Qhov purity ntawm alumina ceramic wafer polished plate disc cuam tshuam li cas rau cov txheej txheem?

Qhov kev dawb huv ntawmalumina ceramic polishing phaj discsmuaj kev cuam tshuam loj heev rau cov txheej txheem, feem ntau yog nyob rau hauv cov cheeb tsam hauv qab no:

1. Cov nyhuv txhuam:

- Cov discs ci ntsa iab alumina wafer uas muaj cov khoom siv siab muab cov nplaim ci ntsa iab zoo dua nrog cov qhov tsis zoo thiab cov khoom tsis huv tsawg dua.

- Kev siv cov khoom siv siab-purity aluminium oxide polishing disc polishing semiconductor wafers tuaj yeem txo qhov chaw tseem ceeb ntawm cov qhov txhab lossis kev ua qias tuaj, txo qhov kev qhia txog cov hlau ions, txhim kho kev siv cov silicon wafers thiab kev ua kom zoo nkauj.

2. Khoom zoo:

- Qhov purity siab ntawm alumina ceramic polished plate discs txhais tau tias lawv cov ntsiab lus impurity tsawg, uas tuaj yeem txo qhov kev ua qias tuaj ntawm qhov chaw wafer los ntawm cov impurities thaum lub sijhawm polishing.

- Cov discs polishing purity siab pab tswj qhov huv ntawm cov khoom, xyuas kom meej tias cov khoom siv semiconductor ua haujlwm ruaj khov thiab ua tau raws li cov txheej txheem nruj.

3. Kev ruaj khov ntawm cov txheej txheem:

- Tus coefficient ntawm thermal expansion ntawm high-purity alumina polishing discs zoo ib yam li silicon, uas pab txo qhov kev ntxhov siab thermal los ntawm kev hloov pauv kub thiab txhim kho kev ruaj khov ntawm cov txheej txheem.

- Cov txheej txheem ruaj khov pab txo qhov tsis zoo hauv cov txheej txheem ntau lawm thiab txhim kho kev ua haujlwm zoo.

4. Kev ruaj khov tshuaj lom neeg:

- Alumina purity siab muaj kev ruaj khov tshuaj lom neeg zoo heev thiab muaj peev xwm tswj nws cov khoom thiab cov qauv hauv ntau qhov chaw tshuaj lom neeg.

- Qhov no ua rau cov discs polishing aluminium oxide uas muaj cov khoom huv si thiab tsis yooj yim rau xeb lossis hnav thaum lub sijhawm ua polishing thiab tswj tau lub neej ua haujlwm ntev dua.

5. Cov txiaj ntsig kev lag luam:

- Txawm hais tias tus nqi pib ntawm lub disc polishing alumina uas muaj purity siab yuav siab, nws cov khoom zoo heev thiab lub neej ua haujlwm ntev txo cov nqi tag nrho ntawm kev tsim khoom.

- Tsis tas li ntawd xwb, cov discs polishing uas muaj purity siab tuaj yeem txhim kho cov khoom zoo thiab cov txheej txheem ruaj khov, txo cov khoom tsis zoo, thiab txhim kho cov txiaj ntsig kev lag luam ntxiv.

6. Kev cuam tshuam ntawm cov cim qhia kev siv tshuab:

- Raws li tsab xov xwm hais txog, cov discs polishing ntawm cov alumina purity siab (99.7% -99.9%) muaj cov khoom zoo heev ntawm lub cev thiab tshuaj lom neeg, xws li lub zog siab, kev tiv thaiv kev hnav siab, kev rwb thaiv hluav taws xob siab, kev ruaj khov tshuaj lom neeg siab, kev tiv thaiv cua sov zoo thiab kev xeb.

- Cov ntsuas kev siv tshuab no cuam tshuam ncaj qha rau qhov cuam tshuam ntawm cov txheej txheem polishing thiab cov khoom zoo.

Alumina ceramic wafer polished plate disc purity muaj qhov cuam tshuam tseem ceeb rau cov txheej txheem, high purity polishing disc tuaj yeem txhim kho cov nyhuv polishing, cov khoom zoo thiab cov txheej txheem ruaj khov, thaum txo cov nqi tsim khoom tag nrho. Yog li ntawd, hauv cov txheej txheem tsim khoom semiconductor, kev xaiv cov high purity alumina polishing discs yog qhov tseem ceeb kom ntseeg tau tias cov khoom zoo thiab txhim kho kev ua haujlwm ntau lawm.
