Kaiwhakaputa Mutunga Ukume Alumina Parakore-Teitei mō ngā Rōpoti Whakahaere Wafer

Ko te pito whakarewa uku alumina a St.Cera he mea hanga tika mai i te 99.8% Al₂O₃ tino parakore mā te whakamahi i ngā taputapu huri CNC 5-tuaka matatau. Kei roto i ā mātou pūkenga hanga ko ngā mīhini huri tika me ngā pokapū miihini CNC, e āhei ai ngā āhua matatini me te tino tika. He angiangi te pito whakarewa (he angiangi ki te 1.5 mm) me te taha mua whakarara mō te whakaurunga wafer maeneene. Ka whakaratohia e te rauemi he pakari teitei (te modulus a Young 380 GPa), he ātete kakahu pai, me te pumau wera tae atu ki te 800°C. Ka hurihia tika ia waeine kia tutuki ai te papatahi o te 0.003mm, te whakarara o te 0.002mm, me te mutunga mata o te Ra0.1, e whakarite ana i te pa o te wafer me te mahi kore-matūriki i roto i ngā taiao FAB semiconductor. Kei te wātea i roto i ngā roa mai i te 150 mm ki te 450 mm, me ngā āhua matamata ritenga (te pupuri taha, Bernoulli, papatahi) me ngā flanges whakairi hei uru ki ngā karetao OEM. Ko ngā kōwhiringa whakaotinga mata ko te paninga kua pania, kua orohia, te paninga whakamarara ESD rānei (10⁶–10⁹ Ω/sq).

Ngā Whakatakotoranga (i runga i te 99.8% Al₂O₃(& ngā āheinga hanga o St.Cera):

Ngā tono:

• · Te whakawhiti anga i roto i ngā karetao korehau me te hau
• · Ngā pānga mutunga aunoa a te FAB mō ngā anga 200mm/300mm
• · Te whakahaere i te angiangi (me te kōwhiringa ESD)

Ngā Āheinga Hanga:
Mā ā mātou mīhini huri tika me ngā pokapū miihini CNC ka taea te whakaputa i ngā wāhanga uku matatini me:

• · Te roa mōrahi o te mīhini: 1500mm
• · Te whānui o waho mōrahi: 600mm
• · Te whānui iti rawa o roto: 0.2mm
• · Te matotoru mōrahi: 100mm

Mana Kounga:
Te tika 0.005mm, te poutū 0.005mm, te porowhita 0.002mm, te whakarara 0.002mm, te āputaputa 0.01mm i manatokohia e te CMM. Ka horoia ia waeine mā te ultrasonic, ā, ka takaihia ki te rūma ma o te Akomanga 100.
