Whanake i roto i Te Ao o te Taura Whakapapa: Nga Motu me Nga Mahi a Roaroa

Te Matatika o ngā Pūtahi Whakapā: Te Whakaaetanga me ngā Momo

Tohu Poutua vs. Tohu Kore-poutua

Ko te whakamahinga o te whakaaetanga o te rauemi tāhū he mea nui i ana whakamahi me ōna ahuatanga, me te kawe i mua atu i ngā rauemi tāhū e noho ai te lead-based solder i roto i tētahi porowhita o tin me lead, i te ratonga 60/40 rānei ko 63/37. Ko tēnā e kuhuna ana i te paepae hāngai iti, me mutu i te wā ka whakaaeke ai te lead-based solder ki te mahi, inā pōurihia ana i roto i ngā āhuatanga whakapono matua. Heoi, me te take o ngā pūtake hauora kino o te arai, kua horahia mai ki runga i ngā tūmomo kore-arai. Ko ngā tūmomo kore-arai, pērā i ngā hāpaitanga o te tin-silver me ngā hāpaitanga o te tin-copper, kua whanake haere i te mana, nā reira ka tirohia ki ngā tikanga taiao, pērā i RoHS, e whakarite ana i ngā mea kino i roto i ngā rīhi me ngā rīhi ā-tau. Ahakoa kei te nui rawa te paepae hāngai o ngā rauemi tāhū kore-arai, kua whakanuia ake tonu rātou hei mea pai taiao.

I raro i te mahi, e rārangi tonu ana ngā kaiwhakapūtake matū ki te matū whati me te pūnaha matua o te whakatōmatua. E ahu ake nei ngā kaiwhakapūtake matū kore i te tūmanako nui me te tūponotanga matua, ā, ka pai hei whakamahinga mō ngā horopaki e hiahiatia ana te whakatūroro. Kāorekaua, e pai rawa atu ana ngā kaiwhakapūtake matū ki te whakatūroro matua, e hēmi ana i ngā wāhanga e hurihuri ana ngā paerewa i ngā huringa wā. Ko te kawe i waenganui i ngā kaiwhakapūtake matū ranei, matū kore ranei, ka hoki mai i ngā take tukuawatea, ko ngā whakarite kotahi hei whakaaturanga i te nui o te āhuatanga taiao, te whakatūroro, me ngā wāhanga noho.

Ngā Rerekētanga i roto i te Pūtau: Rosin vs. Acid

Ko te mōhio i ngā take matua e pā ana i te rosin me te acid core solder he tino hēmama mō te whiriwhiria i te momo e tika ana mō tō kaupapa. Ko te rosin core solder, i hanga mai i ngā hara hara rakau nēnē, kua whakaaroa ki ngā āhuatanga o ngā rorohiko, inā he iti rawa te mate kōrero nei me te waihangatanga noa. I te whakapuaki i ngā pūtahi rorohiko, ka tiakina e te rosin core flux te wherawhera pai o te huringa ā-mahi me te tahutahu i ngā okiokinga i runga i ngā mata, whakapai i te paetanga me te tirotiro o te hononga kua whakapuaki. He kīrehe, he kore whakarere i te waota o te marae whare, e whakamahia ana kia kaua e whakapakari i te āhua o te whatu, he mea hiahia anō ki te whanake i te whaiwhai ranei.

Ngā whakarite, ko te uku ā-rākau kōrero i runga i tētahi flux matua ake e pai ana ki te whanake i ngā mata o ngā mīhini, mea nui ki ngā mahi pūnaha rorohiko, pūnaha here like. Ki te whai ake te mahi matamata nei ka pai hei whakapiki i ngā mata o ngā mīhini matua, pēnei i ngā paipu kopareore, engari ka kitea te whakakaitanga ki te kore ai i nga whakamahinga i utaina, no reira kāore e taea ki te whakamahi mo ngā rorohiko. Ko te taurangi i waenganui i ngā take whakamahi: ko te uku rosin he pai tuatahi mo ngā rorohiko itiiti, me te uku ā-rākau e wātea nei mo ngā whakamahi e hiahiatia ana te whanaketanga o te mata ki te tirotiro i te whakangaro o te hononga.

Ngā Whakamahi Matua Ki Roto I Ngā Taihanga
