I roto i te ao hurihuri tonu o te umanga papa ara iahiko tā (PCB), he mea nui te mahi a te karāhe tino tika nā ōna āhuatanga ahurei e kore ai e hiahiatia mō ngā momo tukanga hanga. I te haere tonu o te ahunga whakamua o te umanga PCB, e akiakihia ana e ngā auahatanga hangarau me te piki haere o ngā tono mō te tino tika me te kounga teitei ake, kua rite te tūranga o te karāhe tino tika kia nui ake te hiranga.
He rongonui te karāhe tino tika mō tōna pumau āhua, tōna pakeke, me tōna ātete ki te kakahu me te whakawhānui wera. Nā ēnei āhuatanga ka waiho hei rauemi pai mō te whakamahi i roto i ngā taputapu hanga PCB, pērā i ngā taputapu miihini tino tika, ngā taputapu ine, me ngā taputapu me ngā taputapu. I te ia o te whakaitiiti me te uaua haere o ngā PCB, kāore anō kia nui ake te hiahia mō te tika ake i roto i ngā tukanga hanga. Ka tutuki i te karāhe tino tika tēnei hiahia mā te whakarato i tētahi turanga pumau me te pono mō te miihini me te ine tino tika.
I te heke mai, i te whanaketanga tonu o te umanga PCB, ka kite tātou i ētahi au e hanga ana i te whakamahinga o te karāhe tino tika. Tuatahi, ko te pikinga ake o te whakamahi i ngā hangarau hanga matatau, pērā i te aunoatanga me te karetao, ka akiaki i te hiahia mō te karāhe tino tika i roto i te whanaketanga o ngā mīhini me ngā taputapu tino tika. He mea nui te karāhe tino tika hei whakarite i te tika me te pono o ēnei pūnaha matatau.
Tuarua, ka pāngia te rapunga me te tukatuka o te kōhatu karāhe tino tika e te ia o te whanaketanga o te oranga tonutanga o te taiao. Me arotahi ngā kaihanga ki ngā mahi keri karāhe tino tika me ngā tikanga tukatuka e pai ana ki te taiao hei whakaiti i te pānga ki te taiao o te tango me te whakamahi i tēnei rauemi whai hua.
Hei tāpiri atu ki tēnā, ko te pikinga ake o te whakamahinga o ngā tohu auau-tiketike me te tere-tiketike i roto i ngā PCB ka hiahiatia te whakawhanake i ngā rauemi me ngā hangarau hou hei whakatika i ngā wero pēnei i te pono o te tohu me te whakahaere wera. Ko te karāhe tino tika, me tōna pumau wera me ōna āhuatanga ārai hiko, tera pea ka whai wāhi nui ki te whakawhanaketanga o ēnei hangarau hou.
Hei whakamutunga, ka noho tonu te karāhe tino tika hei wāhanga nui i roto i te umanga PCB e whanake haere ana. Nā ōna āhuatanga ahurei ka tino hiahiatia hei whakarite i te tino tika me te kounga o ngā tukanga hanga PCB. I te haere tonu o te ahunga whakamua o te umanga, ka kite tātou i te karāhe tino tika e takaro ana i tētahi tūranga nui ki te akiaki i te auahatanga me te whakatutuki i ngā tono e tipu haere tonu ana mō te tino tika me te kounga teitei ake i roto i te hanga PCB.
