Me pēhea te Rapu i ngā Hapa Whakanoho SMD e te Miihini Tirohanga Aunoa
He mea nui ngā mīhini Tirohanga Optical Aunoa, ngā mīhini AOI rānei, hei whakarite kia tika te whakatakoto i ngā wāhanga o te Pūrere Whakatūnga Mata (SMD) ki runga i ngā papa ara i tā. E whakaatu ana ēnei pūnaha i tētahi hangarau tirotiro motuhake e taea ai te whakamahi mō te kitenga hapa i te wā e whakatakotoria ana te SMD, ā, ka whai wāhi ki te hanga i ngā hikohiko kounga teitei.
Ngā Āhua
He mea nui kia ako whānui te tūranga o te āwhi whakamahi ki te pupuri i te tika o te whakanoho SMD. Mēnā ka whakairihia ngā wāhanga hiko ki tētahi papa ara iahiko, me tika te whakatakoto i a rātau kia pai ai te mahi o te hua. Ka whakamahia e ngā mīhini AOI ngā kāmera me ngā pūmanawa taumata tiketike hei tātari i ngā papa ara iahiko me te whakapūtā i te whakatakotoranga tika o ngā wāhanga SMD. Mā tēnei e āhei ai te hanga ki te kimi me te whakatika i ngā raruraru i mua i te hanga katoa o te hua.
He hangarau tino whakamīharo ngā mīhini AOI. Ka tangohia e ēnei mīhini ngā whakaahua teitei o ngā PCB ki te taumata mikron. I muri iho ka tukatukahia ngā whakaahua e tētahi pūmanawa motuhake e kaha ana ki te hopu i ngā hapa iti rawa o te whakanohoanga o ngā wāhanga. I muri iho ka whakatauritea ngā whakaahua ki tētahi tauira kua whakaritea i mua o te papa ara iahiko, e āhei ai te mīhini ki te kite i ngā rerekētanga me ngā hapa pea.
Painga
Ko ngā momo tino noa o te hapa SMD whakatakoto e taea te kitea e pūnaha tirohanga aoi kei roto i ngā wāhanga e ngaro ana, e kore e tika te whakanoho, he hē te whakatakotoranga o ngā wāhanga, he rerenga rerenga rerenga rānei. Ka puta te ngaro o tētahi wāhanga ina kore e tika kia noho tētahi wāhanga ki runga i te PCB. Ko ngā wāhanga kua ngaro te wāhi, ko ngā pūāhua e whakanohoia ana ki te wāhi hē. Ko ngā wāhanga hurihuri ko ngā mea e whakatakotoria ana ki muri, ki te aronga hurihuri rānei. Ka taea e te whakahiato kino te hua i te ngoikore, i te ngaro rānei o ngā hononga ka puta ai te ngoikoretanga o te hua.
Ka whakapiki ake ngā pūnaha AOI i te hua mā te tautuhi i ngā hapa i te tīmatanga o te hanga. Mā te tere o te kitenga me te whakatika i ngā hapa, ka taea hoki e ngā kaihanga te whakaora i te wā me ngā rauemi e tika ana kia whakangao anōtia ki te mahi anō, ki te whakatika rānei i ngā hua he hapa. Mā tēnei ka taea ai e te kaihanga me te kaihoko te whai hua i te whakapiki ake i te hua me te hanga iti iho.
Painga
He maha ngā painga e whakaratohia ana e te I mātāpuna tāone a Aoi he mīhini hei whakahaere i te kounga i roto i te hanga raupapa SMD. Ka āwhina ēnei mīhini ki te whakarite kia pai te kounga o ngā hua, engari ka tutuki i a rātou te āhua o te kounga pai mā te whakaiti i te tūponotanga o ngā hapa e pā ana ki te whakanoho i ngā wāhanga. Mā te kimi wawe i ngā hapa hoahoa me te whakatika, ka taea e ngā kaiwhakanao te karo i ngā hapa utu nui, ā, ka hangaia he pūnaha hiko pono. I te nuinga o te wā, ka tino whakapai ake ngā mīhini AOI i te kounga me te tōtika o ngā mahi whakakotahi SMD.
