Kei te kōrerorero i ngā whakapiri kīnaki e whakamahia ana i roto i te whakanaotanga ā-hiko

Ina tae ki te hanga wae hiko,whakapiri kaihokohe taputapu tino nui e whakaemi ana i ngā PCBs me te whakaū i te āhua o ngā tūhononga hiko. He mea hira tētahi mōhiotanga whānui mō tōna hanganga, ngā pūkenga taupānga me ngā kōkiri hangarau kia taea ai ngā hononga kaihoko kounga pai me te whakaputa māia.

Kupu Whakataki:

Ko ngā whakapiri solder he ranunga matatini e pupuri ana i ngā kaihoko paura tino pai, ngā pūrere me ngā whakatārewatanga. Mā tēnei ka taea te whakanoho tika ki ngā pūwāhi kaihoko PCB e āwhina ana ki te whakapiri i ngā wae maunga mata me te waihanga i ngā ara hiko e hiahiatia ana mō te mahi pūrere.

Hanganga me ngā Momo:

Ko te tikanga, kei roto i tētahi whakapiri kaihoko taketake ko ngā korakora kaihoko (ngā hanganga tīni-kore, ngā hanganga koreutu rānei pēnei i te SAC305), ngā rauemi rewharewha (ngā momo pūtake-wai/kore-kore) me ngā whakakē matarahi kei roto ko ngā here. Kei te āhua tonu te tīpakonga o aua ranunga ki ngā whakaritenga tauwhāiti i te wā o ngā tukanga hoko rerekē pēnei i ngā kōtaha pāmahana, i ngā here whiwhinga rānei.

Taupānga i te Whakanaonga Āhiko:

I roto i te umanga whakanao ā-hiko, ka whakamahia te aratuka tā stencil, ngā taputapu whakakore rānei hei hoatu i te whakapiri kaihoko ki ngā papa arawhiti tā (PCBs). I muri i tērā ka purua ngā wae hangarau maunga mata (SMT) ki ngā PCBs i mua i te haerenga mā te hoko anō ina hanga ngā melts whakapiri i te rere e pā ana ki te rere e pā ana ki te whakatūnga o ngā kaihoko kaihoko e pupuri ana i ngā wāhanga katoa.

Ngā Whakaneketanga Hangarau:

Kua arotahi ngā whakahōutanga o te hokohoko whakapiri ki te whakapiki i te tā, me te whakarite i te ōritetanga ki te kounga hono i a ia e whakarei ana i te whaikikotanga. Ko ēnei he rahi korakora pai ake mō te taumira nui ake i ngā wāhanga iti, he iti iho te whakakore i roto i ngā hononga kaihoko me ngā tātaitanga i whakaritea ki ngā hiahia wātea-ā-ringa me te hoa taiao.

Mana Kounga me te Whakaaro:

Ko ngā wāhi matua o te māharahara e pā ana ki ngā tikanga mana kounga i te wā e hoatu ana i ngā whakapiri kaihoko, kei roto ko te arotautanga hoahoa stencil; SPI mō ngā rōrahi moni tika; Ko te arotakenga rere tōmuri e hāngai ana ki te kite i ngā hēnga pēnei i ngā arawhata i waenganui i ngā kaihoko, i ngā kaihoko iti rānei. He mea nui ēnei ngohe ki te whakarite kia mau tonu ngā paerewa whakanao tiketike me te whaikiko hua.

Hei whakamutu, he wāhanga tino nui te whakapiri kaihoko o ngā tukanga whakanao hiko o nāianei i a ia e āwhina ana ki te tika me te tere. Ka hangaia mō ngā momo taupānga hoko, i te wā e haere tonu ana ngā whanaketanga i tēnei hangarau kia taea ai ngā tūhononga roa – roa puta noa i ngā umanga katoa e mahi ai ngā pūrere hiko.
