Kuchotsa Mafuta pa Cholembera cha Mkuwa Chokulungidwa: Njira Yoyambira ndi Chitsimikizo Chofunika Kwambiri pa Kuphimba ndi Kugwira Ntchito kwa Kutentha

Chojambula cha mkuwa chopindidwandi chinthu chofunikira kwambiri mumakampani opanga magetsi, ndipo ukhondo wake wa pamwamba ndi wamkati umatsimikizira mwachindunji kudalirika kwa njira zotsikira pansi monga kuphimba ndi kutentha. Nkhaniyi ikuwunika njira yomwe njira yochotsera mafuta imawongolera magwiridwe antchito a zojambula zamkuwa zokulungidwa kuchokera pakupanga ndi kugwiritsa ntchito. Pogwiritsa ntchito deta yeniyeni, ikuwonetsa kusinthasintha kwake ku zochitika zokonza kutentha kwambiri. CIVEN METAL yapanga njira yapadera yochotsera mafuta yomwe imadutsa m'mipata yamafakitale, kupereka mayankho odalirika kwambiri a zojambula zamkuwa zopangira zamagetsi zapamwamba.

1. Pakati pa Njira Yochotsera Mafuta: Kuchotsa Mafuta Pamwamba ndi Pamkati

1.1 Mavuto Otsalira a Mafuta mu Njira Yozungulira

Pakupanga zojambulazo zamkuwa zopindidwa, zitsulo zamkuwa zimadutsa masitepe angapo opindidwa kuti apange zojambulazo. Kuti achepetse kutentha komwe kumakangana komanso kuwonongeka kwa zozungulira, mafuta odzola (monga mafuta amchere ndi ma esters opangidwa) amagwiritsidwa ntchito pakati pa zozungulirazo ndipepala la mkuwaKomabe, njirayi imapangitsa kuti mafuta asungidwe kudzera m'njira ziwiri zazikulu:

• Kusakaniza pamwamba: Pakukakamizidwa kozungulira, filimu yamafuta ya micron-scale (yokhuthala 0.1-0.5μm) imamatira pamwamba pa pepala la mkuwa.
• Kulowa mkati: Pakayamba kusinthasintha kwa ma circulation, lattice yamkuwa imapanga zolakwika zazing'ono kwambiri (monga kusuntha ndi kutsika kwa ma voids), zomwe zimathandiza kuti mamolekyu amafuta (ma hydrocarbon chains a C12-C18) alowe mu foil kudzera mu capillary action, kufika pa kuya kwa 1-3μm.

1.2 Zoletsa za Njira Zachikhalidwe Zoyeretsera

Njira zoyeretsera pamwamba (monga kutsuka ndi alkaline, kupukuta ndi mowa) kuchotsa mafuta ophikira pamwamba okha, zomwe zimapangitsa kuti pakhale kuchuluka kwa mafuta ophikira pamwamba pa70-85%, koma sizigwira ntchito polimbana ndi mafuta omwe amalowa mkati. Deta yoyesera ikuwonetsa kuti popanda kuchotsa mafuta mozama, mafuta amkati amabwereranso pamwamba pambuyoMphindi 30 pa 150°C, ndi chiŵerengero chobwezeretsanso cha0.8-1.2g/m², zomwe zimayambitsa "kuipitsidwa kwachiwiri."

1.3 Kupita Patsogolo kwa Ukadaulo pa Kuchotsa Mafuta Kwambiri

CIVEN METAL imagwiritsa ntchito"Kuchotsa mankhwala + kuyambitsa kwa akupanga"njira yopangira zinthu zosiyanasiyana:

1. Kuchotsa mankhwala: Chothandizira kuyeretsa mwamakonda (pH 9.5-10.5) chimawola mamolekyu amafuta a unyolo wautali, ndikupanga ma complexes osungunuka m'madzi.
2. Chithandizo cha ultrasound: 40kHz high-frequency ultrasound imapanga zotsatira za cavitation, kuswa mphamvu yomangirira pakati pa mafuta amkati ndi lattice yamkuwa, zomwe zimapangitsa kuti mafuta azitha kusungunuka bwino.
3. Kuumitsa kwa vacuumKutaya madzi mwachangu pa -0.08MPa kupanikizika koipa kumaletsa okosijeni.

Njira imeneyi imachepetsa mafuta otsala ku≤5mg/m²(kukwaniritsa miyezo ya IPC-4562 ya ≤15mg/m²), kukwaniritsa>99% bwino pochotsamafuta olowa mkati.

2. Zotsatira Zachindunji za Kuchotsa Mafuta pa Njira Zophikira ndi Kupaka Mafuta

2.1 Kukulitsa Kumatira mu Kugwiritsa Ntchito Zokutira

Zipangizo zokutira (monga zomatira za PI ndi ma photoresists) ziyenera kupanga ma molecular-level bonds ndipepala la mkuwaMafuta otsala amabweretsa mavuto awa:

• Kuchepa kwa mphamvu yolumikizirana: Kusagwira bwino ntchito kwa mafuta kumawonjezera kukhudzana kwa njira zophikira kuchokera ku15° mpaka 45°, zomwe zimalepheretsa kunyowa.
• Kugwirizana kwa mankhwala koletsedwa: Mafuta otsalawo amatseka magulu a hydroxyl (-OH) pamwamba pa mkuwa, zomwe zimaletsa kuyanjana ndi magulu omwe amagwira ntchito mu resin.

Kuyerekeza Magwiridwe Abwino a Foil Yochotsedwa Mafuta ndi Foil Yambale:

2.2 Kudalirika Kwambiri mu Kutentha kwa Mafuta

Pa kutentha kwambiri (180-220°C), mafuta otsala mu zojambulazo zamkuwa wamba amachititsa kuti zinthu zisamayende bwino:

• Kupanga thovu: Mafuta opangidwa ndi nthunzi amapangaMa thovu a 10-50μm(kuchuluka >50/cm²).
• Kudula pakati pa zigawoMafuta amachepetsa mphamvu za van der Waals pakati pa epoxy resin ndi copper foil, zomwe zimachepetsa mphamvu ya peel chifukwa cha30-40%.
• Kutayika kwa dielectricMafuta omasuka amachititsa kusinthasintha kosalekeza kwa dielectric (kusiyana kwa Dk >0.2).

Pambuyo pakeMaola 1000 a 85°C/85% RH okalamba, CHITSULO CHA CIVENChojambula cha Mkuwaziwonetsero:

• Kuchuluka kwa thovu: <5/cm² (avereji ya mafakitale >30/cm²).
• Mphamvu yochotsa peel: Amasamalira1.6N/cm(mtengo woyambira1.8N/cm, chiŵerengero cha kuwonongeka kwa nthaka ndi 11% yokha.
• Kukhazikika kwa dielectric: Kusintha kwa Dr ≤0.05, msonkhanoZofunikira pa ma frequency a 5G millimeter-wave.

3. Mkhalidwe wa Makampani ndi Udindo wa CIVEN METAL

3.1 Mavuto a Makampani: Kusavuta kwa Njira Zoyendetsedwa ndi Ndalama

Yatha90% ya opanga zojambulazo zamkuwa zokulungidwaKonzani bwino njira yogwirira ntchito kuti muchepetse ndalama, potsatira njira yoyambira yogwirira ntchito:

Kuzungulira → Kusamba m'madzi (Na₂CO₃ yankho) → Kuuma → Kuzungulira

Njirayi imachotsa mafuta pamwamba pa nthaka okha, ndipo kukana kwa mafuta pamwamba pa nthaka pambuyo potsuka kumasintha.± 15%(Njira ya CIVEN METAL imapitilira mkati mwa± 3%).

3.2 Dongosolo Lowongolera Ubwino wa CIVEN METAL la "Zero-Defect"

• Kuwunika pa intaneti: Kusanthula kwa X-ray fluorescence (XRF) kuti mupeze nthawi yeniyeni zinthu zotsalira pamwamba (S, Cl, ndi zina zotero).
• Mayeso ofulumira a ukalamba: Kuyerekeza kwambiri200°C/maola 24zinthu zofunika kuonetsetsa kuti mafuta sadzabweranso.
• Kutsata kwathunthu: Mpukutu uliwonse uli ndi khodi ya QR yolumikizira kuMagawo 32 ofunikira a ndondomeko(monga kutentha kwa mafuta, mphamvu ya ultrasound).

4. Mapeto: Chithandizo cha Kuchotsa Mafuta—Maziko a Kupanga Zamagetsi Zapamwamba

Kuchotsa mafuta m'thupi pogwiritsa ntchito foil yamkuwa yopindidwa sikuti ndi njira yokhayo yosinthira zinthu koma ndi njira yoganizira zamtsogolo yogwiritsira ntchito mtsogolo. Ukadaulo wotsogola wa CIVEN METAL umawonjezera kuyera kwa foil yamkuwa kufika pamlingo wa atomiki, zomwe zimapangitsa kuti zinthu ziyende bwino.chitsimikizo cha zinthuchifukwa chamaulumikizidwe apamwamba kwambiri (HDI), magalimoto osinthasintha, ndi madera ena apamwamba.

MuNthawi ya 5G ndi AIoT, makampani okha ndi omwe amaphunzira bwinoukadaulo woyeretsa wofunikiraakhoza kuyambitsa zatsopano zamtsogolo mumakampani opanga zojambula zamkuwa zamagetsi.
