Me ka hoʻomohala ʻana o ka miniaturization o nā ʻāpana SMD a me nā koi kiʻekiʻe a kiʻekiʻe o ke kaʻina hana SMT, ʻoi aku ka kiʻekiʻe o ka ʻoihana uila uila i nā koi no ka hoʻāʻo ʻana i nā mea hana.I ka wā e hiki mai ana, pono e loaʻa i nā papa hana SMT nā mea hoʻāʻo ma mua o nā lako hana SMT.ʻO ka hopena hope loa he hui pū ʻana o SPI + AOI ma mua o ka umu + AOI + AXI ma hope o ka umu.
- ʻO ke ʻano o ka miniaturization o nā ʻāpana SMD a me ke koi no nā lako AOI
Me ka holomua o ka lehulehu a me ka hoʻomohala ʻana i ka ʻepekema a me ka ʻenehana, ʻoi aku ka nui o nā mea lawe lima e hālāwai me nā makemake like ʻole o ka poʻe, a ʻoi aku ka maʻalahi o ka hana ʻana, e like me nā headset Bluetooth, PDAs, netbooks, MP4, SD kāleka a pēlā aku.ʻO ka noi no kēia mau huahana ua hoʻoulu i ka hoʻomohala ʻana o ka miniaturization o nā ʻāpana SMD, a ʻo ka miniaturization o nā ʻāpana ua hoʻolaha pū i ka hoʻomohala ʻana i nā polokalamu kelepona.ʻO ke ʻano o ka hoʻomohala ʻana o nā ʻāpana passive SMD e like me kēia: 0603 nā mea i ʻike ʻia i ka makahiki 1983, 0402 nā mea i ʻike ʻia i ka makahiki 1989, 0201 nā mea i hoʻomaka i ka 1999, a i kēia lā ua hoʻomaka mākou e hoʻohana i nā ʻāpana 01005.
Ua hoʻohana mua ʻia nā ʻāpana 01005 i nā lāʻau lapaʻau nui a me nā kumu kūʻai ʻole e like me ka pacemakers.Me ka hana nui o nā ʻāpana 01005, ua hāʻule ke kumukūʻai o nā ʻāpana 01005 i nā manawa 5 i hoʻohālikelike ʻia i ke kumukūʻai i ka wā i hoʻomaka mua ʻia ai, no laila ka hoʻohana ʻana i nā ʻāpana 01005 Me ka hoʻemi ʻana o ke kumukūʻai, hoʻonui mau ʻia ka laulā i nā huahana i loko. nā kahua ʻē aʻe, e hoʻoulu ai i ka puka mau ʻana o nā huahana hou.
Ua ulu nā ʻāpana SMD mai 0402, a i 0201 a laila i 01005. Hōʻike ʻia nā loli nui ma ke kiʻi ma lalo nei.
ʻO ka nui o ka 01005 chip resistor ʻo 0.4 mm × 0.2 mm × 0.2 mm, ʻo ka wahi he 16% a me 44% o nā mea ʻelua ma mua, a ʻo ka leo he 6% a me 30% o nā mea ʻelua.No nā huahana koʻikoʻi nui, ʻo ka kaulana o 01005 ke ola i ka huahana.ʻOiaʻiʻo, lawe mai ia i nā pilikia hou a me nā manawa kūpono i ka ʻoihana hana uila!ʻO ka hana ʻana o nā ʻāpana 01005 a me nā ʻāpana 0201 e kau i nā koi kikoʻī kiʻekiʻe loa ma nā lako hana SMT mai mua a i hope.
No nā ʻāpana 0402, ua paʻakikī loa ka nānā ʻana i ka ʻike a paʻakikī hoʻi e mau, e waiho wale i nā ʻāpana 0201 kaulana a me nā ʻāpana 01005 e kūkulu nei.No laila, he manaʻo ʻenehana ia e pono ai nā laina hana SMT i nā lako AOI no ka nānā ʻana.No nā ʻāpana e like me 0201, inā loaʻa kahi kīnā, hiki ke waiho wale ʻia ma lalo o ka microscope a hoʻoponopono ʻia me nā mea hana kūikawā.No laila, uaʻoi aku ka kiʻekiʻe o ke kumukūʻai mālama ma mua o ka 0402. No nā māhele o ka nui 01005 (0.4 × 0.2 × 0.13mm), he mea paʻakikī keʻike me ka maka'ōlohelohe wale nō, aʻoi aku ka paʻakikī o ka hana a mālamaʻana. me kekahi mea paahana.No laila, inā he hemahema ka ʻāpana 01005 i ke kaʻina hana, hiki ʻole ke hoʻoponopono.No laila, me ka hoʻomohala ʻana o ka miniaturization o nā mea hana, pono mākou i nā mīkini AOI e hoʻokele i ke kaʻina hana, ʻaʻole wale e ʻike i nā huahana hemahema.Ma kēia ala, hiki iā mākou ke ʻike i nā hemahema i ke kaʻina hana i ka hiki wawe, hoʻomaikaʻi i ke kaʻina hana, a hōʻemi i ka hiki ʻana mai o nā hewa.
- Ma kēia ala, hiki iā mākou ke ʻike i nā hemahema i ke kaʻina hana i ka hiki wawe, hoʻomaikaʻi i ke kaʻina hana, a hōʻemi i ka hiki ʻana mai o nā hewa.
ʻOiai ua hoʻokumu ʻia nā mea hana AOI he 20 mau makahiki i hala aku nei, no ka manawa lōʻihi, he pipiʻi a paʻakikī ke ʻike, a ʻaʻole ʻoluʻolu nā hopena ʻike.Ua noho wale ʻo AOI ma ke ʻano he manaʻo a ʻaʻole i ʻike ʻia e ka mākeke.Eia naʻe, mai ka makahiki 2005, ua ulu wikiwiki ʻo AOI.Ua ulu mai nā mea hoʻolako lako AOI.Ua puka mai nā manaʻo hou like ʻole a me nā huahana hou.ʻO ka mea kūikawā, ʻo nā mea hana lako AOI kūloko ka haʻaheo o Kina's SMT 'oihana, a me ka home AOI lako i hoʻohana 'ia.ʻO ka hopena, ʻaʻole ia i piʻi a i lalo me nā huahana o nā ʻāina ʻē, a no ka piʻi ʻana o ka AOI kūloko, ua hāʻule ke kumukūʻai holoʻokoʻa o AOI i 1/2 a 1/3 o ka mua.No laila, ma ka olelo o ka hana koina i hoola ia e AOI ma kahi o ka manual hiʻona nana, kuai AOI mea no hoi He mea pono, aole e olelo i ka hoʻohana 'ana i ka AOI hiki ke hoʻonui i ka pololei-ma ka helu o ka huahana a loaʻa i ka oi paʻa 'ike hopena ma mua. manual.No laila he mea pono ʻo AOI no nā mea hana hana SMT o kēia manawa.
Ma lalo o nā kūlana maʻamau, hiki ke hoʻonoho ʻia ʻo AOI i 3 mau kūlana i ke kaʻina hana SMT, ma hope o ka paʻi ʻana i ka solder paste, ma mua o ka reflow soldering a ma hope o ka reflow soldering e nānā i ka maikaʻi o nā ʻāpana like ʻole.ʻOiai ua lilo ka hoʻohana ʻana o AOI i mea maʻamau, ʻo ka hapa nui o nā mea hana e hoʻokomo wale iā AOI ma hope o ka umu ahi, a hoʻohana iā AOI e like me ke kiaʻi puka hope loa no ka huahana e kahe i ka ʻāpana aʻe, ma kahi o ka nānā ʻana i ka manual.Eia kekahi, nui nā mea hana i kuhi hewa ʻole e pili ana iā AOI.ʻAʻole hiki i ka AOI ke hoʻokō i ka hoʻāʻo wahaheʻe, a ʻaʻole hiki i ka AOI ke hoʻokō i ka hoʻāʻo hala ʻole.ʻO ka hapa nui o nā AOI e koho i ke kaulike kūpono ma waena o ka ho'āʻo hoʻopunipuni a me ka hoʻāʻo i hala, no ka mea, ʻo ka algorithm o AOI kekahi ala.E hoʻohālikelike i ka laʻana o kēia manawa me ka laʻana kamepiula (he kiʻi a i ʻole ka palena), a hana i ka hoʻoholo ma muli o ka like.
I kēia manawa, nui nā kihi make ma ka AOI ma hope o ka hoʻohana ʻana i ka umu.No ka laʻana, hiki i ka AOI lens hoʻokahi ke ʻike i kahi hapa o QFP, SOP, a me ka wili hoʻopunipuni.Eia naʻe, ʻo 30% ka kiʻekiʻe o ka ʻike ʻana o nā AOI nui-lens no ka QFP a me ka SOP i hāpai ʻia a me ka liʻiliʻi o ka tin ma mua o ka AOI pākahi-lens, akā hoʻonui ia i ke kumukūʻai o AOI a me ka paʻakikī o ka hana ʻana i nā polokalamu.Hana ʻia kēia mau kiʻi me ka ʻike maka.ʻAʻole mana ʻo AOI e ʻike i nā hui solder i ʻike ʻole ʻia e like me ka BGA nalo pōpō a me ka PLCC hoʻopunipuni hoʻopunipuni.
