I roto i ngā pūnaha hangarau tino tika, ehara te whiriwhiri rauemi i te whakatau utu engari he tawhā e whakatau ana i te mahi. Ka mahi ngā turanga mīhini, ngā papaaho ine, ngā wāhanga haurua-ira, me ngā hanganga whakahāngai whatu i ngā ātete mai i te maikoromita ki raro ki ngā nanometa. I ēnei tauine, ko te pumau wera, te ōritetanga hanganga moroiti, te whakaiti i te wiri, me te pumau ā-ahu mō te wā roa ka noho hei herenga hangarau nui.

E rua ngā momo rauemi matua e whakamahia whānuitia ana i tēnei mara: ko te karāhe tūturu me ngā uku hangarau matatau (ko te nuinga he rauemi e ahu mai ana i te alumina, i te silicon carbide rānei). Ahakoa e whakamahia ana ngā mea e rua i roto ingā pūnaha tino tika, he rerekē rawa ō rātou takenga ā-tinana, ō rātou hanganga moroiti, me ngā āhuatanga mahi.

Ko ngā pūnaha ahumahi mahi-teitei i whakawhanakehia e ngā kaihanga pēnei i a ZHHIMG e arotake ana i ēnei rauemi ehara hei whakakapi, engari hei otinga mahi motuhake mō ngā hoahoanga pūnaha rerekē.
