Ingalo Yerobhothi Le-Alumina Ceramic Elihlanzekile Kakhulu Lokuphathwa Kwe-Wafer
Ingalo yerobhothi ye-alumina ceramic kaSt.Cera yenziwe ngokunemba kusuka ku-99.8% i-Al₂O₃ (i-alumina) ehlanzekile kakhulu. Ihlanganisa amandla angavamile okugobeka (361 MPa), ubulukhuni obuphezulu (16 GPa), kanye nobuningi obuphansi (3.93 g/cm³), okuholela engalweni elula kodwa eqinile yokudluliselwa kwe-wafer ye-semiconductor. I-coefficient yokwanda kokushisa kwezinto (7.2×10⁻⁶/°C) ifana ne-silicon eduze, inciphisa ukungalingani kokushisa ngesikhathi sokucubungula.
Imininingwane (kusekelwe ku-99.8% Al₂O₃):
| Impahla | Inani |
| Umbala | Indlovu |
| Ubuningi | 3.93 g/cm³ |
| Amandla Okugobeka | 361 MPa |
| Ukuqina kukaVickers | 16 GPa |
| I-Modulus kaYoung | 380 GPa |
| Ukuqhuba Okushisayo | 32 W/m·k |
| Ukwanda Kokushisa | 7.2×10⁻⁶/℃ |
| Amandla e-Dielectric | 15×10⁶ V/m |
Izicelo:
- Amarobhothi okudlulisa i-vacuum wafer (200mm/300mm)
- Izinhlelo zokuphatha umoya
- Izingalo zomphumela wokugcina zokwenza izinto ngokuzenzakalela kwe-FAB
Inqubo Yokukhiqiza:
Ukucindezela kwe-isostatic → umshini oluhlaza → ukuthungwa kokushisa ku-1600°C → Ukugaya ngokunemba kwe-CNC → ukuhlanza nge-ultrasonic → Ukupakishwa kwegumbi lokuhlanza le-Class 100. Ingalo ngayinye ihlolwa yi-CMM ngo-100% ukuze ithole ukuthi ithambile (± 0.01 mm) kanye nokuqina kwendawo (Ra ≤0.4 μm).
Ikhwalithi yokulawula:
I-St.Cera inesitifiketi se-ISO 9001:2015. Senza ukuhlolwa kokungena kwedayi kwe-micro-cracks, ukugoba kwamaphuzu amathathu kwamandla e-flexural, kanye nokuhlolwa kwamandla e-dielectric ngokwe-ASTM D149.
Izinzuzo ngaphezu kweZingalo Zensimbi:
- 50% ilula kunensimbi engagqwali
- Akukho ukugqwala kwe-galvanic
- Ukukhiqizwa kwezinhlayiya okuphansi (izinhlayiya ezingu-≤0.05/cm²)
- Isembozo esiphephile se-ESD siyatholakala (10⁶–10⁹ Ω/skwele)
Ukwenza ngokwezifiso:
Ubude busukela ku-150mm kuya ku-450mm, izimo ze-tip (i-edge grip, i-Bernoulli, i-vacuum), kanye namaphethini e-flange okufakwayo ngemidwebo ye-OEM. Ama-prototypes emavikini ama-2.
