Passiveisation ndiyo core maitiro mukugadzirwa kwekutendereraCopper foil. Inoita se "molecular-level nhoo" pamusoro, inosimudzira kupokana nekora paunenge uchinyatso kuenderana nemhedzisiro yayo pazvinhu zvinotsoropodza sekudanana uye kuswededzwa. Ichi chinyorwa chinodzika musainzi kuseri kweSpassivation Mechanisms, performance kutengeserana-offs, uye maitiro einjiniya. UchishandisaCiven simbiKuzorora semuenzaniso, isu tichaongorora kukosha kwaro kwakasiyana mukugadzira-kuguma kwemagetsi kugadzira.
1. Passivation: A "molecular-level nhoo" yemhangura foil
1.1 Mashandisiro anoita mafambiro eshanduko
Kuburikidza nemakemikari kana electrochemical kurapwa, compact oxide layer 10-50nm gobvu mafomu pamusoro peCopper foil. Yakaumbwa kunyanya yeCu₂o, Cuo, uye organic complexes, iyi layer inopa:
- Zvipingamupinyi Zvemukati:Iyo oksijeni yakashata coefficients inoderera ku1 × 10 ⁻¹⁴ cm² / s (pasi kubva pa5
- Electrochemical Passivation:Corrosion yazvino density inodonha kubva ku 10μA / cm² kusvika 0,1μA / cm².
- Chemical Inerness:Kumusoro kwemahara simba kwakaderedzwa kubva ku72mj / m² kuenda ku 35mj / m², kudzvanya maitiro anogadzirisa.
1.2 Shanu Key Batsidziro yePassivation

| Yakakwira-tembiricha oxidation (150 ° C) | Maawa maviri (anoshandura dema) | Maawa makumi mana nemasere (anochengetedza ruvara) | + 2300% |
| Hupenyu hwekuchengetedza | 3 mwedzi (vacuum-yakazara) | Mwedzi 18 (yakagadziriswa yakarongedzwa) | + 500% |
| Bata Kudzivisa (mω) | 0.25 | 0.26 (+ 4%) | - |
| Yakakwira-frequency Kuisa kurasikirwa (10GHZ) | 0.15DB / cm | 0.16db / cm (+ 6.7%) | - |
2. Iyo "yakadonhedza pfumo" rePassivation Layers-uye maitiro ekuzvigadzirisa
2.1 Kuongorora Njodzi
- Kuderedzwa kushoma mukuita:Iyo Passivation Layer inowedzera kudzika kweganda (pa 10GHZ) kubva pa1.63μm kusvika 0.72μM
- Kutengesa Matambudziko:Simba rekudzikisa simba rinowedzera mutengesi wenyoro rakanyorova makona kubva ku15 ° kusvika 25 °. Uchishandisa anoshongedza vatengesi pastes (RARY) inogona kukanganisa izvi.
- Dhiziri nyaya:Resin Bondis Simba ringave kudonha
2.2Civen simbi"Kuenzanisa nzira
Gradient Passivation tekinoroji:
- Base layer:Electrochemical kukura kwe 5nm cužo ne (111) yakasarudzika kutarisisa.
- Pakati peLayer:A 2-3nm Benzotrizole (Bta) inozvivhara-inounganidzwa firimu.
- Out layer:Silane Coupling Agent (Aptes) Kuwedzera Resin Desinon.
Optimised Performance mhinduro:
| Metric | IPC-4562 zvinodiwa | Civen simbiCopper foil mhinduro |
| Kumusoro Kuramba (mω / sq) | ≤300 | 220-250 |
| Peel Simba (N / CM) | ≥0.8 | 1.2-1.5 |
| Wemauto Joint Tensile Simba (MPA) | ≥25 | 28-32 |
| Ionic Migration Rate (μg / cm²) | ≤0.5 | 0.2-0.3 |
3. Civen simbi'S Passivation tekinoroji: Regedzera Zvinotarisirwa Nharaunda
3.1 Iyo ina-tier yekudzivirira system
- Ultra-yakatetepa oxide kutonga:Pulse anodization inowana kuringana kusiyana mukati me ± 2nm.
- Organic-Inorganic Hybrid Layers:Bta uye Silane Shanda pamwechete kuti uderedze mari yeCorrosion kusvika 0.003mm / gore.
- Sembe activation kurapwa:Plasma kuchenesa (ar / o₂ gasi musanganiswa) inodzoreredza vaitengesa vanoneta makona kusvika 18 °.
- Chaidzo-nguva yekutarisa:Ellipsometry anovimbisa passivation layer ukobvu mukati me 0.5nm.
3.2 Zvakanyanya Nzvimbo Yenzvimbo Inoshanda
- Humbe highity uye kupisa:Mushure memaawa ane chiuru pa85 ° C / 85% RH, Surponisheni Rishonance inoshanduka ne9%.
- Thermal kuvhunduka:Mushure me200 madhiri e -55 ° C kusvika + 125 ° C, hapana marara anoonekwa muPassivation layer (yakasimbiswa neSEM).
- Kumakemikari kurwisa:Kudzivirira kusvika ku10% HCL vapor inowedzera kubva pamaminitsi mashanu kusvika makumi matatu maminitsi.
3.3 Kuenderana nezvirimo
- 5g millimeter-wave antennas:28GHHZ Kuisa Kuparadza Kurasikirwa kuderedzwa kusvika chete 0.17DB / CM (kuenzaniswa nevanokwikwidza '0.21DB / cm).
- Zvemagetsi emotokari:Passes ISO 16750-4 Munyu Spray bvunzo, ine yakawedzera come kusvika zana.
- IC SUTSTRATY:Adhisheni Simba neABF Resin Runosvika 1.8N / CM (Indasitiri Avhareji: 1.2n / cm).
4. Iyo ramangwana rePassivation tekinoroji
4.1 Atomic layer deposition (Alld) tekinoroji
Kukudziridza Nanolomaminate Passivation Mafirimu anoenderana neAl₂o₃ / tio₂:
- Ukobvu:<5nm, ine basa rekushandira ≤1%.
- Caf (inoitisa anonyatso filation) kuramba:5x kuvandudzwa.
4.2 Kuzvishingisa kupora kwespasivation lager
Kusanganisira microcapsule corrosion inhibitors (benzimidazole derivatives):
- Kuzvishingisa kwekuzvidzora:Kupfuura 90% mukati memaawa makumi maviri nemana mushure mekutsvagira.
- Hupenyu Hushumiri:Yakawedzera kusvika makore makumi maviri (ichienzaniswa nemakore gumi nemashanu emakore 10-15).
Mhedziso:
Passiveisation kurapwa kunowana chiyero chakanatswa pakati pekudzivirira uye kushanda kwekutendereraCopper foil. Kuburikidza nekuziva,Civen simbiAnoderedza kupaza pasi kwespessides, kuchinjisa kuve "nhumbi dzokurwa nadzo" dzinowedzera chigadzirwa chivharo. Sezvo indasitiri yemagetsi inofamba yakakwirira yakakwirira density uye kuvimbika, pfungwa dzakanyatsoitika uye dzinodzorwa dzava dombo redombo remhangura foil kuvaka.
