E ai ki te maha o nga papahanga PCB, ka wehewehea ki nga papa kotahi-taha, taha-rua, me nga papa-papa-maha.Ko nga tukanga poari e toru kaore i te rite.

Karekau he tukanga paparanga o roto mo nga awhi taha kotahi me te taha-rua, ko te tikanga tapahi-drilling-follow-up.
Ka whai tukanga o roto nga papa paparanga maha

1) Rere tukanga pae kotahi
Te tapahi me te tapatapahi → keri → whakairoiro paparanga o waho → (papa tonu te whakakikorua koura) → te tarai → te tirotiro → te mata hiraka hoto kanohi → (whakariterite rangi wera) → nga tohu mata hiraka → te tukatuka ahua → te whakamatautau → te tirotiro

2) Tukatuka rere o te papa rehu tine taha-rua
Tapatapahi mata huri → keri → te whakapawera parahi nui → paparanga whakairoiro o waho → whakakikorua tine, tango tine tine → keri tuarua → tirotiro → mata whakakikorua kanohi → mono whakakikoruatia koura → whakaōrite rangi wera → tohu mata hiraka → tukatuka ahua → whakamatautau → whakamatautau

3) Te mahi whakakikorua nickel-koura-rua
Tapatapahi oro mata → keri → te whakapawera parahi taimaha → paparanga whakairoiro o waho → whakakikorua nickel, tango koura me te tarai → keri tuarua → tirotirohia → mata hiraka whakakikorua kanohi → tohu mata hiraka → tukatuka ahua → whakamatautau → tirotiro

4) Tukatuka rere o te papa paparanga-maha te papa rehu tine
Te tapahi me te huri → keri rua tuunga → whakairoiro paparanga o roto → paparanga o roto → te tirotiro → te pango → te raima → te keri → te matotoru parahi taimaha → nga whakairoiro paparanga o waho → te whakakikorua tine, te tango tine → te keri tuarua → te tirotiro → te mata hiraka → te koura -puru whakakikorua → Whakatauritenga o te hau wera → Tohu mata hiraka → Tukatuka ahua → Whakamatau → Tirohanga

5) Tukatuka rere o te whakakikorua nickel-koura i runga i nga papa paparanga maha
Te tapahi me te huri → keri kohao tuunga → whakairoiro paparanga o roto → paparanga o roto → te tirotiro → pango → te raima → te keri → te matotoru parahi taimaha → nga whakairoiro paparanga o waho → te whakakikorua koura, te tango kiriata me te tarai → te keri tuarua → te tirotiro → te whakakikorua i te mata → ngā pūāhua tā mata → tukatuka hanga → whakamātautau → tirotiro

6) Tukatuka rere o te pereti paparanga maha rumaki pereti nickel-koura
Te tapahi me te huri → keri kohao tuunga → whakairoiro paparanga o roto → te tarai papa o roto → te tirotiro → te pango → te raima → te keri → te matotoru o te parahi nui → nga whakairoiro paparanga o waho → te whakakikorua tine, te tango tiini → te keri tuarua → te tirotiro → te mata hiraka → te matū Te Koura Rumaki Nickel →Shilk screen characters →Shape processing→Test →Inspection.
