Magawo ogwiritsira ntchito zida za granite pazida zopangira ma LCD opanga zinthu

Zida za granite zimagwiritsidwa ntchito kwambiri popanga mapanelo a LCD.Zigawozi zimapereka zinthu zambiri zomwe zimawapangitsa kukhala abwino kuti azigwiritsidwa ntchito pamakina omwe amapanga mapanelo a LCD.Amadziwika ndi kukhazikika kwawo kwakukulu, kusinthasintha kwabwino kwamafuta, komanso kutsika kwamafuta ochepa.Kuphatikizika kwa mawonekedwe awa kumawapangitsa kukhala chinthu chabwino kwambiri pazogwiritsa ntchito zosiyanasiyana monga metrology, kupanga wafer, ndi lithography.

Chimodzi mwazinthu zofunika kwambiri zopangira zida za granite ndikupanga zida za metrology.Zida zimenezi zimagwiritsidwa ntchito poyeza makulidwe a mapanelo, kukhwima kwa malo, ndi kukula kwake.Granite imapereka kukhazikika kwabwino kwambiri, ndipo izi ndizofunikira kwambiri pazida zama metrology chifukwa zimayenera kukhala zokhazikika kuti zipange miyeso yolondola.Izi ndizofunikira kwambiri pakupanga gulu la LCD chifukwa ngakhale kusiyanasiyana pang'ono mu makulidwe kapena kukula kumatha kukhudza momwe chomaliza chimagwirira ntchito.Chifukwa chake, zida za granite zimagwiritsidwa ntchito popanga zida za metrology kuti zitsimikizire zolondola kwambiri komanso zolondola.

Malo enanso opangira zida za granite ndi kupanga makina omwe amagwiritsidwa ntchito popanga zowotcha za silicon.Makinawa ndi ofunikira kwambiri popanga mapanelo a LCD, ndipo ayenera kukhala olondola komanso okhazikika.Granite imapereka kukhazikika bwino komanso kukhazikika, zomwe zimapangitsa kukhala chisankho choyenera pamakina otere.Kuphatikiza apo, zida za granite zimagonjetsedwa kwambiri ndi kugwedezeka, chomwe ndi chinthu china chofunikira kwambiri popanga zowotcha za silicon.

Pakupanga kwa lithography, zigawo za granite zimagwiritsidwa ntchito ngati maziko a matebulo owoneka bwino omwe ndi ofunikira kwambiri pakuchita izi.Matebulo owoneka bwino amayenera kukhala okhazikika kwambiri, ndipo zida za granite zimapereka malowa, zomwe zimathandiza kutsimikizira kulondola pakupanga.Kuphatikiza apo, zida za granite zimagwiritsidwanso ntchito popanga makina a stepper.Makinawa amagwiritsidwa ntchito powonetsa filimu ya photoresist pa zowotcha za silicon pogwiritsa ntchito kuwala koopsa kwa ultraviolet.Kutsika kwamafuta a granite kumapangitsa kukhala chinthu chabwino kwambiri kuti makinawa akhale olondola.

Potsirizira pake, zida za granite zimagwiritsidwa ntchito popanga makina oyendera, omwe ndi ofunikira kuti azindikire zolakwika zilizonse pazitsulo za silicon.Makinawa amagwiritsa ntchito kuwala kwamphamvu kwambiri kuti azindikire zolakwika zilizonse pamawonekedwe a nsalu yopyapyala.Zigawo za granite zimathandiza kuonetsetsa kukhazikika kwa makina oyendera komanso kupewa zolakwika zilizonse pakuwunika.

Pomaliza, madera ogwiritsira ntchito zida za granite pazida zomwe zimagwiritsidwa ntchito popanga mapanelo a LCD ndiambiri komanso osiyanasiyana.Makhalidwe apadera azinthuzi zimapangitsa kuti zikhale zoyenera kugwiritsidwa ntchito mu metrology, kupanga wafer, lithography, ndi makina oyendera.Kugwiritsiridwa ntchito kwa zida za granite m'makinawa kumatsimikizira kuti kupanga ndi kolondola komanso kothandiza, zomwe zimapangitsa kuti pakhale mapepala apamwamba a LCD.Chifukwa chake, opanga akuyenera kupitiliza kugwiritsa ntchito zida za granite pazida zawo kuti asunge mulingo wapamwamba kwambiri pazogulitsa zawo.
