Khoele ea Sebaka sa Alumina Ceramic e Hlokahalang ka ho Sebetsa bakeng sa Lisebelisoa tsa Semiconductor
Thupa ea sebaka sa letsopa ea St.Cera e siloa ka nepo ho tloha ho 99.8% alumina e hloekileng haholo (Al₂O₃). E fana ka thata e phahameng (16 GPa), khanyetso e ntle ea ho robeha, le botsitso ba litekanyo. Bophara ba mamello bo tiile joalo ka ±0.005 mm, bolelele bo fihlang ho 150 mm. Bokaholimo ba thupa bo hokahane ho Ra ≤0.2 μm bakeng sa ho kenngoa le ho tlosoa ka boreledi. E sebelisoa e le li-alignment pin, li-dowel pin, kapa li-positioning stops ka har'a li-semiconductor process fixtures, li-wafer cassette, le lisebelisoa tsa tlhahlobo.
Litlhaloso (li ipapisitse le 99.8% Al₂O₃):
| Thepa | Boleng |
| Thepa | 99.8% Alumina (Lenaka la tlou) |
| Botenya | 3.93 g/cm³ |
| Matla a ho Tenyetseha | 361 MPa |
| Boima ba Vickers | 16 GPa |
| Modulus ea Young | 380 GPa |
| Bophara ba bophara | 1–20 mm |
| Bolelele ba Nako | 5–150 mm |
Likopo:
- · Lipini tsa ho hokahanya khasete ea wafer
- · Li-bushing tsa li-lift pin direction
- · Lisebelisoa tsa ho fumana li-dowel
- · Liposo tsa ho hokahanya likarete tsa lipatlisiso
Melemo ho feta Tšepe:
- · Ha e na makenete, e hanela mafome
- · Ha ho tlhahiso ea likaroloana ka lebaka la ho tsofala
- · E sireletsang mocheso ka motlakase (>10¹⁴ Ω·mm²/m)
Ho iketsetsa:
Lipheletso tse nang le chamfered, bophara ba mehato, masoba a khoele, kapa liprofaele tsa ntlha tse ikhethileng.
