Ruoko rweRobhoti reAlumina Ceramic Rakacheneswa Kwazvo reKubata Wafer
Ruoko rwerobhoti rweSt.Cera rwealumina ceramic rwakagadzirwa nemazvo kubva pa99.8% Al₂O₃ (alumina) yakacheneswa zvakanyanya. Runosanganisa simba reflexural rakasiyana (361 MPa), kuomarara kwakanyanya (16 GPa), uye density yakaderera (3.93 g/cm³), zvichikonzera ruoko rwakareruka asi rwakasimba rwekutamisa wafer ye semiconductor. Kupisa kwekuwedzera kwechinhu (7.2×10⁻⁶/°C) kunoenderana nesilicon zvakanyanya, zvichideredza kusawirirana kwekupisa panguva yekugadzirisa.
Magadzirirwo (zvichibva pa99.8% Al₂O₃):
| Pfuma | Kukosha |
| Ruvara | Nyanga dzenzou |
| Kuwanda kwevanhu | 3.93 g/cm³ |
| Simba reKuchinjika | 361 MPa |
| Kuomarara kwaVickers | 16 GPa |
| Modulus yeYoung | 380 GPa |
| Kufambisa kwekupisa | 32 W/m·k |
| Kuwedzera kwekupisa | 7.2×10⁻⁶/℃ |
| Simba reDielectric | 15×10⁶ V/m |
Mashandisirwo:
- Marobhoti ekutamisa wafer yemuchina wevacuum (200mm/300mm)
- Masisitimu ekubata mhepo
- Maoko ekupedzisira ekugadzirisa otomatiki eFAB
Maitiro Ekugadzira:
Kudzvanya kweIsostatic → green machining → sintering pa1600°C → CNC grinding chaiyo → ultrasonic cleaning → Class 100 cleanroom packaging. Ruoko rumwe nerumwe runoongororwa neCMM 100% kuti ruonekwe kuti rwakati sandara (± 0.01 mm) uye kuti pamusoro paro pakaoma sei (Ra ≤0.4 μm).
Kudzora Hunhu:
St.Cera ine chitupa cheISO 9001:2015. Isu tinoita bvunzo yekupenda dhayi yekutarisa zvidimbu zvidiki, kukotama kwe three-point kwesimba re flexural, uye bvunzo ye dielectric simba zvichienderana neASTM D149.
Zvakanakira pamusoro peSimbi Arms:
- 50% yakareruka kupfuura simbi isina ngura
- Hapana ngura yegalvanic
- Kugadzirwa kwezvikamu zvishoma (≤0.05 zvikamu/cm²)
- Kuvhara kwakachengeteka kweESD kuripo (10⁶–10⁹Ω/sq)
Kugadzirisa:
Hurefu kubva pa150mm kusvika 450mm, maumbirwo emucheto (edge grip, Bernoulli, vacuum), uye mapatani eflange ekumisikidza pamifananidzo yeOEM. Maprototypes mumavhiki maviri.
Kana muchida maodha akawanda, ndapota kumbirai mutengo.
