- Whakatauritenga hau wera tono i runga i te mata o te PCB whakarewa tine mata solder me te whakamahana rangi kōpeke whakaōritenga (pupuhi flat) tukanga. Ma te hanga hei paninga whakaahuru waiora ka taea te pai te weldability. Ko te hau wera me te konukura he puhui parahi-sikkim i te hononga, me te matotoru o te 1 ki te 2mil.
- Organic Solderability Preservative (OSP) na roto i te whakatipu matū i te paninga pararopi ki te parahi korekore. Ko tenei kiriata PCB multilayer he kaha ki te whakahē i te waikura, te wera wera, me te makuku ki te tiaki i te mata parahi mai i te waikura (te waikura, te sulfurization ranei, me etahi atu) i raro i nga tikanga noa. I te wa ano, i te pāmahana fehokotakinga o muri mai, ka tere te tango i te rere o te raima.
3. Ni-au matū pani parahi mata ki matotoru, pai ni-au āhuatanga hiko koranu ki te tiaki PCB multilayer poari. Mo te wa roa, kaore i rite ki te OSP, ka whakamahia noa hei paparanga waikura, ka taea te whakamahi mo te wa roa o te PCB me te whiwhi mana pai. I tua atu, kei a ia te manawanui o te taiao kaore i etahi atu tukanga maimoatanga mata.
4. Ko te whakahekenga hiriwa hiko kore i waenga i te OSP me te whakakikorua nickel / koura, he ngawari, he tere hoki te tukanga PCB multilayer.
Ko te whai waahi ki nga taiao wera, makuku me te poke, he pai tonu te mahi hiko me te pai o te weldability, engari ka paheke. Na te mea karekau he nickel i raro i te paparanga hiriwa, karekau he pai katoa te kaha o te hiko o te nickel whakakikorua / ruku koura i te hiriwa kua heke.
5.Ko te kaiwhakahaere i runga i te mata o te PCB multilayer board kua whakakikoruatia ki te koura nickel, tuatahi ki te paparanga nickel me te paparanga koura. Ko te kaupapa matua o te whakakikorua nickel ko te aukati i te whakamaarama i waenga i te koura me te parahi. E rua nga momo koura kua whakakikoruatia ki te nickel: he koura ngawari (koura parakore, ko te tikanga karekau he kanapa) me te koura pakeke (maeneene, pakeke, aukati mau, cobalt me etahi atu mea e marama ake ana te ahua). Ko te koura ngawari te nuinga e whakamahia ana mo te maramara taapi raina koura; Ko te koura pakeke te nuinga e whakamahia ana mo nga hononga hiko kore-paiherea.
6. Hangarau maimoatanga mata whakauru PCB whiriwhiri e rua, neke atu ranei nga tikanga mo te maimoatanga o te mata, nga huarahi noa ko: nickel gold anti-oxidation, nickel whakakikoruai koura precipitation nickel gold, nickel whakakikorua koura rangi wera whakaōritenga, nickel taimaha me te koura rangi wera whakaōritenga. Ahakoa te huringa i roto i te PCB multilayer tukanga maimoatanga mata e kore he nui, me te mea tawhiti-tiki, kia tuhia te reira e te wā roa o te huringa puhoi ka arahi ki te huringa nui. Na te piki haere o te tono mo te whakamarumaru o te taiao, ko te hangarau maimoatanga mata o te PCB ka tino rerekee i nga ra kei mua.
