Kodi bedi la granite liyenera kusinthidwa nthawi zonse? Kodi nthawi yake yogwirira ntchito ndi yotani?

Bedi la granite ndi gawo lofunika kwambiri m'makina ambiri a semiconductor, lomwe limagwira ntchito ngati malo osalala komanso okhazikika pokonza wafer. Kapangidwe kake kolimba komanso kokhalitsa kamapangitsa kuti likhale lodziwika bwino kwa opanga, koma limafuna kukonzedwa pang'ono kuti likhale labwino.

Choyamba, ndikofunikira kudziwa kuti granite ndi chinthu chachilengedwe chomwe sichimawonongeka. Chili ndi kuchuluka kwakukulu komanso ma porosity ochepa, zomwe zimapangitsa kuti chisawonongeke ndi dzimbiri komanso kusintha. Izi zikutanthauza kuti bedi la granite limatha kukhala kwa zaka zambiri popanda kusinthidwa bola litasamalidwa bwino.

Komabe, ngakhale kuti ndi yolimba, bedi la granite limatha kuwonongeka pakapita nthawi, makamaka ngati lili ndi mankhwala oopsa kapena kutentha kwambiri. Pachifukwa ichi, kuyang'anitsitsa ndi kuyeretsa nthawi zonse ndikofunikira kuti pamwamba pake pakhalebe posalala komanso popanda zolakwika zomwe zingakhudze kukonza kwa wafer.

Ponena za nthawi yogwira ntchito, bedi la granite limatha kukhala zaka zambiri ngati likusamalidwa bwino. Nthawi yeniyeni yogwiritsira ntchito imadalira zinthu zosiyanasiyana, monga mtundu wa granite yomwe imagwiritsidwa ntchito, kuchuluka kwa kuwonongeka kwake, komanso kuchuluka kwa nthawi yosamalira yomwe imalandira.

Kawirikawiri, opanga zida zambiri za semiconductor amalimbikitsa kusintha bedi la granite zaka 5-10 zilizonse kapena zizindikiro za kuwonongeka zikaonekera. Ngakhale izi zingawoneke ngati nthawi zambiri pakusinthidwa, ndikofunikira kuganizira za kulondola kwakukulu komanso kulondola komwe kumafunika pakukonza wafer. Zolakwika zilizonse pamwamba pa granite zitha kubweretsa zolakwika kapena kusagwirizana kwa chinthu chomalizidwa, zomwe zingakhale ndi zotsatirapo zazikulu pazachuma.

Pomaliza, bedi la granite ndi gawo lofunika kwambiri pamakina a semiconductor omwe amatha kukhala kwa zaka zambiri akakonzedwa bwino. Ngakhale kuti lingafunike kusinthidwa zaka 5-10 zilizonse, ndikofunikira kuyika ndalama mu granite yapamwamba kwambiri komanso kukonza nthawi zonse kuti zitsimikizire kuti ntchito yabwino komanso yolondola pakukonza wafer ikuyenda bwino.
