Mā te matotoru tika o te whakakikoruatanga ENIG ka ārai i te waikura o ngā papa pango, ka tiakina te pumau o te hononga honohono, ā, ka tautoko i te ātete whakapā iti rawa. Ka tukuna e te nikara i te 3–6 μm he arai horapa pumau mō ngā papa parahi, ā, ka pupuri i ngā ara hiko, ko te koura 0.05–0.15 μm ka ārai i te nikara mai i te waikura tae noa ki te puta o te honohono. Mā ngā rerekētanga i raro i te 3 μm nikara, i te koura 0.05 μm rānei ka nui ake te rahunga whakapā i roto i ngā PCB matotoru, pai-piko.
Te Ine i te Matotoru o te Whakakikorua i roto i te Hanganga PCB
*
Tirohanga Whānui mō te Tukanga Whakakikorua ENIG
Ka tīmata te whakakikoruatanga ENIG mā te whakatakoto i te nikara kore-hiko ki runga i ngā papa parahi, mā te whakamahi i te tauhohenga matū hei hanga i tētahi paparanga nikara-whāwhā kua tohatohahia kia ōrite. Ka pā tika te matotoru o te nikara ki te kaha miihini me te kawe hiko—ko ngā uara i waho o te awhe 2.5–7 μm ka whakanui ake i ngā rahunga huihuinga me te whakaiti i te roa o te oranga o te hua. Ka hipokina te nikara e te taahiraa koura rumaki ki te koura 0.05–0.23 μm mā te nekehanga ionic, ka whakarato i te kapi kore-āputa me te hanganga witi tika. Ko te whakahaere i te ōwehenga nikara-whāwhā ka whakatau i te kounga o te whakaotinga, ko te matotoru koura ōrite ka ārai i te hekenga nikara me te whakaiti i te tūponotanga o te waikura. Ka ine tika te whakamātautau Lonnmeter LONN-T850 XRF i ngā paparanga e rua, ka taea ai te whakahaere kounga whakakikorua PCB pakari me te tutuki i ngā paerewa matotoru whakakikorua ENIG.
Ngā Aratohu Matotoru me ngā Whāinga Kounga mō ENIG
Me noho tonu te matotoru o te whakakikorua nikara mō te ENIG i roto i te 2.5–7 μm kia tutuki ai ngā paerewa IPC-4552B, me te pono teitei rawa atu i waenga i te 3.0–6.0 μm. Mā tēnei whānuitanga nikara ka taea te whakapūmau i te kaha o te whakarewa, he ārai pumau mō te horapa o te parahi, me te ātete waikura whai hua i roto i ngā hoahoa PCB matotoru me ngā hoahoa tuku iho. Me ine te koura rumaki i waenga i te 0.05–0.23 μm, kia pai ake ai te tiaki nikara me te ārai i ngā hononga whakarewa pakarukaru; ko te whānuitanga koura tino noa me te pono ko te 0.05–0.15 μm mō te whakamahinga whakaputa papatipu.
Mā te rerekētanga mai i ēnei paerewa matotoru whakakikorua ka nui ake te tūponotanga o ngā hapa. Ko ngā paparanga nikara i raro iho i te 2.5 μm ka tere te waikura, ka mangu te papa, ka ngoikore hoki ngā hononga whakarewa. Ka taea e te nikara nui te whakararu i te ahotea o roto engari he onge te wāhi pakaru i roto i ngā rohe kua tohua. Mā te koura angiangi ake i te 0.05 μm ka taea te waikura o te nikara, ka whakararu i te roa o te wā me te kaha whakarewa. Ko te koura i runga ake i te 0.23 μm ka hua ake te makuku ngoikore, te whakarewanga nui o te koura, me ngā hononga kāore e pono nā te pakarukaru.
Mā ngā mana whakahaere matotoru tika a te ENIG ka aukati i te hekenga ohorere o te nikara ki te koura, ka mau tonu te ātete pa, ka ārai hoki i ngā pakaru iti-ātete. Mā te hanganga kiko tika i ngā paparanga e rua ka whakarite kia mau te kawe hiko me te mutunga mata ōrite, he mea nui mō te ātete pa iti i ngā wāhi hononga me te BGA. Ka tukuna e ngā tātaritanga Lonnmeter XRF aunoa katoa te ine tika o ngā paparanga nikara me te koura, e tautoko ana i ēnei aratohu kounga tino pakari puta noa i ngā tauine hanga PCB katoa.
Ngā Painga Matua o ENIG mō ngā Papa Ara Iahiko Tānga
Ka tukuna e te ENIG te papatahi tino pai, ka taea ai te whakanoho pai i ngā wāhanga pai-piko me ngā wāhanga matotoru ki runga i ngā papa hiko tā. Ka whakarei ake te koura kikokore i te kaha o te honohono, ka whakatairanga i ngā hononga ōrite me te iti o te hapa. Ka ārai ngā paparanga nikara ōrite i raro i te koura i te waikura me te hekenga, ka whakapakari i te ātete waikura me te tautoko i ngā huringa honohono maha. I roto i ngā rangahau whakahaeretia, ka pai ake te mahi a ngā whakaotinga PCB ENIG i te HASL mā te pupuri i te ātete whakapā iti ake me te whakapai ake i te roa i raro i te haumākū teitei me te ahotea wera. Mō te hanga hiko matatau, ka whakanui ake te whakaotinga ENIG i te pono o te hangarau whakairi mata me te tiaki i te pirau taiao.

Te Whakaurunga Maeneene ki ngā Rerenga Mahi Hanga PCB
Mā ngā āhuatanga pūrongo aunoa ka taea te whai i ia PCB inehia, e hangai ana ki ngā whakaritenga whakahaere kounga i roto i te hoahoa me te hanga papa ara iahiko tā. Ko te atanga ngāwari-whakamahi, i hangaia mō te wā whakangungu iti, ka tere te whakamahi a ngā kaimahi hou me ngā miihini mohio. Ka taea te kaweake i ngā raraunga ine katoa mō te whakahaere tukanga tatauranga me te arotake arotake, ka māmā ake te tutuki i ngā whakaritenga tukanga whakakikorua koura rumaki nikara kore-hiko.
Te Whakarato Hiranga i roto i te Mana Whakatakotoranga ENIG
Ka tutuki te ārai hapa matatau mā te tohu i ngā rerekētanga i mua i te huihuinga, hei tautoko i te whakahaere kounga pai o te whakakikorua PCB. Ka ārai te kaha maha-paparanga o te tātari i te hekenga o te nikara, ā, ka whakarite kia pakari ngā hononga honohono, ka hipa ake i ngā tikanga tuku iho mō te ine i te matotoru o te mata PCB. Ka horapa ngā tauira whakamahinga mai i ngā tono koura rumaki nikara kore-hiko i roto i ngā hikohiko ki ngā whakaotinga PCB ENIG vs. HASL, e whakarato ana i ngā hua paerewa, pono hoki mō te hanga papa ara iahiko tā.
Tonoa he Tāpaetanga mō te LONN-T850 XRF Analyzer
Ka āwhina te tīma ratonga hangarau a Lonnmeter ki ngā tono ritenga me te tautoko tukanga, ka whakatikatika i te whakapainga kounga me te whakarei ake i te hua puta noa i te whakakikorua koura nikara mō ngā papa hiko. Mā te puka tono matihiko ka taea ngā otinga kua whakaritea, ka whakangawari i te tukanga whakatau utu mō ngā miihini me ngā kaihoko.
Ngā Pātai Auau
He aha te ine i te matotoru o te whakakikorua, ā, he aha te mea nui mō te pono o te PCB?
Mā te ine matotoru o te whakakikorua ka ine i ngā paparanga nikara me te koura i runga i ngā mata PCB. Ki te kore e taea te whakapūmau i te matotoru, ka ngoikore te hononga, ka tūpono te waikura o te papa pango, ā, ka tere ake te hekenga o te koura.
He aha ngā matotoru e taunakitia ana mō te whakakikoruatanga ENIG i roto i te hanga PCB?
E tohua ana e ngā aratohu ahumahi te nikara i te 2.5–7 μm me te koura i te 0.05–0.23 μm. Mā ēnei whānuitanga ka whakanui ake i te pono o te hononga honohono, ka ārai i te waikura nikara, ka aukati hoki i te hekenga o te koura me te whakaiti i te whakamahinga koura koretake.
