Ko te tukanga weriweri he tino mahi i enei ra. I te nuinga o te wa ka whakamahia mo te tarai whakarewa. Ko o maatau papa panui noa, raina PCB, panui hiki, tuanui kowiri tira, me etahi atu, he maha nga wa e whakamahi ana i te mahi tarai i roto i a raatau mahi. I te nuinga o te korero, i runga i te ahua o nga mea e taraihia ana, ka taea te wehewehe i te tukanga etching ki nga waahanga e whai ake nei:
Te rere o te tukanga: te whakakoi, te paraihe ranei te horoi i te mata o te pereti parahi → te ta mata me te waituhi photoresistive, te tuhi whakairoiro me te tuhinga → whakamaroke → te whakamaroke i mua i te maimoatanga → te horoi → te kitenga → te tarai → te horoi → te tarai → te horoi → te tango i te paparanga whakamarumaru o te mata → te wai wera horoi → horoi wai matao → muri maimoatanga → hua oti.
Te Rerenga Tukatuka: Te Whakapai i te Mata o te Pereti Ta → Te Taa Mata Te Wai Photoresist Ink → Te whakamaroke → Te Whakaaturanga → Te Whakawhanaketanga → Te Horoi → Te whakamaroke → Te Tirohanga me te Manatoko → Te Whakapakeke Kiriata → Te Waituhi → Te Tangohanga o te Papa Tiaki → Te Horoi.
Te Rere Tukatuka: Te horoi i te mata o te pereti → waituhi waituhi whakaahua mata waituhi → whakamaroke → te whakamaroketanga → te whakawhanaketanga → te horoi → te whakamaroke → te tirotiro me te manatoko → te whakamaroke kiriata → te maimoatanga o te wai kawakore (waituhi karaka) → te whakakore i te waituhi (te horoi waituhi etching photosensitive →) te horoi.
Ahakoa he aha te tukanga weriweri e whakamahia ana mo tetahi mea, ko te mahi tuatahi ko te kowhiri i te waituhi tika. Ko nga whakaritenga whanui mo te kowhiringa o te mangumangu he pai te aukati waikura, te waikawa me te parenga alkali, te waahanga teitei o te waahanga, ka taea te tuhi i nga raina pai, te hohonu o te tarai ki te whakatutuki i nga whakaritenga whakaputa, he tika te utu.
Ko te Waituhi Kahurangi Whakaahua Te Waituhi Kahurangi he waituhi whakairo taumira teitei mo te tuhi mata. Ka taea te whakamahi hei waituhi tarai mo nga papa taiawhio kua taia me te waituhi whakamarumaru mo te kowiri tira me nga papa konumohe. Ka taea e te Hinu Kahurangi Photosensitive te tarai i nga raina pai, te tikanga ki te hohonu o te 20 microns. Hei tango i te mangumangu, ruku noa ki roto i te wairewa konutai konutai 5% wai mo te 60-80 hēkona i te pāmahana wai o 55-60°C. Ka taea te tango tika i te mangumangu.
Ae ra, he nui ake te utu o nga mangumangu whakairo puru whakaahua kawemai i nga waituhi puru noa. Mena kaore i te tino tika nga whakaritenga o te tarai, ka taea e koe te whakamahi i te mangumangu whakamaroke-a-whare, penei i nga tohu panui, kuaha kowiri tira me era atu. Heoi, ki te mea e tika ana kia tika nga hua o te tarai, ka tūtohuhia kia whakamahia he puru puru hopu whakaahua kawemai kia whiwhi ai i te hinu whakairo kounga teitei.
