Taupae Pūngao Tira Whakamataki

Ko te whetoko ngotu pureke teitei he taputapu hangaia kia tino pono, e āhua ana i tana whakamahinga i ngā ngotu e iti noa ana te pouri, ka tūmanako ai i te kounga tōtika, te tika, me te kounga mata o te mahi whetoko. Ko te puretanga i konei e mōhiotia ana ko ngā paraihe ngotu ake—ko te nuinga ko te rāpoi haurua, te karaiti haurua rānei, te kiriata rānei—e kore ana i ngā kirihou pērā i ngā oksīra metara, ngā kaihui totohu, i ngā waihanga ke atu rānei e āwherengia ai te wear uneven, ngā ngoikera mata, i te tika kāore i te wehe tika. Ko te rāpoi haurua pureke teitei hei tauira, he kounga puretanga 95% neke atu rānei, ke while silicon carbide pureke teitei he iti noa te silikone koretake, te kāpara rānei. Kaua ko ngā paraihe pureke rawa nei he aha, he whakarewa ake, he ōrite ake ki te rahi me te āhua, e āki ai i te wehe tika, te whakahaere i te matū. Ko te kaihui (he nuinga ko te tarukura rite teitei, ko te tarukura rānei) kei te whanaketia kia kore pouri, kia ārai ai i te whakauru ki ngā paraihe me te ārai i te whakarereketanga o te kaihui e kawe ai i ngā kirihou ki te mahi whetoko. Ko te hanganga o te whetoko kei te whakahaerea tino, me te whakaranu o ngā paraihe me te porosity kia tūmanako ai i te mahi whetoko ōrite ki te mata katoa. Ko ngā whetoko ngotu pureke teitei he mea matua ki ngā whakamahinga e hiahiatia ana te tino pono, pērā i te whanaketanga semiconductor (whetoko silikone me gallium arsenide wafers), te whanaketanga waeine whakaahua (te whakatakotoranga lense hurihuri me ngā miri), me te whanaketanga taputapu hauora (te whakamutunga i ngā taumaha miriro). Ki ēnei mara, ko ngā ngoikera mata mikro, ngā pouri rānei e whakakaha ai i te wāhanga korenoho—hei tauira, ko te kotahi te pouri ki roto i te semiconductor wafer e whakautu ai i te oki haupapa katoa. Anō hoki, kei te whakamahia ēnei whetoko ki te ahurea hau ki te whetoko i ngā raupapa turubine me ngā waeine, kei reira te maimoatanga mata me te tika o te rahi e pa ana tika ana ki te kaha o te kora, ki te haumaru anō hoki. Mā te whakaratonga i te whetoko ōrite, korepouri, kei te heke i te roughness mata (ka taea ai te Ra uara iti ake i te 0.02 μm), whakatenatena i ngā tautohetohe (kotahi te nuinga o te ±0.001 mm), me te heke i te hiahia ki te maimoatanga muri i te whetoko. Kei te utu tuatahi teitei engari kei te whakapai ake i te kounga o ngā hua, heke i te tere o te whakakore, me te whakapai ake i te tautohe, nā reira ko ia anō te tuāpapa o te whanaketanga tino pono.
