Ko te Tōmstoning me te whakarere he ngoikera huihuinga e āhua hui nei i te wā e huihui ai ngā taputapu hiko. Kātahi ka āhua ngoikera ki te hua mutunga, te whakangāhau me ētahi atu karekau kounga ki ngā taputapu hiko. Engari ka tū kia pai, ki te whanake ake o te hangarau, e āhua tāone ana ki te whakamahi i ngā hangarau matua me te rānei tikanga pērā i te rapu māmā rorohiko me te āki ai i te tāpiripiri me te rānei te tōmstoning e PCB huihuinga.
He aha te tōmstoning me te toe ki ngā wae taputapu hiko katoa
Tombstoning (tombstoning ferrous, te āhua o te hau paripari) Ko te rareretanga o te wāhanga (resistor, capacitor rānei) e tu ana ki te mutunga, ko tētahi mutunga o te wāhanga kua tūhono, ko te mutunga kei te turuki. Kei te āhua tēnei ina kua whakakaha ngā papa tāpahi ki ia taha o te wāhanga kāore i te ū, ā, ka huri i te wāhanga ka puta ai te wehe. Ko te kore whakarite kātahi ka tū ana ko te wāhanga kāore i te tū wāhi tika ki te PCB i te wā o te huihuinga papa. Ko te tombstoning me te kore whakarite e whai ai i ngā raru hiko hoki me te hinonga ki te taputapu hiko.
Te whakawhitinga a AOI mō te kitea i te tombstoning me te kore whakarite
Ko te whakamātau ā-whakaahua ake (AOI) he anga whakamātau e whakarato ana i te roopu whānui o ngā ratonga whakamātau me te whakamātau mō ngā kaihanga huihuinga me ngā kaiwhakarato. Ko te whakaputua o te pōro (tombstoning) me te whakapōhara tōwari e kitea ai mā ngā pūnaha AOI kia mā ia e whakaatu ai i ngā whakaahua o ngā wāhanga ki te paparorohiko (PCB). Kei te whakaatu ngā kamera o ngā pūnaha AOI i ngā whakaahua o te kaha-mōhio o ngā wāhanga ka whakamahia ai ngā rautaki hei whakauru i te tūranga e hiahiatia ana o ngā wāhanga ki tō rātou tūranga irirangi. Mēnā he aha te whakaputua o te pōro, te whakapōhara rānei āwhi whakamahi ka tautuhi i te ngoikera hei āki mō te whakamātau me te whakatika pea.
Te whakamahi i te AI hei Kite me te Neke i te Whakaputua o te Pōro ki te Huihuinga PCB
Kua whakapai ake te tūhono me te tāturi anō hoki i te huihuinga PCB i te whakauru i te aronga hinengaro (AI) ki ngā punaha AOI. Mai i tēnei, ka taea e te rautaki AI te ako i ngā āhua o mua me te whakapai ake i te tautohe i te āhua ki te kaha ake o te tika. Ka taea e te AI te whakamahi i ngā rahi o ngā raraunga hei tūhono i ngā tauā me ngā mea kāore e tāra ana ki te tūhono, ki te tāturi rānei. I runga i tēnei, te pūnaha tirohanga aoi ka taea e te pūnaha te whai wa hiato me te tūhono i ngā wāhi e hē ana me te whakakaha i ngā ngana ki te tuku atu ki te tukatuka o ngā mea kua oti.
Anō ētahi take mō te tāturi me te āwhina a AOI kia kaua ngā āhua e hinga
Ko te tērā pea he maha ngā take e pā ana ki te wehenga o ngā pārti hiko, tae atu ki te whakaputanga kino e te mīhini toa-whakaputanga, te āhuā kāore he ōrite i te wā o te hui kohu, me ngā rerekētanga i te rahi, te āhua rānei o ngā pārti. Ka taea te whakawātea i te wehenga mā te whakamahi i te pūnaha AOI hei tirotiro i ia kaupapa ki runga i te PCB me te whai mōhio ki tana tūranga, ki tana aronga anō hoki. Mēnā he hapa kei te kitea, ko te tirotiro 2D AOI Pūnaha pūnaha ka whakapau mōhio ki te kaiwhakahaere kia whakarewa anō i te wāhanga i mua i te wātene pea ka pā ki te tukanga whakaputa i muri mai. Ko te tātari i ngā wehenga ki tētahi wāhanga i mua i te mutunga o te tukanga hui - hei whakamāmā i taua hapa kia kaua e eke atu ki āu kiritaki.
