Ka nānā 'ana i ka hana o nā lako SMT nānā 'ike AOI

a): Hoʻohana ʻia no ke ana ʻana i ka mīkini paʻi paʻi paʻi SPI ma hope o ka mīkini paʻi: lawe ʻia ka nānā ʻana o SPI ma hope o ka paʻi ʻana o ka solder paste, a hiki ke ʻike ʻia nā hemahema i ke kaʻina paʻi, a laila e hōʻemi ana i nā hemahema kūʻai i kumu ʻia e ka paʻi solder maikaʻi ʻole. paʻi liʻiliʻi.ʻO nā hemahema o ka paʻi maʻamau, ʻo ia nā mea penei: lawa ʻole a ʻoi aku ka nui o ka solder ma nā pads;paʻi offset;nā alahaka tin ma waena o nā pā;mānoanoa a me ka nui o ka paʻi solder paʻi.I kēia manawa, pono e loaʻa nā ʻikepili nānā kaʻina hana ikaika (SPC), e like me ka paʻi ʻana i ka offset a me ka ʻike leo solder, a e hana pū ʻia ka ʻike qualitative e pili ana i ka solder i paʻi ʻia no ka loiloi a hoʻohana ʻia e nā limahana kaʻina hana.Ma kēiaʻano, hoʻonuiʻia ke kaʻina hana, hoʻonuiʻia ke kaʻina hana, a hoʻemiʻia ke kumukūʻai.Hoʻokaʻawale ʻia kēia ʻano mea hana i nā ʻano 2D a me 3D.ʻAʻole hiki iā 2D ke ana i ka mānoanoa o ka paʻi solder, ʻo ke ʻano o ka paʻi solder wale nō.Hiki iā 3D ke ana i ka mānoanoa o ka paʻi solder a me ka ʻāpana o ka paʻi solder, i hiki ke helu ʻia ka nui o ka paʻi solder.Me ka miniaturization o nā ʻāpana, ʻo ka mānoanoa o ka solder paste i koi ʻia no nā ʻāpana e like me 01005 he 75um wale nō, aʻo ka mānoanoa o nā mea nui maʻamau e pili ana i 130um.Ua puka mai kekahi mīkini paʻi ʻakomi e hiki ke paʻi i nā mānoanoa paʻi solder like ʻole.No laila, hiki i ka 3D SPI ke hoʻokō i nā pono o ke kaʻina kaʻina hana solder paste e hiki mai ana.No laila he aha ke ʻano o ka SPI hiki iā mākou ke hoʻokō maoli i nā pono o ke kaʻina hana i ka wā e hiki mai ana?ʻO ka mea nui kēia mau koi:

1. Pono ʻo 3D.
2. ʻO ka nānā ʻana i ka wikiwiki kiʻekiʻe, pololei ke ana ʻana o ka mānoanoa SPI o kēia manawa, akā ʻaʻole hiki i ka wikiwiki ke hoʻokō pono i nā pono o ka hana.
3. ʻO ka hoʻonui pololei a hiki ke hoʻololi ʻia (ʻo ka optical a me ka digital magnification he mau mea koʻikoʻi nui, hiki i kēia mau ʻāpana ke hoʻoholo i ka hiki ke ʻike hope loa o ka hāmeʻa. Loaʻa ka hoʻonā a me ka ʻike kiʻi i ka algorithm detection i hāʻawi ʻia i ka polokalamu AOI).Eia naʻe, ke hoʻopaʻa ʻia ka pixel kamera, ʻokoʻa ka hoʻonui ʻana i ka FOV, a ʻo ka nui o ka FOV e hoʻopili i ka wikiwiki o ka mīkini.Ma ka papa hoʻokahi, aia nā mea nui a me nā mea liʻiliʻi i ka manawa like, no laila he mea nui e koho i ka hoʻonā optical kūpono a i ʻole ka hoʻoponopono optical adjustable e like me ka nui o nā mea ma ka huahana.
4. ʻO ke kumu kukui koho: ʻo ka hoʻohana ʻana i nā kumu kukui programmable e lilo i mea nui e hōʻoia i ka nui o ka ʻike hemahema.
5. ʻOi aku ka pololei a me ka hoʻihoʻi hou ʻana: ʻO ka miniaturization o nā ʻāpana e hana i ka pololei a me ka hana hou ʻana o nā mea hana i hoʻohana ʻia i ke kaʻina hana.
6. Ka helu kuhi hewa haʻahaʻa haʻahaʻa: Ma ka hoʻomalu wale ʻana i ka helu kuhi hewa kumu hiki ke hoʻohana maoli ʻia ka loaʻa, ke koho a me ka hana o ka ʻike i lawe ʻia e ka mīkini i ke kaʻina hana.
7. ʻO ka nānā ʻana i ke kaʻina hana SPC a me ka kaʻana like ʻana i ka ʻike kīnā me AOI ma nā wahi ʻē aʻe: ka manaʻo o ke kaʻina hana SPC ikaika, ʻo ka pahuhopu hope loa o ka nānā ʻana i nā hiʻohiʻona ʻo ia ka hoʻomaikaʻi ʻana i ke kaʻina hana, noʻonoʻo i ke kaʻina hana, hoʻokō i ka mokuʻāina maikaʻi loa, a me ka mālama ʻana i nā kumukūʻai hana.

b) .AOI i mua o ka umu: Ma muli o ka liʻiliʻi o nā ʻāpana, paʻakikī ke hoʻoponopono ʻana i nā hemahema ʻāpana 0201 ma hope o ke kūʻai ʻana, a ʻaʻole hiki ke hoʻoponopono maoli ʻia nā hemahema o nā ʻāpana 01005.No laila, e lilo ka AOI i mua o ka umu ahi.Hiki i ka AOI i mua o ka umu ahi ke ʻike i nā hemahema o ke kaʻina hana e like me ka misalignment, nā ʻāpana hewa, nā ʻāpana nalo, nā ʻāpana he nui, a me ka polarity hoʻohuli.No laila, pono e online ka AOI i mua o ka umu ahi, a ʻo nā hōʻailona koʻikoʻi he kiʻekiʻe ka wikiwiki, kiʻekiʻe pololei a me ka repeatability, a me ka haʻahaʻa misjudgment.I ka manawa like, hiki iā ia ke kaʻana like i ka ʻikepili ʻikepili me ka ʻōnaehana hānai, ʻike wale i nā ʻāpana hewa o nā mea hoʻopihapiha i ka wā o ka refueling, e hōʻemi ana i ka hōʻike hewa ʻana o ka ʻōnaehana, a hoʻouna pū i ka ʻike deviation o nā ʻāpana i ka ʻōnaehana polokalamu SMT e hoʻololi. ka polokalamu mīkini SMT koke .

c) AOI ma hope o ka umu: AOI ma hope o ka umu ahi i māhele ʻia i ʻelua mau ʻano: ma ka pūnaewele a me ka offline e like me ke ʻano o ke kau ʻana.ʻO ka AOI ma hope o ka umu ahi ke kiaʻi puka hope loa o ka huahana, no laila ʻo ia ka AOI i hoʻohana nui ʻia.Pono ia e ʻike i nā hemahema PCB, nā hemahema ʻāpana a me nā hemahema kaʻina hana āpau i ka laina hana holoʻokoʻa.ʻO ke kumu kukui LED dome ʻekolu kala wale nō e hiki ke hōʻike piha i nā mea hoʻomaʻemaʻe solder e ʻike maikaʻi i nā hemahema.No laila, i ka wā e hiki mai ana, ʻo ka AOI wale nō o kēia kumu kukui ka lumi no ka hoʻomohala ʻana.ʻOiaʻiʻo, i ka wā e hiki mai ana, i mea e hana ai me nā PCB ʻokoʻa ʻO ke ʻano o nā kala a me ʻekolu kala RGB hiki ke hoʻonohonoho ʻia.ʻOi aku ka maʻalahi.No laila he aha ke ʻano o ka AOI ma hope o ka umu e hiki ke hoʻokō i nā pono o kā mākou hoʻomohala hana SMT i ka wā e hiki mai ana?ʻo ia:

1. kiʻekiʻe ka māmā holo.
2. Kiʻekiʻe precision a kiʻekiʻe repeatability.
3. Nā kāmeʻa kiʻekiʻe a i ʻole nā ​​kāmeʻa hoʻonā hoʻololi: hoʻokō i nā koi o ka wikiwiki a me ka pololei i ka manawa like.
4. ʻO ka manaʻo hewa haʻahaʻa a me ka hoʻoholo ʻole: Pono e hoʻomaikaʻi ʻia kēia ma ka polokalamu, a ʻo ka ʻike ʻana i nā ʻano kuʻi ʻana ke kumu o ka manaʻo hewa a hala ʻole ka hoʻoholo.
5. AXI ma hope o ka umu: ʻO nā hemahema i hiki ke nānā ʻia, ʻo ia hoʻi: nā hono solder, nā alahaka, nā pōhaku kupapaʻu, lawa ʻole ka solder, pores, nā ʻāpana nalowale, IC hāpai wāwae, IC liʻiliʻi i ka tin, a pēlā aku. e like me BGA, PLCC, CSP, a me nā mea ʻē aʻe.
