Poleiti ea Ceramic ea Alumina e Kholo e nang le Sebopeho se Seholo bakeng sa Li-Semiconductor le Li-Fixtures tsa Liindasteri
St.Cera e etsa lipoleiti tsa letsopa tse kholo tse tsoang ho alumina ea 99.8% e hloekileng haholo (Al₂O₃) ka boholo bo phahameng ho fihlela ho 1500mm ka bolelele le bophara ba 600mm. Bokhoni ba rona ba ho sila ka nepo bo fihlella ho ba bataletseng ha 0.003mm ho feta 100mm le ho tšoana ha 0.002mm, ho netefatsa boleng bo tsitsitseng ba bokaholimo bakeng sa lits'ebetso tsa sebaka se seholo. Botenya ho fihlela ho 100mm, qetello ea bokaholimo ho fihlela ho Ra0.1. Lipoleiti tsena li sebetsa e le metheo ea vacuum chuck, li-heater platens, liphanele tsa insulation tsa motlakase, le fatše ea kamore ea ts'ebetso ho semiconductor, ponts'o le tlhahiso ea photovoltaic. Likoti tse phunyeletsang, li-counterbore, le profiling ea bohale lia fumaneha.
