Ngā momo me te kōwhiringa o te waea whakairo

He tino hira te mahi o te whakairi i ngā wāhanga i roto i ngā āpure rerekē, otirā i roto i te hiko me te putorino. Te kōwhiri i te momo tika o te tāwai he mea nui ki te whakatutuki i ngā hononga roa, kounga teitei. I tēnei rā, ka tirotirohia e mātou ngā momo waea whakairo e wātea ana, ngā āhuatanga hei whakaaro i te wa e whiriwhiri ana i tētahi, me ngā tikanga pai hei whakarite kia angitu te whakairo.

Te Māramatanga o te Waea Whakapā

He aha te Tāwai Whakapiri?

Ko te waea solder he konumohe whakarewa whakarewa, he tikanga kei roto te tine me te mata, he rereke ranei kaore he mata, e whakamahia ana hei hanga hononga kaha i waenga i nga waahanga whakarewa. Ka wera ana, ka rewa te waea whakapiri, ka rere ki roto i nga hononga, ka whakapakeke i te makariri ki te hanga hononga pono.

Ngā Whakamahi o te Niho Poraka

He nui te waea solder i roto i ngā tono maha, tae atu ki:

• Hikohiko : Ka whakamahia whānuitia hei whakakotahi i ngā papa ara iahiko tā (PCBs), hei whakairi i ngā hononga hiko, hei whakatika i ngā pūrere.
• Te mahi putorino : Ka honoa ngā putorino whakarewa me ngā taputapu, ka whakarato i ngā hiri-kore-whakaheke.
• Te Hanga Kī : Whakamahia hei whakapiri i ngā wāhanga whakarewa i roto i ngā hoahoa matatini.

Ngā momo waea whakairo

He whakarewa raima

Ko te konumohe konumohe he huinga konumohe me te raima, e whakamahia nuitia ana i roto i te hikohiko na te mea he pai te whakamakuku me te iti o te rewa (ko te tikanga e 183-190 °C). Ahakoa he pai ake te mahi a te solder, kua iti ake te rongonui na te hauora me nga awangawanga taiao e pa ana ki te whakaputanga o te mata.

He whakarewa kore-waro

I te piki haere o te mōhiotanga ki ngā take taiao me te hauora, kua piki ake te kaha o te hopu kore-taitai, i te nuinga o te wā i ngā mākete o te EU me te US. Ko te konumohe kore-tahu he parahi, he mea whakaranu ki te hiriwa, te parahi, te bismuth rānei. Ahakoa he nui ake te taumata rewa (tata ki te 220-260 °C), ka tutuki i a ia nga whakaritenga ture tino kaha, a he mea pai ake i nga tono hou.

Ngā Mea hei Whakaaro i te Kōwhiri i te Waea Whakapā

Te Honoa o ngā Mea

I te wa e whiriwhiri ana i te waea whakairo, kia tino pai ki ngā rauemi e mahi ana koe. Hei tauira, Hikohiko he maha ngā wā e hiahiatia ana he whakapiri i hangaia mō te parahi, i te mea ngā tono putorino me tūtohu he pūkaha e hāngai ana mō ngā hononga putorino whakarewa.

Te Tapahanga me te Matotoru o te Waea

Ko te diameter o te waea whakawera e pā ana ki te whakawhiti wera me te rahi o ngā hononga whakawera. Ko ngā taura angiangi (he maha noa iho i te 0.5mm) e whakamahia ana mō ngā mahi uaua, i te mea he pai ake ngā taura matotoru (1.0mm me runga ake) mō ngā hononga nui ake. He mea nui te whiriwhiri i te diameter tika hei whakatutuki i tētahi hononga whakapiri kaha, pono hoki.

Te Hoko me te Momo o te Hoko

He mea nui te rere ki te whakawera whai hua nā te mea ka horoia e ia ngā mata e whakawerahia ana, ā, ka pai ake te rere o te whakawera. Ka taea e te waea solder te whai momo rere rerekē, tae atu ki:

• Te whakaranu o te pūāhua o te raima : He pai mō ngā hikohiko. He iti rawa ngā toenga, he māmā ake hoki te horoi.
• Te Hurihi Hū o te Hū : Ka whakamahia i roto i te putunga wai, engari he kino ki te hikohiko nā ōna āhuatanga kai.
• Te wai-waikore o te wai : He māmā ake te horoi, engari me horoi āta hei karo i te waikura.

Ngā Tikanga Pai rawa mō te Whakamahi i te Waea Whakapā

Ngā Tikanga Hei Whiwhi i ngā Tūhono Kaha

Hei hanga i ngā hononga whakapiri kaha, pono hoki, whai i ēnei tikanga:

1. Whakakorea ngā Papa : Me whakarite kia kore ngā mata e whakairihia ana e paru, he hinu, he waikura rānei.
2. Whakamahia te Rāhua Tika : Whakamahia te momo rere tika hei whakatairanga i te rere me te piri o te whakapiri.
3. Te wera whakahaere : Whakamahia he rino whakairi me te mana tika me te pāmahana kia kore ai e wera rawa nga wāhanga.

Ngā Aroturuki i te wā e tūtuku ana

Me pupuri tonu i te haumaru i te wā e whakapiri ana hei tiaki i a koe i ngā mōrearea:

• Whakamahia ngā Karaka Haumaru : Tiakina ō kanohi i te hīkoi o te hīkoi, i ngā kiri.
• Whakamahia te Waea Hauora Tika : Ka kino pea ngā paowa o te taiaho, nō reira kia pai te hau o te wāhi mahi, whakamahi rānei i tētahi pūkaha paowa.
• Whakahaere i ngā Utauta me te Atawhai : Whakatakotoria te rino whakawera wera ki runga i te tūnga wera-aukati ina kore e whakamahia.

Te whakatau

Mā te mōhio ki ngā momo waea me te kōwhiringa o te waea whakairo e pai ake ai ō kaupapa whakairo, ahakoa i roto i te hiko, i te putunga wai, i ētahi atu āpure rānei. Mā te whakaaro ki te hototahi o te rauemi, te diameter waea, me te momo rere, ka taea e koe te whakarite i ngā hononga kounga e tu ana i te whakamātautau o te wā. Mā te whakamahi i ngā tikanga tika me ngā tikanga haumaru, ka angitu, ka ahuareka hoki tō mahi whakairo. Kia hari te whakairi!
