Pasivation ni inzira yibanze mumusaruro wa roddUmuringa. Ikora nkingabo rusange-urwego "hejuru, yongerera imbaraga kugaburira mugihe aringaniza neza ingaruka zayo kubibazo bikomeye nkiying neza. Iyi ngingo isize muri siyanse inyuma yuburyo bwo kwitondekanya, ibicuruzwa bikora ibikorwa, hamwe nubushakashatsi. GukoreshaCiven'Breamthroges nkurugero, tuzasesengura agaciro kayo gasanzwe mumikorere ya elegitoroniki yo hejuru.
1. Passivetion: "Ingabo-ya Molekuline-Urwego" kumuringa
1.1 Ukuntu impapuro z'igihugu
Binyuze mu kuvura imiti cyangwa kuri electrochemical, ahantu nyaburanga oxide igice cya 10-50nm cyimbitse hejuru yaUmuringa. Yahimbwe cyane cyane ya cu₂o, cuo, nibigoye kama, iyi shusho itanga:
- Inzitizi z'umubiri:Gutunganya ogisijeni kugabanuka kuri 1 × 10⁻¹⁴ cm² / s (hasi kuva 5 × 10⁻⁸ cm² / s kumarira yambaye ubusa).
- Iburafu rya electrochemical:BORROSONION FORTY HOSPITIKI YUZUYE ZA 10μI / CM² kugeza 0.1μsa / CM².
- Impeta yimiti:Ubuso bwubuntu bugabanuka guhera 72mj / m² kugeza 35mj / m², guhagarika imyitwarire igenda yinjira.
1.2 Inyungu eshanu zingenzi zo gutangwa
| Imikorere | Umuringa utavuwe | Pasiporo yumuringa | Gutezimbere |
| Ikizamini cyumunyu (amasaha) | 24 (ibimenyetso bigaragara) | 500 (nta ruswa igaragara) | + 1983% |
| Okiside ndende (150 ° C) | Amasaha 2 (ahinduka umwirabura) | Amasaha 48 (akomeza ibara) | + 2300% |
| Ubuzima bwo kubika | Amezi 3 (yuzuye-yuzuye) | Amezi 18 (bisanzwe bipakiye) | + 500% |
| Menyesha Kurwanya (Mω) | 0.25 | 0.26 (+ 4%) | - |
| Gutakaza cyane kwinjiza (10GHZ) | 0.15DB / CM | 0.16DB / CM (+ 6.7%) | - |
2. "Inkota-ebyiri" yo muri pasiviziyo-nuburyo bwo kuringaniza
2.1 gusuzuma ingaruka
- Kugabanuka gato mubikorwa:Igice cy'ibihugu byongera ubujyakuzimu bw'uruhu (kuri 10GHZ) kuva kuri 0.66μm kugera kuri 0.72μm, ariko ukomeza kubyimba munsi ya 30nm, ikiruhuko cyiyongera gishobora kugarukira ku 5%.
- Ibibazo byo kugurisha:Ingufu zo hejuru ziyongera inguni zitose kuva 15 ° kugeza kuri 25 °. Ukoresheje urupapuro rwibikorwa (ubwoko) burashobora guhagarika izo ngaruka.
- Ibibazo by'imyidagaduro:Imbaraga zo guhuza imbaraga zirashobora guta 10-15%, ishobora guhungabana muguhuza inzira zifatika kandi zitondekanya.
2.2Civen'Kuringaniza Uburyo
Ikoranabuhanga rya Gradiventient Pationory:
- Urwego rushingiye.Iterambere rya electrochemical ya 5nm cu₂o hamwe na (111) icyerekezo cyatoranijwe.
- Hagati Hagati:A 2-3NM BENZERETRIE (BTA) firime yo kwiteranya.
- Igice cyo hanze:Umukozi wa Silane (aptes) kugirango ashyireho ibihisho.
Ibisubizo byimikorere bya Optimined:
| Metric | IPC-4562 Ibisabwa | CivenINGINGO ZIKURIKIRA |
| Kurwanya hejuru (Mω / SQ) | ≤300 | 220-250 |
| Imbaraga za Peel (n / cm) | ≥0.8 | 1.2-1.5 |
| Abacuruzi hamwe nimbaraga za tensile (MPA) | ≥25 | 28-32 |
| Igipimo cyo kwimuka cya Ionic (μg / cm²) | ≤0.5 | 0.2-0.3 |
3. CivenIkoranabuhanga ryo kwishyiriraho: Gutanga ibipimo byo kurinda
3.1 Sisitemu yo Kuringaniza Ibice bine
- Kugenzura ultra-yorohejePulse Anodisation igera kuburinganire muri ± 2nm.
- Ibice bya Organic-idasanzwe:Bta na Silane bakorera hamwe kugirango bagabanye igipimo cya 0,003mm / umwaka.
- Gutunganya ubuso:Gusukura (Ar / o₂ kuvanga gazi) bigarura inguni itose inguni kugeza kuri 18 °.
- Gukurikirana igihe nyacyo:Ellipimetry iremeza igice cyimigenzo ya pasiporo muri ± 0.5nm.
3.2 Ibidukikije Bikabije Kwemeza
- Ubushuhe bukabije n'ubushyuhe:Nyuma yamasaha 1.000 saa 85 ° C / 85% rh, kurwanya hejuru ihinduka munsi ya 3%.
- Ubushyuhe:Nyuma yingano 200 ya -55 ° C kugeza + 125 ° C, nta bice bigaragara mumwanya wigihugu (byemejwe na Sem).
- Kurwanya imiti:Kurwanya 10% VCL VCL yiyongera kuva muminota 5 kugeza kuminota 30.
3.3 Guhuza hirya no hino
- 5g Milimetero-Wave Antennas:28GHZ yometseho igihombo cyagabanutse kuri 0.17DB / cm (ugereranije nabanywanyi '0.21db / cm).
- Ibikoresho bya elegitoroniki:Passs ISO 16750-4 Spray Spray Ibizamini, hamwe nizunguruka kuzunguruka kugeza 100.
- Indangagaciro:Imbaraga zo gupfusha hamwe na Abf Rein igera kuri 1.8n / CM (impuzandengo yinganda: 1.2n / cm).
4. Kazoza k'ikoranabuhanga
4.1 Gushiraho Ikoranabuhanga (ALD)
Gutezimbere firime za Nanolamination zishingiye kuri Al₂o₃ / Tio₂:
- Ubunini:<5nm, hamwe no kurwanya uburwayi bwiyongera ≤1%.
- CAF (filasic ya anodic ya anodic)) Kurwanya:5X.
4.2 Ibice byo kwihatire
Gushiramo MicroCapsule ibirabunge (BenziMidazole Bikomokaho):
- Gukora neza:Hejuru ya 90% mugihe cyamasaha 24 nyuma yo gushushanya.
- Ubuzima bwa serivisi:Yagutse kugeza kumyaka 20 (ugereranije nimyaka 10-15).
Umwanzuro:
Ubuvuzi bwihariye bugera kuringaniza neza hagati yo kurinda no gukora kuzungurukaUmuringa. Binyuze mu guhanga udushya,CivenMugabanye ibibi byihariye, bihindura intwaro "zitagaragara" zizamura ibicuruzwa byifuzo. Nkuko inganda za elegitoroniki zigenda zigana mubucucike bwinshi no kwizerwa, neza kandi bigenzurwa inshuro zigenzurwa byahindutse imfuruka yumuringa wumuringa ukora.
