Chithandizo cha Degreasing cha Chojambula Chamkuwa Chokulungidwa: Njira Yachikulu ndi Chitsimikizo Chachikulu cha Kupaka ndi Kutentha Kwambiri Magwiridwe

Anagulung'undisa mkuwa zojambulazondi zinthu pachimake mu makampani amagetsi dera, ndi pamwamba ndi ukhondo mkati mwachindunji kudziwa kudalirika kwa njira kumtunda monga ❖ kuyanika ndi matenthedwe lamination. Nkhaniyi ikuwunikira njira yomwe mankhwala ochotsera mafuta amawongolera magwiridwe antchito a zojambula zamkuwa kuchokera pakupanga komanso kagwiritsidwe ntchito. Pogwiritsa ntchito deta yeniyeni, imasonyeza kusinthasintha kwake ku zochitika za kutentha kwapamwamba. CIVEN METAL yapanga njira yochepetsera yakuya yomwe imadutsa m'mabotolo amakampani, ndikupereka mayankho odalirika azitsulo zamkuwa zopangira zida zapamwamba zamagetsi.

1. Chiyambi cha Njira Yochepetsera: Kuchotsa Pawiri Pamwamba ndi Mafuta Amkati

1.1 Nkhani Zotsalira za Mafuta Pakugudubuza

Pakupanga zojambulazo zopindidwa zamkuwa, ma ingots amkuwa amadutsa masitepe angapo kuti apange zojambulazo. Kuti muchepetse kutentha kwapang'onopang'ono komanso kuvala kwa roll, mafuta opangira mafuta (monga mineral oils ndi synthetic esters) amagwiritsidwa ntchito pakati pa masikono ndizojambula zamkuwapamwamba. Komabe, izi zimapangitsa kuti mafuta asungidwe m'njira ziwiri zazikulu:

• Kutsatsa pamwamba: Pansi pa kugwedezeka, filimu yamafuta a micron-scale (0.1-0.5μm wandiweyani) imamatira pamwamba pazithunzi zamkuwa.
• Kulowa mkati: Panthawi yopukutira, nthiti yamkuwa imapanga zolakwika zazing'ono (monga kusuntha ndi voids), zomwe zimapangitsa kuti ma molekyulu amafuta (C12-C18 hydrocarbon chain) alowe mu zojambulazo kudzera mu capillary action, kufika kuya kwa 1-3μm.

1.2 Zochepera pa Njira Zachikhalidwe Zoyeretsera

Njira zodziwika bwino zoyeretsera pamwamba (mwachitsanzo, kutsuka zamchere, kupukuta mowa) kumachotsa mafilimu amafuta okha, ndikuchotsa pafupifupi pafupifupi70-85%, koma sagwira ntchito polimbana ndi mafuta olowa mkati. Deta yoyesera ikuwonetsa kuti popanda kutsika kwambiri, mafuta amkati amatulukanso pamtunda pambuyo pakeKuphika kwa mphindi 30 pa 150 ° C, ndi mlingo wobwezeretsanso wa0.8-1.2g/m², kuchititsa “kuipitsidwa kwachiwiri.”

1.3 Kupambana Kwaukadaulo Pakuchepetsa Kwakuya

CIVEN METAL amagwiritsa ntchito a"mankhwala m'zigawo + akupanga kutsegula"ndondomeko ya kompositi:

1. Kuchotsa mankhwala: Chizoloŵezi chotchedwa chelating agent (pH 9.5-10.5) chimawola ma molekyulu amafuta amtundu wautali, ndikupanga zovuta zosungunuka m'madzi.
2. Thandizo la Ultrasonic: 40kHz high-frequency ultrasound imapanga cavitation zotsatira, kuswa mphamvu yomangiriza pakati pa mafuta amkati ndi latisi yamkuwa, kupititsa patsogolo kusungunuka kwa mafuta.
3. Kuyanika vacuum: Kutaya madzi m'thupi mwachangu pa -0.08MPa kupsinjika koyipa kumalepheretsa okosijeni.

Njirayi imachepetsa zotsalira zamafuta≤5mg/m²(kukwaniritsa miyezo ya IPC-4562 ya ≤15mg/m²), kukwaniritsa> 99% kuchotsa bwinokwa mafuta olowa mkati.

2. Zotsatira Zachindunji za Chithandizo cha Degreasing pa Kupaka ndi Njira Zopangira Mafuta

2.1 Kupititsa patsogolo Kumata mu Ntchito Zopaka

Zida zokutira (monga zomatira za PI ndi ma photoresists) ziyenera kupanga zomangira zamamolekyulu ndizojambula zamkuwa. Mafuta otsalira amatsogolera kuzinthu zotsatirazi:

• Kuchepetsa mphamvu yapakati: Hydrophobicity ya mafuta imawonjezera njira yolumikizirana ndi mayankho kuchokera15 mpaka 45 °, kulepheretsa kunyowa.
• Kuletsa kugwirizana kwa mankhwala: Kusanjikiza kwamafuta kumatchinga magulu a hydroxyl (-OH) pamtunda wamkuwa, kuletsa zomwe zimachitika ndi magulu a utomoni.

Kufanizitsa Magwiridwe a Degreased vs. Regular Copper Foil:

2.2 Kudalirika Kwambiri mu Thermal Lamination

Pakutentha kwambiri (180-220 ° C), mafuta otsalira muzojambula zamkuwa nthawi zonse amabweretsa zolephera zingapo:

• Kupanga buluu: Mafuta a vaporized amapanga10-50μm thovu(kuchuluka> 50/cm²).
• Interlayer delamination: Mafuta amachepetsa mphamvu za van der Waals pakati pa epoxy resin ndi zojambula zamkuwa, amachepetsa mphamvu ya peel ndi30-40%.
• Kutayika kwa dielectric: Mafuta aulere amachititsa kusinthasintha kosalekeza kwa dielectric (Dk kusiyana> 0.2).

PambuyoMaola 1000 a 85°C/85% RH ukalamba, CIVEN METALChojambula cha Copperziwonetsero:

• Kachulukidwe ka Bubble: <5/cm² (mafakitale avareji>30/cm²).
• Peel mphamvu: Amasamalira1.6N/cm(mtengo woyambira1.8N/cm, chiwopsezo cha 11% yokha.
• Kukhazikika kwa dielectric: Kusintha kwa Dk ≤0.05, msonkhano5G millimeter-wave frequency zofunika.

3. Mkhalidwe Wamakampani ndi Udindo wa CIVEN METAL Benchmark Position

3.1 Zovuta Zamakampani: Kusavuta Kutengera Mtengo

Zatha90% ya opanga zojambulazo zamkuwachepetsani kukonza kuti muchepetse ndalama, potsatira njira yoyambira:

Kupiringa → Sambani madzi (Na₂CO₃ yankho) → Kuyanika → Kupiringa

Njira imeneyi amangochotsa pamwamba mafuta, ndi pambuyo kusamba pamwamba resistivity kusinthasintha wa± 15%(Njira ya CIVEN METAL imakhala mkati±3%).

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

• Kuwunika pa intaneti: Kusanthula kwa X-ray fluorescence (XRF) kuti mudziwe zenizeni zenizeni za zinthu zotsalira pamwamba (S, Cl, etc.).
• Mayeso ofulumira okalamba: Kutengera monyanyira200°C/24hzinthu zowonetsetsa kuti zero mafuta atulukanso.
• Kufufuza kwathunthu: Mpukutu uliwonse umaphatikizapo nambala ya QR yolumikizira32 zofunika ndondomeko magawo(mwachitsanzo, degreasing kutentha, akupanga mphamvu).

4. Kutsiliza: Chithandizo cha Degreasing-Maziko a High-End Electronics Manufacturing

Chithandizo chozama chakuya cha zojambula zamkuwa zokulungidwa sizongowonjezera njira koma kusinthira kuganiza zamtsogolo ku ntchito zamtsogolo. Ukadaulo wopambana wa CIVEN METAL umakulitsa ukhondo wa zojambula zamkuwa mpaka pamlingo wa atomiki, kuperekachitsimikizo chakuthupizahigh-density interconnects (HDI), magalimoto osinthasintha mabwalo, ndi minda ina yapamwamba.

Mu5G ndi AIoT nthawi, makampani okhawo akuchita bwinoukadaulo woyeretsa pachimakeikhoza kuyendetsa zatsopano zamtsogolo mumakampani opanga zojambula zamkuwa.
