Ko te pātī tōpuni he wāhinga matua ki te whakaputu i ngā paparorohiko mara autō. Ko te nuinga o ngā pātī tōpuni he pāpaku itiiti, he nekeneke, he mātātā rānei e rere ana tātai ai ki te rāpaki, ā heke kē pea ngā mea atu anō hoki. Ko te mea whakapāwhara i te pātī tōpuni ko te āwhina i ngā wāhinga autō ki te kīato ki te paparorohiko i te wā e hanga ana. Kāore pea ngā taputapu autō anō te pai mēnā kāore i te kounga te pātī tōpuni. Ko te tikanga o te whakamahi i te pātī tōpuni ka taea e ngā kaihanga te whakapiri ki te paparorohiko mā te whakamahi i ngā rōkiroki, ngā putunga rānei. He maha ngā whare wāhanga e whakapono māmā ai te whakamahi i ngā tātātāwha, i ngā tikanga whakaprinti anō hoki nā te kounga o ngā putanga. Ko te tikanga tino pai ake tēnei nā te wā e tāwhai ana i te whakapapa tūturu o ngā wāhinga ki ngā wāhi e tohua ana ki te paparorohiko.
Kei te tū mai te huinga huinga i ngā tahumaero e whai ana kia tūhono ki ngā mahi motuhake, tae atu ki ērā e kore ana i te taraiwa, i te pāmahana iti ake rānei. Ko ngā tauira kore-taraiwa te mea nui ake nei i ēnei rā, no te mea kei te hiahiatia e ngā kamupene kia aru tāwhai ki ngā ture taiao. Ko ēnei huinga e āhua tāone ana i ngā wāhi katoa mai i ngā waea pūhiko, ngā paparorohiko, ngā waka, ā, tae atu ki ngā wāhanga o ngā kaipōkai tuarangi anō hoki. Ko te rerekētanga o ngā kaihanga e whai ana i te rerekētanga o te whāinga me te momo pāmahana e pā ana i te wā o te whakaputa. Ko tēnei mātāturinga tikanga ko te performance pai ake ina whakamahia tika, he mea nui tēnei i te whakaputa i ēnei wā, i reira hoki ka taea e ngā raru iti te whāwhā i ngā raru nui ake i muri mai.
Ko te pātai hiriwa he wehe nui ki te whakapai ake i te mahi tika o ngā hononga hiko. Ina whakamahia tika, ka hangaia e ia ngā hononga kaha e kaha ai te mahi ake o ngā taputapu hiko. Ko te kounga hoki he nui rawa te painga nā te mea ko te pātai hiriwa korekau he take mōrearea. Ko ngā hua korekau e pāngia ana i te wa e hinga ai ngā hononga hiriwa, arānei ka mutu te mahi ake o ngā taputapu i mua i te tautohetohe. Ko ngā rangahau e whakaatu nei ko te nuinga o ngā wā ka pāngia te taputapu ina heke te kounga o te pātai. Ko te aronga ake, ko te nuinga o ngā kaihanga nui ka noho ki ngā tohu whakamana kia kaha ake te utu. I te mutunga, kāore tētahi e hiahia kia hinga kē ā-raraunga no te mea i whakamahi tētahi taputapu iti ake i te wā o te hanga.
Ko te tūhono i te huinga hui tīhei kia tūhono ai katoa te rerekētanga ina hiahia ana kia mau tonu te mahi tika. Ko te nuinga o ngā kaihanga e whakamātau ana kia mau te makariri, e 10 rānei nekeneke Celsius rānei te iti ake, i te wā e whakauru ana i te 40 ki te 60 ōrau te kaha o te wai i te wāhi tūhono. Āwhina ēnei tikanga kia kaua ngā kōpae e tāhuna, e pakaru rānei te wā roa. Ina hē ana ngā mea, ka taea e te nui o te wai i te takotoranga e pani ai te āhua, e whakaputangia ai ngā raru. Ko te kōpae ka tīmata ki te whakakaha, ki te whakakaha rānei, e wāhi nui ai te upoko i ngā wā katoa o ngā mahi hui. Ko te katoa e mōhiotia ana i te kōpae hui kua pakaru kē te mōhio ki te whakapāhunu pea ina hinga ana tētahi tikanga tika ki te pāpaku nā te kore o te tūhono tika.
He nui te whai hua o te tūhono tika i te kauta hui kia mau ai te whai hua o muri mai. Ko te ara pai rawa ko te whakaputu i runga i aua kōpaki taketake i ia wā e āhua taea ana, ā, me whakapōpō katoa rātou. Kei te āwhina te hau ki te whakauru ki reira ka tīmata ki te whakaputaputa i ngā raru marino noa. Kua kitea e tātou katoa te āhua o te kauta hui ina noho tāwhai ana tāwhai - ka huri kia kauta kauta kāore i te taea te mahi tika ake. Ko te whakapōpō tūturu i ngā kōpaki ka tūhono tika ki te aukati i te raru penei. Ko te nuinga o ngā toa e kitea ana ko te arataki iti nei ka aki ai i te moni i te wā roa mai i te aukati i ngā taraiwa kua whakaurua kia pakaru.
Te whakahaere o te wehewehe nui rawa atu hei whakamārama i tētahi huarahi matua. Ka taea e te pūkeke kawe te whakaatu i ngā wehewehe ki ngā wāhi whakatupu, ka rerekē ēnei i tōna māhoratanga, ka whai ake he waehanga ki te whakamahi, ka horomia hoki tōna haurongo. Ki te tiakina pai i roto i ngā wāhanga wehewehe e hāngai ana, ka mau tonu te pūkeke kawe i tōna māhoratanga i hangaia ai, ka taea te mahi pai o ngā mahi kawe.
Ka nui ake ngā mahi pai o te tiakina pai i te pūkeke kawe i runga i te mea ka noho whakamana; ka noho heoi anō hei whakatīnaki i tana wā kai hoki, ka whakapai hoki i tana haurongo. Ko te whakaaro a ngā tohunga ko te mea nei ka rua te wā kai o te pūkeke kawe, ka heke i te rite, ka whai haurongo pai i te hanga o ngā raraunga.
Ka tīmata te nuinga o te hohonu o te paraihe hōhonu ki te tūtohu me te whakahaere tika. I mua i te whakamahi i te paraihe hōhonu, me waiho kia noho ki te tōkau tuarangi i te tuatahi. He nui ake i te nuinga o ngā kaihanga e whakamātau ana kia waihoa i te pō katoa, te iti rawa 8 haora. He aha te take e nui ana tēnei? Ina kāinga te paraihe hōhonu kia māmā, ko tana aratau e toa ana. Kāore te kaha o te kōtai e rereke ana, he mea nui tēnei ina tāpirihia ana ki ngā paparorohiko. Mēnā ka huna tēnei waahanga, ka hua mai ngā raru katoa, mai i te iti o te kaha ki ngā hōhonu paraihe kei te hiahiatia te whakatika anō.
Ina heke te pātai ki te tōaitanga o te rūma, kua wā kia rere tētahi whakarewa pai kia rite te āhua o te katoa. Kātahi ka aukati i ngā kōpiko paku paku ka hua mai, ā, ka tīmata hoki i te wehenga kotahi o ngā mea e mahi ana i runga i te mata. Tangohia he karu ā-ringa, ā, whakarewahia kia māmā noa kia kotahi te meneti, kia rite ai ngā waahanga kua wehe kē. Kaua e whakamahi i te mīhini whakarewa ake – he mīhini ēnei e whakarupeke ai i te aronga o te taraiwa, ā, ka taea hoki e ruin te kounga o te hiriwa i te rite tonu o te mahi.
Ina kāore ngā tāngata e whakahaere i ngā mea tika, ka puta te whakapai tōkeke, ā, ka pā tēnei ki te hōu o ngā kōpiko hōu. He aha te whakatika? Wharia he rāwekenga horoi kia whakamahia anake mō te mahi ki te kōpiko. Kaua e whakapāpaku ki te ringaringa kau. Me whakarite hoki kia horoia ngā kōpaki e mau ana i te kōpiko i ngā wātaka rau. Ko te nuinga o ngā kaiwhakahaere ka whakapuakia e koe kua whakapono ngā tāpiri tino māmā nei ka whai pānga nui. Ko ngā kamupene e whai tikanga ana i ēnei ka kitea e rereke ai te mahi kōpiko hōu, me te roa ake te kore e puta ngā uara pāpaku i muri mai.
Ko te kore e whai whakaaro ki ngā rā whakamutunga o te pāpara hui ka mutunga ki te hua hui iti ake i te tino pai. Ko te rangahau e whakaatu ana kua rere atu te pāpara hui i tana wā tāpuapua, kua ngaro kē tana kaha, e āwhina ai i te iti ake o ngā hononga i waenganui i ngā waahanga me te iti ake o ngā hononga hiko. Ko te arataki a te kaihanga mō te wā e whakakapi ai i te pāpara hui he mea matua mō te katoa e mahi ana ki te huihuinga hiko. Ko ngā urupare o te whakamahi i te pāpara tawhito ka tīmata i ngā raru iti ki te whakamutunga tino o ngā wiri, nō reira ko te tūhono pai me te whai whakaaro ki ngā rā whakamutunga he wāhanga matua o te tikanga hui katoa.
Ko tētahi raru nui kei te pā ana ki te kounga o te pāpara hui ko te hōhonu o te wāhi epuke ana i a rātou. Kei te kitea e mātou tēnei e āhua tūhono ana ina noho ana te pāpara ki ngā wāhi e kaha ana te āwhina i te āhuā. A, ka pēhea i reira? Ka tīmata te wehenga o te taro i te wā e tino tere ake ana, i te wā eke kē pea. Ko te tikanga, he tino whakamātau te whakaputu i te pāpara hui ki te wā katoa. Ko te tāwhai pai rawa ko te noho ki waenganui i te -20 grade Celsius ki te 10 grade Celsius. Mēnā ka tūhono tika ana ki ēnei tikanga, ka roa ake te noho o te pāpara, ā, ka pai tonu ana mahi kia kaua e rerekētia te āhua, te mahi rānei.
Ko te whakamā teitei he āwhina nui kia kaua he whakapōkai katoa i te wā e mōhio ana ki te ra kua mutu te kopa hui me ngā tikanga whakaputu e hiahiatia ana. Me tohu ngā kōpaki kia ma te rā i ahu ai i te rēhihi, me whakarite anō hoki i ngā mea katoa e tau ana. E mōhio ana te nuinga o ngā tāngata he tino pai te aronga First In-First Out mō te whakahaere tāonga. Mā te noho i tēnei tikanga, ka whakamahia ngā kopa tawhito i mua i te kopa hōu e tū ake ana, ka iti ai te māmā. Kua kitea e ngā kamupene kua pakaru te moni mā te whakapau e kaua rawa e wātea ngā rawa kua mutu te wā kia noho ana i te toke kaua ko te whakamahi tūturu.
Ko te whai mōhio e āhua nui ana i te whakahaere i te pāpaku hui he nui te āhua o te whakaiti i ngā hapa, ā, he whai kiko hoki te kounga o ngā hua. Ka piki ake te tino o te huihuinga ina mōhio ngā kaimahi ki te whakahaere, te whakaputu, me te tukatuka i te pāpaku hui. Kua kite kētia e ētahi kaihanga he iti ake ngā whai hapa i muri i te whakauru i ngā wānanga tāpiri. Ko te pāpaku hui he mea he wā tonu atu, ā, he hiahiatia ana ngā tikanga tūmatanui. Mēnā kāore te mōhio, ka mutu pea te whakapilipil i ngā rauemi, te whai hapa rānei ki te hono. Ka whakauru ngā kura anō hoki i te hunga katoa ki ngā tari kia ū tonu ai ki ngā tātai o nāianei, ā, ka aukati hoki i ngā hapa utu nui i te wā o te whakaputa.
Ki te kīhai ake te mōhio ki ngā whakauru me ngā painga o ia taonga, ka nui te whakaheke i te whiriwhiringa o te solder paste tōtika mō ō uara.
Kāore he mātāpuna Sn99Ag0.3Cu0.7 No.4 Pataro Hui Tin e pai ana ki te whakamahi ki ngā papa hiko. Kua hangaia te nuinga mai i te paraihe (kei te tata ki te 99%), tāpirihia atu ko te iti noa o te hiriwa i te 0.3% me te paraihe i te 0.7%, tēnei aronga e āwhina ana i te waiu o te wera me te kaha ki te whakawhitinga i te hiko. He pai ake te kāore he mātāpuna ki te taiao, nō reira e āwhina ana i ngā whare hanga hiko i ngā mahi tino whai tikanga ina hiahiatia ngā hui tika. He tino kaha tēnei hui ki ngā wā kia tūhono tūturu i te wā roa, ā, he āhua nui, ki ngā umanga pērā i te rere ā-hau me ngā taputapu hauora i reira kāore he wāhi mō te rahurahu. Anō hoki, ka āki ai ngā kaihanga e mōhio ana kei te tōtika ō rātou tikanga ki ngā tikanga taiao o nāianei me ngā whāinga whakapūāwaitanga.
Ina hōuia ana ki ngā mahi huihuinga kātai ake, kei te mātua whakamahi tonu ngā tēhina rākau Sn63Pb37. Kei te pai tana mahi mō ngā hiahia SMT ina he tino pai te taraiwa o te 63% tēhina me te 37% mātā. Ko te mea e rite ai ko te iti noa o ngā taunga i muri i te whakamahinga, nō reira kāore he hiahia ki te whakamātau i muri i te huihuinga ka whakaorangia i te wā ki ngā ratonga huihuinga. Kei te nuinga o ngā toa whakatika hiko me ngā whare huihuinga e mōhio ana ngā kaimahi ki te whakamahi i tēnei kirihi ina mōhio ana ki te āhua o te hua. Kei te rere tino pai te kirihi ki te takotoranga taketake i te wā o te whakamahinga, ā, he hononga pakari ka hangaia e ai ki te hiko tūturu kore he raru i muri mai.
Ina mahi ana me ngā hiahia hāngai ki te pāpaku, ko te Parurenga Tin Tinga Kaiwhakakaha Pāpaku Sn60Pb40 te kōwhiringa pai. Kua hangaia mai i te 60% tineke me te 40% kaiwhakakaha, kei te pai tana mahi me te iti ake i te mōrahi o te wera, ā, kei te pakari tonu hoki te hononga me te whakauru pai. Ko te pono tino nui ko te awhina i ngā wāhi iti nei, ngā wāhi e kore e taea te nui ake o te wera. Ko te whakamahi i tēnei parurenga ka awhina i te nui ake o te wera e whakapokapu ai i ngā wāhanga utu nui i te wā o te whakaputanga.
Kei te pai te Sn55pb45 Tin Lead Solder Paste mō ngā papa PCB LED me ngā whakauru rāwhiti anō hoki. Ko te takotoranga ko te 55 ōrau tinnara kua rēwahia ki te 45 ōrau taramea, kei te pakari tēnei mea ina hāngai ana ki ngā hononga hiko pūmau e hiahiatia ana kia pai ai te mahi a ngā waahanga LED. He aha te mea e wehe ai i tēnei pāpā hiko? Kei te pai tana mahi tahi ki ētahi atu ngota e wātea ana i te wā penei. Ko ngā kaihangarau e mahi ana i ngā pūmahara whakamārama ka kitea e rātou ka taea e ratou te whakarereke i te mahi mai i te kaupapa ki te kaupapa, he iti noa te rahi o ngā rama raro papa rānei, he nui rānei te tāpa whakamārama hokohoko. Koia nei te take i nui atu ai te maha o ngā kaiwhakamahi pakihi ki te hoki mai ki tēnei hua tūmatanui ake i te maha o ngā kōwhiringa kei te wā tonu.
Nō reira, kei ēnei mahi, he uru ora nui ngā painga e whakarite ana ki ngā hiahia īwangi, āhei ana te hunga toitū i roto i te whenua ki ō rātau whakapuaki taurangi me te whaihua nui i roto i ngā mahi tāpuhi.
