Tirohanga Whānui
Tuarua, he pai te mahi wehewehe a te whakawehe SMT. Ka taea e rātou te wehewehe i ngā tohu e tukuna ana me ngā tohu e whiwhihia ana, te ārai i te pokanoa me te pupuri i te pono o te Tohu. Mā te hiranga o tēnei mahi wehewehe ka taea te whakarite i te mahi whai hua o te pūnaha me te whakaiti i te pokanoa o te tohu.
Hei tāpiritanga, he tino pai hoki te pumau o te pāmahana o te whakawehe SMT. Ka taea e rātou te mahi i runga i te whānuitanga o te pāmahana, tae atu ki ngā pāmahana mai i te -40℃ ki te +85℃, tae atu rānei ki te whānui ake. Mā tēnei pumau pāmahana ka taea e te whakawehe SMT te mahi pono i roto i ngā taiao rerekē.
Mā te tikanga tākai o ngā whakawehe SMT ka māmā ake te whakauru me te tāuta. Ka taea e rātou te tāuta tika i ngā taputapu wehewehe ki ngā PCB mā te hangarau whakairi, me te kore e hiahiatia he tikanga whakauru pine tuku iho, he tikanga whakapiri rānei. Ehara i te mea ka whakapai ake i te pai o te whakaputanga anake tēnei tikanga tākai whakairi mata, engari ka taea hoki te whakauru kiato teitei ake, ā, ka penapena wāhi, ka whakangawari ake hoki i te hoahoa pūnaha.
Hei tāpiritanga, he whānuitia te whakamahinga o ngā wehewehe SMD i roto i ngā pūnaha whakawhitiwhiti reo auau-tiketike me ngā taputapu ngaruiti. Ka taea te whakamahi hei wehewehe i ngā tohu i waenga i ngā whakakaha RF me ngā pūihi, hei whakapai ake i te mahi me te pumau o te pūnaha. Hei tāpiritanga, ka taea hoki te whakamahi i ngā wehewehe SMD i roto i ngā taputapu ahokore, pērā i te whakawhitiwhiti reo ahokore, ngā pūnaha radar, me te whakawhitiwhiti reo amiorangi, hei whakatutuki i ngā hiahia o te wehewehe me te wetewete tohu auau-tiketike.
Hei whakarāpopototanga, he taputapu wehewehe iti, māmā, he ngāwari hoki te tāuta i te taputapu wehewehe SMD, he whānui te whānuitanga o te whānuitanga o te auau, he pai te mahi wehewehe, ā, he pumau te pāmahana. He nui ngā whakamahinga o ēnei taputapu i roto i ngā mara pēnei i ngā pūnaha whakawhitiwhiti kōrero auau-tiketike, ngā taputapu ngaruiti, me ngā taputapu reo irirangi. Mā te whanaketanga tonu o te hangarau, ka whai wāhi nui ngā taputapu wehewehe SMD ki ngā mara maha atu, ā, ka whai wāhi atu ki te whanaketanga o te hangarau whakawhitiwhiti kōrero hou.
