Ringa Rōpoti Ukume Alumina Parakore-Teitei mō te Whakahaere Wafer
He mea hanga te ringa karetao uku alumina a St.Cera mā te tino tika mai i te 99.8% Al₂O₃ (alumina) tino parakore. Ka whakakotahi i te kaha piko tino pai (361 MPa), te pakeke teitei (16 GPa), me te iti o te mātotoru (3.93 g/cm³), ka hua ake he ringa māmā engari he pakari mō te whakawhiti i te anga haurua-haurua. Ka ōrite te tauwehenga whānui wera o te rauemi (7.2×10⁻⁶/°C) ki te silicon, ka whakaiti i te kore ōritenga wera i te wā tukatuka.
Ngā Whakatakotoranga (i runga i te 99.8% Al₂O₃):
| Taonga | Uara |
| Tae | Āiwi |
| Kiato | 3.93 karamu/cm³ |
| Kaha Whakapiko | 361 MPa |
| Te Pakari o Vickers | 16 GPa |
| Te Tauwehenga o te Rangatahi | 380 GPa |
| Te Arahi Wera | 32 W/m·k |
| Whakawhanuitanga Wera | 7.2×10⁻⁶/℃ |
| Kaha Whakakorehiko | 15×10⁶ V/m |
Ngā tono:
- Ngā karetao whakawhiti anga korehau (200mm/300mm)
- Ngā pūnaha whakahaere hauātea
- Ngā ringa pānga mutunga mō te aunoatanga FAB
Tukanga Hanga:
Te pēhi isostatic → te miihini matomato → te sintering i te 1600°C → te huri tika CNC → te horoi ultrasonic → te takai rūma ma o te akomanga 100. Ka tirotirohia 100% ia ringa e te CMM mō te papatahi (±0.01 mm) me te taratara o te mata (Ra ≤0.4 μm).
Mana Kounga:
Kua whakamanahia a St.Cera e te ISO 9001:2015. Ka whakahaerehia e mātou he whakamātautau werohanga tae mō ngā kapiti moroiti, he piko-ira-toru mō te kaha piko, me te whakamātautau kaha dielectric e ai ki te ASTM D149.
Ngā Painga ki ngā Ringa Whakarewa:
- 50% māmā ake i te maitai kore waikura
- Kāore he waikura konukōre
- Te whakaputanga matūriki iti iho (≤0.05 matūriki/cm²)
- Kei te wātea he paninga haumaru-ESD (10⁶–10⁹ Ω/sq)
Whakaritenga:
Ko ngā roa mai i te 150mm ki te 450mm, ngā āhua o te pito (te pupuri taha, te Bernoulli, te korehau), me ngā tauira whakapiringa e ai ki ngā tuhi a te OEM. Ngā tauira i roto i ngā wiki e rua.
Mō ngā ota nui, tonoa he whakatau utu.
