Passivated Rolled Copper Foil: Gukora Ubuhanzi bwa "Kurinda Ruswa Ingabo" hamwe nuburinganire bwimikorere

Passivation ninzira yibanze mubikorwa byo kuzungurukaumuringa. Ikora nka "ingero ya molekile-urwego" hejuru, ikongera imbaraga zo kurwanya ruswa mugihe iringaniza witonze ingaruka zayo mubintu bikomeye nko gutwara no kugurisha. Iyi ngingo yibanze muri siyanse yuburyo bwimikorere ya passivation, imikorere yubucuruzi, hamwe nubuhanga bwubuhanga. GukoreshaMETAL CIVEN'intambwe nkurugero, tuzasesengura agaciro kayo kihariye murwego rwohejuru rwa elegitoroniki.

1.1 Uburyo Passivation Layeri ikora
Binyuze mu miti cyangwa amashanyarazi, imiti igabanya ubukana bwa 10-50nm hejuru yubuso bwaumuringa. Igizwe ahanini na Cu₂O, CuO, hamwe ninganda kama, iki cyiciro gitanga:

• Inzitizi z'umubiri:Coefficient ya ogisijeni igabanuka kugera kuri 1 × 10⁻¹⁴ cm² / s (munsi ya 5 × 10⁻⁸ cm² / s kumuringa wambaye ubusa).
• Amashanyarazi ya Pasifika:Ubucucike bwa ruswa bugabanuka kuva 10μA / cm² kugeza 0.1μA / cm².
• Ubuvuzi bwa Shimi:Ingufu zubusa zaragabanutse kuva kuri 72mJ / m² kugeza kuri 35mJ / m², bikuraho imyitwarire idahwitse.

1.2 Inyungu eshanu zingenzi za Passivation

2.1 Gusuzuma Ingaruka

• Kugabanuka gahoro mu myitwarire:Igice cya passivation cyongera ubujyakuzimu bwuruhu (kuri 10GHz) kuva kuri 0,66 mm kugeza kuri 0,72 mm, ariko nukugumana umubyimba munsi ya 30nm, kwiyongera birwanya bishobora kugarukira munsi ya 5%.
• Ibibazo byo kugurisha:Ingufu zo hasi zongerera abagurisha kuva kuri 15 ° kugeza kuri 25 °. Gukoresha ibicuruzwa bigurisha (ubwoko bwa RA) birashobora guhagarika iyi ngaruka.
• Ibibazo bya Adhesion:Imbaraga zihuza imbaraga zishobora kugabanuka 10-15%, zishobora kugabanywa muguhuza inzira zikomeye na passivation.

2.2METAL CIVEN'Kuringaniza

Ikoranabuhanga rya Gradient Passivation:

• Urwego shingiro:Gukura amashanyarazi ya 5nm Cu₂O hamwe na (111) icyerekezo cyiza.
• Hagati Hagati:Filime ya 2-33m benzotriazole (BTA) yonyine.
• Igice cyo hanze:Umukozi wo guhuza Silane (APTES) kugirango yongere resin.

Ibisubizo Byakozwe neza:

3. METAL CIVEN'Passivation Technology: Kuvugurura ibipimo byo kurinda

3.1 Sisitemu yo Kurinda Inzego enye

1. Igenzura rya Ultra-Thin Oxide:Pulse anodisation igera kubunini butandukanye ± 2nm.
2. Ibinyabuzima-Ibinyabuzima bitavanze:BTA na silane bakorana kugirango bagabanye igipimo cya ruswa kugeza 0.003mm / mwaka.
3. Kuvura ibikorwa byo hejuru:Isuku ya plasma (Ar / O₂ ivanga gazi) igarura impande zigurisha kuri 18 °.
4. Igenzura-Igihe:Ellipsometrie itanga uburebure bwa passivation muri ± 0.5nm.

3.2 Kwemeza Ibidukikije Bikabije

• Ubushuhe bwinshi n'ubushuhe:Nyuma yamasaha 1.000 kuri 85 ° C / 85% RH, guhangana nubutaka birahinduka munsi ya 3%.
• Ubushyuhe bukabije:Nyuma yinzinguzingo 200 za -55 ° C kugeza + 125 ° C, ntagice kigaragara murwego rwa passivation (byemejwe na SEM).
• Kurwanya imiti:Kurwanya imyuka ya HCl 10% byiyongera kuva muminota 5 kugeza kuminota 30.

3.3 Guhuza Hafi ya Porogaramu

• Antenna ya Millimetero 5G:Igihombo cya 28GHz cyaragabanutse kugera kuri 0.17dB / cm gusa (ugereranije na 0.21dB / cm).
• Ibikoresho bya elegitoroniki:Yatsinze ISO 16750-4 ibizamini byo gutera umunyu, hamwe ninzinguzingo yagutse kugeza 100.
• IC Substrates:Imbaraga zifatika hamwe na ABF resin igera kuri 1.8N / cm (impuzandengo yinganda: 1.2N / cm).

4. Ejo hazaza h'ikoranabuhanga rya Passivation

4.1 Ikoreshwa rya Atomic Layeri (ALD) Ikoranabuhanga
Gutezimbere firime ya nanolaminate ishingiye kuri Al₂O₃ / TiO₂:

• Umubyimba:<5nm, hamwe no kurwanya kwiyongera ≤1%.
• CAF (Imyitwarire ya Anodic Filament) Kurwanya:5x gutera imbere.

4.2 Kwikiza-Passivation Layers
Kwinjizamo microcapsule ruswa inhibitori (ibikomoka kuri benzimidazole):

• Kwikiza wenyine:Kurenga 90% mugihe cyamasaha 24 nyuma yo gushushanya.
• Ubuzima bwa serivisi:Yongerewe imyaka 20 (ugereranije nimyaka 10-15).

Umwanzuro:
Kuvura Passivation bigera ku buringanire bunoze hagati yo kurinda no gukora kugirango bizungurukeumuringa. Binyuze mu guhanga udushya,METAL CIVENkugabanya kugabanuka kwa passivation, kuyihindura "intwaro itagaragara" izamura ibicuruzwa kwizerwa. Mugihe uruganda rwa elegitoroniki rugenda rugana ku bucucike no kwizerwa, passivasi itomoye kandi igenzurwa yabaye urufatiro rwo gukora umuringa.
