Intonga yendawo yeCeramic echanekileyo ye-Alumina yezixhobo zeSemiconductor
Intonga yendawo yeseramikhi yaseSt.Cera igutyungelwe ngokuchanekileyo ukusuka kwi-99.8% ye-alumina ecocekileyo (Al₂O₃). Inika ubulukhuni obuphezulu (16 GPa), ukumelana nokuguguleka okugqwesileyo, kunye nozinzo olulinganayo. Ubukhulu bokunyamezela buqinile njenge ±0.005 mm, ubude bufikelela kwi 150 mm. Umphezulu wentonga ujikelezwe kwi Ra ≤0.2 μm ukuze kufakwe kwaye kususwe ngokutyibilikayo. Isetyenziswa njengee-alignment pin, ii-dowel pin, okanye ii-positioning stops kwi-semiconductor process fixtures, ii-wafer cassette, kunye nezixhobo zokuhlola.

Izicelo:
- · Izikhonkwane zokulungelelanisa ikhasethi yewafer
- · Iibhushi zesikhombisi sephini yokuphakamisa
- · Izixhobo zokufumana iidowels
- · Izithuba zokulungelelanisa amakhadi e-probe
Iingenelo ngaphezu kwentsimbi:
- · Ayinamagnethi, ayimelani nokugqwala
- · Akukho kuveliswa kwamasuntswana ngenxa yokuguguleka
- · Ukuthintela ubushushu ngombane (>10¹⁴ Ω·mm²/m)
Ukwenziwa ngokwezifiso:
Iziphelo ezinee-chamfered, ububanzi bezinyathelo, imingxunya enemisonto, okanye iiprofayili zeencam ezenziwe ngokwezifiso.
