Ogwe aka robot Alumina seramiiki dị elu maka njikwa Wafer
Ejiri Al₂O₃ dị ọcha nke 99.8% (alumina) mee ogwe aka robot alumina nke St.Cera. Ọ na-ejikọta ike flexural pụrụ iche (361 MPa), ike siri ike dị elu (16 GPa), na obere njupụta (3.93 g/cm³), nke na-eme ka ogwe aka dị fechaa mana sie ike maka mbufe wafer semiconductor. Ihe mejupụtara mgbasawanye okpomọkụ nke ihe ahụ (7.2×10⁻⁶/°C) na-adakọ nke ọma na silicon, na-ebelata enweghị ike na okpomọkụ n'oge nhazi.
Nkọwapụta (dabere na 99.8% Al₂O₃):
| Akụ na ụba | Uru |
| Agba | Ivory |
| Njupụta | 3.93 g/cm³ |
| Ike nke Flexural | 361 MPa |
| Ike Vickers | 16 GPA |
| Modulu nke Young | 380 GPA |
| Ọgbakọ okpomọkụ | 32 W/m·k |
| Mgbasawanye nke okpomọkụ | 7.2 × 10⁻⁶/℃ |
| Ike Dielectric | 15 × 10⁶ V/m |
Ngwa:
- Rọbọt ndị na-ebufe wafer vacuum (200mm/300mm)
- Sistemụ njikwa ikuku
- Ogwe aka ndị na-arụ ọrụ njedebe maka akpaaka FAB
Usoro Mmepụta:
Isostatic pressing → green machining → sintering na 1600°C → CNC comprehensive grinding → ultrasonic Cleaning → Klas 100 Cleanroom packages. CMM na-enyocha ogwe aka ọ bụla 100% maka ịdị larịị (±0.01 mm) na oke elu (Ra ≤0.4 μm).
Njikwa Ogo:
E nyere asambodo na St.Cera ISO 9001:2015. Anyị na-eme nnwale mmiri agba maka obere mgbawa, mgbagọ isi atọ maka ike flexural, na ule ike dielectric dịka ASTM D149 si dị.
Uru karịa ogwe aka ígwè:
- 50% dị mfe karịa ígwè anaghị agba nchara
- Enweghị nchara galvanic
- Mmepụta obere ihe (≤0.05 ihe ndị dị na ya/cm²)
- Mkpuchi nchekwa ESD dị (10⁶–10⁹ Ω/sq)
Nhazi:
Ogologo ya site na 150mm ruo 450mm, ọdịdị isi (njide ọnụ, Bernoulli, vacuum), na ụkpụrụ flange ejikọta dịka eserese OEM si dị. Ụdị ihe atụ n'ime izu abụọ.
Maka iwu buru ibu, biko rịọ maka ọnụahịa.
