He maha ngā tukanga i runga i te mata o te tāngia poari ara iahiko : poari PCB tahanga (kahore maimoatanga mata), OSP, Hot Air Whātaumata (tine mata, arahi-free tine), Plating koura, rumaki koura etc. Ko ake kitea enei.
Ko te rerekētanga i waenganui i te koura rumaki me Plating koura
Rumaki koura ko te tikanga o te waipara matū. i hanga te apa matū e te tauhohenga matū piti hāora-whakaiti. Ko te tikanga, ko ngā matotoru te matotoru. Ko te ahua o te tikanga apa waipara nika-koura-koura matū, a taea te whakatutuki i te apa koura matotoru.
Whakamahi whakakikorua Gold te parau tumu o te iahiko, ka karanga ano hoki-hiko. E electroplated hoki te nuinga atu maimoatanga mata whakarewa. 
In the actual product application, 90% of the gold pcb board is the immersed gold pcb board,because the poor solderability of the plated circuit board is his fatal flaw, and it is also the direct cause of many companies to give up the gold plating process!
Whakatakotoria tukanga koura rumaki i runga i te mata o te te papa iahiko tā ki te tae pūmau, wherikotanga pai, whakakikorua maeneene, me solderability pai o te whakakikorua nika koura. Fele e taea te wehea te reira ki wha wāhanga: mua maimoatanga-(tango hinu, moroiti-waikawa, whakahohenga, pou-tuku), nika rerenga, te koura taimaha, pou-maimoatanga (ururua horoi te wai, horoi te wai DI, whakamaroke). Rumaki matotoru koura kei waenganui i 0.025-0.1um.
Tono Gold te ki te maimoatanga mata o te papa iahiko tā no o tona kawe tiketike hiko, ātete pitihāoratanga pai, me te roa roa. Kei te tikanga e whakamahia ana te reira i rite papa matua, maihao PCB papa koura, me ētahi atu te rerekētanga taketake i waenganui i nga papa koura-whakakikoruatia me papa koura-rumakina ko e he pakeke whakakikorua koura. Gold (abrasion ātete) he koura, te koura ngohengohe (kore kakahu ātete). 
1. The crystal structure formed by Immersion Gold and Gold Plating is different. Immersion Gold is much thicker than Gold Plating. Immersion Gold will be golden yellow and yellower than Gold Plating (this is the method of distinguishing between gold plating and heavy gold plating.) a) Gold plating will be slightly white (nickel color).
2. He rerekē te hanganga karaihe i hanga e te koura rumaki me te whakakikorua koura. Ko māmā ki te Weld atu whakakikorua koura rumaki koura, me te kore e meinga fehokotaki'anga kino. Ko tehea ki te mana te ahotea o te poari immerison koura, a ko reira atu hāngai ki te tukanga hononga mō ngā hua herea ia. I te wa ano, kei hoki te koura koura-whakakikoruatia atu i te koura, i te maihao koura koura-fingered he kore te kuhu (hapehape o te pereti koura) atu.
3. He anake nika-koura i runga i te papa i roto i te koura-rumakina poari PCB .Ko tuku tohu i roto i te pānga kiri e kore e pā te tohu i roto i te apa parahi.
Ko atu mätotoru atu te hanganga karaihe whakakikorua koura, e kore e ngāwari ki te whakaputa i hāora 4. rumaki koura.
5. Ki te hiahia te whakanui ake hoki tāngia poari ara iahikotukatuka tika, whanui raina, kua tae mokowā 0.1mm i raro. Ko e pängia ana ki te koura taiawhio poto whakakikorua Gold. Ko te paraharaha koura anake he konukoreko me te koura i runga i te papa, na e kore e mea ohie ki te whakaputa i te iahiko poto koura.
6. Ko te koura rumaki kua anake nika koura i runga i te papa, na te tūhoto pato'ii te i runga i te atu mau herea ia te raina ki te apa parahi. E kore e te kaupapa pā te mokowā ina hanga utu.
7. hoki nga whakaritenga teitei o te poari PCB, he pai ngā whakaritenga flatness, te whakamahi whānui o te koura rumaki , koura rumaki te tikanga e kore e puta i muri i te whakaminenga o te tītohunga moenga mangu. He pai atu i taua o te pereti koura te flatness me mahi ora o te paraharaha koura.
Na I whakamahi reira te nuinga o wheketere te tukanga koura rumaki ki te whakaputa koura poari PCB .Engari, he nui atu te utu atu i te tukanga koura-whakakikorua (atu ihirangi koura) te tukanga koura-rumakina, na reira e tonu he tokomaha nui o ngā hua iti-utu te whakamahi i ngā tukanga koura-whakakikoruatia (pērā i awhi mana mamao, toy papa).
