99.7% Alumina Wafer Polishing Plate ine Hole

Tsananguro pfupi:

Pureti yekupolisha yealumina wafer ine maburi inoshandiswa muma semiconductor, petroleum, chemical, photovoltaic, liquid crystal nedzimwe nzvimbo, dzakadai se mechanical parts, electronic parts, microwave induction disk, insulation materials nezvimwe zvikamu, semiconductor devices, vacuum equipment, liquid crystal manufacturing equipment nezvimwe zvikamu. Saizi hombe uye kuchena kwakanyanya kwealumina ceramics zvine kukosha kwakakosha muindasitiri yesafire neindasitiri yemachipu e semiconductor. Inotsigira zvikuru uye inoshandisika pakupolisha kwemakemikari (CMP) kwemasafire nesilicon wafers e semiconductor. Alumina ceramics yakakura uye kuchena kwakanyanya inogonawo kushandiswa sealumina substrate yeLCD.

Ruzivo rweChigadzirwa

Zvimiro zvechigadzirwa

Alumina yakachena kwazvo, 99.7% -99.9% alumina.

Simba guru remuchina, kuramba kupfeka zvakanyanya, kudzivirira kupisa kwakanyanya, kudzikamisa magetsi zvakanyanya, kugadzikana kwemakemikari kwakanyanya, kuramba kupisa kwakanaka uye kuramba ngura. Parizvino, kushandiswa kwe ceramic grinding disc semiconductor silicon wafer ndiyo nzira yepamusoro uye yemazuva ano yekukuya. Maitiro ekukuya ane mativi maviri anoshandiswa kukuya silicon wafer yakachekwa, uye mhando ye grinding wafer inovandudzwa nekuvandudza maitiro ekukuya (disc material, grinding fluid, grinding pressure uye grinding speed, nezvimwewo). Kunyanya, kushandiswa kwema ceramic plates pachinzvimbo chema cast iron plates, kudzivirira kukuya pamusoro pe wafer inokonzerwa nemavanga kana kusvibiswa, kuderedza kuiswa kwema ions esimbi, kunogona kuderedza kugadziriswa kwe silicon kunotevera, kupfupisa nguva yekushanda (corrosion), kuvandudza kushanda zvakanaka kwekugadzira, uye kuderedza kurasikirwa kwe silicon processing, kuvandudza zvakanyanya kushandiswa kwe silicon.

Zvimiro zveChigadzirwa

Φ850mm, gobvu re 45mm kana pasi pe alumina disc, rin'i (saizi inogona kugadziriswa).
Tinogona zvakare kugadzira zvinotevera zvinotsanangurwa zveceramics dzemhando yepamusoro:
1, 1500x600x25mm pasi pebhodhi refu, mutsetse, bhodhi resikweya, pepa;
2. Njanji dzinotungamira dziri pasi pe1000x45x45mm;
3, φ300~600x kureba kwe500mm isina chinhu, sirinda, chubhu yemagetsi yekuputira, nezvimwewo.

Mabhenefiti eChemshun Ceramics

Tine kodzero dzepfungwa dzakazvimiririra dzePIBM self-curing molding process, tichinyanya kugadzira zvinhu zvemhando yepamusoro zveceramic. Maitiro matsva aya anoputsa magadzirirwo uye kutsemuka kwe ceramic billet yakakura panguva yekugadzirira, uye mashandiro echigadzirwa anovandudzwa zvakanyanya kana tichienzanisa neaya e ceramic hombe dzakagadzirwa nenzira dzechinyakare.
Dhisiki rekupukuta realumina ceramic rakagadzirwa nePingxiang Chemshun Ceramics Co., Ltd. rinoshandisa nzira yePIBM yekuzvigadzirisa. Tekinoroji yepamusoro yepasi rose yePIBM yakagadzirisa dambudziko guru rekushanduka kwealumina dhayamita yakakura. Tekinoroji yePIBM ceramic ichavhura rimwe hwindo rakajeka kune indasitiri yeceramic. Hatingogadziri mapurati ekupukuta ealumina ceramic emhando yepamusoro chete, asiwo tinosanganisira mamwe maerekitironi ealumina ceramics makuru, akadai se1200*500*20mm ceramic substrates dzemidziyo yekugadzira LCD, semiconductor transmission rails, vacuum components, general mechanical parts, bulletproof ceramics.
