Ipleyiti yokuPolisha yeWafer yeAlumina engama-99.7% enomfanekiso oMngxunya

Ipleyiti yokuPolisha yeWafer ye-Alumina engama-99.7% eneHole

Inkcazo emfutshane:

Ipleyiti yokupolisha i-alumina wafer enemingxuma isetyenziswa kwi-semiconductor, petroleum, chemical, photovoltaic, liquid crystal kunye neminye imboni, efana neendawo zoomatshini, iindawo ze-elektroniki, i-microwave induction disk, izixhobo zokufakelwa kwe-insulation kunye nezinye iindawo, izixhobo ze-semiconductor, izixhobo ze-vacuum, izixhobo zokwenza i-liquid crystal kunye nezinye iindawo. Iiceramics ze-alumina ezinkulu kunye nezicocekileyo kakhulu zinexabiso elibalulekileyo kwishishini le-sapphire kunye neshishini le-semiconductor chips. Yinkxaso ephambili kwaye ingasetyenziswa kwi-chemical mechanical polishing (CMP) yee-wafers ze-silicon ze-sapphire kunye ne-semiconductor. Iiceramics ze-alumina ezinkulu kunye nezicocekileyo kakhulu zingasetyenziswa njenge-substrate ye-alumina ye-LCD.

Iinkcukacha zeMveliso

Iimpawu zemveliso

I-alumina ecocekileyo kakhulu, i-99.7% -99.9% ye-alumina.

Amandla aphezulu oomatshini, ukumelana nokuguguleka okuphezulu, ubushushu obuphezulu bombane, uzinzo oluphezulu lweekhemikhali, ukumelana nobushushu obuhle kunye nokumelana nokugqwala. Okwangoku, ukusetyenziswa kwe-ceramic grinding disc semiconductor silicon wafer yeyona ndlela ibalaseleyo nesemgangathweni yokugaya. Inkqubo yokugaya enamacala amabini isetyenziselwa ukugaya i-silicon wafer esikiweyo, kwaye umgangatho we-grinding wafer uphuculwa ngokuphucula inkqubo yokugaya (izinto zediski, ulwelo lokugaya, uxinzelelo lokugaya kunye nesantya sokugaya, njl.njl.). Ngokukodwa, ukusetyenziswa kweepleyiti ze-ceramic endaweni yeepleyiti zesinyithi eziphosiweyo, ukuphepha ukugaya kumphezulu ophambili we-wafer ebangelwa zizilonda okanye ungcoliseko, ukunciphisa ukungeniswa kwee-ion zesinyithi, kunokunciphisa ukucubungula okulandelayo kwe-silicon, kufinyeze ixesha lenkqubo elandelayo (yokugqwala), kuphucule ukusebenza kakuhle kwemveliso, kwaye kunciphise ukulahleka kokucubungula kwe-silicon, kuphucule kakhulu ukusetyenziswa kwe-silicon.

Iinkcukacha zeMveliso

I-Φ850mm, i-45mm okanye ngaphantsi ubukhulu bediski ye-alumina ecocekileyo kakhulu, iringi (ubungakanani bungenziwa ngokwezifiso).
Singakwazi nokuvelisa ezi nkcukacha zilandelayo zeeseramikhi ezikumgangatho ophezulu:
1, 1500x600x25mm ngaphantsi kwebhodi ende, umcu, ibhodi yesikwere, ishiti;
2. Iireli zesikhokelo ezingaphantsi kwe-1000x45x45mm;
3, ubude be-φ300~600x bepayipi engenanto eyi-500mm okanye ngaphantsi, isilinda, ityhubhu ye-vacuum yombane, njl.njl.
4, ungenza ngokwezifiso iintlobo ngeentlobo zeemilo kunye neenkcukacha zeemveliso ze-ceramic ze-alumina ezicocekileyo kakhulu.

Iingenelo zeChemshun Ceramics

Sinamalungelo okuzimela obunikazi bobukrelekrele benkqubo yokubumba ye-PIBM, egxile ekuveliseni izinto zeseramikhi ezintle ezikumgangatho ophezulu. Le nkqubo intsha idlula ekuguqulweni nasekuqhekekeni kwe-billet enkulu yeseramikhi emanzi kwinkqubo yokulungiselela, kwaye ukusebenza kwemveliso kuphuculwe kakhulu xa kuthelekiswa naleyo yeendawo ezinkulu zeseramikhi ezilungiselelwe ngeendlela zemveli.
Idiski yokupolisha ye-alumina ceramic eyenziwe yiPingxiang Chemshun Ceramics Co., Ltd. isebenzisa inkqubo yokubumba ye-PIBM eziziphilisayo. Itekhnoloji ye-PIBM ephucukileyo yamazwe ngamazwe isombulule ngempumelelo ingxaki ephambili yokuguqulwa kwee-crack ze-alumina enkulu enobubanzi. Itekhnoloji ye-PIBM ceramic iya kuvula elinye ifestile elikhanyayo kushishino lwe-ceramic. Asivelisi nje kuphela iipleyiti zokupolisha ze-alumina ceramic ezikumgangatho ophezulu, kodwa sikwabandakanya nezinye ii-ceramics ze-alumina ezinkulu ezicocekileyo, ezifana ne-1200*500*20mm ceramic substrates zezixhobo zokwenza i-LCD, ii-semiconductor transmission rails, izinto ze-vacuum, iindawo zoomatshini ngokubanzi, ii-ceramics ezikhusela iimbumbulu.
