5-10.5) rhuav tshem cov roj molecules ntev, tsim cov dej-soluble complexes.
2. Kev pab cuam ultrasonic40kHz high-frequency ultrasound tsim cov teebmeem cavitation, rhuav tshem lub zog khi ntawm cov roj sab hauv thiab lub lattice tooj liab, txhim kho cov roj yaj zoo.
3. Tshuab nqus tsev kom qhuavKev qhuav sai ntawm -0.08MPa qhov siab tsis zoo tiv thaiv kev oxidation.

Cov txheej txheem no txo ​​cov roj seem kom≤5mg/m²(ua tau raws li cov qauv IPC-4562 ntawm ≤15mg/m²), ua tiav> 99% kev tshem tawm zoorau cov roj uas nqus tau sab hauv.

2. Kev Cuam Tshuam Ncaj Qha ntawm Kev Kho Mob Degreasing rau Cov Txheej Txheem Txheej Txheem thiab Thermal Lamination

2.1 Kev Txhim Kho Kev Sib Txuas Hauv Cov Ntawv Thov Txheej

Cov ntaub ntawv txheej (xws li PI adhesives thiab photoresists) yuav tsum tsim cov molecular-level bonds nrogntawv ci tooj liabCov roj seem ua rau muaj cov teeb meem hauv qab no:

• Txo lub zog sib cuam tshuam: Qhov hydrophobicity ntawm cov roj ua rau lub kaum sab xis ntawm cov tshuaj pleev xim nce ntxiv15° txog 45°, cuam tshuam kev ntub dej.
• Kev sib txuas tshuaj lom neeg uas raug txwvCov txheej roj nplaum thaiv cov hydroxyl (-OH) pawg ntawm qhov chaw tooj liab, tiv thaiv kev cuam tshuam nrog cov pawg resin active.

Kev Sib Piv Kev Ua Haujlwm ntawm Degreased vs. Cov Ntawv Nyiaj Tooj Liab:

2.2 Kev Txhim Kho Kev Ntseeg Siab Hauv Kev Siv Thermal Lamination

Thaum lub sijhawm lamination kub siab (180-220 ° C), cov roj seem hauv cov ntawv ci tooj liab ib txwm ua rau muaj ntau qhov tsis ua haujlwm:

• Kev tsim cov npuas: Cov roj uas ua pa tawm tsim10-50μm npuas dej(qhov ceev >50/cm²).
• Kev tawg ntawm cov txheej txheem: Cov roj ua rau cov zog van der Waals ntawm cov epoxy resin thiab cov ntawv ci tooj liab txo qis, ua rau lub zog tev tawv txo qis los ntawm30-40%.
• Kev poob dielectric: Cov roj dawb ua rau muaj kev hloov pauv ntawm dielectric constant (Dk variation >0.2).

Tom qab1000 teev ntawm 85 ° C / 85% RH laus, CIVEN METALNtawv Nyiaj Tooj Liabcov khoom pov thawj:

• Qhov ceev ntawm npuas: <5/cm² (qhov nruab nrab ntawm kev lag luam >30/cm²).
• Lub zog tev tawv: Tswj1.6N/cm2(tus nqi pib1.8N/cm2, tus nqi puas tsuaj tsuas yog 11%).
• Kev ruaj khov ntawm dielectric: Kev hloov pauv ntawm Dk ≤0.05, kev sib ntsibCov kev xav tau ntawm 5G millimeter-wave zaus.

3. Kev Lag Luam thiab CIVEN METAL Qhov Benchmark Position

3.1 Cov Teeb Meem Hauv Kev Lag Luam: Kev Ua Kom Yooj Yim Rau Cov Txheej Txheem Uas Muaj Nqis

Dhau90% ntawm cov tuam txhab tsim cov ntawv ci tooj liabua kom yooj yim rau kev ua cov txheej txheem kom txo cov nqi, ua raws li cov txheej txheem yooj yim:

Dov → Ntxuav Dej (Na₂CO₃ kua) → Ziab → Winding

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

3.2 CIVEN METAL lub "Zero-Defect" Quality Control System

• Kev saib xyuas onlineKev tshuaj xyuas X-ray fluorescence (XRF) rau kev tshawb pom lub sijhawm tiag tiag ntawm cov khoom seem ntawm qhov chaw (S, Cl, thiab lwm yam).
• Kev ntsuam xyuas kev laus sai dua: Ua qauv qhia txog qhov kawg200°C/24 teevcov xwm txheej kom ntseeg tau tias tsis muaj roj rov tshwm sim.
• Kev taug qab tag nrho cov txheej txheemTxhua lub yob muaj ib daim QR code txuas rau32 cov txheej txheem tseem ceeb(piv txwv li, qhov kub thiab txias ntawm kev tshem roj, lub zog ultrasonic).

4. Xaus Lus: Kev Kho Mob Degreasing - Lub Hauv Paus ntawm Kev Tsim Khoom Siv Hluav Taws Xob Zoo Tshaj Plaws

Kev kho cov roj hmab tooj liab uas dov tsis yog tsuas yog kev txhim kho cov txheej txheem xwb tab sis kev hloov kho rau yav tom ntej rau cov ntawv thov yav tom ntej. CIVEN METAL txoj kev siv tshuab tshiab ua rau cov ntawv ci tooj liab huv si mus rau qib atomic, muabkev lees paub txog theem khoom sivraukev sib txuas ceev ceev (HDI), cov voj voog hloov pauv tau ntawm tsheb, thiab lwm yam teb siab kawg.

Nyob rau hauv lubLub caij nyoog 5G thiab AIoT, tsuas yog cov tuam txhab uas paub txogcov thev naus laus zis ntxuav tseem ceebtuaj yeem tsav cov kev tsim kho tshiab yav tom ntej hauv kev lag luam ntawv ci tooj liab hluav taws xob.
