1. Mokotla oa Ts'ebetso ea ho Fokotsa: Ho Tlosoa ha Bobeli ba Bokaholimo le Maqhubu a ka hare

1.1 Mathata a Masala a Oli a Ts'ebetsong

Nakong ea tlhahiso ea foil ea koporo, li-ingots tsa koporo li kena mehatong e mengata ea ho phunya ho etsa thepa ea foil. Ho fokotsa mocheso o sa tsitsang le ho roala ha roll, litlolo (tse kang oli ea diminerale le li-synthetic esters) li sebelisoa pakeng tsa meqolo lefoil ea koporobokahodimo. Leha ho le joalo, mokhoa ona o lebisa ho boloka mafura ka litsela tse peli tsa mantlha:

• Phatlalatso ea bokaholimo: Tlas'a khatello ea ho phalla, filimi ea oli ea micron-scale (0.1-0.5μm e teteaneng) e khomarela holim'a sefahleho sa koporo ea koporo.
• Ho kena ka hare: Nakong ea deformation ea rolling, lattice ea koporo e hlahisa litšitiso tse nyenyane (tse kang li-dislocation le voids), ho lumella limolek'hule tsa mafura (C12-C18 hydrocarbon chain) ho kenella ka foil ka ketso ea capillary, ho fihla botebong ba 1-3μm.

1.2 Meeli ea Mekhoa ea Setso ea ho Hloekisa

Mekhoa e tloaelehileng ea ho hloekisa bokaholimo (mohlala, ho hlatsoa alkaline, ho hlakola joala) ho tlosa lifilimi tsa oli feela, ho fihlela sekhahla sa ho tlosa hoo e ka bang.70-85%, empa ha di na matla kgahlanong le mafura a kenang ka hare. Lintlha tsa liteko li bontša hore ntle le ho fokotseha ho tebileng, mafura a ka hare a hlaha hape ka holim'a metsiMetsotso e 30 ka mocheso oa 150 ° C, ka sekhahla sa botjha deposition ea0.8-1.2g/m², e bakang “tšilafalo ea bobeli.”

1.3 Khatelo-pele ea Theknoloji ka ho Fokotsa ho Tebileng

CIVEN METAL e hira a"Ho ntšoa ha lik'hemik'hale + ts'ebetso ea ultrasonic"mokhoa o kopanetsoeng:

1. Ho ntšoa ha lik'hemik'hale: Setsi sa chelating se tloaelehileng (pH 9.5-10.5) se senya limolek'hule tsa mafura a nako e telele, ho etsa li-complexes tse qhibilihang ka metsing.
2. Thuso ea Ultrasonic: 40kHz high-frequency ultrasound e hlahisa liphello tsa cavitation, ho senya matla a tlamang pakeng tsa mafura a ka hare le lesela la koporo, ho ntlafatsa katleho ea ho qhibiliha ha mafura.
3. Ho omisa ka vacuum: Ho felloa ke metsi ka potlako ho -0.08MPa khatello e mpe e thibela oxidation.

Mokhoa ona o fokotsa masala a mafura ho≤5mg/m²(ho kopana le litekanyetso tsa IPC-4562 tsa ≤15mg/m²), ho fihlela> 99% e sebetsang hantle ea ho tlosabakeng sa mafura a ka hare.

2. Tšusumetso e Otlolohileng ea Kalafo ea ho Fokotsa ka Ho Koaheloa le Mekhoa ea ho Lamination ea Thermal

2.1 Ntlafatso ea ho Adhesion ho Likopo tsa Coating

Lisebelisoa tsa ho roala (joalo ka likhomaretsi tsa PI le li-photoresist) li tlameha ho theha maqhama a molek'hule lefoil ea koporo. Masala a grease a lebisa litabeng tse latelang:

• Fokotsa matla a sefahleho: The hydrophobicity ea grease e eketsa angle ea ho kopana le tharollo ea ho roala ho tloha15 ho isa ho 45 °, ho sitisa ho koloba.
• Khokahano ea lik'hemik'hale e thibetsoeng: Lera la mafura le thibela lihlopha tsa hydroxyl (-OH) holim'a koporo, li thibela ho itšoara ka lihlopha tse sebetsang tsa resin.

Papiso ea Tshebetso ea Degreased vs. Regular Copper Foil:

2.2 Tšepahala e Ntlafetseng ho Thermal Lamination

Nakong ea ho lamination e phahameng ea mocheso (180-220 ° C), mafura a setseng ka foil e tloaelehileng ea koporo e lebisa ho hloleheng hangata:

• Sebopeho sa bubble: Mafura a nang le mouoane a theha10-50μm libubble(bophahamo ba > 50/cm²).
• Interlayer delamination: Grease e fokotsa matla a van der Waals lipakeng tsa epoxy resin le copper foil, e fokotsa matla a lekhapetla ka30-40%.
• Ho lahleheloa ke dielectric: Mafura a mahala a baka ho fetoha ha dielectric kamehla (Dk phapang> 0.2).

KamoraLihora tse 1000 tsa 85°C/85% RH botsofali, CIVEN METALAFoil ea Koporolipontšo:

• Boima ba bubble: <5/cm² (karolelano ea indasteri>30/cm²).
• Matla a peel: E boloka1.6N/cm(boleng ba pele1.8N/cm, sekhahla sa ho senyeha ke 11% feela.
• Dielectric botsitso: Phapang ea Dk ≤0.05, kopanoLitlhoko tsa maqhubu a 5G millimeter-wave.

3. Boemo ba Indasteri le Boemo ba Benchmark ba CIVEN METAL

3.1 Mathata a Indasteri: Ho Nolofatsa Ts'ebetso e Bakiloeng ke Litšenyehelo

Fetile90% ea bahlahisi ba foil ba koporonolofatsa ts'ebetso ho fokotsa litšenyehelo, ho latela ts'ebetso ea mantlha:

Ho roala → Hlatsoa ka Metsi (Na₂CO₃ tharollo) → Ho omisa → Ho Winding

Mokhoa ona o tlosa feela mafura a holim'a metsi, ka mor'a ho hlatsoa sefahleho sa resistivity fluctuations ea±15%(Ts'ebetso ea CIVEN METAL e boloka kahare±3%).

3.2 Sistimi ea Taolo ea Boleng ea CIVEN METAL ea "Zero-Defect".

• Tlhokomelo ea inthaneteng: Tlhahlobo ea X-ray fluorescence (XRF) bakeng sa ho lemoha nako ea sebele ea likarolo tse setseng tsa holim'a metsi (S, Cl, joalo-joalo).
• Liteko tse potlakileng tsa botsofali: Ho etsisa ho feteletseng200°C/24hmaemo a ho etsa bonnete ba hore mafura a zero a hlaha hape.
• Ts'ebetso e felletseng ea ts'ebetso: Moqolo o mong le o mong o kenyelletsa khoutu ea QR e hokahanyang le32 likarolo tsa bohlokoa tsa ts'ebetso(mohlala, mocheso o theohang, matla a ultrasonic).

4. Qetello: Phekolo ea ho Fokotsa-Motheo oa Tlhahiso e Phahameng ea Elektronike

Phekolo e tebileng ea pholiso ea foil ea koporo ha se feela ntlafatso ea ts'ebetso empa ke ho ikamahanya le maikutlo a pele ho likopo tse tlang. Theknoloji ea katleho ea CIVEN METAL e ntlafatsa bohloeki ba foil ea koporo ho isa boemong ba athomo, ho fana katiisetso ya boemo ba thepabakeng salikhokahano tse phahameng tsa density (HDI), likoloi flexible lipotoloho, le masimo a mang a maemo a holimo.
